Beyond protein intake: bushmeat as source of micronutrients in the Amazon
Provedor de dados: 7

Wild meat is critical for the food security and income of millions of people, especially for poor rural households. Its role as a primary source of macronutrients worldwide has been recognized, but there have been few attempts to evaluate the contribution of bushmeat consumption to micronutrient intake. This is so particularly in the context of nutritional transitions induced by modernization and globalization. Here, we calculated the role of bushmeat as a source of micronutrients in the diets of urban and peri-urban inhabitants within the Tres Fronteras (Peru, Brazil, Colombia) region in the Amazon. We gathered food intake data from 35 households using 3-day 24-h food recalls combined with food weighing. Additionally, we interviewed 105 households on food...

Autores: Butler, Colin D; Australian National University; colin.butler@anu.edu.au; Oluoch-Kosura, Willis; University of Nairobi; Willis.Kosura@aercafrica.org.
Ecosystem services are necessary, yet not sufficient for human well-being (however defined). Insufficient access to the ecosystem provisioning service of food is a particularly important factor in the loss of human well-being, but all ecosystem services contribute in some way to well-being. Although perhaps long obvious to ecologists, the links between ecosystems and aspects of human well-being, including health, have been less well understood among the social science community. This situation may now be starting to change, thanks in part to the Millennium Ecosystem Assessment (MA). Causality between ecosystem services and well-being is bidirectional; it is increasingly clear that functioning societies can protect or enhance ecosystem services, and...

ABSTRACT Increasing potato yield while saving natural resources is a challenge for all those involved in the potato production chain. A field experiment was carried out in order to evaluate the effect of different levels of fertilization, mass of seed tubers and the water regime on the production of potato cv. Orchestra. We tested fertilization methods (F1= conventional fertilization; F2= fertigation according to the rate of absorption by the crop; F3= fertigation split into 3 applications), seed tuber mass (ST1= &lt;50 g; ST2= &gt;50 g), and water regimes [WR1= 50%; WR2= 100% replacement of crop evapotranspiration (ETc)]. The study was conducted using a split-plot randomized block design, with fertilizers in the plot and seed tuber mass in the subplot,...

A mangueira (Mangifera indica L.) é considerada uma das mais importantes fruteiras tropicais cultivadas no mundo, se posicionando, logo depois da banana, do abacaxi e do abacate. Existem poucos estudos sobre as suas exigências nutricionais, devido a dificuldade de conduzir experimentos com esta cultura e também a informações existentes na literatura de que a mangueira é muito eficiente em absorver nutrientes e praticamente não responder a adubação.

Nutricao e adubacao do coqueiro.
Provedor de dados: 14
Autores: SILVA, D. J.
o coqueiro (Cocus nucifera L.) é uma palmeira frutífera de estipe cilíndrico e folhas pecioladas. Possui uma ampla capacidade de adaptação em termos de clima e solo. Esta cultura apresenta uma característica bastante interessante, que é a produção contínua durante toda a sua vida útil. Isto permite ao produtor abastecer o mercado consumidor durante todo o ano. Contudo, para que sejam obtidas altas produtividades, toma-se necessário a realização de adubações equilibradas, uma vez que, o coqueiro 'apresenta urna alta demanda de nutrientes, além da utilização de mudas de alta qualidade genética, uso de irrigação e um rígido controle fitossanitário.

Autores: Geay, Florian.
In the context of the fish farming industry needing to substitute the animal food (meal and oil) by vegetable ingredients, the main objective of this thesis was to study the long-term effects of a diet exclusively composed by plant products on the metabolism of the european sea bass (Dicentrarchus labrax) and more particularly, on its capacity to biosynthesis the Highly Unsaturated Fatty Acids (HUFA) from the PolyUnsaturated Fatty acids (PUFA) brought by this vegetal diet. Our transcriptomic approaches showed that the use of a plant food disrupted the lipids metabolism (cholesterol and fatty acids) and the energy metabolism (carbohydrates, amino acids) in the liver, but also affected other physiological processes such as the immune system. In spite of the...

Biologie et écotoxicologie des véligères de Crassostrea Gigas (Thunberg) dans le bassin d'Arcachon
Provedor de dados: 5
Autores: His, Edouard.
This study analyses the larval recruitment and biology in Crassostrea Gigas, in the Arcachon Bay. Three types of observations were conducted: - a study of the reproduction anomalies in C. gigas between 1976 and 1981. - observations of the particulate nutrition of the veligeres. - ecotoxicologic experiments (organostannic action on oyster reproduction, mostly). The reproduction anomalies in C. gigas could not be attributed to either the genitors' quality or the water quality in the Arcachon Bay, but to a perturbation of the veligeres' trophic regime; the hypothesis of an alteration of the nanoplancton in the Bay, during the summer period, and linked to the action of the organotins is highly considered. The assumption of responsibility of the particulate...

Identification of Hypoxia-Regulated Genes in the Liver of Common Sole (Solea solea ) Fed Different Dietary Lipid Contents
Provedor de dados: 5
Autores: Mazurais, David; Ferraresso, Serena; Gatta, Pier Paolo; Desbruyeres, Elisabeth; Severe, Armelle; Corporeau, Charlotte; Claireaux, Guy; Bargelloni, Luca; Zambonino, Jose-luis.
Coastal systems could be affected by hypoxic events brought about by global change. These areas are essential nursery habitats for several fish species including the common sole (Solea solea L.). Tolerance of fish to hypoxia depends on species and also on their physiological condition and nutritional status. Indeed, high dietary lipid content has been recently shown to negatively impact the resistance of sole to a severe hypoxic challenge. In order to study the molecular mechanisms involved in the early response to hypoxic stress, the present work examined the hepatic transcriptome in common sole fed diets with low and high lipid content, exposed to severe hypoxia. The activity of AMP-activated protein kinase (AMPK) was also investigated through the...

Lipid requirements of the scallop Pecten maximus (L.) during larval and post-larval development in relation to addition of Rhodomonas sauna in diet
Provedor de dados: 5
Autores: Gagne, Renee; Tremblay, Rejean; Pernet, Fabrice; Miner, Philippe; Samain, Jean-francois; Olivier, Frederic.
The main objective of this study was to evaluate the effect of the addition of Rhodomonas salina in the diet of Pecten maximus on growth, survival and metamorphosis success in relation to biochemical content. Food quality is an essential factor in the success of larval, post-larval and juvenile development. A diet rich in polyunsaturated fatty acids present an advantage for growth, survival and metamorphosis success. Larvae and post-larvae fed with the diet containing R. sauna showed a higher accumulation of arachidonic acid (20:4n-6) and generally a lower concentration of docosahexaenoic acid (22:6n-3). Addition of R. sauna in diet was related with higher level of eicosapentaenoic acid (20:5n-3) in larval stages, but lower level in post-larvae. Addition...

Traditional oyster culture in France
Provedor de dados: 5
Autores: Heral, Maurice.
The indigenous oyster of mainland France, the fiat oyster, Ostrea edulis has been part of the human diet for centuries. The Romans collected them and exported them to Rome. Although tanks for holding oysters after harvesting were in use at that time (GreIon 1978) it seems that true culture was not developed along the coast contrary to the records of Pliny the Older. It appears that oysters were already being captured on hoards off the Italian coast. The exploitation of natural stocks continued through the Middle Ages and the Renaissance. However, it was not until the 17th century that oyster culture began, first in the pools of the salt marshes of the Atlantic coast and then in specially managed ponds. Papy (1941) repeats a good description given in 1688...

Use of lipids to study the trophic ecology of deep-sea xenophyophores
Provedor de dados: 5
Autores: Laureillard, J; Mejanelle, L; Sibuet, Myriam.
Xenophyophores, widespread giant deep-sea protists, dominate the megafaunal organisms visible on the seafloor in some areas. Owing to the extreme fragility of their tests (external part), little is known about them, and their diet is largely a matter of speculation. The extensive accumulation of fecal pellets (stercomes) within their tests attests to the degree to which xenophyophores feed on particulate matter. During the EUMELI 2 cruise, xenophyophores were recovered intact at the surface of box-cores from an abyssal mesotrophic site in the northeastern Atlantic. They were identified as Syringammina corbicula. In our study, we compare the lipid composition of xenophyophores collected at the top of cores with sediment from the same mesotrophic environment...

Hypoxia tolerance of common sole juveniles depends on dietary regime and temperature at the larval stage: evidence for environmental conditioning
Provedor de dados: 5
Autores: Zambonino, Jose-luis; Claireaux, Guy; Ernande, Bruno; Quazuguel, Patrick; Severe, Armelle; Huelvan, Christine; Mazurais, David.
An individual's environmental history may have delayed effects on its physiology and life history at later stages in life because of irreversible plastic responses of early ontogenesis to environmental conditions. We chose a marine fish, the common sole, as a model species to study these effects, because it inhabits shallow marine areas highly exposed to environmental changes. We tested whether temperature and trophic conditions experienced during the larval stage had delayed effects on life-history traits and resistance to hypoxia at the juvenile stage. We thus examined the combined effect of global warming and hypoxia in coastal waters, which are potential stressors to many estuarine and coastal marine fishes. Elevated temperature and better trophic...

Nutrition chez des copepodes en milieu lagunaire mediterraneen en fonction de la concentration en particules et de la temperature
Provedor de dados: 5
Autores: Gaudy, R; Pagano, M.
The zooplankton of an eutrophic brackish lagoon (Etang de Berre), near Marseille (France) was studied during an annual cycle. It was characterized by large populations of a pelagic copepod (Acartia tonsa ). Grazing on natural particles by this species was investigated. Adults were able to use an extended range of particle sizes, but showed selectivity for particles concentration was observed (14 mu m). Temperature and particles concentration appear to modify the selectivity behavior. Juvenile stages could also catch particles of various size but did not show the same selectivity for the peak particles as adults. Daily food ration was high comparatively to open-sea copepods. Taking into account several results obtained on food ration, egg production and...

Changements ontogéniques de la condition larvaire chez une espèce de poisson à reproduction hivernale, le hareng des Downs
Provedor de dados: 5
Autores: Denis, Jeremy.
The larval condition of Downs herring during the critical period was investigated between 2008 and 2015 in the eastern English Channel and Southern Bight of North Sea from data collected during the International Bottom Trawl Survey (IBTS). First, the study of the feeding strategy from gut contents analysis using two complementary approaches (electronical microscopy and measure of fluorescence) revealed a shift in the feeding diet occurring at a larval size of 13 mm. Smaller larvae had an omnivorous and a more diversified diet composed of numerous protist and small zooplanktonic preys whereas bigger larvae had a less diversified diet composed mainly of bigger zooplanktonic prey. Along with the diet shift, combination of four condition indices (ingestion...

Autores: His, Edouard; Robert, Rene.
"Il est impossible d'imaginer un lieu plus favorable à l'ostréiculture que le bassin d'Arcachon" (Yonge, 1950). En effet, l'huître indigène, Ostrea edulis, et l'espèce plus récemment introduite, Crassostrea gigas, peuvent s'y reproduire en abondant. Si l'exploitation de la première a pris fin à la suite de deux épizooties consécutives, la seconde est l'objet d'une culture intensive dont la production annuelle est d'environ 12 000 tonnes de mollusques commercialisés. Des anomalies ont sévi dans la baie, de 1977 à 1981, rendant les récoltes de naissain pratiquement sensibles aux facteurs d'agression, et ont même été proposées par Woelke (1967) comme matériel biologique, afin de tester la qualité des eaux en zone littorale.

Influence de l'environnement trophique de l'élevage en biofloc sur les performances physiologiques de la crevette Litopenaeus stylirostris : Étude de paramètres de la nutrition, de l'immunité et de la reproduction
Provedor de dados: 5
Autores: Cardona, Emilie.
Biofloc is an intensive rearing system with zero or minimal water exchange where a diverse population of microorganisms (microalgae, zooplankton and bacteria) develops in association with organic matter to form the floc particles. These particles play the double role of biological filter and dietary supplement. This dissertation aims to better understand the process of this rearing system and its interactions with the Litopenaeus stylirostris shrimp. Two specific objectives were integrated within the framework of this general objective: (i) to measure the production gain from biofloc rearing and (ii) to study the interaction between biofloc environment and shrimp and to assess its role on production performances of shrimps.

The Digestive Function of Pseudoplatystoma punctifer Early Juveniles Is Differentially Modulated by Dietary Protein, Lipid and Carbohydrate Content and Their Ratios
Provedor de dados: 5
Autores: Castro-ruiz, Diana; Andree, Karl B.; Solovyev, Mikhail M.; Fernández-méndez, Christian; García-dávila, Carmen; Cahu, Chantal; Gisbert, Enric; Darias, Maria J.
Pseudoplatystoma punctifer is an Amazonian catfish highly appreciated for its high flesh quality, size, and commercial value. Its aquaculture is pursued to satisfy the demands of an increasing population in the region. However, knowledge of the nutritional needs during the early life stages is necessary for improving growth and reducing the incidence of cannibalism, factors that limit the success of its commercial farming. This study aimed at evaluating the influence of four diets containing different protein and lipid levels (30:15, 30:10, 45:15, or 45:10 in %) in the digestive physiology and performance of early juveniles. The results showed that the dietary protein:lipid as well as carbohydrate levels and ratios influenced differently the whole-body...

Adenylatc Encrgy Charge (AEC) values of Crassostrea gigas (9 and 18 months old) cultured in ponds in Marennes-Oléron Bay (Atlantic coast, France) are reported. Two ponds were loaded with two different initial oyster biomasses in order to obtain different food conditions. The growth of oysters was different in the two ponds which corroborated the effectivences of attaining different food conditions. AEC level was different depending on the pond and was therefore related to food availability per unit oyster biomass. Well-fed oysters exhibited greater AEC values than poorly-fed oysters, throughout thc study. Information on nutritional situations for wild or cultured populations can therefore be obtained by AEC. In cach pond, the seasonal AEC variations were...

A twice monthly study shows that the major amount of organic material is from detrtic origin, and is brought in winter, when valeus of mineral seston are very high. In the sping time, phytoplancton blooms, do not make up for lack of detritic material where as in the summer, oceanic phytoplancton is composed of important amounts of carbohydrates. Available food is defined as sum of protids, lipids and carbohydrates and mesured in energetic therms. This allows to foretell the amount of food that molluscs ar likely to assimilate.

Zooplankton nutrition study under conditions close to natural with the use of radioactive phosphorus
Provedor de dados: 5
Autores: Pavlovskaya, T; Zesenko, A.
Lack of a sensitive method for in situ study of the nutrition quantitative characteristics (and food balance in particular) for zooplankton populations in low-productivity regions was the reason for developing one. For the basis of such a method the authors selected the property of radioactive phosphorus isotopes of fast and effective embedding into all plankton components. The method described above allowed not only to quantitatively determine the consumption and transportation of a substance by individual species and populations of zooplankton; it opens new horizons for investigation of the zooplanktonic association role in regeneration of mineral phosphorus.

Hepatic phosphoenolpyruvate carboxykinase gene expression is not repressed by dietary carbohydrates in rainbow trout (Oncorhynchus mykiss)
Provedor de dados: 5
Autores: Panserat, Stéphane; Plagnes Juan, E; Breque, Jeanine; Kaushik, Sadasivam.
Phosphoenolpyruvate carboxykinase (PEPCK) is a rate-limiting enzyme in hepatic gluconeogenesis and therefore plays a central role in glucose homeostasis. The aim of this study was to analyse the nutritional regulation of PEPCK gene expression in rainbow trout (Oncorhynchus mykiss), which are known to use dietary carbohydrates poorly. A full-length hepatic PEPCK cDNA (2637 base pairs with one open reading frame putatively encoding a 635-residue protein) was cloned and found to be highly homologous to mammalian PEPCKs. The presence of a putative peptide signal specific to a mitochondrial-type PEPCK in the deduced amino acid sequence suggests that this PEPCK gene codes for a mitochondrial form, In gluconeogenic tissues such as liver, kidney and intestine,...

Based on Coulter Counter data, a new method is proposed to study the influence of the polymorphous variability in size as well as in shape of the diatom species Skeletonema costatum on the physiological performances of the Manila clam Ruditapes philippinarum . Three conditions are required in order to convert volumetric data determined with the Coulter Counter into metric data, i.e. (1) stability of the pervalvar diameter of the diatom chains, (2) statistical independence between length and pervalvar diameter of the diatom chains, and (3) negligible level of coincident passages through the aperture orifice. Under these three conditions, the mean length (l) of a S. costatum chain can be related to the mean pervalvar diameter (d) of diatom chains and to the...

Autores: Luguet, P; Moreau, Y.
If warmwater finfish protein requirements as level in diet is low, absolute intake per day is similar to those of coldwater species. But relation of this requirement with specific growth rate differs for strictly warmwater fishes as Tilapias. Analysis of partition between protein and non-protein energy retention shows that these species with Clarias make a better use of non-protein energy provided and consequently improve their protein retention. Better carbohydrate digestibility and metabolism are propounded as part of the explanation.

This study examines the effects of varying dietary lipids on growth, survival, lipid composition and behaviour in lobster Homarus americanus (Milne Edwards, 1837) postlarvae. Lobsters were fed one of 3 diets during their early ontogeny: (1) Artemac, a widely used Artemia replacement; (2) a ternary mixture consisting of Artemac, frozen Artemia adults and Artemia flakes; or (3) a mixture of live A. salina nauplii and adults. We evaluated the olfactory capacity (response to predator odour plume) and cryptic behaviour (ability to hide during settlement) of lobster postlarvae as a function of these diets and the lipid and the fatty acid composition of lobsters. Growth and survival of lobster postlarvae were highest in those fed live Artemia, followed by the...

A 30-day trial was performed to evaluate the reproductive performance of wild and 2nd generation domesticated Farfantepenaeus duorarum broodstock. Changes in biochemical composition and fatty acids (FA) profile in the 1st and 4th spawn order females were used as indicators of nutritional condition. Wild population of F. duorarum presented significantly better reproductive outcomes as compared to domesticated ones. Wild spawners achieved significantly higher number of eggs per spawn, number of egg per spawn per g of spawner's body weight and number of nauplii per spawn (P&lt;0.05). Latency period was significantly shorter (P&lt;0.05) for wild than for domesticated females (11 vs 17 days). Wild spawners also presented less mortality (6 vs 12%), higher number...

The effects of fish hydrolysate (CPSP) level on Octopus maya (Voss and Solis) diet: Digestive enzyme activity, blood metabolites, and energy balance
Provedor de dados: 5
Autores: Aguila, J; Cuzon, Gerard; Pascual, C; Domingues, P; Gaxiola, G; Sanchez, A; Maldonado, T; Rosas, C.
As has been demonstrated in previous studies, Octopus maya can be fed on artificial diets. In the present study six different diets were assayed. Five diets were designed to test the effect of percentage of inclusion of fish protein concentrate (CPSP: 0, 5, 10, 15, and 20%) and were offered to octopuses as a specifically designed artificial diet. The sixth diet consisted of frozen crab (Callinectes spp) and was used as control diet. Blood metabolites and energy budget of octopuses were evaluated to determine how CPSP levels modulate the digestive capacity and allow retaining energy for growth. Wild animals (316.4 +/- 9.8 g) were used in the study. Results showed that CPSP produced a positive specific growth rate (SGR, % day(-1)) with high value in...

Modulation des paramètres hémocytaires par la nutrition de l'huitre creuse Crassostrea gigas. Implication dans les mortalités estivales
Provedor de dados: 5
Autores: Delaporte, Maryse.
In the context of Pacific oyster C. gigas summer mortality, the present study demonstrated that the reproductive effort reduced not only the energetic parameters (carbohydrates and CEA) but also the immune parameters (concentration, phagocytosis and adhesive capacity of hemocytes). Increasing food supply from 4% to 12% (of oyster dry weight) did not counteract this phenomena as most of the additional energy was dedicated to the gametogenesis processes. However, after the gametogenesis, the 12% diet clearly favored energy storage restoration and hemocyte production. Hemocyte parameters were also modulated by the food quality. Indeed, hemocyte concentration tended to increase 20:5n-3 and/or 20:4n-6 were supplied by micro-algae or artificial diets. When these...

In the frame of MOREST project, a common biological material, resulting of a mixture of different families produced in experimental hatchery, was reared in two different environmental fields : Normandy and Charente. Concomitantly, a pool was conditioned at the Ifremer Argenton hatchery with three different algae levels : 4%, 8% and 12% of algal dry weight per oyster dry weight. During the experiments, five immune parameters were studied in parallel with survival rate and reproductive status (stages and intensity). Site location, seasonal variations and experimental diet level clearly influenced oyster immune parameters. Haemocyte counts were higher for oysters reared in Normandy than those reared in Charente and in hatchery. Granulocyte percentage was...

Enrichment of live foods.
Provedor de dados: 5
Autores: Watanabe, T.
Live foods such rotifers and Artemia are still indispensable for mass propagation of larval fish. At present, more than 20 fish and crustacean species are mass produced in Japanese governmental fish farming centres and private hatcheries. Fry are either released into the coastal areas or used for commercial cultivation. This culture technology is rapidly developing with new species being introduced each year and larval rearing is increasingly identified as the number one constraint. Artemia is used most extensively, particularly for the mass production of Kuruma prawn, Penaeus japonicus .

Bacteries associees aux production de Brachionus plicatilis
Provedor de dados: 5
Autores: Nicolas, Jean-louis; Joubert, M.
Bacteria associated with semi-continuous culture of Brachionus plicatilis , which is used as the first food of marine fish larvae, were counted on Zobell 2216 E medium and identified. The numbers of bacteria were very high in both Brachionus (about 10 super(11) bact. per ml of digestive content) and in water (from 1.6.10 super(6) to 4.7.10 super(7) bact. per ml). The cultures were studied at driving a time when mortalities occurred frequently. The introduction of a Pseudomonas) phenon at a proportion of about 50% to the dominant microflora persisted in time and was little influenced by diet. It has been the cause of the repression of the Vibrio, Aeromonas group which was found in an unusually small proportion. It induced a lack of microflora diversity and...

L'activite de deplacement et le reperage de la nourriture chez le bar juvenile captif
Provedor de dados: 5
Autores: Anthouard, M; Paris, J.
Movement activity and localization of food were studied dynamically with the objective of establishing the capacities of behavioral adaptation of the young Dicentrarchus labrax faced with a novel situation. The role played by previous rearing conditions was demonstrated, the level of stimulation being a sensitive intervening factor (currents associated with the food). The data show the favourable effects of such treatment, and are in agreement with work carried out on higher vertebrates, which have brought to light the importance of early stimulation in behavioral ontogeny which respect to emotionality as well as capacities of adaptation in subjects reaching adulthood.

Nutrional inadequacy of Nannochloris atomus and Stichoccocucs bacillaris for the oyster Crassostre gigas (Thunberg) larvae
Provedor de dados: 5
Autores: Robert, Rene.
The evaluation of Nannochloris atomliS and StichoccocllS bacillaris as nutrient sources for oyster larvae has been attempted in the present work. After a study of their grawth and size distributions, these two species were used as food for Crassostrea gigas larvae. Despite praper sizes (2.5 to 20 µm3) the larval development of Crassostrea gigas was poor. Evaluation of ingestion and digestion of both algae, by means of epifluorescence microscopy, on 2 day and 6 day old larvae showed that they were normally ingested but weakly digested. Consequently, their nutritional inadequacy for larval molluscs may be also related to their indigestibility.

Is it possible to raise, offspring of the 25th generation of Litopenaeus vannamei (Boone) and 18th generation Litopenaeus stylirostris (Stimpson) in clear water to 40 g?
Provedor de dados: 5
Autores: Cuzon, Gerard; Arena, Leticia; Goguenheim, Jean; Goyard, Emmanuel.
Peneid shrimp are commonly reared in clear-water aquaria or tanks for short-term studies of 4-6 weeks during controlled experiments, such as nutrition studies to estimate dietary nutrient requirements. Recently, in line with the genetic program at Centre Oceanologique du Pacifique (COP), experimental clear-water facilities were tested for the first time over a longer rearing period. Environmental conditions used to maintain animal growth in clear-water system using a well-balanced diet were defined. After 100 days, shrimp growth rates tended to decrease and only by adjusting the diet could shrimp complete their life cycle and reach maturation size of around 40 g. This paper presents information on stocking density, diet quality and husbandry linked to...

Croissance des larves de Crassostrea gigas et de Mytilus galloprovincialis en présence d'algues monocellulaires isolées du tractus digestif des véligères du milieu naturel
Provedor de dados: 5
Autores: His, Edouard; Robert, Rene.
The collection of Crassostrea gigas veligeres in their natural environment and the homogenate technique (HIS et al., 1985) enable the monospecific culture of nine algae which larvae feed on. Four of them could be mass-produced: Nannochloris atomus, Stichococcus bacillaris, Chlamidomonas bullosa and Tetraselmis Tetrathele. Their feeding quality has been tested using the cross-growth method, and using Crassostrea gigas and Mytilus galloprovincialis veligeres. Although regularly found in the homogenates, and thus fed on by larvae, the first three algae gave poor results. Only Tetraselmis tetrathele has good nutritional qualities for Crassostrea gigas veligeres.

Microalgues et nutrition  larvaire en écloserie de mollusques
Provedor de dados: 5
Autores: Robert, Rene; Trintignac, Pascal.
The production of live microalgae remains the only reliable technique for feeding bivalve mollusc larvae in a controlled environment. However, these algae must answer a number of size, nutritive value and mass-production criteria. The current knowledge in this field is assessed in this work which will lead us to the conclusion that only a few species meet these requirements.

Autores: Cahu, Chantal.
This report is presented by Chantal Cahu for obtaining accreditation to supervise research. Since 1981, her research activity has addressed the study of reproducers' nutrition and the young stages of development of marine organisms belonging to two different branch lines, crustaceans and fish. This work, performed in a base-lined research body, IFREMER, is placed within a more general programme of aquaculture development. Indeed, whatever species are at issue, the development of aquaculture in France, as at the global level, is based on the production of juveniles in hatcheries. My work has therefore more precisely the goal of acquiring knowledge about the nutritional needs, mechanisms of digestion and the development of these animals in order to improve...

Autores: Tremblay, Rejean; Cartier, Simon; Miner, Philippe; Pernet, Fabrice; Quere, Claudie; Moal, Jeanne; Muzellec, Marie-louise; Mazuret, Michel; Samain, Jean-francois.
The main objective of this study was to identify algal diets that maximize the survival and growth and alter the biochemical content of Pecten maximus larvae with the aim of improving metamorphosis. We also evaluated the potential of the cryptophyceae Rhodomonas salina as a food source for these larvae. Two flagellates, Isochrysis aff. galbana (T) and Pavlova lutheri (P), and two diatoms, Chaetoceros gracilis (C) or Skeletonema costatum (S), were tested as two ternary diets, namely PTC and PTS. PTC and PTS were compared with diets that also included R. salina (R). The addition of R. salina and the replacement of C. gracilis by S. costatum in the traditional hatchery diet seem to be two interesting alternatives for increasing the productivity of larval...

Autores: Barille, Laurent.
Recent feeding-physiology experiments have shown that the Japanese oyster Crassostrea gigas was able to operate a selection among inorganic and organic particles before ingestion. However, the underlying mechanisms are not well understood. Anatomical observations of different structures which may play a raie in the selection processes are brought together and submitted to the actual knowledge on bivalve feeding. The mantle lobes, the ciliary structure of the ordinary filaments, the marginal ventral groove and the labial palps are described.

Caractérisation de marqueurs génétiques fonctionnels de la nutrition et/ou de l'adaptation (les amylases) chez l'huître creuse Crassostrea gigas : intérêts pour la sélection
Provedor de dados: 5
Autores: Prudence, Marie.
Two amylase genes, A and B, from the oyster Crassostrea gigas were characterized. Using PCR-RFLP, 6 and 4 alleles, respectively, were described for the amylase genes A and B. The roles of A and B amylase genes were investigated experimentally. They are expressed during larval and adult stages, and A transcripts are more abundant than B. The A transcript increases significantly with temperature, in high trophic conditions. However, A and B transcript levels do not change when food quantity increases although amylase activity augments. The level of B is correlated with dietary starch quantities, whereas the amount of A appears to remain constant ; simultaneously amylase activity decreases and the KM increases. These results suggest that expression of B is...

Autores: Cahu, Chantal; Zambonino, Jose-luis.
The production of fish larvae by hatchery shows an intensive increase for several species, but the specific nutritional requirements of larvae were poorly known until some years. We have conducted several experiments aimed to understand the specificities in larvae digestion, and to formulate a compound diet taking into account the differences compared to juveniles. The chosen species was the European sea bass, Dicentrarchus labrax, and the data were validated on different species. Larvae were fed live preys or experimental compound diet, especially formulated for the experiment. It appeared that pancreatic digestive enzymes, such as trypsin and amylase could be assayed in early ontogenesis, before mouth opening, and increase dramatically during the first...

Deciphering the effect of food availability, growth and host condition on disease susceptibility in a marine invertebrate
Provedor de dados: 5
Autores: Pernet, Fabrice; Tamayo, David; Fuhrmann, Marine; Petton, Bruno.
Food provisioning influences disease risk and outcome in animal populations in two ways. On the one hand, unrestricted food supply improves the physiological condition of the host and lowers its susceptibility to infectious disease, reflecting a trade-off between immunity and other fitness-related functions. On the other hand, food scarcity limits the resources available to the pathogen and slows the growth and metabolism of the host on which the pathogen depends to proliferate. Here, we investigated how food availability, growth rate and energetic reserves drive the outcome of a viral disease affecting an ecologically relevant model host, the Pacific oyster, Crassostrea gigas. We selected fast- and slow-growing animals, and we exposed them to high and low...

The present study deals with technical problems encountered under lab conditions in studies of trophic relations between deposit-feeding invertebrates and microorganisms. Using 2 pure cultures of Pseudomonas and Navicula , it was shown that these microorganisms will attach to artificial (glass beads) and natural (sand grains) substrates. Best microbial attachment was observed on sand (up to 4.8 x 10 super(8) cells.g super(-1) dry wt.). The radioactive labelling of the microorganisms depends not only on the form under which the isotope ( super(14)C) is supplied to the cultures, but also on the time and the duration of the labelling. 70% of the isotope was incorporated in a stable manner by the diatoms. The bacteria incorporated, at most, 34% of the...

Autores: Leray, C.
The authors report the results of physiological and biochemical experiments which confirm the important role player by fish (Salmo gairdneri ) intestinal mucosa in their osmoregulatory process. The ability of the dietary lipids to modulate this function is described. It was demonstrated that the ionic apical permeability of the enterocytes are related to their membrane lipid composition. The importance of the essential fatty acids is emphasized. The time course changes of the apical permeability are of value in improving sea water adaptation, similar conclusions are reported for Nacl supplementation.

The aim of this study was to evaluate the performance of Patagonian octopus fed with moist diets formulated with several local feed ingredients. All formulated diets were based on crab paste (70%) and the experimental feed ingredient (30%). Experiment I assayed salmon meal, prime sardine meal, and wheat gluten, using fresh fish as a control; experiment 2 assayed prime fish meal and macroalgal meal against crab paste alone as a control. The ingestion rate was lower than expected for all diets except those of fresh fish, crab paste alone, and crab paste plus prime sardine meal. No significant differences were found in the observed digestibility of the diets, indicating, in general, low digestibility, even for fresh fish. The highest protease values were...

Définition d'un modèle d'élevage larvaire intensif pour la daurade Sparus auratus
Provedor de dados: 5
Autores: Ounais-guschemann, Nadia.
This study defines rearing parameters for mass products of 30-day old post larvae. Continuous lighting (600 lux) optimizes the predatory activity and suppresses the feeding rhythm. For 4-5 mm larvae (15 days), food ingestion slows down if the prey concentration in the tank is below 5 rotifers/ml, while there is no such threshold for 6-7 mm larvae (22 days). The rotifer Brachionus plicatilis , between 100 and 200 mu m, is an adequate initial prey, it can be replaced by Artemia salina for 7-8 mm larvae (30 days). It is observed that free amino acids and essential fatty acids contents have a prominent role in larvae growth; docosahexaenoic acid (C22:6n-3) content could be determined. Finally, the development of the swim bladder is facilitated by the renewal...

Crassostrea gigas Iarvae were collected in the bay of Arcachon in July 1985, 1986 and 1987. Larval samples were collected daily at high tide, during at least the first 12 days of pelagie lire and every hour during 1 day and night cycle, 6 days after spawming. Epifluoreseence microscopy was used for detecting ingestion and digestion of nanoplankton and thin sections were made to try to determine the algal species ingested. The first algal uptake occurred 48 hours after fertilization and different stages or digestion were noted from the 3rd day. No relationship between ingestion or digestion and the age of the viligers was observed. There was no difference in the feeding activity du ring day and night. Because the nutrition index was high (70%) the feeding...

Complex interactions between oyster, environment and pathogens were observed during the MOREST (2001-2005) project on summer mortality events of Crassostrea gigas oysters in France. The talk will show how nutrition level increasing reproductive intensity generates a risk for pathogen infection under synergistic effect of temperature and stress. Moreover, a genetic component is associated to specific reproductive performances and spawning behaviour. To better understand origin of such resistance or susceptibility to summer mortality, other characteristics as stress susceptibility, energy management and hemocyte activities of oysters from the two phenotypes were compared. This first comparison suggests interactions between stress, reproduction and defence...

Nutritional bioenergetics and estimation of waste production in non-salmonids
Provedor de dados: 5
Autores: Kaushik, Sadasivam.
The general principles behind the bioenergetic approach for predicting growth, as well as for decreasing feed and nutrient losses, have been set forth for salmonids. Given the diversification of fish farming activities around the world and the ever increasing concern for water quality management, it becomes essential to verify whether an approach developed for salmonids is applicable to other species. Given this general background, an attempt is made here to check the theoretical assumptions and technical considerations behind the bioenergetic principles developed for rainbow trout with other freshwater or marine species. From a conceptual point of view, recent literature data do indicate that as far as nitrogen or energy balance is concerned, the general...

Respiration, excretion (NH4 and PO4) and feeding of zooplankton from the upper 200 m of the Almeria-Oran frontal region (western Mediterranean), were studied during winter 1997. Eight sites belonging to the three main hydrodynamic structures of the area (Mediterranean water, geostrophic Atlantic jet and associated anticyclonic gyre) were considered. Lowest values of respiration, PO4 excretion, O/P atomic ratio and particle ingestion were found in Mediterranean waters. At the frontal limit, respiration and ammonium excretion were enhanced compared to the adjacent structures (Mediterranean water and Atlantic jet). In the gyre water, lowest O/N and highest N/P values were observed and maximum faecal pellet production and reproduction activity (inferred from...

Role of bacteria in the gastral cavity of Anthozoa.
Provedor de dados: 5
Autores: Herndl, G; Velimirov, B.
Bacterial density of the coelenteric fluid (CF) of some anthozoan species was determined in situ and under laboratory conditions. In all species examined bacterial density of the CF was higher in the gastral cavity than in ambient ranging from 10 super(5) up to 5 x 10 super(6) cells. ml super(-1). Incubation experiments with the CF indicate that a bacterial population within the coelenteron is efficiently controlled by the CF, favoring bacterial growth if bacterial densities are low in the CF and showing clearance activity at high bacterial densities. Feeding of pre-starved anthozoans caused a rapid response of coelenteric rod-shaped bacteria. Evidence is presented that coelenteric bacteria are digested periodically although they contribute 1% to the...

Essais d'amélioration de la qualité des huîtres creuses, Crassostrea gigas, en milieu naturel (claires)
Provedor de dados: 5
Autores: Gras, Marie-paule; Gras, Paul.
Depuis l'extension de la culture de Crassostrea gigas, la qualité de ces huîtres creuses apparaît très variable au moment de leur commercialisation en fin d'année. En vue d'essayer d'améliorer la qualité de ces bivalves, nous nous sommes efforcés de comparer simultanément l'influence de différents apports nutritifs sur des huîtres provenant d'un lot homogène, mises à l'affinage en claires : bassins creusés dans des terrains plats et argileux, dont l'alimentation en eau de mer se fait à certains coefficients de marée. Les anciens marais-salants de la région de Marennes-Oléron, aujourd'hui presque tous désaffectés, ont été pour la plupart transformés en claires à huîtres

L'absorption intestinale des lipides chez la truite arc-en-ciel (Salmo gairdneri )
Provedor de dados: 5
Autores: Vernier, J; Sire, M.
Though the absorption of dietary lipids is much slower in S. gairdneri than in mammals, the mechanism does not differ fundamentally. The long chain fatty acids resulting from intraluminal hydrolysis are esterified by the epithelial cells and transferred as VLDL-like particles and chylomicrons to lymph. The size of granules depends on the nature of the ingested fatty acids. The intracellular stages of this lipoprotein synthesis are defined.

Evaluation du probiotique bactérien Pediococcus acidilactici MA18/5M chez la crevette pénéide Litopenaeus stylirostris en Nouvelle- Calédonie
Provedor de dados: 5
Autores: Castex, Mathieu.
P. acidilactici MA 18/5M is a dietary probiotic (BACTOCELL®) which has shown its efficiency on several terrestrial and aquatic species. The present thesis aimed to investigate more fully the effects of this probiotic on cultured penaeid shrimps. For this study, we chose a global approach by replacing the problem studied in a model of interactions between three compartments: the shrimp, its intestinal microflora and the probiotic. Having first defined how the probiotic should be administrated, we studied its effects under controlled laboratory conditions at several levels of Litopenaeus stylirostris biology: (i) Nutritional status and growth, (ii) associated bacterial microflora, and (iii) health status with respect to oxidative stress. Then the probiotic...

Does broodstock nutritional history affect the response of progeny to different first-feeding diets? A whole-body transcriptomic study of rainbow trout alevins
Provedor de dados: 5
Autores: Lazzarotto, Viviana; Corraze, Genevieve; Larroquet, Laurence; Mazurais, David; Medale, Francoise.
The whole-body transcriptome of trout alevins was characterised to investigate the effects of long-term feeding of rainbow trout broodstock females a diet free of fishmeal and fish oil on the metabolic capacities of progeny. Effects were studied before first feeding and after 3 weeks of feeding diets containing different proportions of marine and plant ingredients. Feeding alevins plant-based diets resulted in lower fish body weight, irrespective of maternal nutritional history. No differences in whole-body lipids were found between treatments, and the tissue fatty acid profile strongly reflected that of the respective broodstock or first-feeding diets. We showed that the maternal diet history did not significantly affect expressions of any genes before...

Lifecycle Ecology of Deep-Sea Chemosymbiotic Mussels: A Review
Provedor de dados: 5
Autores: Laming, Sven; Gaudron, Sylvie M.; Duperron, Sebastien.
Mussels within the subfamily Bathymodiolinae, in particular the larger Bathymodiolus species (sensu lato) thriving at cold seeps and hydrothermal vents, are among the most iconic fauna to colonize deep-sea reducing habitats globally. Fuelled by energy derived from chemosynthetic symbioses, their contribution to ecosystem productivity is conspicuous, with many bathymodioline species forming dense, extensive aggregates. Chemosymbiotic mussels play crucial roles as ecosystem engineers, both through the formation of spatially heterogeneous biogenic reefs and in redistributing reduced-fluid emissions. The notable absence of Bathymodiolinae outside of reducing ecosystems affirms their dependency on these ephemeral habitats, placing spatiotemporal constraints on...

The impact of diets upon the fatty acid composition of haemocyte polar lipids and consequently upon immune parameters has been tested in the oyster Crassostrea gigas and the clam Ruditapes philippinarum. Oysters and clams were fed each of three cultured algae: Chaetoceros calcitrans, which is rich in 20:5(n-3) and 20:4(n-6) and poor in 22:6(n-3) fatty acids; T-Iso (Isochrysis sp.), which is rich in 22:6(n-3) and deficient in 20:5(n-3) and 20:4(n-6); and Tetraselmis suecica, which is deficient in 22:6(n-3) and contains only small amounts of 20:5(n-3) and 20:4(n-6). Fatty acid composition of haemocyte polar lipids was greatly affected by the diet. Oysters and clams fed C. calcitrans maintained a higher proportion of 20:5(n-3) and 20:4(n-6) in their haemocyte...

Autores: Al-lihaibi, Ss; Al-sofyani, Aa; Niaz, Gr.
Three species of corals Stylophora pistillata, Lobophyllia corymbosa and Echinopora gemmacea were collected from Sharm Obhur to study their chemical composition. This information was important in the investigation of their metabolic pathways and their mode of feeding. The concentrations of amino acids in these species were 9.37, 21.35 and 3.09 mg.g(-1) dry weight of coral respectively. Plant pigments were highest in E. gemmacea followed by S. pistillata and then by L. corymbosa. Lipid concentrations in S. pistillata, L. corymbosa and E. gemmacea were 1.90, 8.58 and 1.32 mg.g(-1) of total coral respectively. The fatty acid methyl esters were analyzed in these species and the most abundant saturated acids were 16:0 and 18:0, while unsaturated acids included...

Autores: Berland, Brigitte R; Maestrini, Serge Y; Grzebyk, Daniel; Thomas, Pierre.
No species of Dinophysis has yet been cultured in the full sense. To determine the photosynthetic capability in D. cf. acuminata, the dominant morphotype of the genus along the French Atlantic coast, we took material from natural populations, in some trials by pipetting out single cells, and in others using plankton assemblages enriched in D. cf, acuminata by size fractionation and reverse sedimentation. Inorganic carbon uptake was measured at temperatures from 11 to 23 degrees C and at a light intensity of 400 mu mol photons m(-2) s(-1). Total uptake was proportional to the number of cells and increased linearly with incubation time, the uptake rate showing a distinct maximum at 18 degrees C, while at 23 degrees C being only half this maximum....

Impact of 20 : 4n-6 supplementation on the fatty acid composition and hemocyte parameters of the Pacific oyster Crassostrea gigas
Provedor de dados: 5
Autores: Delaporte, Maryse; Soudant, Philippe; Moal, Jeanne; Giudicelli, Emilie; Lambert, Christophe; Seguineau, Catherine; Samain, Jean-francois.
Arachidonic acid (20:4n-6, ArA) and its eicosanoid metabolites have been demonstrated to be implicated in immune functions of vertebrates, fish, and insects. Thus, the aim of this study was to assess the impact of ArA supplementation on the FA composition and hemocyte parameters of oysters Crassostrea gigas. Oyster dietary conditioning consisted of direct addition of ArA solutions at a dose of 0, 0.25, or 0.41 mu g ArA per mL of seawater into tanks in the presence or absence of T-Iso algae. Results showed significant incorporation of ArA into gill polar lipids when administered with algae (up to 19.7%) or without algae (up to 12.1%). ArA supplementation led to an increase in hemocyte numbers, phagocytosis, and production of reactive oxygen species by...

Fatty acids from lipids of marine organisms: Molecular biodiversity, roles as biomarkers, biologically active compounds, and economical aspects
Provedor de dados: 5
Autores: Berge, Jean-pascal; Barnathan, Gilles.
Because of their characteristic living environments, marine organisms produce a variety of lipids. Fatty acids constitute the essential part of triglycerides and wax esters, which are the major components of fats and oils. Nevertheless, phospholipids and glycolipids have considerable importance and will be taken into account, especially the latter compounds that excite increasing interest regarding their promising biological activities. Thus, in addition to the major polyunsaturated fatty acids (PUFA) such as eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids, a great number of various fatty acids occur in marine organisms, e.g. saturated, mono- and diunsaturated, branched, halogenated, hydroxylated, methoxylated, non-methylene-interrupted.

Physiology and continuous culture of the hyperthermophilic deep-sea vent archaeon Pyrococcus abyssi ST549
Provedor de dados: 5
Autores: Godfroy, Anne; Raven, N; Sharp, R.
The deep-sea vent archaeon Pyrococcus abyssi strain ST549 was grown in batch cultures in closed bottles and by continuous culture in a gas-lift bioreactor, both in the presence and in the absence of elemental sulfur. Growth on carbohydrates, proteinaceous substrates and amino acids was investigated. The disaccharides maltose and cellobiose were shown not to be able to enhance growth suggesting that P. abyssi ST549 is unable to use them as carbon sources. By contrast, proteinaceous substrates such as peptone and brain heart infusion were shown to be very good substrates for the growth of P. abyssi ST549 and allowed growth at high steady-state cell densities in continuous culture. Growth on brain heart infusion was shown to require additional nutrients when...

It is feasible to think that the body composition assessment may be influenced by maturational and zinc status, especially in young athletes, which perform regularly high volume of physical training. In accordance, it seems important to clarify the impact of these factors in body composition assessment in athletes, since errors may lead to mistakes in training prescription and diet elaboration, and therefore affect the athletic performance. The objective was to compare (1) different methods of body composition evaluation in young soccer players stratified by zinc plasma levels; and (2) the two reference methods using skinfolds thickness in children (Slaughter's and Lohman's equations), considering the maturation level. In this cross-sectional study, fifty...

Autores: Trindade,E. B. S. M.; Souza,L. R.; Lopes,C. A. M.; Pereira,P. C. M.
The intestinal microbiota consists of a qualitatively and quantitatively diverse range of microorganisms dynamically interacting with the host. It is remarkably stable with regard to the presence of microorganisms and their roles which, however, can be altered due to pathological conditions, diet composition, gastrointestinal disturbances and/or drug ingestion. The present review aimed at contributing to the discussion about changes in the intestinal microbiota due to HIV-1 infection, focusing on the triad infection-microbiota-nutrition as factors that promote intestinal bacterial imbalance. Intestinal microbiota alterations can be due to the HIV-1 infection as a primary factor or the pharmacotherapy employed, or they can be one of the consequences of the...

Interaction between infection, nutrition and immunity in tropical medicine
Provedor de dados: 80
Autores: Pereira,P. C. M.
Host nutritional state has an important role in susceptibility to bacteria, parasites, and viral infections. Infection precipitates the appearance of signs and symptoms of nutrition deficiencies in the undernourished; this can aggravate infection evolution. Infection stimulates specific and non-specific host defense mechanisms; these are directly influenced by the nutritional state of micro- and macronutrients. Immune alterations, which are closely related to nutritional status, markedly contribute to a higher susceptibility to infectious agents and can also contribute to worsening nutritional state, forming a vicious cycle.

Tooth wear can affect body condition, reproductive success and life expectancy. Poor dental health is frequently reported in the zoo literature, and abrasion-dominated tooth wear, which is typical for grazers, has been reported in captive browsing ruminants. The aim of this study was to test if a similar effect is evident in captive rhinoceros species. Dental casts of maxillary cheek teeth of museum specimens of captive black (Diceros bicornis; browser), greater one-horned (Rhinoceros unicornis; intermediate feeder) and white rhinoceroses (Ceratotherium simum; grazer) were analysed using the recently developed extended mesowear method for rhinoceroses. Captive D. bicornis exhibited significantly more abrasion-dominated tooth wear than their free-ranging...

The effects of protein intake on two adult male and female populations of Ceratitis capitata Wiedemann were assessed. One population consisted of flies reared for twenty years in the laboratory (Lab-pop); the other population consisted both of flies reared in the laboratory for approximately fifteen years and of the periodically introduced wild flies (Hybrid-pop). Three diets were tested: a no-yeast diet and two diets containing yeast (protein source) at the concentrations 6.5 g or 1.5 g per 100 ml diet. The parameters analyzed were: adult longevity, diet intake with and without yeast, and discrimination threshold for yeast. Protein intake increased Lab-pop adult longevity and did not affect longevity of the Hybrid-pop. Longevity in each population was...

Five completely randomized experiments with 3 replicates per treatment were conducted. Juveniles (0.2-0.5 g) from the experimental farm were used. Trials were conducted at the Centro de Obtención y Cría de Larvas de Santa Cruz del Sur, Camaguey, and the Complejo Camaronero de Tunas de Zaza, Sancti Spiritus. In the first trial, 40-l plastic experimental units with 10 shrimp/unit were used to test the response of L. schmitti to the partial and total substitution (46, 59, 75, 88 y 100%) of...

Hábitos alimentarios y comportamiento trófico del caballito de mar (Hippocampus sp) en la bahía de San Antonio (Río Negro)
Provedor de dados: 20
Autores: Storero, L.P.
Los caballitos de mar, Hippocampus sp. (Syngnathidae), presentan rasgos característicos: escasa flexibilidad, natación lenta y hábitos sedentarios. Por otra parte, en la bahía San Antonio (Río Negro, Patagonia), el ambiente en el que viven presenta corrientes intensas, amplio rango de fluctuación térmica y variaciones en la disponibilidad de alimento. Estas características ambientales limitarían la capacidad de desplazamiento y predación de la especie, forzando a la adopción de una estrategia alimentaria de tipo oportunista. Los objetivos del presente estudio fueron determinar la composición de la dieta del caballito de mar (Hippocampus sp.) en la bahía San Antonio a partir de contenidos estomacales e intestinales, y evaluar el comportamiento alimentario...

Autores: Alvarez, J.S.; Hernandez-Llamas, A.; Galindo, J.; Fraga, I.; Garcia, T.; Villareal, H.
The feasibility of substituting soybean meal for ¢shmeal diets for juvenile white shrimp Litopenaeus schmitti (0.35   0.01g) was evaluated, and an adequate substitution level was determined. Five diets were evaluated using 46%, 59%, 75%, 88% and 100% substitution levels. Pellet water stability was signi¢cantly a¡ected by dietary soybean content (Po0.05). Increased soybean content produced lower pellet stability, ranging from a dry matter loss of 14^ 22% after a 2-h immersion, and 20^33% after an 8-h immersion. After 52 days, signi¢cant di¡erences (Po0.05) were found in shrimp weight, feed conversion ratio and protein e⁄ciency ratio. The values were 0.64^1.06 g, 2.8^7.9 and 0.45^1.21, respectively, for the three measurements. Overall, better results were...

L’allache ou sardinelle ronde (Sardinella aurita, Valenciennes, 1847) est une espèce de la famille des Clupeidae à affinité intertropicale. Cette espèce est la plus représentée dans les produits de la pêche en Tunisie. Dans cette étude on a évalué la qualité nutritionnelle de ce poisson en évaluant sa richesse en oligo-éléments et en acides gras. Pour ce fait, on a suivi les concentrations saisonnières de ces éléments dans quatre organes dont certains sont les plus consommés à savoir la chair et les gonades. Par contre, d’autres sont facultativement consommés par les habitants de certaines régions de la Tunisie notamment le cerveau et le foie. Les échantillons de la sardinelle ont été collectés mensuellement auprès des embarcations professionnelles...

Autores: Ayinla, O.A.; Bekibele, D.O.
The fish feed and nutrition in Nigeria was reviewed. Crab meal, shrimp head meal, tadpole meal, soybean meal were used for partial or total replacement of fish meal in the diets of cultivable fish species and no satisfactory result is yet obtained for 100% of replacement of fishmeal.  The cost price of species specific diets so far developed is out of tune for profitable fish farming venture. Further investigation is required to develop cost effective species specific diets. The problem in feed and nutrition was highlighted and possible solutions were proffered.

The Demand for Food Away from Home: Do Other Preferences Compete with Our Desire to Eat Healthfully?
Provedor de dados: 31
Autores: Stewart,   Hayden; Blisard,   Noel; Jolliffe,   Dean; Bhuyan,   Sanjib.
Health-oriented government agencies have had limited success at encouraging Americans to eat a healthful diet. One reason may be that other preferences compete with our desire to eat healthfully. We explore the effect of consumer preferences on the demand for food away from home, including frequency of eating out and choice of outlet type. Preferences for convenience and ambience are found to influence behavior. Furthermore, omitting these variables from econometric models can bias the estimated effect of preferences for a healthful diet.

Dietary Effects of Menu Choices in the National School Lunch Program
Provedor de dados: 31
Autores: Ishdorj,   Ariun; Crepinsek,   Mary Kay; Jensen,   Helen H.
Childhood and adolescence are unique periods of growth and development. In addition to maturing physically, children begin to make independent choices about when, where, and what they eat. Good nutrition during childhood and adolescence plays a key role in assuring adequate growth and development, preventing the long-term risk of chronic disease, and enhancing health and well-being. The U.S. Department of Agriculture’s (USDA) school meal programs play an important role in children’s diets and can thus influence their weight status and health. On average, children obtain more than one third of their daily energy intake from meals consumed at school during the school year (Briefel et al 2009). The National School Lunch Program (NSLP) is one of the largest...

Fat Chance: Modelling the Socio-Economic Determinants of Dietary Fat Intake in China
Provedor de dados: 31
Autores: Shankar,   Bhavani.
Quantile Regression methods have much to offer the investigation of the determinants of dietary intake. Dietary inadequacy or excess occurs at the tails of nutrient and food intakes, and it seems intuitive that intake responses in these areas will differ from elsewhere along the intake distribution. We apply quantile regression to examine the drivers of a key aspect of dietary health, fat density of energy intake in China. The sample of 2612 individuals between the ages of 20 and 45 is derived from the China Health and Nutrition Survey. The following insights emerge: (i) Fat density increases with income, but worryingly the income effect is more pronounced at the upper conditional tail of fat intake (ii) While it is confirmed that an urban location...

New Evidence on Overweight Children in Urban China and the Role of Socioeconomic Factors
Provedor de dados: 31
Autores: Dong,   Fengxia; Jensen,   Helen H.
Problems of overweight and obesity among children have increased in China and pose a problem both for individuals as well as for public social and health care systems. This study explores factors contributing to weight problems among children age 6 to 18 years old in urban China. Data come from the 2004 China Health and Nutrition Survey. Results from a binary probit model show that parents' being overweight, some patterns of TV use, and more frequent eating in fast food restaurants influence children being overweight. Among younger children, parent's dietary knowledge was a significant factor. For adolescents, TV habits and concern about being liked by friends were significant. The results suggest that targeted nutrition education, especially for parents...

The Prevalence of Under-Nourished Child Obese Mother Phenomenon in Rural Areas: Evidence from Central Province of Kenya
Provedor de dados: 31
Autores: Mburu,   John G.; Okello,   Julius Juma.
Attainment of nutritional security is a major focus of the Millennium Development Goals. Despite efforts, Sub-Saharan Africa countries are yet to make significant progress in becoming nutritionally secure. Over the years, maternal obesity and child under-nutrition have concurrently been on the increase. The rise in obesity and child under-nutrition is attributed to, among others, urbanization-driven shifts in eating habits and lifestyle, changes in purchasing power, food assistance and stress-related medical conditions.  Studies in Asia and Latin America have associated co-existence of adult obesity and child under-nutrition with urban areas. In this paper we examine the prevalence of child under-nutrition and mother obesity in rural Kenya. We find that 22...

Economic Potential for Nutritional Improvement in Feed Grains
Provedor de dados: 31
Autores: Brennan,   John P.; Singh,   Rajinder Pal; Bialowas,   Adam.
Feed grains researchers have abundant technical opportunities to select various options for improvement of nutritional characteristics of feed grains. Choosing between those opportunities is a difficult issue for research funding organisations. In this paper, efforts to address the relative economic benefits from the different options for feed grains nutritional improvement are reported. The economic benefits arising from nutritional improvements in various feed grains are examined and compared to the benefits from increasing yields of the feed grains rather than improving their nutritional value. The results of the analysis of these options are presented in an economic surplus framework that enables the major beneficiaries and the relative gains for the...

CATTLE ON FEED EVALUATION, PART I: FEEDLOT MANAGEMENT PRACTICES
Provedor de dados: 31
Autores: Dargatz,   David.
The NAHMS Cattle on Feed Evaluation (COFE) was designed to provide both participants and the industry with information on the nation's feedlot animal population for education and research.  The USDA's National Agricultural Statistics Service (NASS) collaborated with NAHMS to select a statistically valid producer sample (3,214 producers) to provide inferences to the nation's feedlot animal population.  Included in the study were 13 states that accounted for 85.8 percent of the U.S. cattle-on-feed inventory as of January 1, 1994.  NASS telephone interviewers contacted a total of 3,214 producers by telephone or personal interview from August 1 through September 16, 1994 for Part I.   Contact for this paper: David Dargatz

A REVIEW OF FOOD SECURITY AND HUMAN NUTRITION ISSUES IN NEPAL
Provedor de dados: 31
Autores: Shively,   Gerald E.; Gars,   Jared; Sununtnasuk,   Celeste.
Nepal faces multiple development challenges, including chronic and widespread food insecurity and adult and child malnutrition. Due to population growth, agricultural stagnation and a range of institutional failures, the threat of a serious food crisis in Nepal is substantial. The recent scaling back of WFP assistance means that food security conditions in some parts of Nepal will undoubtedly worsen in the near future. This paper presents a brief review of topics and available evidence regarding food security, malnutrition and related subjects in Nepal. It is intended to document important source material and provide an overview of topics for non-specialists or those moving into new areas of concern.

The Effect of Retail Grocery Coupons for Breakfast Cereals on Household Purchasing Behavior
Provedor de dados: 31
Autores: Berning,   Joshua P.; Zheng,   Hualu.
We examine the affect of retail and manufacturer coupons on the nutritional quality of breakfast cereal purchases made by households. Using household level purchase data we find that coupon usage has a significant impact on the nutritional quality of cereals purchased by households. Specifically, we find that the average sugar content decreases and the fiber content increases. This suggests that coupons have a positive impact on the nutritional quality of cereals purchased by households, holding all other factors constant.   Given the prolific use of coupons by households and the fact that they offer both a price discount and an advertisement for products, they might be an effective way to help guide consumers to healthier food choices.

The Choice of Fish Species: An Experiment Measuring the Impact of Risk and Benefit Information
Provedor de dados: 31
Autores: Marette,   Stephan; Roosen,   Jutta; Blanchemanche,   Sandrine; Verger,   Philippe.
An experiment was conducted in France to evaluate the impact of health information on consumer’s choice. Fish have positive and negative health attributes, and we focus on fish species of diverging risk-benefit ratios. Successive messages revealing risks (methylmercury) and benefits (omega-3s), along with consumption recommendations, were delivered to experiment participants. Results show significant differences in reaction among participants depending on the sequencing order of information on risks and benefits. The results of the experiment are combined with a partial equilibrium model to determine the value of information. Acknowledging adjustments of equilibrium prices, health information is shown to have significant value to consumers.

DETERMINANTS OF FOOD AWAY FROM HOME AMONG AFRICAN-AMERICANS
Provedor de dados: 31
Autores: Pert,   Calvert; Bhuyan,   Sanjib.
The prominence of FAFH on consumers’ food expenditure raises some important questions, particularly those related to the health impact of such a trend. This is particularly true among African-Americans because on average African Americans are twice as likely as white Americans to develop Type 2 diabetes, which has been known to have some correlation with one’s diet.  There is a plethora of studies focusing on FAFH by American consumers.  However, there are very few studies that focus exclusively on African-Americans. This study tries to fill that gap.

What Influences Tastes? An Analysis of the Determinants of Consumers’ Demand for Tastes in Food
Provedor de dados: 31
Autores: Drichoutis,   Andreas C.; Lazaridis,   Panagiotis.
This article explores the factors affecting demand for tastes in food. Following Silberberg (1985) we divide demand for food into demand for nutrition and demand for  tastes. We first compute the minimum cost required to fulfil the Recommended Daily  Allowances (RDAs) of households and attribute the difference of minimum cost from actual expenditures as the expenditure for tastes. Since prices are essential in deriving the minimum cost and data do not allow for the derivation of prices for food consumed away-from-home (FAFH), we also present a way to account for the FAFH expenditure. Data from the 1998/99 Greek Household Expenditure Survey are used. Results indicate a number of socioeconomic factors such as income, household size, urbanization, age and...

Autores: Kennedy,   Eileen T.; Cogill,   Bruce.
The commercialization of Agriculture is the cornerstone on economic development in the most developing countries. Yet relatively little is known about the income and nutritional effects of increasing commercial Agriculture. The present study by Eileen Kennedy and Bruce Cogill is the first in a series of studies conducted by IFPRI in Africa, Asia, and Central America to assess the effects of the commercialization of Agriculture on production, consumption, and nutrition status.  In 1983 IFPRI was invited by the government of Kenya to undertake a study of the production and consumption effects of a smallholder sugarcane contracting scheme in Southwestern Kenya. The resulting study is unusual because it uses a random sample of farmers at various stages of...

Can Qualitative and Quantitative Methods Serve Complementary Purposes for Policy Research?: Evidence from Accra
Provedor de dados: 31
Autores: Maxwell,   Daniel G.
Qualitative and quantitative methods in social science research have long been separate spheres with little overlap. However, recent innovations have highlighted the complementarity of qualitative and quantitative approaches. The Accra Food and Nutrition Security Study was designed to incorporate the participation of a variety of constituencies in the research, and to rely on a variety of approaches—both qualitative and quantitative—to data collection and analysis. This paper reviews the way in which qualitative and quantitative methods were used in the Accra study. The argument of the paper is that the complementary use of qualitative and quantitative approaches provides a greater range of insights and perspectives and permits triangulation or the...

The rapid expansion of the population age 60 and older has a number of economic implications. The people in this group, about 18 percent of the population, account for about 30 percent of all health care expenditures. They use hospitals at nearly three times the rate of younger persons, average seven to eight medical visits per year, and occupy the majority of nursing residence beds. Providing information on the relationship of socio-economic and other factors to nutrient intake is basic to improving the health and well-being of the elderly. This exploratory investigation provides estimates of the effects of selected characteristics of the household and its constituents on individual nutrient consumption of elderly heads of households.

The impact of smallholder commercialisation on food consumption patterns in a rural community of South Africa was investigated. The consumption patterns, dietary diversity and nutrient intakes of certified and partially certified members of an organic farmers' organisation were compared to data from a random sample of non-member households. Two consecutive survey rounds (n = 200) conducted in November 2004 and March 2005 enabled comparison of dietary diversity, nutrient adequacy (in terms of per household adult female equivalents for energy, iron, and vitamin A) and expenditure elasticities between seasons. Households with members engaged in certified comm ercial organic farming enjoyed greater dietary diversity, improved nutrient intakes com pared to...

Intra-Household Allocation and Consumption of WIC-Approved Foods: A Bayesian Approach
Provedor de dados: 31
Autores: Ishdorj,   Ariun; Jensen,   Helen H.; Tobias,   Justin.
WIC, the Special Supplemental Nutrition Program for Women, Infants, and Children, is a widely studied public food assistance program that aims to provide foods, nutrition education and other services to at-risk, low-income children and pregnant, breastfeeding and postpartum women. From a policy perspective, it is of interest to assess the efficacy of the WIC program - how much, if at all, does the program improve the nutritional outcomes of WIC families? In this paper we address two important issues related to the WIC program that have not been extensively addressed in the past. First, although the WIC program is primarily devised with the intent of improving the nutrition of "target" children and mothers, it is possible that WIC may also change the...

Obesity related health problems are a potentially significant cost to Fiji. The factors driving the trend towards increased obesity are analysed. The potential for reducing the rate of increase in obesity by influincing individual food choice decisions is evaluated and a policy framework is developed for considering this issue. The analysis points to some tentative policy recommendations for food policy in fiji. The role of a systems perspective on the policy problem is highlighted and specific attention is focused on the role of a nutrient based food tax in a wider nutrition-health policy system.

Asymmetric Intra-household Allocation of Calories in China: Implication for Demographic Bias and the Need for Demographic Targeting
Provedor de dados: 31
Autores: Shimokawa,   Satoru.
This article questions the assumption of symmetric consumption behavior in the conventional analysis of intra-household calorie allocation. It proposes a framework that takes into account asymmetric consumption behavior due to liquidity constraints or loss aversion. Using panel data from China, we find that intra-household calorie allocation responds asymmetrically to expected declines and increases in household food availability, which is qualitatively consistent with the liquidity constraint model. Clarifying such asymmetric responses enables us to relate calorie elasticity estimates to the status of demographic groups within a household without requiring a full interpretation of the ordering of the estimates across demographic groups. Results also show...

Many developing regions have excellent potential agricultural resources. However, historically population has become so concentrated on such small holdings that acute poverty and malnutrition now predominate. The food scientists’ response to the chronic nutritional problem has often been subsidized bio-fortification with nutritional supplements or more recently cultivars with higher nutrient levels. Where much of the population is in this inadequate nutrition category as in highland Ethiopia, the supplements are neither financially feasible nor sustainable. The cultivars can provide a few critical nutrients but are not a comprehensive solution. To improve nutrition, it is necessary to increase income so that an increased quality and quantitative diet can...

Poor child health and nutrition persist throughout West Africa.  This research analyzes the impact of key economic variables, including income, education and background characteristics, on child health and nutrition across nine different countries.  The results are interpreted in the context of differing levels of economic development among these nations.  The findings do not show wealth and parental education to be robust across the sample, but maternal background characteristics have a positive, statistically significant and highly consistent effect across all the countries.  The importance of mothers' height does not simply represent a genetic influence, but can be interpreted to signify that women with a healthier upbringing, and hence taller, have...

The Changing Food Assistance Landscape: The Food Stamp Program in a Post-Welfare Reform Environment
Provedor de dados: 31
Autores: Gundersen,   Craig; LeBlanc,   Michael; Kuhn,   Betsey A.
The Personal Responsibility and Work Opportunity Reconciliation Act of 1996 (PRWORA) dramatically transformed and continues to transform the food assistance landscape in the United States. The Act cut more funds from the Food Stamp Program than it did from any other program, through reductions in benefits per person and restrictions in eligibility. Despite these cuts, food stamps now have a more prominent role in the post-welfare reform social safety net because the largest cash-assistance entitlement program, Aid to Families with Dependent Children (AFDC), was replaced with the Temporary Assistance to Needy Families (TANF) program, a nonentitlement program. This leaves the Food Stamp Program as one of the only remaining entitlement programs available to...

U.S. Demand for Food and Nutrition in the 20th Century
Provedor de dados: 31
Autores: Beatty,   Timothy K.M.; LaFrance,   Jeffrey T.
A great deal of research on farm and food policy and consumer choice focuses on the link between food consumption and nutrition. This paper presents and applies a new method to analyze the demand for food and nutrients, and consumer welfare. The foundation for this method is the recent extension of the Gorman class of exactly aggregable demand models to incomplete demand systems. The purposes of this approach are to derive and implement coherent, flexible empirical models of food and nutrient demand, to estimate the model parameters consistently with aggregate data, and to make inferences on the impacts of farm and food policy changes on food and nutrient demand and consumer welfare of those policies. We apply this framework to annual per capita U.S....

Meeting Total Fat Requirements for School Lunches:  Influences of School Policies and Characteristics
Provedor de dados: 31
Autores: Newman,   Constance; Guthrie,   Joanne F.; Mancino,   Lisa; Ralston,   Katherine L.; Musiker,   Melissa.
Concerns about child obesity have raised questions about the quality of meals served in the National School Lunch Program. Local, State, and Federal policymakers responded to these concerns beginning in the mid-1990s by instituting a range of policies and standards to improve the quality of U.S. Department of Agriculture-subsidized meals. Schools have been successful in meeting USDA nutrient standards except those for total fat and saturated fat. This report uses school-level data from the School Nutrition Dietary Assessment-III to calculate statistical differences between the fat content of NSLP lunches served by schools with different policies (e.g., menu planning) and characteristics like region and size. Positive associations are found between a meal’s...

Food Security and Nutrition in Bangladesh: Progress and Determinants
Provedor de dados: 31
Autores: Hossain,   Mahabub; Naher,   Firdousi; Shahabuddin,   Quazi.
For Bangladesh food security was synonymous with achieving self-sufficiency in rice production and stabilization in rice prices. The country has made good progress in increasing rice production through technological progress, facilitated by private sector investment in small scale irrigation. But, it is difficult to sustain the progress made in view of the growing pressure of population on scarce land resources. Domestic food grain production remains susceptible to floods and droughts thereby perpetuating the threat of major production shortfalls, inadequate food availability, and vulnerability from fluctuation in prices. The availability of other foods has not increased, and the progress in nutritional outcome has remained slow. Forty percent of the...

The Supplemental Nutrition Assistance Program, Financial Stress, and Childhood Obesity
Provedor de dados: 31
Autores: Burgstahler,   Rebecca; Gundersen,   Craig; Garasky,   Steven B.
The Supplemental Nutrition Assistance Program (SNAP) is the largest nutritional assistance program addressing food insecurity in the United States. Due to the program’s reach, SNAP has been called upon to address other nutrition-related challenges facing low-income Americans, including childhood obesity. This study considers the effect of SNAP participation on child weight outcomes after controlling for household financial stress, an important determinant of child overweight status that disproportionately affects low-income households. Using data from the Survey of Household Finances and Childhood Obesity and instrumental variable methods, we find that SNAP participation is negatively associated with obesity among eligible children.

Do Income Constraints Inhibit Spending on Fruits and Vegetables Among Low-Income Households?
Provedor de dados: 31
Autores: Stewart,   Hayden; Blisard,   Noel; Jolliffe,   Dean.
This study assesses whether income constraints inhibit spending on fruits and vegetables among low-income households. If this is the case, then it is hypothesized that the distribution of expenditures on fruits and vegetables by low-income households should be stochastically dominated by the distribution of expenditures on these same food items by other households. Moreover, it must be the case that low-income households would increase their spending on fruits and vegetables in response to an increase in their income. Using household data from the 2000 Consumer Expenditure Survey, a test of stochastic dominance is performed. Censored quantile regressions are also estimated at selected points of the conditional expenditure distribution. Low income...

AN ECONOMETRIC MODEL OF THE DEMAND FOR FOOD AND NUTRITION
Provedor de dados: 31
Autores: LaFrance,   Jeffrey T.
A flexible, full rank two model of food consumption that is globally consistent with economic theory, aggregates across income, demographic variables, and variations in micro demand parameters, and accommodates tradeoffs between tastes and nutrition is derived.  The econometric demand model is estimated with per capita U.S. consumption of 21 foods on the time period 1919-1994, excluding the World War II years 1942-1946.  An approach for inferring the percentage of nutrients available from individual commodities in the U.S. food supply is derived and implemented empirically on the time period 1949-1995 for the nutrients energy, protein, total fat, carbohydrates, and cholesterol.  The two sets of model results are combined to generate time paths for income...

Nutrient Demand Elasticities with Noisy Measures of Household Resources
Provedor de dados: 31
Autores: Gibson,   John.
Many studies suggest that changes in household economic resources (incomes and expenditure) have little effect on nutrient intakes and child malnutrition in developing countries. This paper examines the impact that errors-in-variables have on inferences about the importance of household incomes to the calorie and protein demands of households. Results are based on a new household survey from Papua New Guinea, with repeated observations on households during the year. These repeated observations allow regression estimates to be corrected for the differing reliabilities of the explanatory variables.

Maternal nutrition during pregnancy can have significant implications for a child’s prenatal growth and development, and undernutrition experienced during the prenatal period increases the risk of early childhood morbidity and mortality and can permanently impair a child’s physical growth and cognitive development.  We use new data from Ghana generated using contingent valuation and experimental auction techniques to estimate willingness-to-pay (WTP) for LNS, a new nutrient supplement aimed at preventing maternal undernutrition during pregnancy.  We also explore the relative importance of individual and household characteristics as well as information about the long-term benefits of preventing undernutrition on WTP.  We find that WTP is positive for a...

Let's Eat Out:  Americans Weigh Taste, Convenience, and Nutrition
Provedor de dados: 31
Autores: Stewart,   Hayden; Blisard,   Noel; Jolliffe,   Dean.
Whether eating out or buying carry-out, Americans are consuming more and more of their calories from full-service and fast-food restaurant fare. The share of daily caloric intake from food purchased and/or eaten away from home increased from 18 percent to 32 percent between the late 1970s and the middle 1990s, and the away-from-home market grew to account for about half of total food expenditures in 2004, up from 34 percent in 1974. Analysis of a survey of U.S. consumers indicates that respondents want convenience and an enjoyable dining experience, but the desire for health also plays a role as does diet-health knowledge.

Estimating Plate-Lunch Demand: A Bottom-Line Assessment of the Competitive School Food Environment
Provedor de dados: 31
Autores: Pham,   Matthew V.; Roe,   Brian E.
Direct regulation of school lunch content seems an intuitive approach for improving the nutrition of many American children. However, little is known about substitution patterns in response to such efforts, particular the likelihood that children and parents will turn to competitive foods outside the control of schools such as packed lunches. To our knowledge, no previous work documents if increasing the healthfulness of school lunches leads children to leave the school lunch line for potentially less nutritious options. To address this paucity of information we estimate the demand for school lunches as a function of calories provided and entrée protein source for a single elementary school. Our results suggest a highly inelastic response to a meal’s...

Agricultural Growth, Poverty, and Nutrition in Tanzania
Provedor de dados: 31
Autores: Pauw,   Kalie; Thurlow,   James.
Rapid economic growth has failed to significantly improve poverty and nutrition outcomes in Tanzania. This raises concerns over a decoupling of growth, poverty, and nutrition. We link recent production trends to household incomes and caloric availability using a dynamic computable general equilibrium and micro-level poverty and nutrition modules. Results indicate that the structure of economic growth—not the level—is currently constraining the rate of poverty reduction in Tanzania. Agricultural growth has been driven by larger-scale farmers that are less likely to be poor. Growth has further been concentrated in crops grown in only a few regions of the country. Slow expansion of food crops and livestock also explains the weak relationship between...

Provedor de dados: 31
Autores: Mancino,   Lisa; Gregory,   Christian A.
In this study, we use a unique dataset designed by researchers at the University of Chicago and collected by Mathematica Policy Research to investigate whether there is a significant correlation between diet quality and time spent preparing food. Overall, our results indicate that, when controlling for unobserved factors that may affect both preparation time and diet quality, time spent in food preparation influences diet quality only for obese persons. However, the improvements in diet quality are minimal. Our results also indicate that foods eaten away from home play an important role in understanding the effects of time spent in food preparation on food away from home.

Modelling physical quantities of food and nutrients consumed from aggregate data – with an application to Finland
Provedor de dados: 31
Autores: Irz,   Xavier T.
Anticipating the impact of changes in economic incentives on dietary quality and nutritional health requires knowledge of how physical quantities of food consumed respond to price and income variations. A problem arises, however, because physical quantities are: 1- not consistent aggregates in demand models; and 2- not measured at final/retail level in national statistics. The paper develops a solution by establishing explicitly the theoretical link between composite demand and physical quantities, from which a novel empirical approach to the estimation of nutrient elasticities is derived. It is applied to Finnish aggregate data from the National Accounts and Food Balance Sheets over the 1975-2006 period, and the results are used to assess the potential...

Researchers have abundant technical opportunities to select various options for improvement of nutritional characteristics of feed grains. Choosing between those opportunities is a difficult issue for research funding organisations. In this paper, an attempt to address those research resource allocation issues is reported. The approach to use in analysing improvements in the feed quality of grains is discussed. By defining the problem as a cost reduction for the livestock industries, the impact of improvements in grain nutrition can be defined by their impact on the least-cost feed rations for different livestock categories. Using that approach, the benefits of improved feeds can be evaluated, and research priorities can be determined on the basis of which...

The interest of this study is the tradeoff between nutrition and taste in consumer food choice.  We examine choice between more and less healthy versions of particular foods within four important grocery categories: breakfast cereal, milk, bread, and soft drinks.  Within a category, products do not greatly differ in terms of cost and convenience, and nutritional differences are easily determined.  Consumers are less likely to choose unhealthy foods due to cost or convenience advantages, or through ignorance. This makes the choice between taste and nutrition more apparent. We use annual expenditure data reported by a large sample of households participating in the AC Nielsen Homescan data system.  For each of the food categories we develop a measure of...

The specific objective of this paper is the investigation of the link between an improvement in Chinese households’ wealth and the quality of their diet and the role played by this relationship on the overall nutrition transition process. Better economic conditions mean a worsening of the diet in terms of higher energy intakes from fats, only partially compensated by higher fruit and vegetable intakes. China nutrition transition is going on and the rapid economic growth may lead to adverse health consequences if the negative effects of this transition will not be contrasted.

Over the past several years IFPRI has undertaken research on the production, consumption, and nutrition effects of agricultural commercialization in The Gambia, Guatemala, Kenya, the Philippines, and Rwanda. While it is widely recognized that the commercialization of agriculture is essential to overall economic development, various rural population groups adapt differently to the process of commercialization, depending on the resources available to them, economic and social conditions, and government policies. Many households benefit in the form of higher incomes; others may suffer a decline in income. A particular concern of policymakers has been the effect of commercialization on nutrition. The purpose of these studies has been to analyze the process of...

Asymmetric Response of Nutrient Intakes to Cereal Price Changes among the Poor in China: Implications for the Effect of Cereal Price Subsidies on the Poor’s Nutrient Intakes
Provedor de dados: 31
Autores: Shimokawa,   Satoru.
Previous studies commonly assume that the effects of introducing and ending cereal price subsidies on the poor’s nutrient intakes are symmetric. We question the assumption of symmetry and show that the poor’s nutrient intakes respond asymmetrically to declines and increases in the price of cereal in China. Our results imply that introducing cereal price subsidies can increase the poor’s total energy intake by increasing their calorie intakes from fat and protein, and that ending such subsidies would insignificantly affect the poor’s total energy intake; however, it may further increase their calorie intakes from fat and protein.

An Introduction to Nutrition-Agriculture Linkages
Provedor de dados: 31
Autores: Chung,   Kimberly.
Agricultural development is now expected to proceed in a way that maximizes opportunities to improve health and nutrition. Accordingly, the term “nutrition-agriculture linkages” describes the set of relationships that shows the mutual  dependence of nutrition, health and agriculture. Changes in nutrition or health status are expected to affect agricultural production; conversely changes in the agricultural sector can have significant effects on individual health and nutritional status. Most development professionals, however, are sectoral specialists. Some are trained in nutrition or agriculture, but very few will be trained in both. It is therefore difficult to begin discussions on nutrition-focused agricultural programs and policies. How do we begin to...

Optimising genetic potential for wool production and quality through maternal nutrition
Provedor de dados: 31
Autores: Hatcher,   Sue; Johnson,   P.R.
This paper reviews the development of the wool follicle population with a view to the management of breeding ewes so as to optimise the genetic potential of the progeny for wool production and quality throughout their lifetime. It highlights the importance of the pre-weaning environment (i.e. maternal nutrition through pregnancy and lactation) on the initiation and maturation of the secondary follicle population and identifies the last third of pregnancy as the most critical period. The implications of this for the commercial wool producer are discussed in terms of matching the breeding cycle of the ewes to available pasture and provision of supplementary feed. Finally, it introduces a national project 'Lifetime Wool' funded by Australian Wool Innovation...

Does Urban Agriculture Enhance Dietary Diversity? Empirical Evidence from a Sample of Developing Countries
Provedor de dados: 31
Autores: Zezza,   Alberto; Tasciotti,   Luca.
Urban agriculture (UA) is defined as the production of crop and livestock goods within city and town boundaries. According to some statistics, 200 million people are employed in UA, contributing to the food supply of 800 million urban dwellers [1]. In African countries, 40 per cent of urban dwellers are said to be engaged in some sort of agricultural activities and this percentage rises to 50 per cent in Latin American countries [2]. If such numbers are accurate UA may play a role in addressing urban food insecurity problems. This paper attempts to fill some of the key research gaps in this area using survey data for 15 developing or transition countries. The paper analyzes in a comparative perspective the importance of UA for the poor and food insecure...

Poverty, Household Food Security, and Nutrition in Rural Pakistan
Provedor de dados: 31
Autores: Alderman,   Harold; Garcia,   Marito.
Designing strategies and policies that will alleviate poverty and improve household food security and nutritional well being is one of the most important challenges facing government policymakers in developing countries. The choice of strategies and policies depends in large part on understanding the dynamics of poverty, especially the mechanisms by which households acquire and spend income and cope with cries such as poor harvest or loss of employment. This work by Harold Alderman and Marito Gracia represents IFPRI's first comprehensive analysis of the longitudinal data on 800 households collected between 1986 and 1989 in Pakistan. This unique data set enables researchers to examine the temporal dimensions of food security, income and labor dynamics,...

Emerging Challenges for Food and Nutrition Policy in Developing Countries
Provedor de dados: 31
Autores: Stamoulis,   Kostas G.; Pingali,   Prabhu L.; Shetty,   Prakash.
As the income and the average caloric intake of developing country populations increase, a relative shift in diets is taking place. The general pattern of change can be described as a shift towards more 'westernized' diets and away from traditional ones. Accompanying this dietary trend are the substantial and rapid changes in food production, retailing and distribution systems. After reviewing these combined shifts and changes, the paper discusses the implications for rural poverty and food security, food safety and quality but also for diet-related non-communicable diseases and the related, emerging challenges for policymakers.

Trade, Tastes and Nutrition in India
Provedor de dados: 31
Autores: Atkin,   David.
This paper introduces habit formation into an otherwise standard model of international trade. Household tastes evolve over time to favor foods consumed as a child. The opening of trade causes preferred goods to rise in price, as these were relatively inexpensive in autarky. Neglecting the correlation between tastes and agro-climatic endowments overstates the short-run nutritional gains from agricultural trade liberalization and masks potential caloric losses for laborers. I examine the predictions of this model of trade with habit formation using household survey data from India, both by looking across Indian regions and by examining the consumption patterns of inter-state migrants.

Consumer Perceptions of, and Attitudes Toward, Rabbit Meat
Provedor de dados: 31
Autores: McLean-Meyinsse,   Patricia E.; Hui,   Jianguo; Meyinsse,   Joseph.
Results from a consumer-oriented study of households in Louisiana and Texas suggest that the nutritional properties of rabbit meat play a minor role in its consumption. In general, users regard rabbit meat as inferior to chicken, beef or pork and non-users are reluctant to try rabbit meat. Based on these results, the market for rabbit meat is likely to remain small, and rabbit production may not be a viable enterprise for farmers in this region of the country.

Effects of Impulsivity and Self-control on Calorie Intake
Provedor de dados: 31
Autores: Asirvatham,   Jebaraj; McNamara,   Paul E.
Neoclassical economic theory models individuals as making consistent choices over time and it assumes these choices are the outcome of rational utility maximization. Recent theoretical developments in the theory of consumer decision-making have drawn evidence from other disciplines such as, neuroscience (McClure et al, 2004) and psychology, and proposed more generalized models in a dual-self framework explicitly accounting for self-control or impulsivity (Gul and Pesendorfer, 2004; Fudenberg and Levine, 2006; and Brocas and Carillo, 2008). This study attempts to understand the dietary choices in a dual-self framework while explicitly identifying calorie intake owing to impulsivity and self-control. We construct standard psychological measures using the...

Food choice and food consumer behaviour is multifactoral behaviour, influenced by a large number of factors. Consumer way of life and health are relevant factors to understanding consumption preferences. In the last few decades the number of so-called civilization diseases has dramatically increased. Research has proved that the main cause for these diseases is the change in way of life; including rising stress in a fastpaced world and a lack of attention to physical activity and good nutrition. Nutrition and bad dietary habits have the greatest influence on weight gain and obesity, which are serious public health problems because the increased risk of premature death and civilization diseases like heart diseases, high blood pressure and diabetes.

The Response of Consumption to Income Shocks:  Evidence from the Indian Trade Liberalization
Provedor de dados: 31
Autores: Tandon,   Sharad; Landes,   Maurice R.
This paper uses the Indian tariff reforms of the early nineties to estimate how households responded to the negative income shocks caused by the tariff decreases.  Households more hurt by the tariff reform decreased overall expenditure, but the response is not uniform across food items.  In particular, households more hurt by the reform did not change their consumption of cereals, but decreased their consumption of all other food items.  Although this coping mechanism helped maintain overall levels of calorie consumption, diet diversity and the associated benefits were sacrificed.

The impact of smallholder commercialisation of organic crops on food consumption patterns, dietary diversity and consumption elasticities
Provedor de dados: 31
Autores: Hendriks,   Sheryl L.; Msaki,   Mark M.
The impact of smallholder commercialisation on food consumption patterns in a rural community of South Africa was investigated. The dietary diversity, nutrient intakes and consumption patterns of certified, partially certified and non-members of an organic farmers’ organisation were compared. Engagement in certified commercial organic farming promoted comparatively greater dietary diversity and improved nutrient intakes. While smallholder agriculture commercialisation has the potential to improve food consumption patterns and food quality through increased income and labour opportunities, caution should be exercised before claiming that such commercialisation can alleviate food insecurity and solve hunger in rural South Africa.

The Russian Federation is facing crucial dietary problems which burden the health care sector to an increasing degree. In order to correct this trend explanations for the observed mostly unhealthy diets are needed. Therefore the main target of this study was to find evidence about the main determinants of a healthy diet in the Russian Federation based on household production theory. In order to do that a healthy eating index for the Russian population was calculated according to the Diet Quality Index-International and used to describe the nutrition quality of the Russian diet. In a next step an empirical model was developed. In this model sociodemographic/socioeconomic variables were extended by the psychological variables such as overall dissatisfaction,...

Factors Affecting the Macronutrient Intake of U.S. Adults
Provedor de dados: 31
Autores: Variyam,   Jayachandran N.
The purpose of this study is to better characterize factors associated with the likelihood of macronutrient excess or inadequacy among U.S adults by modeling parts of the conditional distribution of dietary intakes other than the conditional mean. The risk of dietary inadequacy or excess faced by an individual tends to increase as his or her intake moves from the mean of a nutrient intake distribution toward its tails. Therefore, marginal effects of explanatory variables estimated at the conditional mean using ordinary least squares may be of limited value in characterizing these distributions. Quantile regression is effective in this situation since it can estimate conditional functions at any part of the distribution. Quantile regressions based on data...

The Asymmetric Effect of Dietary Knowledge on Nutrient Intake In China: Implications for Dietary Education Programs
Provedor de dados: 31
Autores: Shimokawa,   Satoru.
This paper demonstrates that dietary knowledge can influence nutrient intake differently depending on whether expected food availability is increasing or decreasing. Using data from China, we find that overall dietary knowledge has larger and more statistically significant effects on total calorie intake and the intake of three macro nutrients (carbohydrate, fat, and protein) when expected food availability increases than when it decreases. Without distinguishing the direction of changes in expected food availability, most of the corresponding effects become smaller and statistically insignificant. Thus, the effect of dietary knowledge on nutrient intake might have been underestimated in previous studies. We discuss the implications of these findings for...

Autores: Kumar,   Shubh K.
Enhanced agriculture productivity in sub-Saharan Africa is critical to promote economic growth and poverty alleviation and to avoid increasing food scarcities in the region. The impact of commercialization and intensification of agriculture on the well- being of the rural poor depends on how they are carried out. Past research by IFPRI and collaborating institutions on commercialization of small- scale farming in about a dozen countries provided new knowledge about the relationships between commercialization and rural well- being as measured by incomes, consumption, and nutrition. These links were shown to depend greatly on household behavior, which in turn is influenced by intrahousehold processes. A better understanding of these processes is likely to...

Production and Consumption of Foodgrains in India: Implications of Accelerated Economic Growth and Poverty Alleviation
Provedor de dados: 31
Autores: Sarma,   J.S.; Gandhi,   Vasant P.
The role of agriculture in India’s economic development continues to be of great importance, as a producer of food, as an employer of about two-thirds of the labor force, and as a source of purchasing power for much of the nonagricultural consumer goods and services in the economy. Thus, rapid growth in agricultural is essential for sustainable growth and development of the economy. Within agriculture, foodgrain production is by far the major activity, covering about 80 percent of the cropped area in India and providing the main staple source of food. Foodgrains provide almost all the calories and proteins consumed by the poor and provide the rural poor with the bulk of their employment and income. Further, with a population of some 800 million people,...

Nutrition labeling, in the words of the then FDA commissioner, David Kessler, was to “help millions of Americans make more informed, healthier choices.” Although the NLEA primarily focused on standardizing the nutrition facts label, its implementation also involved an informational and educational campaign on how to use the new nutrition facts label and the benefits of using it. Evidently label use more than doubled between 1989-91 and 1994-96. Most of the studies provide evidence of the effects of nutrition label use by comparing label users against non-users using data after NLEA was in effect. Using pseudo-panel data method, we find that implementing NLEA did not improve diet quality but use of labels did. Further, label usage showed no improvement in...

Autores: Calini,F; Sirri,F.
Vertical integration in poultry industry strongly emphasizes the importance of cost control at all levels. In the usual broiler production operations, the costs involved with the production of the hatching egg or the day old chick are negligible if seen in the perspective of the cost per kg of live bird. From a research point of view, anyway, the greatest attention is usually given to the performance of broiler breeders, and most of the research in the field is focused on the improvement of their relative performance, mainly in terms of saleable chicks produced per hen, while less attention has been given to the quality of the chick and to the improvement of its growth performances, even if these last parameters have an effective impact on the overall...

ABSTRACT Due to the emergence of large microalgae farms and increased competition in this sector, the search for higher productivity is common. One way to achieve this goal in microalgae production is to optimize the factors that influence their growth during the cultivation stage to increase the accumulation of bio-compounds of interest. In this stage, the factors that most influence are: nutrition, gas diffusion, light intensity and quality and, finally, stirring, which directly affects all other factors. Thus, a review and an evaluation of the influence and importance of stirring were performed in the present study. The nutrients that most influence biomass accumulation are carbon, nitrogen and phosphorus, but their proportion is directly related to the...

ABSTRACT Despite maintaining the green color in turfgrasses, nitrogen (N) fertilization affects shoot growth and, consequently, the frequency of cuts, the main factor in the costs of turfgrass maintenance. Therefore, this study aimed to evaluate N fertilization and the use of glyphosate as a growth regulator in Esmeralda grass (Zoysia japonica Steud.). The experiment was conducted in the field, from August 2014 to July 2015, using a randomized block design in a 5 x 4 factorial scheme with four repetitions and 20 treatments, namely: control (without N), 15 g m-2 of N in soil without foliar N; 30 g m-2 of N in soil without foliar N; 15 g m-2 of N in soil with foliar N (1% urea in 200 L ha-1) and 30 g m-2 of N in soil with foliar N combined with glyphosate...

Autores: Nomura,Edson S.; Cuquel,Francine L.; Damatto Junior,Erval R.; Fuzitani,Eduardo J.; Borges,Ana L.; Saes,Luis A.
ABSTRACT ‘BRS Princesa’ (AAAB) and ‘Caipira’ (AAA) banana cultivars have similar sensorial features in comparison to the ‘Maçã’ banana. They are resistant to Panama disease, which allows them to grow in the Ribeira Valley, the largest banana plantation area in the São Paulo State. However, there is no information on how to fertilize crop under these edaphoclimatic conditions. This study aimed to evaluate the development and production of ‘Caipira’ and ‘BRS Princesa’ bananas, by applying four fertilization doses of N and K2O (no fertilization; 175 and 285 kg ha-1 year-1; 350 and 570 kg ha-1 year-1; 525 and 855 kg ha-1 year-1). The most adequate fertilizer recommendation for ‘Caipira’ and ‘BRS Princesa’ cultivars was 150% of the standard recommendation for...

Yield and physical and chemical characteristics of 'Paluma' guava fruit were evaluated as a function of the harvest at different maturity stages, under influence of nitrogen and potassium fertilization, in Petrolina, State of Pernambuco, Brazil. Fertilizer rates were 67 kg N + 33 kg K2O, 133 kg N + 67 kg K2O, 200 kg N + 100 kg K2O and 267 kg N + 133 kg K2O per hectare. Fruits were evaluated at maturity stages 2, 3, 4 and 5, established according to peel color. Higher doses of N and K induced higher yields. Nevertheless, fertilization with 200 kg of N + 100 kg of K per hectare improved fruit quality, delaying ascorbic acid breakdown and conserving pulp firmness. Main changes took place at maturity stages 4 and 5, when the fruit should present ideal...

ABSTRACT  The custard apple tree (Annona squamosa L.), has increased in cultivation due to good prices in the national market. However, there are few studies regarding the fruit’s nutrition. The aim of this study was to verify the influence of N and K levels in developing the flower buds in two growing cycles, corresponding to the time of high temperatures (spring-summer) and another milder season (autumn-winter). The experiment was conducted in a rural property located in the municipality of Anagé, Bahia, installed in a randomised complete block design with 3 blocks, arranged in a factorial 4 x 4, obtained by the combination of the following levels of N (0, 16.875, 33.750 and 67.500 g plant-1) in the form of urea and K (0, 22.5, 45.0 and 90.0 g plant-1)...

Autores: Nomura,Edson Shigueaki; Cuquel,Francine Lorena; Damatto Junior,Erval Rafael; Bezerra,Daniela Peixoto; Borges,Ana Lúcia.
Abstract  There are several banana cultivars resistant to Black Sigatoka disease and to Panama disease, but due to the lack of information regarding post-harvest characteristics, many are rejected in the market. Nitrogen and potassium fertilization may help to improve the sensory characteristics of ripe banana, but there is lack of studies on its effects on banana cultivation, especially those resistant to diseases. The aim of this study was to evaluate the post-harvest characteristics of ‘Prata-Anã’, ‘BRS Platina’ and ‘PA94-01’ banana cultivars at four N and K2O fertilization levels (NK0: no fertilization, NK1: 175 and 285 kg ha-1 year-1, NK2: 350 and 570 kg ha-1 year-1, NK3: 525 and 855 kg ha-1 year-1, respectively) in three production cycles.

Preharvest calcium sprays were not always needed to improve quality of 'gala' apples in Brazil
Provedor de dados: 94
Autores: Ernani,Paulo Roberto; Dias,Jaques; Amarante,Cassandro Vidal Talamini do; Ribeiro,Diorvânia Cardoso; Rogeri,Douglas Antonio.
Calcium sprays have normally improved both the quality and the storage life of apples throughout the world because Ca helps to prevent many fruit disorders and that taken up from the soil does not often reach the fruit in adequate amounts. Since the efficacy of Ca sprays varies according to soil, apple cultivar, and weather conditions, this study was carried out from 1998 to 2004, in the Southern of Brazil, in order to assess the effect of Ca sprays on the quality and storability of 'Gala' fruits. The experiment was set up in an orchard planted in 1988, on a density of 1234 trees/ha. Treatments consisted of 0, 4, 8, and 12 annual sprays of 0.5% CaCl2 regularly distributed 30 days after petal fall until one week before harvest. Fruits of the same size and...

The relevance of age and nutritional status on the mating competitiveness of medfly males (Diptera: Teprhitidae)
Provedor de dados: 103
Autores: Roriz,Alzira Kelly Passos; Joachim-Bravo,Iara Sordi.
Results of previous investigations trying to ascertain which physiological factors are more important to the mating success of medfly males are controversial. In part, this controversy owes to the fact that each factor was evaluated by an independent study using different experimental designs and populations. In the present study we compare the roles of age and nutritional status (immature and adult phases) on the mating competitiveness of Ceratitis capitata (Wiedemann, 1824) males. Three parameters were used to evaluate the male mating success: calling behavior (pheromone emission), lek participation and copulation (ability to be chosen by a female). Females gave preference to the males that were given a high protein diet in the larval phase. By contrast,...

Stereotyped behaviors in captive primates are often caused by unsuitable conditions. Environmental enrichment has been used to reduce these behaviors, and also to increase the frequency of behaviors appropriate to the species. In this pilot study we evaluated whether behavioral enrichment influences food intake by the black tufted-ear marmoset, Callithrix penicillata (É. Geoffroy Saint-Hilaire, 1812), by calculating energy maintenance requirements. We evaluated 16 individually housed, healthy adult black tufted-ear marmosets, randomly divided into two treatment groups, one with behavioral enrichment and one without. The enrichment techniques included structural aspects, such as placing fixed and mobile objects in the cage and supplying dry foods in an...

Autores: Joachim-Bravo,Iara Sordi; Anjos,Cyntia Santiago; Costa,Anne Moreira.
In this paper, we investigated the influence of protein ingestion during the early adult phase on the sexual behavior of males of Ceratitis capitata (Wiedemann, 1824). The following parameters were evaluated: mating success (ability to be chosen by females), number of copulations, and copula duration. Experiments were carried out using a fifteen-year old laboratory lineage with the occasional introduction of wild flies. Two groups of adult males fed a high-protein diet during their larval phase were given either a high-protein diet (based on Brewer's yeast, concentration = 6.5 g/100 ml) or a no-protein diet. Both groups of males were exposed to females fed either a high-protein diet or a no-protein diet and were subsequently evaluated for the parameters...

ABSTRACT This study evaluated the effects of replacing ground corn with dehydrated guava (Psidium guajava L.) byproduct, at concentrations of 0.0, 8.2, 16.4, and 24.6% on the intake and digestibility of nutrients as well as on productive and economic performance of lambs. The study included 40 uncastrated feedlot Santa Inês sheep with an average age of 120 days and an average initial weight of 17.4±1.27 kg, distributed in individual stalls in a completely randomized design with four treatments and 10 replicates. Santa Inês sheep fed diets containing higher levels (16.4%) of guava byproduct showed lower weight gain and feed conversion and reached slaughter weight later. Replacing corn with guava byproduct at higher levels increased acid detergent fiber and...

Molecular methods to evaluate effects of feed additives and nutrients in poultry gut microflora
Provedor de dados: 96
Autores: Oviedo-Rondón,Edgar O.
Intestines of each animal are the niche of a complex and dynamic ecosystem with important effects to the host. The members or final products of this ecosystem influence nutrient digestion, absorption, mucosa metabolism, general physiology, and local and systemic immunological responses of avian hosts. Better understanding of the avian gut microbial ecosystem may lead to improvements on poultry productivity, health, welfare, and reduction of food borne pathogens and the environmental impact of poultry production for a more sustainable industry. Molecular methods of microbial ecology are key tools to gain this knowledge. The objective of this presentation is to outline the basic concepts, applications, advantages, limitations, and evolution of these...

The objective of this study was to evaluate the economic viability of feeding dairy cows with diets containing different levels of soybean oil. Cows were fed diets based on tropical forage (Pennisetum purpureum Schum) supplemented with different levels of soybean oil (0.0, 1.5, 3.0, and 4.5% of diet DM). The calculations were made considering the prices of the dietary ingredients and the daily consumption of each dietary treatment. The milk quality-based payment was estimated on the bonus paid for milk fat and protein contents according to two systems used by companies of the dairy sector. The economic benefit was calculated as the difference between the income obtained from milk sale and the cost associated with animal feeding. The MOP scenario analysis...

ABSTRACT This study aimed to evaluate the reproductive performance of female Nile tilapia (Oreochromis niloticus) fed diets containing different levels of digestible energy (DE). The fish were housed in 15 fiberglass tanks (500 L) in a recirculating system at an average temperature of 27.5 °C. The treatments consisted of five diets with increasing levels of DE (3,200; 3,400; 3,600; 3,800; and 4,000 kcal/kg). The levels of DE did not significantly influence the final weight or the hepatosomatic, gonadosomatic, and visceral fat indices. The absolute fecundity was influenced by the treatments, for which the highest values were observed from the 3,600 kcal/kg DE level and upward. The proximate composition of the fish also had a significant effect on the...

Nutritional genomics: a practical approach by early life conditioning with dietary phosphorus
Provedor de dados: 96
Autores: Ashwell,Christopher M.; Angel,Roselina.
The recent technologies that have led to the new field of functional genomics (how the genome of an organism regulates homeostasis and responds to stimuli) are providing a clearer understanding of how organisms interact with their environment and in particular their diet. We are beginning to learn how the diet may have long-term influence on performance and health. A form of epigenetic regulation has been recently described called fetal "programming". Fueled by epidemiological data the "fetal origins" hypothesis suggests that a poor in utero environment resulting from maternal dietary or placental insufficiency may "program" susceptibility in the fetus to cardiovascular or metabolic disorders. We have observed similar apparent programming by dietary...

Meta-analyses of experimental data in the animal sciences
Provedor de dados: 96
Autores: St-Pierre,Normand Roger.
In certain areas of animal research, such as nutrition, quantitative summarizations of literature data are periodically needed. In such instances, statistical methods dealing with the analysis of summary data (generally from the literature) must be used. These methods are known as meta-analyses. The implementation of a meta-analysis is done in several phases. The first phase defines the study objectives and identifies the criteria for selecting prior publications to be used in the construction of the database. Publications must be scrupulously evaluated for their quality before being entered into the database. During this phase, it is important to carefully encode each record with pertinent descriptive attributes (experiments, treatments, etc.) to serve as...

Two experiments were carried out with twenty-four male weaned Holstein calves to verify the influence of different dietary cation-anion concentrate and roughage proportions on calves metabolism. In the first experiment, calves were fed rations with -100, +200 and +400 mEq cation-anion balance/kg of dry matter, containing 60% of roughage and 40% of concentrate. In the second experiment, calves (117.6±20.8 kg average weight) received rations with similar dietary cation-anion balance but in diets of 40% roughage and 60% concentrate. As the dietary cation-anion balance became more positive, there was a quadratic response of blood pH in both diets with 60 and 40% roughage. A linear increase following increased dietary cation-anion balance was observed on...

Nutritional management and disease prevention in healthy dogs and cats
Provedor de dados: 96
Autores: Fascetti,Andrea J.
Healthy animals normally eat sufficient food to satisfy their energy requirements. It is one of the jobs of the nutritionist to ensure that all other nutrient needs have been met when animals stop eating because they have met their energy needs. While dogs and cats are members of the biological order Carnivora, scientific observation and research support that differences in their metabolism and nutritional requirements exist. However, the goal in feeding both species is the same; to optimize the health and well-being of the individual. This approach results in dietary recommendations that will vary from individual animal to animal, based on a variety of factors that include the animal's signalment, occupation and environment. Feeding approaches vary...

ABSTRACT The objective of the current study was to evaluate the effects of three calcium:available phosphorus (Ca:aP) ratios and different supplementation with phytases from different origins on performance and ash, Ca, and P contents in the tibia of broilers. A total of 900 male broilers (22 to 35 days old) were fed ten dietary treatments in a completely randomized design. A 3 × 3 + 1 factorial scheme was used, corresponding to three Ca:aP ratios (4.5:1.0, 6.0:1.0, and 7.5:1.0) and three different supplementations with phytases from different origins (isolated or combined supplementation with bacterial and fungal phytase), plus a control diet. Regardless of the dietary Ca:aP ratio, the isolated use of bacterial phytase provided better feed conversion than...

A model for evaluating beef cattle rations considering effects of ruminal fiber mass
Provedor de dados: 96
Autores: Henrique,Douglas Sampaio; Lana,Rogério de Paula; Vieira,Ricardo Augusto Mendonça; Fontes,Carlos Augusto de Alencar; Botelho,Mosar Faria.
A mathematical model based on Cornell Net Carbohydrate and Protein System (CNCPS) was developed and adapted in order to evaluate beef cattle rations at tropical climate conditions. The presented system differs from CNCPS in the modeling of insoluble particles' digestion and passage kinetics, which enabled the estimation of fiber mass in rumen and its effects on animal performance. The equations used to estimate metabolizable protein and net energy requirements for gain, net energy requirement for maintenance and total efficiency of metabolizable energy utilization were obtained from scientific articles published in Brazil. The parameters of the regression equations in these papers were estimated using data from Bos indicus purebred and crossbred animals...

Experimental approaches to study the nutritional value of food ingredients for dogs and cats
Provedor de dados: 96
Autores: Harmon,David L.
This review covers methods that have been applied to study the nutrient value or quality of specific ingredients fed to dogs, cats and comparable species (i.e. foxes, minks, rats, etc.). Typically, the nutritional value or utilization of a specific ingredient is measured by total tract digestibility and has been expanded through the measurement of total nutrient balance (i.e. nitrogen or energy). However, to better understand digestion it is necessary to obtain a more accurate measurement of nutrients entering and leaving the small intestine. Accurate measurement of small intestinal digestion is crucial in dogs and cats because nutrient digestion and absorption occurs primarily in the small intestine. Measuring small intestinal digestibility requires...

The objective of this study was to determine the effects of dietary energy and recombinant bovine somatotropin (bST) injection to identify genes that might control mammogenesis. Total RNA was extracted from the parenchymal tissue of 32 heifers randomly assigned to one of four treatments: two diets (a standard diet and a high energy, high protein diet), each with or without bST. To perform microarray experiments, RNA samples were pooled (2 animals/pool) before reverse transcription and labeling with Cy3 or Cy5. A 4-node loop design was used to examine the differential gene expression among treatments using a bovine-specific cDNA microarray (National Bovine Functional Genomics Consortium Library, NBFGC) containing 18,263 unique expressed sequence tags (EST)....

Autores: Tedeschi,Luis Orlindo; Fox,Danny Gene; Fonseca,Mozart Alves; Cavalcanti,Luigi Francis Lima.
Protein supply and requirements by ruminants have been studied for more than a century. These studies led to the accumulation of lots of scientific information about digestion and metabolism of protein by ruminants as well as the characterization of the dietary protein in order to maximize animal performance. During the 1980s and 1990s, when computers became more accessible and powerful, scientists began to conceptualize and develop mathematical nutrition models, and to program them into computers to assist with ration balancing and formulation for domesticated ruminants, specifically dairy and beef cattle. The most commonly known nutrition models developed during this period were the National Research Council (NRC) in the United States, Agricultural...

The majority of sheep milk produced in the world is transformed into cheese. Feeding is a major factor affecting the quality of sheep milk and, therefore, of sheep cheese. Because fat is the main compound of cheese, this review gives an update on the effects of feeding and nutrition on milk fat content and deeply discusses feeding strategies aimed at increasing the levels of healthy fatty acids (FA), such as conjugated linoleic acid and omega-3 FA, in milk and cheese in the human diet. In addition, the use of alternative feed resources such as by-products, aromatic plants, and phenolic compounds in the sheep diet and their effects on milk and cheese FA composition are also discussed. Among feeding strategies, grazing and the use of supplements rich in oils...

ABSTRACT  Cost and environmental restrictions limit the use of fishmeal (FM) in aquafeeds and plant protein (PP) sources. Soybean by-products are important alternative; however, their antinutritional factors may reduce fish growth. This study evaluates the effect of FM substitution for PP (soybean meal and soy protein concentrate) in diets of dourado (Salminus brasiliensis), a promising species for fish farming and empirically considered highly tolerant to PP-based diets. A control diet was formulated to contain 20 % of fishmeal and 61 % of plant protein (SBM) and other five diets with decreasing FM graded levels (16 %, 12 %, 8 %, 4 %, 0 %), which were replaced by soybean protein concentrate (SPC), comprising six treatments and four replicates.

Phytase enzyme in diets containing defatted rice bran for growing swine
Provedor de dados: 63
Autores: Moreira,José Aparecido; Vitti,Dorinha Miriam Silber Schmidt; Trindade Neto,Messias Alves da; Lopes,João Batista.
Organic phosphorus is poorly utilized by monogastric animals because they lack phytase, the enzyme that cleaves the ortho-phosphate groups from the phytate molecule. Diets fed to pigs are supplemented with inorganic P, and this can increase environmental pollution and diet costs. Sixty mixed sex, half-breed pigs, were used to evaluate the effect of increasing dietary levels of phytase (253, 759, 1265 and 1748 PU kg-1 feed) on animal performance as compared to a control without phytase but supplemented with dicalcium phosphate. Enzyme levels did not affect daily feed intake, food conversion, average daily weight gain, plasma P and Ca, calcium and phosphorus in bone ash, and the calcium/phosphorus ratio in the plasma and bones. A quadratic relationship...

Estimation of jundiá (Rhamdia quelen) dietary amino acid requirements based on muscle amino acid composition
Provedor de dados: 63
Autores: Meyer,Gustavo; Fracalossi,Débora Machado.
Jundiá, Rhamdia quelen (Quoy &amp;amp; Gaimard, 1824), is a catfish native to Central and South America. The species has a number of excellent farming features, such as easy handling, low temperature resistance, efficient feed conversion, flavorsome meat and absence of intramuscular bones, and has been increasingly raised in Southern Brazil. However, most of its nutritional requirements have not yet been determined, including the essential amino acid (EAA) requirements. The objective of the present study was to estimate such requirements through the determination of muscle tissue amino acid composition for four groups of jundiá. Two groups were wild caught and allocated in two categories: from 1 to 100 g and from 101 to 200 g. The other two groups,...

Autores: Carneiro,Paulo César Falanghe; Mikos,Jorge Daniel; Schorer,Marianne; Oliveira Filho,Paulo Roberto Campagnoli; Bendhack,Fabiano.
Live diet (LD) dependence and the lack of suitable formulated diets (FD) are major constraints for the expansion of larviculture of many fish species. The low digestibility and nutritional quality of FD are factors that might explain their failure as a stand-alone starter food. To determine whether FD in combination with LD (zooplankton) may efficiently increase larval growth and survival of jundiá (Rhamdia quelen), when compared to fish fed by either types of diet alone, jundiá larvae (5.57 mm; 1.41 mg) were initially stocked into 12 10-L aquaria (100 larvae per aquarium). Replicate groups (n=4) were fed ad libitum one of the three diets for 20 (when fed FD) or 48 days (when fed LD or the combined diets). Larvae fed FD alone presented significantly lower...

Effects that nutritional and saline gradients have on the growth of Passiflora mucronata Lam. and Canavalia rosea (Sw.) DC. found in the restinga of Brazil
Provedor de dados: 39
Autores: Lourenço Junior,Jehová; Zambom,Oberdan; Rossi,Magda Santos; Cuzzuol,Geraldo Rogério Faustini.
Salinity and fertility are the main factors cited in Within the restinga (coastal woodland) biome in Brazil, the positioning of Canavalia rosea and Passiflora mucronata occur, respectively, near the shore-in the creeping psammophyte formation (CPF) - and far from the shore - in the Palmae formation (PF). The hypothesis that such positioning is related to salinity and fertility was tested by applying a salt gradient (increasing solutions of NaCl) and a nutritional gradient (different proportions of Hoagland solution). Neither species survived in solutions over 200 mM of NaCl. The shoots of P. mucronata showed negative growth (lower dry mass) in the first week of exposure to saline solutions. The roots of C. rosea showed great sensitivity to salinity, which...

The ubiquitous gp63-like metalloprotease from lower trypanosomatids: in the search for a function
Provedor de dados: 42
Autores: Santos,André L.S.; Branquinha,Marta H.; D'Avila-Levy,Claudia M.
Plant and insect trypanosomatids constitute the "lower trypanosomatids", which have been used routinely as laboratory models for biochemical and molecular studies because they are easily cultured under axenic conditions, and they contain homologues of virulence factors from the classic human trypanosomatid pathogens. Among the molecular factors that contribute to Leishmania spp. virulence and pathogenesis, the major surface protease, alternatively called MSP, PSP, leishmanolysin, EC 3.4.24.36 and gp63, is the most abundant surface protein of Leishmania promastigotes. A myriad of functions have been described for the gp63 from Leishmania spp. when the metacyclic promastigote is inside the mammalian host. However, less is known about the functions performed...

Biological functions of selenium and its potential influence on Parkinson's disease
Provedor de dados: 42
Autores: ELLWANGER,JOEL H.; FRANKE,SILVIA I.R.; BORDIN,DIANA L.; PRÁ,DANIEL; HENRIQUES,JOÃO A.P.
ABSTRACT Parkinson's disease is characterized by the death of dopaminergic neurons, mainly in the substantia nigra, and causes serious locomotor dysfunctions. It is likely that the oxidative damage to cellular biomolecules is among the leading causes of neurodegeneration that occurs in the disease. Selenium is an essential mineral for proper functioning of the brain, and mainly due to its antioxidant activity, it is possible to exert a special role in the prevention and in the nutritional management of Parkinson's disease. Currently, few researchers have investigated the effects of selenium on Parkinson´s disease. However, it is known that very high or very low body levels of selenium can (possibly) contribute to the pathogenesis of Parkinson's disease,...

Most studies in nutrition for the South American catfish (surubim) were limited to the initial phase of development. However, it is clear that performance and nutrient utilization can change during the life stages of a fish. Therefore, this study aimed to evaluate the performance and nutrient utilization in juveniles of surubim fed diets varying in protein and energy levels. Two experiments were performed to test different levels of energy and protein in formulated diets. In the first experiment, surubim juveniles (89.2±4.8g) were fed five diets containing different levels of energy (18.0, 18.8, 19.6, 20.5, 21.3 MJ/kg). In the second experiment, juveniles (170.03±3.35g) were fed five diets containing different levels of protein (360, 400, 440, 480 and...

The performance and the morphology of intestinal mucosa of broilers fed mannan-oligosaccharides (MOS) and enzymes (E) from one to 21-day-old were evaluated using 750 one-day-old chicks, assigned to a 2 x 2 + 1 factorial design - two levels of MOS (0 and 0.1%), two levels of E (0 and 0.05%) plus an antibiotic positive control diet - performing five treatments of five replications each one. MOS x E interaction was significant for both duodenal (P&lt;0.002 and P&lt;0.002) and ileal (P&lt;0.04 and P&lt;0.05) perimeters and heights of villi, being the values lower in the mucosa of birds fed non-supplemented diets. MOS based-diet determined an increase on perimeter of jejunal villi (P&lt;0.05). Compared with antibiotic treatment group, villi perimeter...

A trial was carried out to determine the lysine requirement for starting barrows fed on ideal protein concept-based diets. Thirty-two pigs from a commercial crossbred genetic group (CCGG, BW=15.9 ± 1.4 kg) and 32 pigs from a dam line one (DLGG, BW= 14.8 ± 1.0 kg) were used. Pigs were allotted to 4 treatments with diets containing increasing levels of total lysine (0.80, 1.00, 1.20 and 1.40%). Methionine+cystine, threonine and tryptophan were adjusted according to ideal protein profile. Data from performance, plasma urea nitrogen (PUN) and carcass composition were analyzed. CCGG showed higher daily feed intake, daily weight gain, PUN and protein:fat ratio in carcass, while DLGG showed higher fat carcass content and nitrogen retention. Fat content and...

In this work, the effect of different densities (1, 3, 5, 7 and 9) of 3rd instar Alabama argillacea (Huebner) larvae on food consumption by Podisus nigrispinus (Dallas) males was evaluated. The densities established were converted to weight of prey offered: 13.4 mg (one larva), 33.3 mg (three larvae), 54.3 mg (five larvae), 81.8 mg (seven larvae), and 110.34 mg (nine larvae). The quantity of food consumed by P. nigrispinus increased with the prey density. The density of preys did not affect the time spent by the predator to ingest the food. The quantity of food extracted per minute was always higher in smaller densities and lower in higher densities. Males mean body weight did not differ statistically between the treatments tested, and weight gain was...

Ractopamine as a metabolic modifier feed additive for finishing pigs: a review
Provedor de dados: 52
Autores: Almeida,Vivian Vezzoni de; Nuñez,Amoracyr José Costa; Miyada,Valdomiro Shigueru.
The β-adrenergic agonist ractopamine is increasingly used in the swine industry due to higher consumer demand for leaner pork products. Redirecting nutrients to favor leanness rather than fat deposition, ractopamine improves growth and carcass traits of finishing pigs. However, the impact of this agonist on pork quality is not clearly defined. Understanding the biological effects of dietary ractopamine dose, treatment period, lysine levels, and the lysine to metabolizable energy ratio will help pork producers achieve improvements in animal performance, carcass leanness, and economic efficiency in swine production systems.

Provedor de dados: 52
Autores: Lopes,Marcos; Paroul,Natalia; Barbosa,Juliana; Valduga,Eunice; Cansian,Rogerio Luis; Toniazzo,Geciane; Oliveira,Débora.
ABSTRACT Among the nutrients involved in the chicken diet, the microminerals deserve attention as they exert essential functions in the organism. These compounds can be provided in inorganic (traditional) and organic (chelate) forms. In organic form, the micromimerals can attend a new concept related to a better bio-availability. In this sense, the objective of this work was to evaluate the effect of the partial and total substitution of inorganic by organic sources of microminerals on the animal diet, assessing its concentration in the blood and liver after 21 and 40 days and also in the bones after 40 days. Moreover, the effect on the physical-chemical and sensory characteristics of the muscle after 15 days of storage at 4°C was also evaluated. The...

Seasonal variations in body weight, food consumption and blood glucose, total lipids, urea, total proteins, albumin and globulins of captive Amazonian manatees, Trichechus inunguis, were determined. Body weight changed significantly along the year, increasing from autumn to spring and decreasing in summer. The mean daily food intake of paragrass remained almost unchanged along the year. Paragrass administered to the manatees showed important variations in crude protein and lipid content along the year. No significant differences in blood parameters were registered between males and females in all seasons. Further, there were no significant differences in blood total proteins, albumin and globulins along the year. On the other hand, significant differences...

Effect of ascorbic acid on food preference and consumption in captive capybaras (Hydrochoerus hydrochaeris)
Provedor de dados: 52
Autores: Alvarez,Martín Roberto; Kravetz,Fernando Osvaldo.
The aim of this work was to study the short and long term influences of ascorbic acid on Hydrochoerus hydrochaeris, if supplemented in their food. No differences regarding food intake were observed in the absence of vitamin C. On a daily basis, animals accustomed to food containing ascorbic acid prefered to continue eating the same food. Food preference in capybaras did not seem to depend on ascorbic acid availability; however, when accustomed to vitamin C, capybaras might recognize and select ascorbic acid in subsequent food. Mechanisms allowing capybaras to "evaluate" the nutritional quality of their food are discussed, as well as the adaptive value of this behavior in free ranging populations.

Our study evaluated how the consumption of diets with low (LOW group - 0.4/1) or high (CON group - 13.6/1) omega-6/omega-3 ratio across generations (F1 and F2) can modulate liver fatty acid (FA) profile and blood biomarkers. Liver content of α-linolenic acid was higher in animals always fed with LOW diet than animals that changed from CON to LOW diet, which by your time was higher than animals always fed with CON diet. Liver saturated FA concentration decreased in both groups from F1 to F2. In conclusion, both diets were efficient in decreasing the saturated FA liver content across generations, the LOW ratio diet was more effective in reducing blood triglycerides and non-esterified fatty acids, and there was a multigenerational effect of the LOW ratio...

Autores: Geraix,Juliana; Ardisson,Lidiane Paula; Marcondes-Machado,Jussara; Pereira,Paulo Câmara Marques.
Chagas disease (CD), caused by the protozoan Trypanossoma cruzi, affects approximately 18 million individuals in the Americas, 5 million of which live in Brazil. Most chronic sufferers have either the indeterminate form of the disease, without organic compromise, or the cardiac or digestive forms. Despite the importance of this disease, there is no information on the effect of nutrition on CD evolution. We evaluated the clinical-nutritional profile of individuals with CD treated at the Tropical Diseases Nutrition Out-Patient Clinic of the Botucatu School of Medicine, UNESP. A retrospective cohort study was performed between 2002 and 2006, on 66 patients with serum and parasitological diagnosis of CD. Epidemiological, clinical, nutritional, and biochemical...

Autores: Sprinz,Eduardo; Lazzaretti,Rosmeri Kuhmmer; Kuhmmer,Regina; Ribeiro,Jorge Pinto.
Metabolic complications continue to play a major role in the management of HIV infection. Dyslipidemia associated with HIV infection and with the use of combined antiretroviral therapy includes elevations in triglycerides, reduced high-density cholesterol, and variable increases in low-density and total cholesterol. The association between dyslipidemia and specific antiretroviral agents has been underscored. Multiple pathogenic mechanisms by which HIV and antiretroviral agents lead to dyslipidemia have been hypothesized, but they are still controversial. The potential clinical and pathological consequences of HIV-associated hyperlipidemia are not completely known, but several studies reported an increased risk of coronary artery disease in HIV-positive...

Autores: Vendramini,L.C.; Nishiura,J.L.; Baxmann,A.C.; Heilberg,I.P.
Because caffeine may induce cyst and kidney enlargement in autosomal dominant polycystic kidney disease (ADPKD), we evaluated caffeine intake and renal volume using renal ultrasound in ADPKD patients. Caffeine intake was estimated by the average of 24-h dietary recalls obtained on 3 nonconsecutive days in 102 ADPKD patients (68 females, 34 males; 39 ± 12 years) and compared to that of 102 healthy volunteers (74 females, 28 males; 38 ± 14 years). The awareness of the need for caffeine restriction was assessed. Clinical and laboratory data were obtained from the medical records of the patients. Mean caffeine intake was significantly lower in ADPKD patients versus controls (86 vs 134 mg/day), and 63% of the ADPKD patients had been previously aware of caffeine...

Malnutrition during lactation as a metabolic imprinting factor inducing the feeding pattern of offspring rats when adults: The role of insulin and leptin
Provedor de dados: 56
Autores: Moura,A.S.; Franco de Sá,C.C.N.; Cruz,H.G.; Costa,C.L.
The aim of the present study was to determine the impact of malnutrition during early postnatal life and the feeding pattern of rat offspring when adults (2 months and 1 year old). In comparison with rats normally fed during lactation, we observed that adult offspring displayed a faster process of feeding reduction when a protein-free diet was offered. In addition, we studied the concentration of insulin and leptin in the lactating pups (10 days) and when these offspring became adult after the onset of a new feeding pattern induced by the protein-free diet. When the diet was changed at 60 days, the offspring malnourished during lactation displayed, after 3 days, a food intake reduction around 41.4 vs 14.2% of the control group. At 10 days of life, plasma...

Provedor de dados: 58
Autores: Barroso,Cinthya Babá; Pereira,Gener Tadeu; Nahas,Ely.
The solubilization of inorganic phosphates by microorganisms supplies phosphates for plant nutrition and increases their growth. The solubilization of CaHPO4 (Ca-P) and AlPO4 (Al-P) by Aspergillus niger using several carbon and nitrogen sources was studied. Solubilization of Ca-P was enhanced when the carbon sources were mannitol, maltose, galactose and glucose (in that order). Galactose, sucrose and maltose were the carbon sources that enhanced the solubilization of Al-P. More extensive growth, acid production, and decrease in pH were obtained in the Al-P medium than in the Ca-P medium, however, the quantity of solubilized phosphate was 12% less. Phosphate solubilization was related to acid production, pH drop and fungal growth in the culture medium. The...

Autores: Torres-Leal,Francisco Leonardo; Capitani,Mariana Dutilh de; Tirapegui,Julio.
Recent studies of the effects of physical exercise and caloric restriction have found several benefits on the metabolic and cardiovascular risk factors related to metabolic syndrome (MS). This review examines the current state of knowledge of the effects of physical exercise on the main pathologies associated with MS: obesity, insulin resistance, type 2 diabetes mellitus (DM2), dyslipidemias and hypertension. Although there are only a few randomized and controlled studies that evaluated the prevention and treatment of MS, strong evidence from controlled studies indicates that lifestyle changes that include regular physical exercise and caloric restriction are effective in preventing and treating DM2 in overweight individuals with reduced glucose tolerance....

Using fishmeal as the main protein source with a substitution of either scallop viscera or Spirulina meal, three treatments were formulated to contain similar amounts of protein and energy. The experiment was run for 75 days, after which the tadpoles showed no significant differences among treatments in terms of their growth or survival. This is the first study to report positive effects of different diets on the growth and...

Autores: Oliveira,Rúbia Tabachi de; Haese,Douglas; Kill,João Luís; Lima,Anderson; Malini,Pablo Victor; Thompson,Guilherme Rodrigues.
ABSTRACT: Cat food formulation should not only meet the animal's nutritional needs, but also take into account food attractiveness. Our aim was to assess the palatability of food coated with sodium pyrophosphate and yeast extract, alone or in combination, and 20 adult cats were used in a two-bowl preference test. The preference for the experimental foods was tested by external application of sodium pyrophosphate (0.3%), yeast extract (0.2%), and a blend (0.5%) containing pyrophosphate and yeast extract in a same basal diet. In the present study, the cats showed preference for the blend (0.5%) containing sodium pyrophosphate and yeast extract.

Digestible energy of crude glycerol for pacu and silver catfish
Provedor de dados: 65
Autores: Balen,Rafael Ernesto; Tetu,Patrick Nereu; Bombardelli,Robie Allan; Pozza,Paulo Cesar; Meurer,Fábio.
The increase in global biodiesel production is originating a glycerol surplus, which has no defined destination. An alternative to overcome this problem is its use as energy source in animal feeding. In Brazil, Pacu (Piaractus mesopotamicus) is one of the most farmed native fish species, whereas Silver catfish (Rhamdia quelen) is suitable for production in subtropical region. Considering little knowledge about crude glycerol utilization in feeds for Neotropical fish species, it was evaluated the apparent digestibility coefficients (ADCs) for energy of crude glycerol for P. mesopotamicus and R. quelen. The digestibility and digestible energy content of crude glycerol can be considered excellent even when compared to energy of common ingredients such as...

ABSTRACT: The purpose of this study was to evaluate net energy and dietary ractopamine levels for barrows weighing 70 to 100kg. The 150 pigs investigated (initial weight 70.80±3.84kg) were distributed in a randomized block design with a 5×3 factorial arrangement, comprising five levels of net energy (2,300; 2,425; 2,550; 2,675; and 2,800Kcal kg-1 of diet) and three levels of ractopamine (5, 10, and 20ppm kg-1 of diet), with five replicates, and two animals per experimental unit. No interaction (P&gt;0.05) was observed between net energy and ractopamine levels. Increasing the dietary net energy levels led to a linear reduction in feed intake, with a linear improvement in feed conversion. Net energy levels had no observable effect (P&gt;0.05) on weight gain,...

Adequate methods for the determination of protein digestibility in bullfrogs are important for the understanding of nutrient utilization. Therefore, this study evaluated two methods of feces collection: intestinal dissection and fecal decantation, using cylindric-conical tanks. Frogs were fed with a commercial diet (45% crude protein) which was ground and supplemented with 0.5% chromium oxide III. The frogs were fasted 48h before force-feeding (5% of the animal's live weight). For the decantation method, the animals were sacrificed 36 h after force-feeding and feces were collected directly from the large intestine. For the sedimentation method, feces were collected when they appeared in the tubes attached to the front end of the cylindric tanks. No...

An experiment was conducted at the Department of Animal Husbandry of Universidade Federal de Lavras aiming to study the nitrogen and energy balance in diets with reduced crude protein rates (CP) and different levels of energy and lysine for growing pigs. 52 castrated pigs (initial weight = 36.13 ± 2.8 kg) of high genetic potential were used, housed individually in metabolism cages (experimental unit). The treatments consisted of 12 diets with three levels of metabolizable energy (ME) (3060, 3230 and 3400 kcal / kg) and four of true digestible lysine (TDL) (0.7, 0.9, 1.1 and 1, 3%) with 14% CP plus a control diet with 3230 kcal ME / kg, 1.03% TDL and 18% CP. We used a DBC in time 3x4 +1 factorial design with four replications to verify the absorbed nitrogen...

The aim of this work was to verify the effect of different levels of true digestible lysine (TDL) and crude protein (CP) on diets on the carcass composition of the swine in the nursery phase. Eighty piglets Landrace x Large White, barrows and females, with initial weight of 9.1±1.2 kg and final weight of 21.5±4.8 kg, weaned at the 28 days, allotted in groups of two during 35 days in the nursery. A randomized block design in factorial 2x4 (two levels of CP - 16 and 18% - and four of TDL - 0.7; 0.9; 1.1 and 1.3%) with five repetitions was used. After weighing, one animal of each stall was sacrificed and the carcass utilized for determination of water (CWP), protein (CPP) and lipid (CLP) percentage and deposition tax of the protein (DTP) and lipid (DTL)....

The experiment was carried out in the sheep division of Universidade Federal de Lavras, aiming to evaluate the effect of different concentrate : voluminous ratio on the performance of Santa Inês lamb after wean. 40 lambs, male uncastrated, were used and fed with four different diets: diet A (100% concentrate), diet B (75:25 concentrate : voluminous) , diet C (50:50 concentrate : voluminous) , diet D (25:75 concentrate : voluminous). The experimental diets were isoproteic, differing only on its levels of concentrate : voluminous and balanced to meet the nutritional demands according to the recommendation of the Agricultural Research Council (1980). The experimental period was not pre-established, because it corresponded to the necessary period for the last...

Currently, the use of alternative energy ingredients for horses has increased because these foods contain "superfibers", making safer diet for these animals. To study the influence of diets containing increasing levels of citrus pulp on albumin, triglycerides, cholesterol, glucose, insulin and short chain fatty acid (SCFA) concentrations in the blood, five animals were used, with an average age of 3.5 years and a live weight of 460.66±76.86 kg, they were fed twice a day, at 7:00 am and 4:00 pm. The diets were formulated to meet the requirements of the animals at maintenance. 60% of the energy was obtained from forage, and 40% from concentrate, containing the following inclusion levels of citrus pulp (0, 7, 14, 21 and 28%). The area under the curve (AUC)...

ABSTRACT Corn is a cereal whose productivity can be reduced by various diseases which has recommended treatments for control. The objective of this study was to analyze copper, zinc, calcium and manganese products for the management of Pantoea ananatis, Puccinia polysora and Cercospora zeae maydis in second season corn, and interference in agronomic characteristics. Commercial products made of amino acid chelated with 15% calcium, 5% copper, 15% manganese and 10% zinc, at the doses of 0.5 kg ha-1, 0.3 L ha-1, 0.4 kg ha-1 and 1 L ha-1, respectively, a treatment with fungicide (20% azoxystrobin and 8% cyproconazole at 0.3 L ha-1 + 25% propiconazole at 0.4 L ha-1), and a treatment with water were assayed. The experiments were carried out under field...
