Aerobic scope explains individual variation in feeding capacity ArchiMer
Auer, Sonya K.; Salin, Karine; Anderson, Graeme J.; Metcalfe, Neil B..
Links between metabolism and components of fitness such as growth, reproduction and survival can depend on food availability. A high standard metabolic rate (SMR; baseline energy expenditure) or aerobic scope (AS; the difference between an individual's maximum and SMR) is often beneficial when food is abundant or easily accessible but can be less important or even disadvantageous when food levels decline. While the mechanisms underlying these context-dependent associations are not well understood, they suggest that individuals with a higher SMR or AS are better able to take advantage of high food abundance. Here we show that juvenile brown trout (Salmo trutta) with a higher AS were able to consume more food per day relative to individuals with a lower AS....

Beyond protein intake: bushmeat as source of micronutrients in the Amazon Ecology and Society
van Vliet, Nathalie; Center for International Forestry Research (CIFOR); vanvlietnathalie@yahoo.com; Schor, Tatiana; Geography Department, Universidade Federal do Amazonas; tschor@ufam.edu.br; Tellez, Leady; Independent consultant; leadyjot@hotmail.com.
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...

Calculations of results in grazing experiments using the counting method OMA
Tackx, M.L.M.; Van de Vrie, E.M..
Different formulae used in the literature for calculation of ingestion rates are reviewed. Their applicability is discussed in relation to two criteria: the occurrence of saturation of the feeding and/or growth of the food particles. It is shown by simulations that the differences in results obtained by calculating ingestion following a linear or an exponential model are restricted to a few percent. Calculation of ingestion rates by substantial over- or underestimation depending on the growth constant of the food particles and the grazing time.The formula I = Vk(C<sub>zt</sub>C<sub>zo</sub>e<sup>kt</sup>)/N(I-e<sup>kt</sup>) is proposed for the calculation of ingestion rates under saturated circumstances.It...

CRF1/CRF2 and MC3/MC4 Receptors Affect Glutamate- Induced Food Intake in Neonatal Meat-Type Chicken Rev. Bras. Ciênc. Avic.
Ahmadi,F; Zendehdel,M; Babapour,V; Panahi,N.
ABSTRACT Central glutamate, melanocortin and corticotropin systems have mediatory role on several physiologic functions in the brain, but their interactions on appetite regulation are not fully elicited. So, the aim of the current study was to determine interaction of the glutamate with melanocortin and corticotropin systems on food intake in 3-h food-deprived (FD3) neonatal meat-type chicken. In experiment 1, chicken intracerebroventricular (ICV) injected (A) phosphate-buffered saline (PBS), (B) glutamate (75 nmol), (C) glutamate (150 nmol) and (D) glutamate (300 nmol). In experiment 2, (A) PBS, (B) astressin-B (CRF1/CRF2 receptors antagonist, 30 µg), (C) glutamate (300 nmol) and (D) astressin-B+glutamate were ICV injected. Experiments 3-5 were similar to...

Evaluation of association of DRD2 TaqIA and -141C InsDel polymorphisms with food intake and anthropometric data in children at the first stages of development Genet. Mol. Biol.
Feistauer,Vanessa; Vitolo,Márcia R.; Campagnolo,Paula D.B.; Mattevi,Vanessa S.; Almeida,Silvana.
Abstract The reward sensation after food intake may be different between individuals and variants in genes related to the dopaminergic system may indicate a different response in people exposed to the same environmental factors. This study investigated the association of TaqIA (rs1800497) and -141C InsDel (rs1799732) variants in DRD2/ANKK1 gene with food intake and adiposity parameters in a cohort of children. The sample consisted of 270 children followed until 7 to 8 years old. DNA was extracted from blood and polymorphisms were detected by PCR-RFLP analysis. Food intake and nutritional status were compared among individuals with different SNP genotypes. Children carrying the A1 allele (TaqIA) had higher energy of lipid dense foods (LDF) when compared...

Evaluation of the association between the TAS1R2 and TAS1R3 variants and food intake and nutritional status in children Genet. Mol. Biol.
Melo,Silvia V.; Agnes,Grasiela; Vitolo,Márcia R.; Mattevi,Vanessa S.; Campagnolo,Paula D.B.; Almeida,Silvana.
Abstract Taste perception plays a key role in determining individual food preferences and dietary habits and may influence nutritional status. This study aimed to investigate the association of TAS1R2 (Ile191Val - rs35874116) and TAS1R3 (-1266 C/T - rs35744813) variants with food intake and nutritional status in children followed from birth until 7.7 years old. The nutritional status and food intake data of 312 children were collected at three developmental stages (1, 3.9 and 7.7 years old). DNA was extracted from blood samples and the polymorphisms were analyzed by real-time polymerase chain reactions (qPCR) using hydrolysis probes as the detection method. Food intake and nutritional status were compared among individuals with different single nucleotide...

Food preferences of cockatiel chicks ( Nymphicus hollandicus ) in captivity Arq. Bras. Med. Vet. Zootec.
Naves,D.A.S.; Carvalho,T.S.G.; Zangeronimo,M.G.; Saad,C.E.P.; Scalon,J.D..
ABSTRACT In order to improve the management and maintenance of the quality of life of captive wild birds, this study aimed to assess the food preferences of cockatiel chicks (Nymphicus hollandicus) kept in captivity. Thirty-two cockatiel chicks, three to 12 months of age, were kept in a galvanized, wire-netted vivarium with six ceramic feeders, two for an extruded diet, two for a dry-mashed diet and two for a seed mixture. Both extruded and dry-mashed food are commercial psittacine diets. Three round ceramic pots were used to provide water. The birds were exposed to 12 hours of artificial light (40 W incandescent lamps) during the experimental period of 27 days. The birds were observed by video filming, daily, through an ad libitum observation technique....

Involvement of Gaba and Cannabinoid Receptors in Central Food Intake Regulation in Neonatal Layer Chicks: Role of CB1 and Gabaa Receptors Rev. Bras. Ciênc. Avic.
Zendehdel,M; Tirgari,F; Shohre,B; Deldar,H; Hassanpour,S.
ABSTRACT Feeding behavior is regulated via a complex network which interacts via diverse signals from central and peripheral tissues. Endocannabinoids modulate release of GABA in a variety of regions of the central nervous system. Endocannabinoids and GABAergic system have an important role in the central regulation of appetite. Thus, the present study examines the possible interaction of central canabinoidergic and GABAergic systems on food intake in 3-h food-deprived (FD3) neonatal layer-type chicks. The results of this study showed that intracerebroventricular (ICV) injection of 2-AG (2-Arachidonoylglycerol, selective CB1 receptors agonist, 2µg) significantly increased food intake and this effect of 2-AG was attenuated by Picrotoxin (GABAA antagonist,...

Leaf consumption by Diabrotica speciosa (Coleoptera: Chrysomelidade) adults on difFerent host plants Scientia Agricola
Ávila,Crébio José; Parra,José Roberto Postali.
Studies related to the feeding behavior of pest insects provide information that will aid the development of control tactics. Leaf consumption by Diabrotica speciosa adults fed on bean, corn, potato and soybean was determined in the laboratory under free-choice (multiple or double-choice) and no-choice (confinement) conditions. In the multiple-choice tests leaf circles were randomly arranged in a circular pattern (arena) inside Petri dishes. The degree of preference for the hosts was determined under double-choice conditions, where common bean was considered the standard host and the remaining plants (soybean, potato and corn) as test hosts. In all trials, two Diabrotica speciosa couples were released and maintained within the dish for 24 hours; the leaf...

Main food sources of carotenoids, according to the purpose and degree of processing, for beneficiaries of the 'Bolsa Família' in Brazil Ciênc. Tecnol. Aliment.
Sartori,Alan Giovanini de Oliveira; Silva,Marina Vieira da.
The intake of carotenoids is associated with antioxidant properties and some of these substances have activity of pro-vitamin A. This study aimed to estimate the intake of carotenoids (average values) by the Brazilian population focusing on beneficiaries of the 'Bolsa Família' Program and identify the dietary sources, according to the purpose and degree of processing and the inclusion of food additives. The database used is the personal food consumption module of the Household Budget Survey of 2008-2009, conducted by the Brazilian Institute of Geography and Statistics. The content of carotenoids in foods was obtained primarily from a National data source. Food products were classified into three categories: 1) fresh and minimally processed foods; 2)...

Take off the heater: Utility effect and food environment effect in food consumption decisions AgEcon
Lombardini-Riipinen, Chiara; Lankoski, Leena.
In this paper, we describe individual food consumption decisions as driven by a utility effect and a food environment effect. To outline the utility effect, we first develop a new theoretical model of individual food consumption. Next, we introduce the food environment effect by showing how the food environment can affect food consumption decisions and how this can skew the resulting food consumption vector. Finally, we analyse manipulations of the food environment as a potential form of policy intervention. Our key result is that the food environment has several entry points in food consumption decisions and that libertarian paternalistic manipulations of the food environment can be effective, easily implemented, well-accepted and low-cost intervention...

Tasas de defecación en venado cola blanca (Odocoileus virginianus) a partir del contenido de fibra en heces. Colegio de Postgraduados
Vega Hernández, Dania Melissa.
El método indirecto de conteo de grupos fecales es muy empleado en la estimación de poblaciones de venado. Para realizar su estimación es necesario utilizar un índice fecal, lo que se conoce como tasa de defecación. Sin embargo, existe gran variación entre las tasas a emplear lo que hace cometer errores al estimar la densidad de población en una determinada área, independientemente de la semejanza en hábitat, lo que puede acarrear estimaciones y decisiones equivocadas en el manejo y aprovechamiento de la especie. Considerando lo anterior, se planteó la construcción de modelos para estimar las tasas de defecación de venado cola blanca a partir de los contenidos de fibra detergente neutro (FDN) y fibra detergente ácido (FDA) en heces. De mayo de 2012 a junio...

THE EFFECT ON DIETARY QUALITY OF PARTICIPATION IN THE FOOD STAMP AND WIC PROGRAMS AgEcon
Wilde, Parke E.; McNamara, Paul E.; Ranney, Christine K..
Participants in the Food Stamp Program consume more meats, added sugars, and total fats than they would in the absence of the program, while their consumption of fruits, vegetables, grains, and dairy products stays about the same. Participants in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) consume significantly less added sugars, which may reflect the substitution of WIC-supplied juices and cereals in place of higher sugar soft drinks and cereals. These findings come from a study of low-income Americans using the Continuing Survey of Food Intake by Individuals.

The neuroimmune-endocrine axis: pathophysiological implications for the central nervous system cytokines and hypothalamus-pituitary-adrenal hormone dynamics BJMBR
Licinio,J.; Frost,P..
Cytokines are molecules that were initially discovered in the immune system as mediators of communication between various types of immune cells. However, it soon became evident that cytokines exert profound effects on key functions of the central nervous system, such as food intake, fever, neuroendocrine regulation, long-term potentiation, and behavior. In the 80's and 90's our group and others discovered that the genes encoding various cytokines and their receptors are expressed in vascular, glial, and neuronal structures of the adult brain. Most cytokines act through cell surface receptors that have one transmembrane domain and which transduce a signal through the JAK/STAT pathway. Of particular physiological and pathophysiological relevance is the fact...

What hormones may regulate food intake in fish ? ArchiMer
Le Bail, Pierre-yves; Boeuf, Gilles.
This is an overview of the hormones which may be involved in food intake control in fish, and some hypothetical pathways of their action are given based on mammalian knowledge. Most of the observed effects of these hormones may result from four types of mechanisms, each hormone acting by one or several as follows: (1) hormones could have a direct effect on central nervous system centres, associated with food intake behaviour or via vagal afferent neurons; (2) an indirect effect may occur via the gut which slows gastrointestinal transit, thus resulting in stomach distention which activates vagal afferent neurons; (3) they could have an indirect effect, acting directly on intermediary metabolism via glucose, flee fatty acids or amino acids mobilization or...
