Sunada,Natália da Silva; Orrico,Ana Carolina Amorim; Orrico Junior,Marco Antonio Previdelli; Lucas Junior,Jorge de; Lopes,Walter Renato Teixeira; Schwingel,Alice Watte.
ABSTRACT: This study aimed to obtain the best dose of waste cooking oil inclusion for the co-digestion of substrates prepared with dairy cattle and swine manure in order to maximize solids reductions and biogas yield. Analyses of total solids (TS), volatile solids (VS), and neutral detergent fiber (NDF) were performed during the loading and unloading of digesters, while biogas yield was measured twice a week. The maximum reduction in VS (51.4%) was reached with the inclusion of up to 54.6g waste cooking oil.kg manure-1. Maximum NDF degradation occurred with inclusions of up to 69.4g waste cooking oil.kg manure-1. Inclusions of up to 64g of waste cooking oil.kg manure-1 provided specific biogas yield of 291.4 and 251.0L biogas.kg VS-1 added to substrates...

Avaliação da bioacessibilidade de carotenoides em suco de melancia e produtos processados. Repositório Alice
CONSTANT, L. S.; GOMES, F. dos S.; RIBEIRO, A. P. de O.; GODOY, R. L. de O.; CABRAL, L. M. C..
Conhecida por suas agradáveis características sensoriais, a melancia é um fruto muito apreciado para consumo in natura. Ultimamente, tem sido relatada como uma importante fonte de licopeno, um pigmento associado à redução do risco de algumas doenças degenerativas. Diversos processos tem apresentado eficácia em concentrar e aumentar a estabilidade do licopeno a partir de frutas. Entretanto, tal incremento no teor desse composto não, necessariamente, implica em um aumento na quantidade absorvida pelo organismo humano e, consequentemente, na promoção da saúde do indivíduo de forma que a avaliação da liberação do composto durante a digestão, ou seja, a sua bioacessibilidade se faz necessária. Este trabalho objetivou adaptar um modelo de digestão in vitro para...

Chronic dietary exposure to pyrolytic and petrogenic mixtures of PAHs causes physiological disruption in zebrafish - part I: Survival and growth ArchiMer
Vignet, Caroline; Le Menach, Karyn; Mazurais, David; Lucas, Julie; Perrichon, Prescilla; Le Bihanic, Florane; Devier, Marie-hélène; Lyphout, Laura; Frere, Laura; Begout, Marie-laure; Zambonino-infante, Jose Luis; Budzinski, Helene; Cousin, Xavier.
The release of polycyclic aromatic hydrocarbons (PAHs) into the environment has increased very substantially over the last decades leading to high concentrations in sediments of contaminated areas. To evaluate the consequences of long-term chronic exposure to PAHs, zebrafish were exposed, from their first meal at 5 days post fertilisation until they became reproducing adults, to diets spiked with three PAH fractions at three environmentally relevant concentrations with the medium concentration being in the range of 4.6–6.7 μg g−1 for total quantified PAHs including the 16 US-EPA indicator PAHs and alkylated derivatives. The fractions used were representative of PAHs of pyrolytic (PY) origin or of two different oils of differing compositions, a heavy fuel...

Crude glycerin in diets for feedlot Nellore cattle R. Bras. Zootec.
van Cleef,Eric Haydt Castello Branco; Ezequiel,Jane Maria Bertocco; D'Aurea,André Pastori; Fávaro,Vanessa Ruiz; Sancanari,Juliana Borsari Dourado.
Two studies were conducted to evaluate the effects of crude glycerin on feed intake, performance, carcass characteristics, and total digestibility of Nellore bulls. In experiment 1, cattle (n = 30) were fed a control diet without crude glycerin and diets containing 7.5, 15, 22.5, and 30% crude glycerin, for 103 d. Animals were harvested and data of carcass characteristics were collected. In experiment 2, a digestibility trial was performed using indigestible acid detergent fiber (iADF) as internal marker, and five rumen-cannulated steers. Both experiments were conducted as a randomized complete block design and data were analyzed using mixed procedures. In experiment 1 no differences were observed among treatments on dry matter intake, and performance...

Cycles saisonniers, reproduction et qualite des ovocytes chez Pecten maximus en rade de Brest ArchiMer
Paulet, Yves-marie; Bekhadra, Farida; Devauchelle, Nicole; Donval, Anne; Dorange, Germaine.
This work is part of the program, "recruitment determinism in scallops" initiated in 1992 by the "Contrat de Baie". The aim of this research was to explain interannual abundance fluctuations observed for Pecten maximus, in the Bay of Brest. To this end an analytical approach to the life cycle of the species was undertaken to determine its critical phases. A phase may be considered as "critical" if the mortality rate at its level varies from one year to the other. Using data from 1989 to 1994, a precise time-table of the "physiological year" of the scallop in the Bay of Brest was determined. Fecundity and gamete production kinetics were estimated from the annual variation in the weight indices of the gonad. In the laboratory, egg quality was estimated...

Dietary neutral lipid level and source in marine fish larvae: Effects on digestive physiology and food intake ArchiMer
Morais, Sofia; Conceicao, L; Ronnestad, I; Koven, W; Cahu, Chantal; Zambonino, Jose-luis; Dinis, M.
A growth depressing effect of high dietary neutral lipid levels in marine fish larvae has been reported. This may be a result of a decrease in the efficiency or activity of digestive enzymes, a reduction in absorption efficiency and/or a decrease in food intake. The present work reviews recent studies carried out on commercially valuable species (Atlantic herring, Senegalese sole, European seabass and gilthead seabream) that investigated the effects of neutral lipid level and lipid source (fatty acid composition) on some of these key factors influencing larval growth. The results seem to collectively indicate that lipid transport from the enterocytes into the body may be more problematic in larval stages dealing with high neutral lipid diets than lipolytic...

Does gestation or feeding affect the body temperature of the golden lancehead, Bothrops insularis (Squamata: Viperidae) under field conditions? Rev. Bras. Zool.
Bovo,Rafael P.; Marques,Otavio A. V.; Andrade,Denis V..
Temperature affects physiological performance in reptiles and, therefore, body temperature (Tb) control is argued to have an important adaptive value. Alterations in Tb due to transient changes in physiological state, as during digestion or gestation, are often linked to the potential benefits of a more precise Tb regulation. However, such thermoregulatory responses in nature remain controversial, particularly for tropical snakes. Herein, we measured Tb of the golden lanceheads, Bothrops insularis (Amaral, 1921), at Queimada Grande Island, southeastern Brazil, to test for alteration in selected body temperatures associated with feeding or gestation. We found no evidence that postprandial or gravid snakes selected for higher Tb indicating that, under...

Dynamique et enzymologie de la digestion chez l'huitre Crassostrea gigas ArchiMer
Boucaud, C; Lebesnerais, C; Lubet, P; Lihrmann, I.
Feeding experiments carried out on Crassostrea gigas allowed the authors to set up the stages and the timing of the movement of food throughout the digestive tract. Various activities involved in digestion (glycosidases, esterases, and peptidases) were investigated histochemically in the digestive tract in order to localize the sites of absorption and the sites of protein and carbohydrate digestion. An explicative model of the different stages of digestion is proposed.

Early weaning of marine fish larvae onto microdiets: Constraints and perspectives ArchiMer
Person, L.
Weaning small sized marine fish larvae at first feeding directly onto compound pellets is still difficult, while good results can be obtained when used in combination with live prey or when a prefeeding period on live prey is provided up to a size of about 2-3 mg. Microdiets are generally well ingested as their acceptability and visual detection may be improved using feeding activators and increasing good perception contrast. In theory, food may be processed to have a correct nutritional balance, selection of high digestible components is very important as larval digestive system is not fully functional during the first 2 or 3 weeks of life.

Effect of adding macro and micro minerals in pig feces fed diets with different levels of probiotic BABT
Huaynate,Rizal Alcides Robles; Thomaz,Maria Cristina; Kronka,Rodolfo Nascimento; Fraga,Alessandro Luís; Scandolera,Antônio João; Budiño,Fábio Enrique Lemos.
This study aimed to verify the effect of diets with different doses (0, 100, 200 and 300 ppm) of probiotic on daily fecal production (DFP) and level of macro and micro minerals in feces of nursing (1st and 2nd initial phases) and growing pigs and during total period. The DFP, as percentage of body weight, was different (P<0.05) among treatments only at 1st initial phase. Fecal levels of macro and micro minerals were similar (P>0.05) among treatments, with exception of calcium and sodium excretion at 1st initial phase and calcium, zinc and nickel during total period. The addition of a poliprobiotic to diets do not affect fecal production of nursing and growing pigs. However, the presence of microorganisms, added (levels of 200 and 300 ppm) in diets...

Evaluation in situ digestibility of alfalfa in different grinds and textiles Animal Sciences
Kuwahara, Frank Akiyoshi; Souza, Gilberto Batista de; Ferreira, Reinaldo de Paula; Costa, Ciniro; Meirelles, Paulo Roberto de Lima.
Indigestible fractions of dry matter (iDM) and neutral detergent fiber (iNDF) in the feed of ruminants are mainly estimated by in situ incubation time with regard to particle size and textile types. Samples of alfafa, ground into three particle sizes, were analyzed. Samples, processed in a Willey mill with 1.0; 2.0 and 3.0 mm sieve pores, were conditioned in F57 (Ankon®), nonwoven (100 g m-2) and polyester textile bags measuring 4 x 5 cm. Material was divided into 13 incubation periods and 8 replications, and incubated in the rumen of two multiparous cows adapted to a 70:30 diet, roughage:concentrate, respectively, for 288h. iDM and iNDF rates were evaluated sequentially for non-digested percentage and data underwent analysis of variance (ANOVA p <...

Experimental approaches to study the nutritional value of food ingredients for dogs and cats R. Bras. Zootec.
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...
