2. Amino Acid Digestibility of Feed Ingredients in Cecectomized Adult Roosters
ABSTRACT A digestibility assay was conducted in order to determine the digestibility coefficients (DC) of amino acids of feed ingredients in cecectomized adult roosters. In total 48 cecectomized adult roosters were used to assess the coefficient of digestibility of 7 ingredients: corn, soybean meal, soybean concentrate, corn gluten meal, wheat bran, peanut m

3. The Role of ß-Mannanase (Hemicell) in Improving Poultry Productivity, Health and Environment
ABSTRACT The poultry nutritionists constantly attempt to identify and alleviate the factors responsible for adverse effects on nutrient utilization and production performance in avian species, which are necessary for successful productivity of poultry. Enhanced feed utilization can reduce levels of some nutrients in the diet with concomitant mitigation in nu

4. Grapeseed Meal Used as Natural Antioxidant in High Fatty Acid Diets for Hubbard Broilers
ABSTRACT The 7-week feeding trial evaluated the effect of 2% grapeseed meal used as natural antioxidant in the diets for slow-growing Hubbard broiler chicks, aged 14 days. The chicks were weighed individually and assigned to two groups (C and E), with 40 chicks per group, housed under conditions of temperature, humidity and light regimen according to the hyb

5. Da obrigação de alimentar os escravos no Brasil colonial
Resumo Para se servirem dos braços escravizados dentro do que se compreendia, então, como justo, aos senhores concorria uma série de deveres. Entre os recorrentemente elencados como essenciais e irrefutáveis, três saltam aos olhos: vesti-los adequadamente, castigá-los com justiça, e alimentar-lhes os corpos. Aqui, pois, tomando o último desses aspect

7. Phosphorus utilization in broilers fed with diets supplemented with different feed ingredients
ABSTRACT: A reliable determination of endogenous phosphorus (P) excretion is required to measure P utilization in chickens accurately. The objective of this study was to investigate phosphorus (P) retention in broilers fed diets formulated with different feed ingredients. Sixty-four 15-d old broiler chicks were fed diets in which part of the dietary P was pr

8. Growth and digestive enzymes of silver catfish fed diets containing fruit residue
RESUMO Na piscicultura, o uso de ingredientes alternativos vem sendo estudado, de modo que seja possível utilizar fontes alternativas para minimizar custos com a alimentação. Neste estudo, foi avaliada a incorporação de resíduos de uva, laranja, goiaba e figo em rações para jundiá e seus efeitos no crescimento, em enzimas digestivas e na composiçã

9. Intake and digestion of non-traditional feedstuffs by farmed collared peccary (Mammalia, Tayassuidae)
ABSTRACT To assess the ability of the collared peccary ( Pecari tajacu ) to digest dietary fiber, four adult male collared peccaries were randomly assigned to a 4 × 4 Latin square design to determine the effects of feeding non-traditional feed ingredients, taken from palm trees with different levels of dietary fiber, on intake and coefficient of total tract

10. Performance and carcass characteristics of goats fed crude glycerin in the feedlot and during pre-slaughter lairage
ABSTRACT This study evaluated the effects of crude glycerin (CG) supplied separately from the other dietary ingredients to goats during the feedlot and in the pre-slaughter lairage on the nutrient intake, performance, behavioral and physiological parameters, carcass characteristics, and meat quality. Twenty-eight uncastrated male goats from a cross between t

12. Feed type for induced molting of commercial layer hens
An experiment employing three hundred and twenty 81-week-old Lohmann LSL commercial-breed hens was conducted to compare alternative induced-molting methods with the conventional method (fasting). Induced molting lasted 28 days at most, production and quality being monitored for four periods of 28 days thereafter. A completely randomized experimental design w
