14. Período de adaptação a dietas com baixa ou alta fibra sobre a digestibilidade e as características fecais em cães
RESUMO Objetivou-se avaliar três períodos de adaptação, cinco, 10 e 15 dias, a dietas com baixa ou alta fibra sobre a digestibilidade e características fecais. Foram utilizadas duas dietas, uma contendo 0% de casca de soja (0%CS) e outra com 15% de casca de soja (15%CS), fornecidas a 12 cães adultos. Ao final de cada período, houve coleta total de fez

16. Determination of nutrient and energy values of cottonseed meal supplemented or not with phytase and protease for broiler chicks
ABSTRACT The objective of this study was to determine the nutritional and energy compositions of cottonseed meal (CM), with or without enzyme supplementation, for broilers at different ages. A total of 672 male Cobb 500 chickens were distributed into four metabolism and ileal-digestibility trials. The experimental design was completely randomized, with four

17. Metabolizable Energy For Chickens Of High And Low Density Corn Fractions Segregated In Densimetric Table
ABSTRACT Corn is the main energy feed used in broiler chickens rations in most countries. In the literature, there are indications that high density corn segregated in densimetric table contains higher value of metabolizable energy than the corresponding fraction of low density, but the reasons are not clear. This study was conducted to determine the metabol

18. Complexos enzimáticos sobre a energia metabolizável e digestibilidade dos nutrientes do milheto para frangos de corte
RESUMO Objetivou-se avaliar o efeito de complexos enzimáticos sobre a energia metabolizável e o coeficiente de digestibilidade de nutrientes do milheto para frangos de corte. Quinhentos e setenta e seis frangos machos foram distribuídos em 36 gaiolas, com três tratamentos: T1 - composição de milheto sem complexo enzimático; T2 - composição de milhet

19. Performance and carcass characteristics of broilers fed whole corn germ
ABSTRACT The objective of this study was to evaluate the effect of including whole corn germ (WCG) on the performance; diet metabolizability; yields of carcass, cuts, and offal; and quality of meat of broilers. A total of 648 chicks were assigned to six treatments in a completely randomized design with six replicates, with 18 birds in each. Treatments consis

20. DIGESTIBILIDADE E PALATABILIDADE DE DIETAS COM EXTRATO DE PRÓPOLIS PARA CÃES
Resumo O objetivo do estudo foi avaliar o efeito da inclusão de extrato de própolis na digestibilidade e na palatabilidade de dietas para cães. Foram realizados dois experimentos, sendo o primeiro constituído por um ensaio de digestibilidade, com a inclusão de diferentes extratos de própolis (FT0,55, FT0,59, FT2,59, FT2,11). Com base nos resultados do

21. Effect of enzyme addition on energy utilization and performance of broiler chickens fed wheat-based diet with different metabolizable energy levels
ABSTRACT. An experiment was carried out to investigate the effect of multi-enzyme in high and low levels of metabolizable energy (13.81 and 11.51 MJ kg-1 diet) on performance and energy utilization of broilers fed wheat-soybean meal diets from 0 to 21 days of age. Result showed that birds fed diets containing 11.51 MJ kg-1 consumed significantly (p < 0.05) m

22. Metabolizable energy values of soybean meals and soybean oil for broilers at different ages
ABSTRACT. One trial with six analyses of different diets at different ages was carried out to determine the values of apparent (AME), corrected (AMEn), true (TME) and true corrected (TMEn) metabolizable energy of SBM and SBO for broiler chickens from 1 to 42 days of age. Three Brazilian SBM samples and one SBO were evaluated by replacing part of the basal di

23. Enzyme complex at different levels in diets with enriched ingredients for commercial laying hens
ABSTRACT The objective of this study was to evaluate levels of inclusion of an enzyme complex (EC) in corn- and soybean meal-based diets for laying hens on the digestibility of nutrients and energy. A metabolism trial was conducted using 75 Dekalb Brown laying hens at 26 weeks of age, which were distributed into five treatments with five replicates in a comp

24. Evaluating rumen fermentation kinetics and nutritive value of sunflower seed meal supplemented with acetonic extract of pomegranate peel using in vitro gas production technique
ABSTRACT. This study was conducted to investigate effects of supplementing different levels (0.0, 0.5 and 1.0% of buffered rumen fluid) of acetonic extract of pomegranate peel on rumen fermentation kinetics of sunflower seed meal (SFM), using in vitro gas production technique. The samples were incubated in syringes containing rumen liquor obtained from three
