1. In vitro evaluation of the association of chitosan and cashew nut shell liquid as additives for ruminants
RESUMO Objetivou-se avaliar no presente trabalho a digestibilidade in vitro de nutrientes de diferentes dietas com a adição de quitosana (Q), líquido da casca da castanha de caju (LCC) e a associação entre Q e LCC. Os tratamentos utilizados foram constituídos de 4 dietas (relação volumoso:concentrado, 100:0, 50:50, 40:60 e 20:80) associadas com 4 adi

2. Protein and carbohydrate fractionation of Jiggs Bermudagrass in different seasons and under intermittent grazing by Holstein cows
ABSTRACT. Jiggs bermudagrass has presented competitive production potential over other forages. However, there is a lack of information about the nutritional value of this forage with important relevance in ruminant nutrition. This study aimed to evaluate the protein and carbohydrate fractionation of Jiggs bermudagrass in different seasons of the year under

3. Use of dual-energy x-ray absorptiometry in non-ruminant nutrition research
ABSTRACT Precise body composition measurements are essential in animal nutrition studies because the impact of treatments is evaluated based on changes in body weight and composition. Various indirect techniques for animal compositional evaluation have been developed and evaluated for applicability in animal nutrition studies. A fast, accurate, minimally inv

4. A glimpse of the future in animal nutrition science. 1. Past and future challenges
ABSTRACT If the world population continues to increase exponentially, wealth and education inequalities might become more pronounced in the developing world. Thus, offering affordable, high-quality protein food to people will become more important and daunting than ever. Past and future challenges will increasingly demand quicker and more innovative and effi

5. Sulfur sources in protein supplements for ruminants
The present study evaluates the efficiency of different sulfur sources for ruminant nutrition. The fiber digestibility and the amino acid profile were analyzed in the duodenal digesta of crossbred steers fed Brachiaria dictyoneurahay. The sources utilized were elemental sulfur (ES70S), elemental sulfur (ES98S); calcium sulfate in hydrated (HCS), CaSO4.2H2O,

6. Inclusão de grão de milheto em dietas de alto concentrado para ovinos em confinamento / Inclusion of a grain of corn in diets high concentrate for sheep in confinement
The ovine production is an activity that has developed gradually in the country, and growing in areas where before the sheep industry was negligible, enabling livestock production systems in small, medium and large farms and becoming a more profitable alternative investment means in agriculture, when compared with other agricultural as for example, beef catt

7. Inclusão de grão de milheto em dietas de alto concentrado para ovinos em confinamento / Inclusion of a grain of corn in diets high concentrate for sheep in confinement
A produção de ovinos é uma atividade que vem se desenvolvendo gradativamente no país, e crescendo em regiões em que antes a ovinocultura era insignificante, viabilizando sistemas de produção animal em pequenas, médias e grandes propriedades rurais e tornando-se mais uma alternativa rentável de investimento no meio agropecuário, quando comparados co

8. Desempenho de bovinos alimentados com dietas contendo enzimas amilolíticas exógenas / Performance of cattle feed with diets containing amylolytic enzymes exogenous
O uso de ionóforos como promotores de crescimento em bovinos de corte está sendo colocado como barreira pelos países da União Européia para a exportação de carne bovina. Diante desse desafio, novos produtos estão sendo pesquisados para incrementar o desempenho animal, dentre os quais aqueles contendo atividade enzimática. O presente trabalho teve co

9. FONTES DE CARBOIDRATOS PARA TERMINAÇÃO DE BOVINOS DE CORTE: DESEMPENHO E CARACTERÍSTICAS DA CARCAÇA E DA CARNE / SOURCES OF CARBOHYDRATES FOR STEERS FINISHING: PERFORMANCE AND CARCASS CHARACTERISTICS AND MEAT
The objective of this study was to evaluate the effect of three carbohydrate sources (corn, soybean hulls or wheat bran) in the diet on performance, carcass characteristics and meat and the components are not part of the carcass of steers finished on confinement. We used 24 steers, crossbred Charolais x Nellore, with initial age of 22 months of initial body

10. Efficiency of metabolizable energy utilization for maintenance and gain and evaluation of Small Ruminant Nutrition System model in Santa Ines sheep
This study was carried out to estimate efficiencies of the utilization of metabolizable energy for maintenance (k m) and weight gain (k g) and to evaluate the Small Ruminant Nutrition System (SRNS) model in predicting dry matter intake and average daily gain of growing Santa Ines sheep. Twenty-four non-castrated Santa Ines sheep, at 50 days of age and with a

11. Uréia na alimentação de vacas leiteiras.
ABSTRACT: Urea is a non protein nitrogen compound that can be used to replace protein sources usually offered in ruminant nutrition. It is a technology that can be efficiently used in dairy cow nutrition, assuring good production levels. Taking to account the ruminant metabolism, the efficiency of urea use by ruminal microorganisms depends on the correct die
