1. Effects of antibiotic growth promoters and concentrate on intake, digestibility, degradability, and ruminal variables in beef steers
RESUMO O objetivo foi avaliar a adição de antibióticos promotores de crescimento ao concentrado sobre o consumo, digestibilidade, degradabilidade in situ e variáveis ruminais de novilhos. Quatro novilhos em um delineamento quadrado latino foram alimentados com feno (ad libitum), concentrado [10g kg-1 do peso corporal (PC)] e mistura mineral (0,272g kg-1

2. Degradability and kinetics of fibrous particles in cattle fed diets based on corn silage and concentrates with or without addition of lipids
ABSTRACT Eight rumen-cannulated steers were assigned to two 4 × 4 balanced Latin squares to evaluate degradability and kinetics of fiber particles from diets based on corn silage and supplements with or without addition of lipids. Dietary treatments were: only corn silage (T1), corn silage plus concentrate with no added lipids (T2), corn silage plus concent

3. Effects of lines and inoculants on nutritive value and production costs of triticale silages
ABSTRACT The current study was undertaken to investigate the ensilage characteristics in triticale lines treated by inoculants and their interaction on fermentation metabolites and rumen degradability. Costs were estimated for growing and feeding whole-crop triticale lines for animal production. Triticale hybrids were harvested at the dough stage of maturity

4. Nutritional evaluation of elephant-grass silages with different levels of by-products from the cashew juice industry
ABSTRACT This study was conducted to evaluate the intake, apparent digestibility (AD), and degradability in situ of elephant grass (Pennisetum purpureum Schum) silages containing 0, 35.0, 70.0, 105.0, and 140.0 g kg-1 by-product from dried cashew apple (DCBP) (as fed basis). A completely randomized design with four replicates was adopted. For the study of de

5. Kinetics of transit and degradation of the fiber from guinea grass silages enriched with waste from soybean pre-cleaning
The objective was to study the kinetics of transit and degradation of the fiber from guinea grass and the waste from soybean pre-cleaning (WSPC), ensiled with different proportions of mass (0, 100, 150, and 200 g WSPC/kg total mass). Four crossbred (Gyr × Holstein), fistulated cattle with an average body mass of 400±50 kg were organized in a 4 × 4 Latin s

6. Slow-release urea in supplement fed to beef steers
Replacing regular urea (RU) by slow-release urea (SRU) at two levels of non-protein nitrogen (NPN) in concentrate, offered with low-quality roughage, was evaluated in beef steers on dry matter intake (DMI), ruminal fermentation parameters, plasma urea nitrogen (PUN), total tract apparent digestibility of diets and in situ degradability of nitrogen sources. E

7. Particle passage kinetics and neutral detergent fiber degradability of silage of pineapple waste (aerial parts) under different packing densities
The objective of this study was to determine the kinetics of in situ degradability parameters of the dry matter (DM) and neutral detergent fiber (NDF) and the passage of materials originating from the ensilage of the waste from pineapple cultivation (aerial parts). The four treatments utilized were silage of pineapple waste compacted at 600, 700, 900 and 100

8. Potential of wet blue leather waste for ruminant feeding
The objective of this study was to find an alternative to minimize environmental contamination by leather waste using it as ruminant feed. The wet blue leather wastes (WB) without chrome extraction were compared with the leather wastes in which the chrome was extracted (CE). Both materials had 99.7% of dry matter (DM), but the crude protein level was higher

9. Forage mass and the nutritive value of pastures mixed with forage peanut and red clover
The objective of this research was to estimate three pasture-based systems mixed with elephantgrass + spontaneous growth species, annual ryegrass, for pasture-based system 1; elephantgrass + spontaneous growth species + forage peanut, for pasture-based system 2; and elephantgrass + spontaneous growth species + annual ryegrass + red clover, for pasture-based

10. Chemical composition and ruminal degradation kinetics of crude protein and amino acids, and intestinal digestibility of amino acids from tropical forages
The objective of this research was to determine the chemical composition and ruminal degradation of the crude protein (CP), total and individual amino acids of leaves from tropical forages: perennial soybean (Neonotonia wightii), cassava (Manihot esculenta), leucaena (Leucaena leucocephala) and ramie (Boehmeria nivea), and to estimate the intestinal digestib

11. PRODUTIVIDADE E COMPOSIÇÃO QUÍMICA DE FORRAGEM DE AMENDOIM FORRAGEIRO E TREVO VERMELHO CONSORCIADOS COM GRAMÍNEAS / PRODUCTIVITY AND CHEMICAL COMPOSITION OF FORAGE PEANUT AND RED CLOVER MIXED WITH DIFFERENT GRASSES
O objetivo desta pesquisa foi avaliar três sistemas forrageiros (SF) com capim elefante (CE), espécies de crescimento espontâneo (ECE), azevém anual (AZ), como SF1; CE + ECE + AZ + amendoim forrageiro (AF), como SF2; e CE + ECE + AZ + trevo vermelho (TV), como SF3. O capim elefante foi estabelecido em linhas afastadas a cada 4 m. No período hibernal fez

12. Caracterização de leguminosas arbustivo-arbóreas em Pernambuco.
Experiments investigating the characteristics of forage legume were carried out in 2007 and 2008 at the Experimental Station in Itambe and São Bento do Una, both belonging to the State of Pernambuco Institute Agricultural Research Corporation, Brazil (IPA). The first experiment set out to characterize the morphology and quality of three plantations, each co
