1. Red clover silage: an alternative for mitigating the impact of nitrogen excretion in ovine production systems
ABSTRACT The objective was to quantify the flow of intestinal nutrients and nitrogen excretion and retention in sheep receiving isoproteic diets. Eight Texel x Lacaune wethers (average body weight = 25±2.5 kg) were fitted with duodenal cannula and housed in metabolic cages. Wethers were assigned to the treatments in a crossover design with two periods of 20

2. Kinetics of digestion of low-quality forage grazed by beef cattle fed supplements containing increasing levels of rumen undegradable protein
ABSTRACT This experiment was conducted to evaluate the degradation kinetics and microbial efficiency of beef cattle grazing on low-quality forage and receiving supplements with different levels of rumen undegradable protein (RUP). The animals grazed on palisade grass pasture solely or this pasture and supplement containing 40 or 60 g of RUP per 100 g of crud

3. Performance and metabolite profile of dairy cows fed tropical grasses and concentrates containing crude protein with low or high degradability
ABSTRACT Ten Holstein-Zebu crossbred cows distributed into two simultaneous Latin squares (5 × 5) as a 2 × 2 factorial arrangement formed by chopped sugarcane or elephant grass silage, both with high or low protein degradability supplements and a corn silage as a control treatment, were compared using orthogonal contrasts. The studied variables were the pe

4. Editorial
Diets formulated with protein sources presenting different resistance to ruminal degradation were compared by evaluating ruminal parameters, production and microbial efficiency and nutrients flow to the omasum in goats. Eight rumen cannulated non-lactating, non-pregnant goats were distributed in a 4 × 4 Latin square design with two replicates. Treatments co

5. 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

6. Branched-chain amino acids in cattle nutrition / Ácidos graxos voláteis de cadeia ramificada na nutrição de bovinos
Pasture is the main source of cattle feed, but it is not capable of supplying the animal nutritional requirements completely. Therefore, an adequate management is necessary to improve productivity and reduce costs related to long term production. The search for technology to increase animal performance may be a feasible alternative to reduce costs with cattl

7. Levels of concentrate and rumen undegradable protein in the diet of lactating cows / Níveis de concentrado e de proteína não degradável no rúmen na dieta de vacas em lactação
The modern consumer increasingly choose quality products, and industry, seeking to adapt to this new trend, has sought to reward the producer by milk quality, especially with regard to its total solids composition. This way, an experiment was conducted at the Dairy Cattle Teaching, Research and Extension Unit of Animal Science Department of Universidade Fede

8. NUTRITIVE VALUE OF DIETS BASED ON FRESH RYEGRASS (Lolium multiflorum, LAM.) FORAGE SUPPLEMENTED WITH NITROGEN OR ENERGY / VALOR ALIMENTAR DE DIETAS COM AZEVÉM (Lolium multiflorum, LAM.) E SUPLEMENTAÇÃO NITROGENADA OU ENERGÉTICA
The present study was carried out to determine the effects of supplementing fresh ryegrass forage based diets with starch, rumen degradable or undegradable protein sources on intake, digestion and nitrogen retention, rumen digestibility and the duodenal nitrogen flow. Ten Corriedale lambs (26 kg mean body weight), kept in metabolic cages were used in a 5 x 5

9. Digestibilidade total e parcial e fluxo de nutrientes em cabras leiteiras alimentadas com diferentes fontes protéicas / Total and partial digestibility and fluxes of nutrients in dairy goats fed with different sources of proteins
Diets formulated with protein sources presenting different resistance to ruminal degradation were compared by evaluating intake, total and partial digestibility, nitrogen balance, fluxes of nutrients to omasum, production and microbial efficiency and ruminal parameters in goats. Eight rumen cannulated non-lactating, non- pregnant goats were distributed in a

10. Intake, digestibility, and rumen dynamics in cattle fed low-quality tropical forage and supplemented with nitrogenous compounds / Consumo, digestibilidade e dinâmica ruminal em bovinos alimentados com forragem tropical de baixa qualidade suplementados com compostos nitrogenados
The aim of this work was to evaluate the effects of supplementation with nitrogenous compounds on intake, digestibility, nitrogenous compounds balance, efficiency of microbial synthesis, and neutral detergent fiber (NDF) rumen dynamics in cattle fed low-quality forage. Five crossbred heifers, with average live weight of 191 kg and fitted with rumen canullae,

11. In vitro degradation dynamics of neutral detergent fiber of signal grass according to supplementation with different sources of nitrogenous compounds and carbohydrates / Dinâmica de degradação in vitro da fibra em detergente neutro de capim-braquiária em função de suplementação com diferentes fontes de compostos nitrogenados e carboidratos
Two experiments were carried out to evaluate the utilization of fibrous carbohydrates from high quality grass by ruminal microorganisms. In the first experiment, it was studied the degradation dynamics of neutral detergent fiber (NDF) from high quality signal grass (Brachiaria decumbens Stapf.) according to supplementation with different sources of carbohydr

12. Dinâmica de degradação in vitro da fibra em detergente neutro de forragens tropicais em função de suplementação protéica e/ou energética / In vitro degradation dynamics of tropical forages neutral detergent fiber according to protein and/or energy supplementation
The current thesis was based on two in vitro trials aiming at assessing the effect of protein and/or energy supplementation on ruminal degradation of fibrous carbohydrates of tropical forages. At Experiment 1, it was evaluated the effect of protein and/or energy supplementation on the utilization of fibrous carbohydrates from low quality forage by ruminal mi
