Replacement of dicalcium phosphate by rock phosphate in cattle diets: nutrients digestibility, plasma parameters, ruminal fermentation and microbial synthesis efficiency
(Sociedade Brasileira de Zootecnia, 2010-04-01)
Este estudo foi conduzido para avaliar os efeitos da substituição do fosfato bicálcico pelo fosfato de rocha na dieta de bovinos em crescimento. Foram determinados a digestibilidade aparente das dietas, a absorção aparente ...
Metabolism and ruminal parameters of Holstein × Gir heifers fed sugarcane and increasing levels of crude protein
(Sociedade Brasileira de Zootecnia, 2012-09-01)
The objective of this study was to evaluate the effect of increasing levels of crude protein (CP) in the diet (13, 15, 19 and 22 g/100 g of dry matter, DM) on the metabolism and ruminal parameters of crossbred heifers fed ...
Metabolism and ruminal parameters of holstein × gir heifers fed sugarcane and increasing levels of crude protein
(2012-12-01)
The objective of this study was to evaluate the effect of increasing levels of crude protein (CP) in the diet (13, 15, 19 and 22 g/100 g of dry matter, DM) on the metabolism and ruminal parameters of crossbred heifers fed ...
Effects of feeding corn silage inoculated with microbial additives on the ruminal fermentation, microbial protein yield, and growth performance of lambs
(Amer Soc Animal Science, 2014-12-01)
This study aimed to examine the effects of feeding corn silage inoculated without or with either Lactobacillus buchneri (LB) alone or a combination of LB and Lactobacillus plantarum (LBLP) on the apparent digestibility, ...
Different true-protein sources do not modify the metabolism of crossbred Bos taurus x Bos indicus growing heifers
(Revista Brasileira Zootecnia Brazilian Journal Animal Sci, 2015-02-01)
The present study was conducted to investigate the effect of alternative true-protein sources to soybean meal, with different ruminal degradability, using a sugarcane-based diet, on nutrient digestion, ruminal fermentation, ...
Inoculation of corn silage with Lactobacillus plantarum and Bacillus subtilis associated with amylolytic enzyme supply at feeding. 1. Feed intake, apparent digestibility, and microbial protein synthesis in wethers
(2018-09-01)
The current study aimed to investigate the effects of corn silage inoculation and dietary supplementation with amylolytic enzymes, and their interactions, on feed intake, apparent digestibility, and microbial protein ...
The effect of lipid sources on intake, rumen fermentation parameters and microbial protein synthesis in Nellore steers supplemented with glycerol
(Csiro Publishing, 2014-01-01)
The effects of glycerol with fat sources as a feed alternative were investigated in the ration for Nellore steers (Bos indicus). Eight cannulated steers at 30 months of age with initial bodyweight of 554 +/- 36.0 kg were ...
Effect of lipid sources with different fatty acid profiles on intake, nutrient digestion and ruminal fermentation of feedlot Nellore steers
(2015-01-01)
The present study was conducted to determine the effect of lipid sources with different fatty acid profiles on nutrient digestion and ruminal fermentation. Ten rumen and duodenal fistulated Nellore steers (268 body weight±27 ...
Cinética digestiva e eficiência de síntese de proteína microbiana em novilhos alimentados com farelo de girassol e diferentes fontes energéticas
(Sociedade Brasileira de Zootecnia, 2006-02-01)
Objetivou-se avaliar o efeito da substituição parcial do milho pela casca de soja e pelo farelo de gérmen de milho sobre a produção e eficiência de síntese de proteína microbiana e sobre as taxas de diluição e passagem ...
Metabolizable Protein: 1. Predicting Equations to Estimate Microbial Crude Protein Synthesis in Small Ruminants
(2021-06-10)
Microbial crude protein (MCP) produced in rumen could be estimated by a variety of protocols of experimental sampling and analysis. However, a model to estimate this value is necessary when protein requirements are calculated ...
