The effects of dietary concentrate levels were evaluated on the microbial synthesis efficiency, the nitrogenous compounds balance, the ammonia concentrations and the ruminal fluid pH, the ruminal digesta passage rate and the endogenous losses of nitrogen compounds (N). Five F1 Simental x Nellore bulls fistulated in the rumen, abomasum and ileum, full fed diets with 25.0; 37.5; 50.0; 62.5; and 75.0% of concentrate and allotted to 5×5 Latin square, were used. The ammonia concentrations and the ruminal pH were determined […]

ABSTRACT – A trial was conducted to evaluate the effects of five concentrate levels in the diet on the efficiency of microbial synthesis, balance of nitrogen compounds, ammonia concentrate and pH ruminal fluid. Five rumen, abomasum and ileum fistulated F1 Limousin x Nellore bulls were full fed diets containing 25.0, 37.5, 50.0, 62.5, and 75.0% of concentrate and allotted to a 5 x 5 latin square design. The ammonia concentrations and ruminal pH were determined in ruminal fluid samples collected […]
