The study was conducted to evaluate effects of sodium monensin, Saccharomyces cerevisiae and a mixture of both, in cattle diets, on ruminal pH and ammonia concentration, partial and total nutrient digestibility, and microbial protein synthesis in the rumen. Four Holstein steers weighting 320 kg and cannulated in the rumen were used. A 4 × 4 Latin square experimental design was used and treatments consisted of daily intake of: 200 mg of sodium monensin (100I); 100 mg of sodium monensin + […]

It was aimed to study the efficiency of microbial synthesis and ruminal parameters in bovine. It were used five 165 kg growing no-castrated Nellore bulls, rumen, abomasum and ileum fistulated.A randomized blocks design with four treatments and five collection periods was used. The treatments consisted of four concentrate levels (20, 40, 60 and 80%). The roughage used was Tifton 85′ (Cynodon dactylon (L.) Pers.) Bermudagrass hay. The diets were isonitrogen with 15% of crude protein. The microbial marker used was […]
