The objective of this study was to evaluate the effect of monensin, yeast complex, unsaturated fatty acids and amino acids on dry matter and nutrient intake, total and partial digestibility and ruminal parameters of ruminal fermentation (pH, ammonia nitrogen concentration and short chain fatty acids), the protozoa population and methane production. Six castrated steers, body weight 530 ± 15 kg were used, receiving yeast complex, polyunsaturated fatty acids and amino acids (5 g/dia), monensin (5 g/dia), caulim (5g/dia, used as […]
