Abstract


The objective of this work was to evaluate the effects of Saccharomices cerevisiae and Lactobacillus casei in bovine diets, on dry matter (DM), organic matter (OM), crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber (ADF) intake and digestibility, ruminal pH and ammonia nitrogen (N-NH3) and plasma urea nitrogen (PUN). Rations were isoproteic (13,04% CP) and isoenergetic (66,39% TDN) with sorghum silage used as roughage (50% of DM). Six ruminal-cannulated males, castrated, ½Gir½ Holstein crossbred, with average live wight of 317 kg and 24 months old were utilized. Treatments were determined as control (without probiotic addition) and with probiotic, which contained 4,5 x 109 CFU/animal/day of Saccaromyces cerevisiae and 3,1 x 107 CFU/animal/day of Lactobacillus casei. The experiment lasted 38 days, divided in two periods of 19 days. In the present work, the supply of live yeast Saccharomyces Cerevisiae and lactic bacteria Lactobacillus casei had no influence on DM, OM, CP, NDF and ADF intake and digestibility, ruminal pH, ruminal N-NH3 and PUN, indicating that can be used in cattle feed when necessary.
