摘要：This study investigated the effect of Proenzime® probiotic added to protein-mineral mixture on the weight gain of cattle reared in extensive system on Brachiaria brizantha pasture. The 114 Nelore uncastrated male calves (Bos indicus) used, about 15 months of age, were randomly divided into 2 groups (57 animals each): the control group (GC) received only protein-mineral mixture while the probiotic group (PG) received this mixture supplemented with Proenzime® probiotic. The animals were weighted on days 0 and 150. The results indicate a significant increase in the weight gains of the PG calves. Considering the experimental conditions and the results obtained, it is concluded that the addition of Proenzime® probiotic to the proteinmineral mixture leads to increase in weight gain of cattle and thus higher economic feedback.
