In conclusion, from the results of this study it was shown that the addition of L. brevis ZLB004 could improve intestinal microflora balance, immunity and growth performance of weaned pigs; therefore, it may have the potential to be used as probiotic for weaned pigs. And further research is also needed to fully determine the optimal additive level and exact mechanisms through which the probiotic effect of L. brevis ZLB004 are realized.
