Two of the strains, B amilolyquifaciens and B pumilus, in the Microsaf probiotic mix indeed have bile salt hydrolase activity. With respect to your question, if presence of this activity would influence broiler production yield when feeding a diet with acid, we speculate that this is not the case like for the lactobacilli having this activity. The bacilli in the Microsaft mix are all treated with ...
