In this study ， mice were administered with probiotics cheese and collected the feces ， aimed to investigate the effects of probiotic icecream on intestinal microflora in mice. The results of the study showed that: the numbers of bacterias on the intestinal in mice that were administered with lactobacillus casei cheese ， lactobacillus plantarum cheese ， showed extremely significant difference （P0.01 ） to those in commercial starter culture cheese and normal saline as control group. Probiotic cheese could promote the intestinal bacteria in mice significant proliferation and have certain regula- tory role in
