CLOSTAT™ Application in Poultry

Scientific trials showed a significant effect on the microflora (an increase of Lactobacilli and Bifidobacteria, reduction of Clostridiaceae and Enterobacteriaceae). Consecutively, the intestinal villi in jejunum and ileum of the animals that receive CLOSTAT in the feed are significantly longer than in the control animals.
