Lactobacillus sporogenes was isolated by NAKAYAMA et al. (1949) and kindly supplied by them to Sankyo Company. Experiments were conducted to determine the promotion of L. sporogenes and its biological responses for chickens were observed. Day-old single comb White Leghorn cockerels obtained from a commercial hatchery were reared in electrically-heated, metal wire floored battery brooders. The ten birds each were used in experimental and control groups, and trials were repeated seven times. The preparations containing 1×109 spores of L. sporogenes per gram was fed to chickens at the dietary level of 100ppm for 4 weeks. The results were as follows; L. sporogenes caused an increase of weight gain and an improvement of feed efficiency in chickens fed for 4 weeks. The vegetative cells and spores of L. sporogenes were recovered from and the amount of lactic acid increased in the small intestine and caecum when chicken were fed the organisms. However, the pH of intestinal contents, and the amount of serum cholesterol and serum lactic acid were not significantly different from control values.
