Effect of probiotic containing heat resistance Bacillus spores on the growth and some intestinal bacteria number of post-weaning piglets

Abstract

Effects of Bacillus Weaner (BW) containing Bacillus spores on growth and some intestinal bacteria number of the post-weaning piglets were assessed in this study. The studied result showed that BW did not affect the growth of pig, but reduced FCR, rate and duration of diarrhea. In addition, when feeding the piglets with BW supplemented diet, BW did not make the change of Clostridium perfringens and Escherichia coli numbers in duodenum, jejunum, cecum, colon and rectum of the piglets, but Lactobacillus number and total aerobic bacteria were increased in duodenum, jejunum, colon of the piglets. The result of this study can be considered as supportive evidences for supplementing BW in feed for the post-weaning piglets.
