The Effect of Bacillus subtilis Formulations on Performance in Piglets

Test selection 16 wo duroc×landrace×big white 8-day-old grew up in three-way cross suckling piglets,according to birth date,litter size were randomly divided into four similar groups of four nests.The control group(Ⅰ) basic diet supple mented with 0.01% fed aureomycin,test group(Ⅱ,Ⅲ,Ⅳ) feeding basic diet supplemented with 0.01%,0.05% and 0.10% of Bacillus subtilis,Bacillus subtilis on the study production performance of piglets.The results showed that Bacillus subtilis test feeding pigs with chlortetracycline compared with the control group,piglet average daily gain significantly increased the incidence of diarrhea have been reduced,Bacillus subtilis aureomycin in each group were higher than the control group;Bacillus subtilis with 0.10% added as the best,but all groups were no significantly different(P 0.05).The conclusion of Bacillus subtilis on improving the production performance of piglets with good results,Bacillus subtilis was fully capable of an alternative feed chlortetracycline.
