Probiotic effects of Lactobacillus reuteri BSA-131 on piglets = 자돈에 투여한 Lactobacillus reuteri BSA-131의 생균제 효과

Abstract

A study was carried out to determine the probiotic effect of Lactobacillus reuteri BSA-131 by investigating the growth performance and fecal microbial population of piglets. Five dietary treatment groups, the basal diet (control, BD), basal diet with antibiotics (BA), basal diet with 2 x 106/g of probiotics (BP6), 2 x 108/g of probiotic (BP8) and basal diet with antibiotics and 2 x 108/g probiotics (BAP8) were devised. Each dietary treatment group was consisted of 1 month of age piglets(male 13, female 12). Fecal microflora, body weights and feed consumption were measured at before, after and stop feeding of probiotics. The results showed that the CFU of fecal Enterobacteriaceae of piglets of the group BA, BP6, BP8 and BAP8, were reduced (P<0.05) compared to control BA. On the contrary, Lactobacillus counts were increased significantly (P<0.001) in all groups fed probiotics diets, but not antibiotics. Body weight of probiotics treated piglets were improved 5% (P<0.001) in BP6 group than that of control group and antibiotic treated piglets BAP group was 27% (p<0.001) greater weight gaining than BA group. The amount of feed consumption value of probiotics treated piglets showed 21-30% (P<0.001) lower intake than the control group, whereas antibiotic treated piglets BAP was 20% (P<0.001) higher than BA group. The results showed that body weights and feed to gain ratios were improved 19% when compared to control piglets for groups fed diets probiotic. It is very suggestive that productivity of probiotic piglets would be economical in pig farming.
