The aim of this study was to investigate the efficacy of Lactobacillus spp. W44 and J124 strain isolated from Kimchi on the growth rate, average daily gain (ADG), feed conversion and change of intestine microflora in the weaning piglets. In the experiment 1, growth rate was significantly increased to and after oral administration of W44 and J124 strain as feed additives, respectively (p<0.05). ADG and feed conversion were also significantly improved after administration during 44 experiment days (p<0.05). In the analysis of intestinal microflora, the number of Lactobacillus spp. in the experiment groups was significantly increased 100 to 1,000 times compared to those of control group. In the experiment 2, the efficacy of W44 and J124 strains on the growth rate, ADG, feed conversion and change of intestine microflora were reconfirmed significantly (p<0.05). However, there were no significant differences on feed conversion in the W44 bead and J124 bead groups. In summary, our results suggest that W-44 and J-124 stains from Kimchi have a significant effect on the weight gain and feed conversion, and it may be useful probiotic strains for the weaning piglets as feed additives.
