영어 초록
This study was conducted to investigate effects of feeding fermented milk on growth, intestinal microorganisms and fecal noxious gas emission in suckling pigs. A total of a hundred birth piglets (Landrace×Yorkshire×Duroc) were randomly assigned into feeding group and control group during suckling period that ten pigs per sow. Fermented milk contained 3.0×108/g of Bacillus and 3.5×108/g of Lactobacillus, and was supplied by top dressing method. Fermented milk fed to the sulking pigs indicated tendency to increase weaning body weight (p=0.052) and average daily gain (p=0.094). Total microbial flora and Escherichia coli in the feces were lower (p<0.05) in the feeding group than the non-feeding group. Reversely, Lactobacillus was higher (p<0.01) in feces of the pigs fed fermented milk than the pigs of the control group. Hydrogen sulfide emitted in feces was decreased in feeding group compared with control group (p<0.05). Similarly, fecal total mercaptans was diminished in the feeding group than the control group (p<0.01). Therefore, the fermented milk fed to the sulking pigs may improved growth and can influence positively intestinal microorganisms and fecal noxious gas emission.
