Abstract：The experiment was to investigate the effect of different levels of fermented soybean meal in diets of gestation and lactation sows on production performance of sows and antioxidant capacity of piglets.Sixty healthy'Landrace×Yorkshire'sows with body weight of(120±15)kg were randomly divided into four groups,with five replicates in each group.Sows in control group were fed with basic diet,and sows in treatment group were fed 4%,8%and 12%fermented soybean meal instead of common soybean meal in the basic diet,respectively.The experimental period was divided into two stages:Pregnancy(114 d)and lactation(28 d).The results showed that compared with control group,the average weaning litter weight and weaning litter gain of piglets in fermented soybean meal treatment group were extremely increased(P＜0.01),the feed intake of sows in fermented soybean meal treatment group was increased,and the feed cost of sows in 12%treatment group was extremely increased(P＜0.01).The feed cost of weaning litter with weight gain was significantly decreased(P＜0.05).The serum SOD activity of piglets in 12%treatment group was significantly higher than that in other treatment groups(P＜0.05),and GSH-Px and T-AOC of piglets in 12%treatment group were significantly higher than those in control group(P＜0.05).The study indicates that 12%fermented soybean meal can improve the production performance of sows,increase the antioxidant capacity of piglets,and reduce the feed cost.
