Effects of new fermented soybean meal on growth performance and development of gastrointestinal tract in weaned pglets

This experiment was conducted to study the effect of special fermented soybean meal on growth performance and the development of gastrointestinal tract in weaned piglets.Ninty weaned piglets(Duroc×FengJing×JangQuHai) weighing an average of(4.75±0.38) kg at 26 days age were randomly assigned into two treatment groups with three replicates and 10 piglets with each pen,according to litter and body weight.Piglets in treatmentⅠwere fed with 17.5 percent of special fermented soybean meal and with 35 percent in treatment Ⅱ.The result showed that there were significant effects on percentage of daily gains,percentage of diarrhea rate,gastric contents pH,gastric mucosal thickness and gastric wall thickness in two treatment groups.The feed/ weight of two treatments decreased by 4.21% and 19.47% in treatment Ⅱ(P0.01).The Villus height Cript depth gastric and wall thickness increased significantly in treatments.Besize,that in treatmentⅠhad also an improvement.These results indicated that special fermented soybean meal could improve growth performance of weaned piglet,decrease diarrhea rate and improve the development of gastrointestinal tract significantly.
