| Abstract: | In order to explore the effects of chitosan on growth performance and anti-oxidative status in weanling pigs. Fifty weanling with 21 days old piglets were challenged with enterotoxigenic Escherichia coli during preliminary trial period and randomly assigned to five treatment groups fed respectively a maize-soybean meal diet containing either no addition, 50 mg/kg chlortetracyecline,200 mg/kg,300 mg/kg or 400 mg/kg chitosan for 21 days.The results showed as follows：Compared with the control group,1） daily feed intake was improved（P0.05）,the ratio of feed to gain and diarrhearate was decreased in every experimental group,average daily gains were increased respectively 15.8%,9.2%, 16.8%and 21.1%（P0.05）;2）the activity of GSH-Px（P0.05）,NOS（P0.05）,POD（P0.05）,T-SOD （P0.05） and the content of T-AOC（P0.01） were improved,and the concentrations of MDA（P0.01） and NO （P0.05） were decreased with different extent in three ehitosan groups.These results indicate that diet supplemented with 200 mg/kg,300 mg/kg and 400 mg/kg chilosan can improve growth performance,decrease diarrhea rate and enhance antioxidant capacity in weanling piglets. |
