AFB1降解剂对肉鸡生长性能、养分代谢及AFB1在体内残留的影响
Effect of AFB1-degrading Agent on Growth Performance, Nutrients Metabolism and AFB1 Residues in Broiler
摘要
Abstract
Effects of aflatoxin B1 (AFB1)-degrading agent on growth performance,nutrients metabolism and AFB1residues in blood,liver and muscles were studied by adding it in broiler diets infected AFB1.Seventy five 42-day-old Arbor Acres (AA) broilers were randomly allocated to 5 groups with 5 replicates per group.Broilers in group A (control group) were fed with basic diet,the diets of group B (negative control group),C,D and E were supplemented with 400,200,400 and 800 μg/kg AFB1,and broilers in group C,D and E were fed with the diets containing 0.15％ AFB1-degrading agent,respectively.The experiment lasted for 30 d.Growth performance,nutrient metabolic rate,AFB1 contents and antioxidant indices were measured at the and of experiment.The results indicated that,compared with group B,the final weight and average daily feed intake of group D were increased by 32.45％ and 42.46％ (P＜0.05),and the metabolic rates of organic matter,crude protein,calcium and phosphorus in other groups were significantly increased (P＜0.05),the metabolic rates of organic matter and crude protein in group D increased by 9.50％ and 178.75％(P＜0.05).Liver AFB1 content in group C was significant lower than that in group B (P＜0.05).The breast muscle AFB1 contents in group A and C were significant lower than that in other groups (P＜0.05) at 24 h after AFB1 administration termination.The breast muscle AFB1 contents in group C and D were similar to the control group at 48 h after AFB1 administration termination.Compared with group B,SOD,GSH-Px activities of serum and liver in group C,D and E were significantly increased (P＜0.05).It was concluded that adding AFB1-degrading agent in diets could increase broiler growth and nutrient availability,accelerate AFB1 metabolism,and reduce the harmful effect of AFB1 on broilers.关键词
