蛋氨酸羟基类似物对肉鸡肠道氧化还原状态的影响
Effect of 2-hydroxy-4-(methylthio) butanoic acid on intestinal redox state of broiler chickens
摘要
Abstract
Objective :To research the effects of methionine sources methionine ( DLM ), 2- hydroxy-4- (methylthio) butanoic acid (HMTBA) and 2-hydroxy-4- (methylthio) butyrate calcium (HMTBA-Ca) on intestinal redox state of broiler chickens.Method : One hundred and five ( 105 ) broiler chickens (44g) were randomly divided into 7 groups (15 birds per group) ,and each group was assigned to 1 of 3 treatments.Birds in each group were kept in three coops(5 broilers per coop).AII broilers were offered the same basal diet with added DLM,HMTBA and HMTBA- Ca at levels of 0 (control group), 0.1% and 0.2%. Results: Compared with control group, basal diet with 0.1% HMTBA group and 0.1% HMTBA-Ca group could decrease the level of free radicals in whole blood significantly, enhance the activity of GSH/GSSG, T-AOC of the serum and tissues significantly, decrease the level of MDA significantly.Compared with control group,basal diet with 0.2% HMTBA group and 0.2% HMTBA-Ca group could enhance the activity of CAT of the serum and tissues significantly.Basal diet with added HMTBA, HMTBA-Ca could enhance the intestinal villus height(V)and the ratio of the villus height to recess depth of broilers(V/C) ,decrease the intestinal recess depth (C)of broilers significantly.Compared with 0.1% DLM group, ROS, MDA levels were lower and V,V/C were higher in basal diet with 0.1% HMTBA group and 0.1% HMTBA-Ca group.Conclusion: Compared with DLM, HMTBA and HMTBA-Ca could better increase the intestinal antioxidative capacity,decrease the level of free radicals,steady intestinal redox state, promote the intestinal development healthily.关键词
