日粮添加硒对热应激条件下蛋鸡血清抗氧化性能的影响
Effects of selenium amount added to ration on antioxidant properties in serum of laying hens under heat stress
摘要
Abstract
The laying hens were fed a corn-based basal diet(TN group)or the basal diet supplemented with 0(HS),0.3(HS +0.3),0.5 (HS +0.5)and 0.7 (HS +0.7)mg?kg Se.Serum free radicals,total superoxide dismutase(T-SOD)activity,glutathione peroxidase(GSH-Px)activity,and MDA content of laying hens were de-termined on 0,1,7,14 and 21 d post-heat stress.The results showed,heat stress group serum superoxide anion (OH)reduced to (97.33 ±1.48)U?L at the 7th day,heat stress reduced the ability of scavenging superoxide anion and hydroxyl radical inhibition in serum.Dietary Se supplementation increased the ability of scavenging su-peroxide anion and hydroxyl radical inhibition in serum.T-SOD increased to (83.78 ±0.96)U?mL of 0.7 mg?kg group at the 1st day,and GSH-Px increased to (489.26 ±9.97)U?mL of 0.7 mg?kg group at the 1st day.Heat stress caused some oxidative stress in laying hens,reduced its antioxidant capacity,but adding a certain amount of Se in the diet could improve the antioxidant ability of laying hens.关键词
