Effects of yeast-Se on serum enzyme activity and antioxidant capacity of laying hens
The experiment was conducted to study the effect of yeast-Se on serum enzyme activity and antioxidant capacity of laying hens.One thousand 280-day-old laying hens were randomly divided into 5 groups with 5 replications of 40 layers each.The control group was fed with the cornsoybean meal based diets,and other experimental groups was fed with the basic diets added with 0.1,0.2,0.3 and 0.4 mg/kg yeast-Se,respectively.The results showed that all experiment groups significantly increased the activity of ALP and LDH (P＜0.05),meanwhile decrease the activity of CK (P＜0.05);The activity of SOD in experimental groups added with 0.2 and 0.4 mg/kg yeastSe were significantly higher than that of the control group (P＜0.05),and the activity of GSH-Px and T-AOC in all the experimental groups were significantly increased (P＜0.05),the MDA level of all the groups added with yeast-Se were significantly lower than that of the control group.These results indicated that yeast-Se can increase serum antioxidant capacity of laying hens,and 0.3,0.4 mg/kg Yeast-Se may be optimal levels in diet for laying hens.
