Effects of Alfalfa Saponins on Performance, Egg Quality and Antioxidant Capacity of Laying Hens
摘要
Abstract
This experiment was conducted to investigate the effect of alfalfa saponins on performance,egg quality and antioxidant capacity of laying hens.A total of 150 Hy-Line brown laying hens at 190-day-old were randomly divided into 5 groups with 5 replicates per group and 6 birds per replicate.Hens in the control group were fed a basal diet,and the others in the groups Ⅰ to Ⅳ were fed the basal diets supplemented with 60,120,240 and 480 mg/kg alfalfa saponins,respectively.The experiment lasted for 77 days.The results showed as follows:1) the average daily feed intake and ratio of feed to egg of group Ⅱ were significantly lower than that of control group (P<0.05),the egg weight of groups Ⅱ and Ⅲ was significantly lower than that of control group (P<0.05),there were no significant differences on laying rate among all groups (P>0.05).2) At the 30th day,the egg yolk color of group Ⅳ was significantly lower than that of control group (P<0.05);at the 45th day,the egg yolk color of groups Ⅱ and Ⅲ was significantly lower than that of control group (P<0.05);at the 60th day,the egg yolk color of groups Ⅰ,Ⅱ,Ⅲ and Ⅳ was significantly lower than that of control group (P<0.05).3) The glutathione peroxidase and superoxide dismutase activity and malondialdehyde content in liver,breast muscle and leg muscle of groups Ⅰ,Ⅱ,Ⅲ and Ⅳ had no significant difference compared with the control group (P>0.05).Comprehensive analysis of all indices,under the condition of this experiment,dietary suitable alfalfa saponins supplemental level is 120 mg/kg.关键词
