Effects of Different Feed Additives on Egg Quality and Reproductive Performance of Yellow-feathered Broilers
摘要
Abstract
In this experiment,360 healthy 140-day-old yellow-feathered broiler chickens with no significant weight differences were randomly selected and split into 4 groups,each with 3 replicates of 30 birds.Groups 1,2,and 3 served as experimental groups,which were supplemented with 0.025％Enzyme Yikang,0.025％Tianliwei,and 0.025％Chinese herbal extract in their diets,respectively.Group 4 acted as the control group,fed the basal diet.Egg quality tests were performed every 4 weeks throughout the trial period.In the 9th week,chickens in all groups received multiple artificial inseminations.The breeding eggs produced post-insemination were collected for centralized hatchability trials,and data such as hatch rates were recorded.The results indicated:Group 1 eggs showed significantly higher weight than Group 3(P＜0.05),but no significant difference compared to Group 2 or the control group(P＞0.05).The egg white height in Group 2 was significantly higher than that in Group 1(P＜0.05),but no significant difference was observed compared to Group 3 or the Control group(P＞0.05).The egg yolk weight in Group 1 was significantly higher than that in Group 2(P＜0.05),but no significant difference was observed compared to Group 3 or the Control group(P＞0.05).The a*value(redness)of eggshells in Group 1,Group 2,and the Control Group showed no significant difference(P＞0.05),but were significantly higher than that in Group 3(P＜0.05).The L*value(lightness)of egg yolks in Group 2 and the Control Group was significantly higher than that in Group 3(P＜0.05).The a*value(redness)of egg yolks in Group 1 was significantly higher than that in the other three groups(P＜0.05).The calcium content in eggs from the Control group was significantly higher than other groups(P＜0.05),while that in Group 3 was significantly lower than other groups(P＜0.05).The dead embryo rate in Group 2 was significantly lower than that in Group 3(P＜0.05),but showed no significant difference compared to the Group 1 and Control group(P＞0.05).The hatchability rate in Group 2 was significantly lower than the other three groups(P＜0.05).In summary,adding 0.025％enzyme Yikang to the diet can promote egg yolk weight and egg yolk redness a*.Adding 0.025％Tieliwei can increase the protein height and reduce the dead embryo rate.The addition of 0.025％Chinese herbal medicine extract promoted the strength of eggshell,but reduced the content of trace elements in eggs.All three feed additives had a certain degree of influence.关键词
