Enteromorpha prolifera Supplemental Level: Effects on Laying Performance, Egg Quality, Immune Function and Microflora in Feces of Laying Hens
摘要
Abstract
Effects of different supplemental levels of Enteromorpha prolifera on laying performance,egg quality,immune function,and microflora in feces of laying hens were studied in the present experiment.A total of ninety-six 42-week-old Highland brown laying hens with similar laying rate were randomly divided into 4 groups with 8 replicates per group and 6 birds per replicate.Hens were fed diets supplemented with 0 (control group),1 ％ (group 1),2 ％ (group 2) and 3 ％ Enteromorpha prolifera meal (group 3).The experiment lasted for 28 days.The results showed as follows:dietary supplementation of Enteromorpha prolifera did not have significant effects on laying rate and average daily feed intake (P ＞ 0.05),but Enteromorpha prolifera significantly increased average egg weight (P ＜ 0.05),and significantly decreased feed:egg (P ＜ 0.05).Shell thickness of group 3 was significantly higher than that of control group.Shell calcium content and yolk color of the groups supplemented with Enteromorpha prolifera were significantly improved compared with control group (P ＜ 0.05),but yolk cholesterol content was significantly reduced (P ＜ 0.05).Hens fed Enteromorpha prolifera-supplemented diets had higher serum antibody titers of Newcastle Disease and lymphocyte transformation rate of blood,and there were significant difference between groups 2 and 3 and control group (P ＜ 0.05).In groups 2 and 3,the number of Escherichia coli in feces was significantly reduced (P ＜ 0.01and P ＜ 0.05),while the number of Bifida bacterium in feces was significantly increased compared with control group (P ＜ 0.05 and P ＜ 0.01) ; in groups 1 and 2,the number of Lactobacillus bacterium was significantly increased compared with control group (P ＜ 0.01 and P ＜ 0.05).In conclusion,the supplementation of Enteromorpha prolifera up to 1％-3％ can improve laying performance,egg quality,immune function and microflora in feces of laying hens in different degrees.关键词
