Effects of Earthworm Hydrolysate on Growth Performance,Serum Biochemical,Antioxidant,and Immune Indices of Laying Hens Aged 13 to 18 Weeks
摘要
Abstract
[Objective]To study the effects of earthworm hydrolysate on growth performance,serum biochemical,antioxidant,and immune indices of laying hens.[Method]A total of 432 healthy 12-weeks old Hy-line Pink laying hens with similar body weight were randomly divided into 4 groups with 6 replicates per group and 18 hens per replicate.Hens in control group were fed a basal diet,and hens in experimental groups were fed a basal diet supplemented with 1％,2％and 3％earthworm hydrolysate,respectively.The experiment lasted for 6 weeks.During the experiment period,daily feed intake was recorded daily and weighted at 13th and 18th weeks old.At 18th weeks old six laying hens from each replicate were randomly selected to collect serum for the determination of serum biochemical indices,antioxidant indices and immune indices.[Result]Compared with the control group,①The differences in the growth performance indexes of laying hens of each test group were not significant(P＞0.05).②Diets supplemented with 1％and 3％earthworm hydrolysate significantly decreased the serum albumin/globulin(A/G)(P＜0.05),and significantly increased the level of total protein(TP)of laying hens(P＜0.05).Supplemented with 3％earthworm hydrolysate significantly increased the level of globulin(GLB)of laying hens(P＜0.05).③Diet supplemented with 1％,2％,and 3％earthworm hydrolysate extremely significantly increased the activities of serum total antioxidant capacity(T-AOC),superoxide dismutase(SOD)and glutathione peroxidase(GSH-Px)of laying hens(P＜0.01).Supplemented with 1％earthworm hydrolysate significantly decreased the level of serum malondialdehyde(MDA)level of laying hens(P＜0.01).④ Diet supplemented with 1％earthworm hydrolysate extremely increased the level of serum immunoglobulin G(IgG)(P＜0.01),and significantly increased the level of serum IgM of laying hens(P＜0.05).Supplemented with 1％,2％,and 3％earthworm hydrolysate significantly decreased the levels of serum interleukin-2(IL-2)and IL-6 of laying hens(P＜0.01).Supplemented with 1％earthworm hydrolysate significantly decreased the levels of serum IL-17 of laying hens(P＜0.01).Supplemented with 1％and 2％earthworm hydrolysate significantly decreased the level of serum tumor necrosis factor α(TNF-α)of laying hens(P＜0.01).[Conclusion]On the basis of without affecting growth performance,diet supplemented with earthworm hydrolysate could enhance antioxidant capacity and immune function of laying hens,and the optimum dosage was 1％.关键词
