Effects of Different Dietary Zinc-Pectic Oligosaccharide Chelate Supplemental Levels on Growth Performance, Immune Function and Serum Antioxidant Capacity of Broilers
摘要
Abstract
This experiment was conducted to investigate the effects of different dietary zinc-pectic oligosaccharide chelate (Zn-POS) supplemental levels on growth performance,immune function and serum antioxidant capacity of Arbor Acre (AA) broilers.A total of 480 one-day-old AA broilers were randomly divided into 5 groups with 6 replicates per group and 16 chicks per replicate.Group Ⅰ was a basal diet group,group Ⅱ was the antibiotics group supplemented with 62.5 mg/kg flavomycin,and groups Ⅲ,Ⅳ and Ⅴ were Zn-POS groups,which supplemented with 300,600 and 900 mg/kg Zn-POS,respectively.The whole experiment lasted for 42 d.The results showed as follows:Ⅰ) from Ⅰ to 21 days of age,compared with group Ⅰ,the average daily gain was significantly increased in groups Ⅲ and Ⅳ (P＜0.05).Compared with group Ⅱ,the body weight in groups Ⅲ and Ⅳ was significantly increased (P＜0.05).From 22 to 42 days of age,compared with group Ⅰ,the average daily gain in groups Ⅲ and Ⅳ was significantly increased (P＜0.05),and the average daily feed intake in group Ⅳ was significantly increased (P＜0.05).From Ⅰ to 42 days of age,compared with group Ⅰ,the average daily gain in group Ⅳ was extremely significantly increased (P＜0.01),the average daily gain in groups Ⅲ and Ⅴ was significantly increased (P＜0.05),and the average daily feed intake in group Ⅳ was significantly increased (P＜0.05).The average daily gain in group Ⅱ was extremely significantly higher than that in group Ⅰ (P＜0.01).2) Compared with group Ⅰ,the bursa of Fabricius index in group Ⅱ was significantly improved (P＜0.05),but the serum immunoglobulin G (IgG) level in group Ⅱ was significantly decreased (P＜0.05).3) Compared with group Ⅰ,the serum total superoxide dismutase activity in group Ⅲ was significantly increased (P＜0.05),and the serum catalase activity in groups Ⅲ and Ⅴ was significantly increased (P＜0.05),too.Compared with group Ⅲ,the serum malondialdehyde content was significantly decreased in groups Ⅳ and Ⅴ (P＜0.05).In conclusion,dietary Zn-POS supplementation can improve the growth performance,immune function and serum antioxidant capacity of AA broilers from Ⅰ to 42 days of age,and the optimum supplemental level is 600 mg/kg.关键词
