摘要

本试验旨在研究饲粮锌水平对肉鸡生长性能、屠宰性能、血清免疫指标及锌排放的影响。选择1日龄健康爱拔益加（AA）肉鸡600只，随机分为5个组，每组6个重复，每个重复20只鸡（公母各占1/2）。各组饲粮锌水平分别为30（基础饲粮组）、60、90、120、150 mg/kg。试验期42 d。结果表明：1）1~42日龄，60、90、120和150 mg/kg锌水平组公鸡的平均日增重显著高于基础饲粮组（P<0.05），各组母鸡的平均日增重差异不显著（P>0.05）。2）饲粮锌水平对21和42日龄肉鸡免疫器官指数和屠宰性能均无显著影响（P>0.05）。3）公鸡21日龄时，120、150 mg/kg锌水平组的新城疫血清抗体滴度显著高于基础饲粮组和60、90 mg/kg锌水平组（P<0.05）；42日龄时，各组之间新城疫血清抗体滴度差异不显著（P>0.05）。母鸡21日龄时，各组之间新城疫血清抗体滴度差异不显著（P>0.05）；42日龄时，120 mg/kg锌水平组新城疫血清抗体滴度显著高于其他各组（P<0.05）。4）饲粮锌水平对21和42日龄肉鸡粪便锌含量和锌表观利用率有显著影响（P<0.05）。在不同生长阶段，42日龄的粪便锌含量明显高于21日龄，21日龄的锌表观利用率明显高于42日龄。由此可见，在本试验条件下，饲粮锌水平为60 mg/kg时能满足肉鸡生长的需要，饲粮的锌水平为120 mg/kg时能够保持肉鸡较好的免疫功能。

Abstract

This experiment was conducted to investigate the effects of dietary zinc level on growth performance, slaughter performance, serum immune indexes and zinc emissions of broilers. A total of 600 healthy one-day-old Arbor Acres (AA) broilers were randomly allocated into 5 groups with 6 replicates per group and 20 broilers per replicate. Dietary zinc levels of all groups were 30 (basal diet group), 60, 90, 120 and 150 mg/kg, respectively. The experiment lasted for 42 days. The results showed as follows:1) during 1 to 42 days of age, the average daily gain of male broilers in 60, 90, 120 and 150 mg/kg zinc level groups was significantly higher than that in the basal diet group (P<0.05), but no significant difference was observed on the average daily gain of female broilers among all groups (P>0.05). 2) Dietary zinc level had no significant influence on immune organ index and slaughter performance of broilers at 21 and 42 days of age (P>0.05). 3) For male broilers at 21 days of age, the newcastle disease serum antibody titer in 120 and 150 mg/kg zinc level groups was significantly higher than that in the basal diet group and 60, 90 mg/kg zinc level groups (P<0.05), and at 21 days of age, no significant difference was observed in the newcastle disease serum antibody titer among all groups (P>0.05). For female broilers at 21 days of age, no significant difference was observed in the newcastle disease serum antibody titer among all groups (P>0.05), and at 42 days of age, the newcastle disease serum antibody titer in 120 mg/kg zinc level group was significantly higher than that in other groups (P<0.05). 4) Dietary zinc level had significant influence on the fecal zinc content and zinc apparent utilization rate of broilers at 21 and 42 days of age (P<0.05). At different growth stages, the fecal zinc content at 42 days of age was obviously higher than that at 21 days of age, the zinc apparent utilization rate at 21 days of age was obviously higher than that at 42 days of age. In conclusion, under this experimental condition, when dietary zinc level is 60 mg/kg, it can meet the needs of broiler growth; when dietary zinc level is 120 mg/kg, it can maintain the immune function of broilers.
