摘 要:试验旨在评估日粮添加不同铜源对肉鸭生长性能、屠宰性能和粪便铜含量的影响。选取1056只1日龄樱桃谷肉鸭,分为硫酸铜组、蛋氨酸螯合铜组2个处理组,每个处理4个重复,每个重复132只。结果显示:在生长性能方面,饲粮中添加不同铜源对肉鸭各阶段日采食量、日增重和出栏体重影响不显著(P>0.05)。全期来看,添加蛋氨酸螯合铜组肉鸭1~38日龄料重比显著改善(P<0.05)。在屠宰性能方面,不同铜源对肉鸭各胴体指标均影响不显著(P>0.05)。蛋氨酸螯合铜组肉鸭粪便中铜含量比硫酸铜组高0.8mg/kg,但差异不显著(P>0.05)。综上,除料重比外,日粮添加不同铜源对肉鸭生长性能、粪铜含量影响无显著差异。This experiment was conducted to evaluate the effects of dietary copper on growth performance, carcass traits, and copper content in feces of meat ducks. A total of 1 056 one-day-age Cherry Valley duck were selected and randomly divided into 2 groups (group copper sulfate vs group methionine chelated copper) with 4 replicates in each group and 132 ducks in each replicate.The results showed that:①As for growth performance, dietary copper supplementation had no significant effect on ADFI, ADG and BW(P>0.05).The FCR in the group added methionine chelated copper significantly decreased (P<0.05).② There was no significant difference in carcass traits among different copper source ducks (P>0.05). The content of copper in feces of the methionine chelated copper group was 0.8 mg/kg higher than that of the copper sulfate group, but the difference was not significant(P>0.05).In conclusion, dietary copper supplementation had no significant effect on growth performance and fecal copper content of meat ducks, except for FCR.
