摘  要:
选取荆江麻鸭90只,随机分为3组,对照组饲喂基础日粮、试验A组在日粮中添加氧化锌(80mg/kg)、试验B组在日粮中添加氨基酸螯合锌(80 mg/kg),比较不同锌源对荆江麻鸭产蛋性能的影响。试验结果表明,试验A组和试验B组平均蛋重与对照组比较无明显差异(P>0.05);第25天,试验B组鸭群产蛋率比对照组和试验A组分别提高18.17%和13.04%,试验B组较对照组和试验A组的料蛋比分别降低了0.20、0.12,差异显著(P<0.05)。由此可见,日粮中添加氨基酸螯合锌对蛋鸭的蛋重无显著影响,可显著提高产蛋率、降低料蛋比。在荆江麻鸭日粮中添加氨基酸螯合锌,可有效提高蛋鸭的产蛋性能。

摘  要:
90 Jingjiang patridge ducks were randomly allocated to 3 groups to investigate the effect of different zinc sources on egg production performance.The control group was fed with basal diet and experimental group A and B were supplemented with 80mg/kg zinc oxide(ZnO) and zinc-methionine(Zn-met),respectively.The results showed that there was no significant difference(P>0.05) in average egg weight among 3 groups.Compared with the control group and experimental group A,the laying rate and the feed egg ratio of experimental group B were in significant difference(P<0.05) at 25th day.The laying rate of experimental group B increased 18.17% and 13.04% respectively and the feed egg ratio of experimental group B decreased 0.20 and 0.12 respectively.It indicated that the laying performance of Jingjiang patridge ducks could be effectively improved by supplemented with Zn-met.
