The Effect of Raising Manner on The Moscovy Duck's Breeding Performance

通过不同饲养方式对番鸭产蛋后期繁殖性能影响的观测,结果表明:网上竹栅平养平均产蛋率(37.25%)显著高于地面平养(33.15%)(P<0.05);网上平养种蛋合格率(95.43%)和地面平养(95.34%)差异不显著(P>0.05);而地面平养受精率(96.28%)极显著高于网上平养(83.56%)(P<0.01);地面和网上平养存活率分别为99.96%和100%,差异不显著(P>0.05)。经比较分析,采用网上平养可提高饲养效益。

By observing the raising manner how influence the moscovy ducks＇ breeding performance, we can discover the average laying rate from the ducks which are raised on the mash（37.25% ）is higher than the data which comes from the ducks raised on the ground（33.15%） （P 〈0.05） .There are no significant difference in the egg eligibility and livability,which is 95.43% ,95.34% ,100% ,99.96% respectively.The ground raising＇ s fertility（96,28 % ）is significantly higher than the mesh raising＇s（ 83.56 % ）（ P 〈 0.01 ）. The results showed that Muscovy duck raised on mash had higher feeding benefits.
