【摘要】 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。更多还原

【Abstract】 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.更多还原
