不同饲养模式对蛋鸭生产性能的影响

Effect of different feeding modes on the production performance of laying ducks

本试验研究全封闭式、半封闭式两种饲养模式对莆田黑鸭生产性能的影响。结果显示两种饲养模式下,莆田黑鸭开产日龄、300日龄产蛋数和平均蛋重差异均不显著(P>0.05);半封闭饲养模式下300日龄鸭胫长显著长于全封闭式饲养模式(P<0.05),其它体尺指标差异均不显著(P>0.05)。结果说明,封闭式饲养模式可以替代传统的蛋鸭半封闭饲养模式。

The effects of different feeding modes including closed,semi-closed on the production performance of laying ducks were studied in this experiment.The results showed that there were no significant difference between two feeding modes of laying ducks in first laying age,egg production and average egg weight of the 300 day-old(P>0.05).The shank length of the 300 day-old in semi-closed feeding modes was significantly longer than closed feeding modes(P<0.05),and there were no significant difference in other body size(P>0.05).The result indicate that closed feeding mode can instead the traditional semi-closed feeding mode of laying ducks.
