不同饲养方式对蛋鸭生产性能的影响

试验按饲养方式不同设3个处理组:传统的水面圈养(对照组)、无水面旱地圈养结合间歇喷淋(试验1组)、笼养(试验2组),以测定各组产蛋期生产性能。结果表明:试验2组500日龄入舍母鸭平均产蛋数为283.3枚、总蛋重为18．86 kg,极显著(P<0．01)低于对照组(312,1枚、20．67 kg)和试验1组(306．90枚、20．31 kg);对照组产蛋期死亡淘汰率为7．4％,极显著(P<0．01)高于试验2组(4．76％)和试验1组(4．23％);试验1组全期饲料转化率为2．72,极显著(P<0．01)低于对照组(2．90)和试验2组(3．05)。说明旱地平养结合间歇喷淋的饲养方式,不仅不影响蛋鸭的产蛋性能,而且显著降低饲料消耗,可以替代传统的水面饲养方式。

Effects of Breeding Modes on Performance of Layer Duck

A total of 1260 one-day old Shanma Ducks were randomly divided into three groups to determine the laying performance. The control group was reared in traditional mode with pool. Experimental group one was reared in intensive mode without pool but with intermittent spray. Experimental group two was reared in cases. The results showed that total egg number at the 500 day-old in experimental group two was 283.3, total egg weight was 18.86 kg, which was significantly lower than those in control group(P< 0.01). The total egg number at 500 day-old in experimental group one was 306.9, total egg weight was 20.31 kg, which was no significant difference with control group(P> 0.05). The culling rate of group one was 4.76%, while group two was 4.23% and both were significantly lower than that of control group (P < 0.01). The feed conversion ratio of experimental group one was 2.72, significantly lower than that of control group (P < 0.01), experimental group two was 3.05, significantly higher than that of control group (P < 0.01). Thus layer ducks can be reared in intensive house without pool but with intermittent spray on the yard instead of on the pool.
