半番鸭网上平养不同饲养密度试验

Net bed farming mule duck rearing density test

在网上平养条件下对育雏期和生长肥育期不同阶段的大型白羽半番鸭设定不同饲养密度,进行生产性能指标的对比试验,得出初步试验结果:育雏期(0～14日龄)饲养密度27羽/m2左右较为适宜,生长肥育期15～28日龄8～9羽/m2,29～42日龄5～6羽/m2,43～56日龄4～5羽/m2较为适宜。

The production performance of large white feather mule ducks of the brooding period and growth period which were feeding in different rearing density on the net bed were tested and compared. The results showed： in the brooding period（0 to14 day-old）, the appropriate feeding rearing density was about 27 ducks/m2; in the growth period, the appropriate feeding rearing density of the 15 to 28 day-old was 8-9 ducks/m2, 29 to 42 day-old was 5-6 ducks/m2, 43 to 56 day-old was 4-5 ducks/mE.
