摘要: 本文探讨日粮中能量、蛋白质和蛋氨酸的含量对圈养蛋鸭性能的影响。能量水平介于2400～2750kCalM·E/kg,能量对产蛋性能影响不大,适宜能量水平以2600kCalM·E/kg为佳。在一定范围内产蛋性能随着蛋白质、蛋氨酸的含量增加而提高,日摄取量分别为29克和493毫克,产蛋性能表现最好。三次重复一致。

Abstract: The effects of dietary energy, protein and methionine level on laying performance of egg-laying duck (Putian Black Duck) wree studied. The energy levels ranged in 2500-2750 kCalM·E/kg, They did not affect significantly on laying performance. The optimum energy level was 2600 kCalM·E/kg. In a certain range, the laying performance increase with the rising of dietary protein and methionine levels. When the daily intake of protein and methionine was 29 g and 493 mg respectively, the laying performance showed the best. Ideal reproducibijity was obtained in the triplicate experiments.
