【摘要】 本试验在相同饲养条件下,对番鸭育成期(10～26周龄)在日粮不同粗蛋白水平(11.5%、13%、14.5%)和不同饲养方式(混养、分饲)下进行比较分析。结果表明:在12～14周龄后,日粮不同粗蛋白水平对三组番鸭的生长发育影响都较小,且公母分饲组比混养组饲养效益高。番鸭育成期采用限制饲养和适当降低日粮粗蛋白水平,可提高饲养效益。更多还原

【Abstract】 In the same feeding conditions,the test analysed in the diets of different crude protein levels (11.5%,13%,14.5%) and different feeding methods(polyculture,sub-feeding) on 10～26-week-old muscovy duck rearing period.The results showed that:In the 12～14 weeks of age,the diets of different crude protein levels have little effect on growth and development of muscovy duck.In order to improve breeding efficiency, we shall restrict feed and reduce the crude protein level.Male and female sub-feed is more efficient than the polyculture rearing.更多还原
