    摘要:

    测定500只罗曼蛋鸡(23-31周龄)分别在冷季(1997-01-01-1997-03-03,鸡舍温度-4.5-10.2℃,平均4.3℃)和温季(1997-04-01-1997-06-01,鸡舍温度12.8-27.1℃,平均20.7℃)对饲粮养分转化为蛋相应成分的效率,结果表明,鸡在温季对饲粮绝大多数种类养分的转化率都显著(P<0.001或P<0.01或P<0.05)地高于鸡在冷季对饲粮养分的转化率。

    Abstract:

    The efficiencies of diet nutrients converted into corresponding components of eggs by 500 Loman laying hens were measured,respectively.The result showed that the conversion efficiencies during warm season were significantly higher than those during cold season.
