摘    要:选用18周龄健康、体重基本一致的海兰褐佳蛋公鸡和北京Z系公鸭各48只,以Sibbald“真代谢能(TME)”法测定了公鸡和公鸭常用谷物、饼粕和油脂等3大类9种常用饲料的代谢能。结果表明:鸡和鸭对饲料能量利用存在明显的差异。AME除棉粕和玉米淀粉鸭与鸡差异不显著外(P>0.05),其余7种饲料AME鸭都比鸡高;TME玉米淀粉鸭与鸡差异不显著(P>0.05),其余8种饲料TME鸭都比鸡高。48h鸭内源能排泄量(113.10MJ)比鸡(88.88MJ)高(P<0.01)。并且饲料蛋白质含量越高,鸭和鸡饲料AME、TME值之间差异越大。

关 键 词:畜牧学  代谢能  公鸡  公鸭

Abstract:In this experiment,48 Hy-Line Brown cockerels and 48 Peking drakes with the same weight and old(18 weeks)were employed to bioassay AME,TME and endogenous energy of 9 plant feedstuffs,including paddy,corn grain,wheat grain,wheat bran,soybean oil,beef tallow,soybean meal,cottonseed meal,peanut meal and corn starch.And every 8 cockerels and drakes were used to determinate one feedstuff.The results showed that there were significant differences of utilizing energy between cockerels and drakes(P < 0.05,or P <0.01).Except ATM of cottonseed meal and corn starch and TME of cottonseed meal,AME and TME of the rest feedstuffs for drake were significantly higher than those for cockerels.During the period of 48-hour fecal collection,the amount of endogenous energy in drakes was significantly higher than that of chicks,the effects varied with the method of collecting fecal.And the content of protein in feedstuff is higher,the disparity is wider between cockerel and drake.
Keywords:animal science   metabolisable energy   cockerel   drake
