摘要
将48周龄黄金褐蛋鸡10只随机分成两组,对照组喂基础日粮,试验组用2.5%的柑桔皮粉等量替代玉米,结果表明:试验组氮表现代谢率为49.24%,比对照组(44.35%)提高了4.89个百分点,差异显著(P<0.05)。
10 Golden-brown laying hens were randomly divided into two groups.The Control group was fed with basal ration and the treatment group was fed on ration with 2.5% citus peel meal instead of 2.5% corn.The results showed that the apparent rate of nitrogen metabolism was 49.24% which was 4.89 percent point higher than that of the control group (P<0.05)
