【摘要】 选择 15只年龄为 9日龄的幼龄白鹭进行试验 ,随机分为A ,B ,C 3组 ,A组为对照组 ,喂以鱼鳅 ,B ,C两组为试验组 ,B组喂鱼鳅及配合饲料 ,C组在B组的基础上用 4g配合料代替 4g鱼鳅 ,饲喂量每周增加一次 ,试验期为 90天。结果表明 ,试验B组与对照A组和试验C组相比 ,在增重方面 ,差异显著 (P <0 .0 5 ) ,而在体长、咀裂长 ,翼展度等生长发育指标上差异均不显著 (P >0 .0 5 )。因此 ,以营养需要方面考虑 ,在 49日龄以前完全可用 30 %的人工配合饲料 ,在 49日龄以后 ,可以用 5 0 %的人工饲料来代替白鹭天然的动物性饲料。更多还原

【Abstract】 Fifteen 9-day-old young egretlaes were used in a 90-day artificial rearing experiment and divided into three groups. Group A was used as the control and fed with loach; group B was fed with loach and formula feed; and group C was fed with a diet similar to that for group B with 4g more formula feed substituting for loach. Group B was significantly different from group A or group C ( P <0.05) in weight gain, while no significant differences were observed in wing span and other growth indicators. It is therefore concluded that artificial feed up to 30% may be used to feed egrets no older than 49 days and a rate of 50% of artificial feed may be used thereafter.更多还原
