| 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，C3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与与对照A组和试验C组相比，在增重方面，差异显著（P＜0．05），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＞0．05）。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50％的人工饲料来代替白鹭天然的动物性饲料。

| 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. |
