| 摘 要： | 对320只肉用雏鸡在不同温度和不同营养水平下的随意采食量、随意饮水量的观察表明：能量水平高低（基他营养水平基本衡定）直接影响雏鸡的随意采食量。布蛋白质水平的高低对随意采食量没有明显的影响，但蛋白质或能量水平的高低均显著影响雏鸡随意饮水量（P＜0．01）。同时采食量与饮水量存在正相关，这种相关不受营养水平高低的影响，还讨论了随意食量、随意饮水量随日龄和环境温度变化的规律以及与雏鸡体重的回归方程。

| Abstract: | Through the observation of voluntary intake and voluntary drinking under diffe-rent levels of nutrition and environmental temperature on chick(320), results showed:there was high effect on Chick related to different 1evels of metabolizable energy offood. There was no significant effect on voluntary intake on chick related to differentlevels of crude protein of food. But, there were high effects on the voluntary drin-king on chick related to metabolizable energy and crude protein of food. In this article,the law of variation of voluntary intake and voluntary drinking due to the variationof age of chick, weight and environmental temperature was discussed. |

| Keywords: | voluntary intake voluntary drinking the level of nutrition environmental temperature chick |
