| 摘 要： | 采用人工气候试验证实,星杂288,70—140日龄育成小母鸡对环境温度的适应范围较宽。平均温度8.6—20.2℃均适合小母鸡的生长发育。冷凉温度(8.6℃)下自由采食时,小母鸡每只每天的能量食入量比中等温度(20.2℃)下多1.6—54.6卡,日粮食入量多0.7—18.2克,日增重多1.73—2.01克;但能量损失较大,每克增重多消耗277卡。育成小母鸡最适宜的生长温度为15—20℃。

THE EFFECT OF ENVIRONMENTAL TEMPERATURE ON THE NUTRITIONAL PHYSIOLOGY OF GROWING PULLETS |
| |
| Abstract: | The experiment conducted in the artificially temperature-controlled chambers showed that the growing pullets grew and developed well at age of 70-140 days in the tested environment. Compared with the pullets in the moderate temperature (20.2℃), the pullets in the cold environment(8.6℃) had higher feed intake and higher energy intake and higher weight gain, but required more energy (227 kcal)per gram gain. The optimum temperature for the growing pullets was in the range of 15 to 20℃. |
