摘要
50日龄雌性鹌鹑 1 500只，随机等分成 5组，给予不通风、 0.2 m/s， 0.4 m/s， 0.6 m/s， 0.8 m/s送风 5种处理，观察不同环境温度下的产蛋率和蛋重。结果表明， 21℃～ 27℃时鹌鹑产蛋率受风速影响不大， 30℃以上时， 0.4 m/s以上风速时的鹌鹑产蛋率明显高于无风时， 20℃以下时，鹌鹑的产蛋率随风速增大而降低。无风时蛋重随温度的变化情况与产蛋率的变化相似，不同温度下送风均有增加蛋重的效应，而以 0.4 m/s为宜。
： We divided 1 500 50－ day Quails into 5 groups in random and provided them with 5 kinds of wind speeds:0 m/s,0.2 m/s,0.4 m/s,0.6 m/s,0.8 m/s.By studying their laying rate and eggs weight in different temperature,we found that when the temperature is 21℃ ～ 27℃ ,the laying rate is slightly influenced by wind speed,while the temperature is over 30℃ ,and the wind speed is over 0.4 m/s,the laying rate is apparently higher than that of no wind.when the temperature is less than 20℃ ,the stronger the wind is,the less the laying rate is,Without the wind,the change of egg weight is similar to the laying rate.The eggs weigh more in every different temperature,especially when the wind speed is 0.4 m/s.
