The effects of high temperature-low relative humidity,low temperature-high relative humidity and constant temperature-constant relative humidity on embryonic mortality,hatchability of fertile eggs,rate of healthy chick,weightloss rate of embryonic eggs with different ages and chick weight at birth were measured.
使用我国山鸡种蛋进行了3个人工孵化试验,每个试验设2次重复,测定在不同的孵化温度与相对湿度条件下,即高温度—低湿度、低温度—高湿度与恒温—恒湿,对胚胎发育的死亡率、受精蛋孵化率、健雏率、不同胎龄胚蛋的失重率及雏山鸡出生重的影响。
