An experiment was conducted with 546 Japanese breeder quail to determine the effect of age and egg weight on day-old chick weight over a 16-wk reproduction period. Weight of chicks hatched from the same or different size eggs was found to be affected by parental age. The largest increase in chick weight occurred after 10 wk of age. It was found that egg weight did not affect the hatching weight if egg weight was above 11 g.
用546只日本种鹌鹑进行了一项实验，以确定在16周的繁殖期内年龄和蛋重对一日龄雏鸡体重的影响。结果发现，同一大小或不同大小鸡蛋孵化出的雏鸡体重受亲本年龄的影响。雏鸡体重最大增幅出现在10周龄之后。研究发现，如果蛋重超过11克，蛋重不会影响孵化体重。
