Abstract

1. To determine the average rate of increase in size of pullet eggs, the first 24 eggs laid by each of 56 pullets were weighed accurately. Data as follows:

1st—4 eggs; averaged 47.6 gms.
2nd—4 eggs; averaged 49.4 gms.
3rd—4 eggs; averaged 50.0 gms.
4th—4 eggs; averaged 50.6 gms.
5th—4 eggs; averaged 51.5 gms.
6th—4 eggs; averaged 52.6 gms.

(Weight of a No. 1 market egg should be 56 grammes). Considerable variation of the weight of eggs laid by individuals was noted. The average however, indicates a consistent increase.

2. Loss in weight of eggs during natural incubation. There is much variance of opinion as to the rate of evaporation of moisture during natural incubation. In an effort to determine whether evaporation was greatest during the first or the last part of the hatch, forty eggs were weighed at regular intervals during the time….

1. 为了确定小母鸡鸡蛋大小的平均增长速度，对56只小母鸡每只产下的前24个鸡蛋进行了准确称重。数据如下:1 - 4只鸡蛋;平均47.6克。2 nd-4鸡蛋;平均49.4克。3 rd-4鸡蛋;平均50.0克。4 th-4鸡蛋;平均50.6克。5 th-4鸡蛋;平均51.5克。6 th-4鸡蛋;平均52.6克。(市场上卖得最好的鸡蛋重量应该是56克)。人们注意到个体所产蛋的重量有很大的变化。然而，平均值表明持续增长。卵在自然孵化过程中重量减少。关于自然孵化过程中水分蒸发的速度，有许多不同的意见。为了确定蒸发量是在孵化的第一个阶段还是最后一个阶段最大，在....期间，每隔一段时间就对40个鸡蛋进行称重
