Abstract
The experiment was conducted with thirteen breeds as follows: S. Campine, S. S. Hamburg, D. Cornish, S. P. Wyandotte, G. Wyandotte, C. Wyandotte, Bu. P. Rock, Pt. P. Rock, Bu. Orpington, W. P. Rock, W-F Bk. Spanish, M. Houdans, and S. C. Wt. Leghorn.
The composit collection of eggs were saved for five days and placed in an incubator. Eighty-three per cent were fertile and of the fertile eggs 80 per cent hatched. The cocks were then removed. The test of all eggs laid by all flocks after removal of the male birds was as follows:—First day, 85 per cent fertility; second day, 91 per cent; third day, 82 per cent; fourth day, 71 per cent; fifth day, 62.5 per cent; sixth day, 50 per cent; seventh day, 63 per cent; eighth day, 53 per cent; ninth day, 29.4 per cent; tenth day, 33 per cent; eleventh day, 37.5 …
试验选用了13个品种:S. Campine, S. S. Hamburg, D. Cornish, S. P. Wyandotte, G. Wyandotte, C. Wyandotte, Bu。P. Rock, Pt. P. Rock，但是。奥平顿，W. P.洛克，W. f . Bk.西班，M. Houdans和S. C. Wt. Leghorn。鸡蛋的混合物被保存了5天，并放在孵化器中。83%的卵是可育的，80%的卵孵化了。然后把公鸡移走。除去雄鸟后，对所有鸡群所产蛋的测试如下:-第一天，85%的受精率;第二天，91%;第三天，82%;第四天，71%;第五天，62.5%;第六天，50%;第七天，63%;第八天，53%;第九天，29.4%;第10天，33%;第十一天，37.5…
