摘要
传统观点认为种鸽的配种期为4～10月龄，性别比例为1：2.5～4。本试验研究了不同性别比例对受精率的影响和开产后受精率及蛋重的变化规律。结果表明，开产二周后，各组受精率差异不显著。此时受精率、蛋重、蛋形基本稳定，产蛋也进入高峰期。结果提示种鸡的配种时间可提前至2．5月龄，性别比例提高为1：4～5．5，在不影响种鹑和后代质量的前提下，可大幅度提高种鹑场的经济效益。
The results showed that there was no significant difference between three groups (P> 0. 05 ) at two weeds after sexmaturity. Furthermore, the egg shape, the fertility rate, and the egg size had been all stabl, and the egg- laying had entered flushseason. The results suggested that he seed preduction period should be fixed on 2. 5 months instead of 4 months of age, and the sexratio be 1: 4～5. 5. It would bring about great economic efficiency to the breeding farm.
