| 摘 要： | 对AA肉用种鸡受精率及其主要影响因素——种用时期,公母比例,体重、体质和腿脚状况,以及舍温等进行了一系列的分析研究。提出改进肉用种鸡受精率的综合技术措施。在一般生产条件下,肉用种鸡全期平均受精率可达90％以上;在优良生产条件下,肉用种鸡全期平均受精率可达94％以上。

| Abstract: | A series of studies for improving the fertility of broiler breeders was conducted. The data on fertility came from 30 flocks, and approximately 90 000 sets of AA broiler breeders were statistically analysed and simulated by a computer. The emphasis of research was to expound some main factors that affect fertility -breeding period,sex ratio, body weight & constitution , leg & shank conditions, and house temperature. Integrated technical measures to raise the fertility of broiler breeders were worked out and recommended. Average fertilities of 90% under general production conditions and of 94% under ideal production conditions could be expected. |
