Semen was frozen (in glycerol) from 24 males (9 months of age) of a commercial broiler line and was inseminated intravaginally into old (19 months of age) and young (7 months of age) commercial Leghorn females. Duration of fertility, percent fertility during duration and percent hens fertile were measured. The means for old and young hens respectively, were: duration of fertility (1.4 +/- 0.4 and 1.6 +/- 0.5 days), percent fertility (19.1 +/- 5.1 and 15.9 +/- 5.1) and percent hens fertile (29.2 +/- 7.7 and 25.3 +/- 7.2). The "t" test revealed no significant (P greater than 0.05) differences between old and young females in fertility.
采集了某商业肉鸡品系24只9月龄雄性的精液（添加甘油冷冻保存），并经阴道输精给19月龄老龄和7月龄幼龄的商业来航蛋鸡。测定了受精持续时间、受精期间的受精率以及产蛋母鸡的受精率。老龄和幼龄母鸡的各项均值分别为：受精持续时间（1.4±0.4天和1.6±0.5天）、受精率（19.1±5.1和15.9±5.1）以及产蛋母鸡受精率（29.2±7.7和25.3±7.2）。“t”检验显示老龄和幼龄母鸡在受精方面无显著差异（P＞0.05）。
