摘要虽然人们怀疑鸡的品种和品系之间以及火鸡家族之间的生育能力存在差异，但很难确定这种差异的意义。在自然交配条件下，社会、机械和其他环境因素可能会掩盖雄性精液的受精能力和/或雌性输卵管的生理接受性。人工授精技术提供了一种克服其中一些困难的方法。最近，通过使用近交系的鸡，有证据表明繁殖力受到遗传因素的影响。Bernier等人。(1951)报告了与自交系和近交系及杂交种自然交配后的生育力，每两年有三个时期。这些工作人员发现，在观察到的生育率差异中，女性的起源即使不是最大的部分，也是很大的一部分。…既不会削弱生育能力，也不会提高生育能力
Abstract WHILE differences in fertility between breeds and strains of chickens and between families of turkeys have been suspected, it has been difficult to establish the significance of such differences. Under conditions of natural mating, social, mechanical and other environmental factors may mask the fertilizing ability of a male’s semen and/or the physiological receptivity of the oviduct of the female. The technique of artificial insemination provides a means of overcoming some of these difficulties. Recently through the use of inbred lines of chickens evidence has been obtained that fertility is influenced by genetic factors. Bernier et al. (1951) have reported on fertility following natural mating with inbred and outbred lines and crosses for three periods in each of two years. These workers found that the origins of females accounted for a great part, if not the greatest part, of the differences in fertility observed. Fertility was neither impaired nor enhanced by …
