To determine the duration of the antifertility effect of glycerol in the chicken's vagina, groups of 15 Leghorn-type hens were each given 0.1 ml. of a 2.076 M glycerol solution at time intervals from 0 to 10 minutes before and after insemination with 0.1 ml. of pooled semen. Eggs were set weekly and candled at 7 days of incubation to determine fertility. Fertility of eggs collected during days 5--7 was significantly (P less than .01) reduced by the glycerol solution when it was administered between 5 minutes before and 10 minutes after insemination. The antifertility effect disappeared within 10 minutes after glycerol deposition.
为确定甘油在鸡阴道内抗生育作用的持续时间，将15只来亨鸡型母鸡分为几组，在输精0.1 ml混合精液之前和之后的0至10分钟的时间间隔内，每组给予0.1 ml 2.076 M甘油溶液。每周收集种蛋并在孵化7天时照蛋以确定受精情况。当在输精前5分钟至输精后10分钟之间给予甘油溶液时，第5 - 7天收集的种蛋受精率显著降低（P小于0.01）。甘油注入后10分钟内抗生育作用消失。
