Heifers were each given 2ml of 1% solution of chlormadinone (CAP, Bovisynchron) for 15 days. Those in group I received one daily dose, while group II received half the dose twice a day. Oestrus was synchronized in all but two heifers. In group II there was a concentrated occurrence of oestrus, so that all heifers could be inseminated on the 5th and 6th days, and earlier inseminations were not needed. This decreased the time required and the number of semen pellets. Results of insemination in two of the three subgroups of group II were 51% in one and 61% in the other, compared with between 32 and 39% in the other subgroup and in group I. Ways of improving the results are discussed.
给小母牛每头每天注射2毫升1%的氯地孕酮溶液（CAP，牛同期发情素），持续15天。第一组小母牛每天注射一次，而第二组小母牛每天分两次注射半量。除两头小母牛外，所有小母牛的发情周期都实现了同步。在第二组中，发情集中出现，因此所有小母牛都可以在第5天和第6天进行授精，无需提前授精。这减少了所需时间和精液颗粒数量。第二组三个亚组中的两个亚组的授精结果，一个亚组为51%，另一个亚组为61%，而其他亚组和第一组的授精结果在32%至39%之间。文中讨论了提高结果的方法。
