This study was aimed to develop a novel reproductive management program based on postpartum reproductive monitoring using milk progesterone analysis. A series of experiments on the reproductive monitoring were carried out on several commercial dairy herds in Japan and Germany. The results showed that the monitoring-based reproductive management was useful to improve reproductive efficiency. Use of embryo transfer,, in particular, for the first postpartum breeding in lactating cows with normal recovery of reproductive activities was likely to improve fertility. For the further improvement nutritional monitoring in addition to reproductive monitoring is suggested to be promising.

本研究的目的是开发一种新的生殖管理方案的基础上，产后生殖监测，使用牛奶孕酮分析。在日本和德国的几个商业奶牛群上进行了一系列的繁殖监测试验。结果表明，以监测为基础的繁殖管理有利于提高繁殖效率。特别是在泌乳奶牛产后第一次配种时使用胚胎移植，生殖活动正常恢复，可能会提高生育力。为了进一步改进，除了生殖监测外，营养监测是有希望的。
