Reproductive herd health programs have been advocated for many years, and rational approaches that are cost effective have been demonstrated. Dissemination of this information to dairymen can help create a demand for veterinary service. Similarly, the information can be utilized by veterinarians to encourage dairy clients to utilize profitable practices and programs. The study described demonstrated an improvement in biologic goals when a reproductive herd health program was incorporated into the management scheme. The program achieved economic success by reducing costs related to reproduction.
繁殖牛群健康计划已经倡导多年，并且已经证明了具有成本效益的合理方法。将这些信息传播给奶农有助于创造对兽医服务的需求。同样，兽医可以利用这些信息鼓励奶牛场客户采用有利可图的做法和计划。所描述的研究表明，当将繁殖牛群健康计划纳入管理方案时，生物学目标会得到改善。该计划通过降低与繁殖相关的成本取得了经济上的成功。
