The evolution of fertility programs for lactating dairy cows
Dairy farmers, dairy veterinarians, and dairy consultants are continually challenged to stay current on the latest recommendations for synchronization protocols. An excellent and up-to-date source of information on synchronization protocols can be found at the DCRC web site: http://www. dcrcouncil.org/. Protocols recommended by the DCRC are reviewed and updated by researchers who develop and test these protocols, and are based on the latest peer-reviewed research published in the scientific literature. The purpose of this paper is to overview the key research underlying development of fertility programs for lactating dairy cows.
