Using Ovsynch protocol versus Cosynch protocol in dairy cows
As a research on the reproductive physiology and endocrinology surrounding the estrous cycle in dairy cattle has been compiled, several estrous synchronization programs have been developed for use with dairy cows. These include several programs that facilitate the mass breeding of all animals at a p...
