Incidence of ovarian follicular cysts and their effect on reproductive performance in dairy cows: A case study in Mexico

The incidence of ovarian follicular cysts (OFC) in relation to reproductive performance in a dairy herd was determined. A total of 1,249 reproductive records of cows during their previous lactation cycle were reviewed. Of all cows submitted to reproductive evaluation due to anestrus or to diagnose p...
