Özet

The aim of the present study was to evaluate the effects of Cosynch protocol on some reproductive parameters in Holstein multiparous cows (MC) (n = 54) and heifers (n = 53). Follicular development, presence of corpus luteum (CL) at different stages of Cosynch protocol, ovulation time and pregnancy rates were evaluated by ultrasonography in MCs and heifers.
