STIMULATION OF THE REPRODUCTIVE FUNCTION IN COWS WITH PRID'S

The aim of the paper was to synchronize the estrus and ovulations in cycling cows and to simulate the ovarian function in non-cycling cows. PRID are frequently used in reproductive control programs at dairy cows. The aim of our paper was to synchronize the estrus and ovulations in cycling cows and to simulate the ovarian function in non-cycling cows. At 28 cows with cycling ovarian activity the duration of treatment was 7 days. After the device removal 2 ml Proliz (0.450 mg Cloprostenol) were administered. AI was performed at 72 hours after the end of the hormonal treatment and 20 (71,42 %) were diagnosed as pregnant. At the 34 anestrous cows the duration of the treatment was 10 days. With 24 hours before the redrawn of the PRID, 500 IU eCG were administered. AI was performed at 60 hours from the end of the hormonal treatment and 14 (41.17%) cows were diagnosed as pregnant. The PRID spirals can be used with success in synchronizing the ovulations in cycling cows and in anestrous therapy in non-cycling cows.
