Özet

Dairy cows that are being cared for in family businesses were used to compare the pregnancy rates by applying different time periods, using progesterone devices, and using fixed-time artificial inseminations. The cows were randomly divided into 3 groups. Group 1(n = 56); On day 0, GnRH (IM) (10mg Buserelin acetate, Ovarelin, CEVA DIF) + Progesterone implants (PRID (R)) (1,55 g progesterone CEVA), Day 8 PGF2 alpha (Dinoprost tromethamine, 25 mg, Dinolytic, Pfizer), Day 9 Progesterone implants removal + PGF2 alpha, insemination was performed at 56th hours insemination after the second PGF2 alpha injection. Group 2 (n = 50); on day 0, GnRH (IM) + Progesterone implants, PGF2 alpha (IM) on the 8th day, Progesterone implants removal + PGF2 alpha on the 9th day, insemination was performed at 48th and 72th hour after the second PGF2 alpha injection. Group 3 (n = 53); on day 0 GnRH (IM) + Progesterone implants, on the 5th day PGF2 alpha injection, day 6 PGF2 alpha (IM) and remove progesterone implant and insemination at 56 hours after the second PGF2 alpha. The average milk yield was recorded Group 1 16.66 +/- 5.28 kg, Group 2 13.46 +/- 3.05 kg. and Group 3 was recorded as 15.35 +/- 4.60 kg. Pregnancy diagnoses were performed 35 days after the artificial insemination. The pregnancy rate was 41.07% in Group 1, 42% in Group 2, and 52.83% in Group 3. As a result; pregnancy rates were similar in all three groups. It has been concluded that synchronization with progesterone can solve many reproductive problems.
