All bitches were physically examined to determine that they were in anoestrus at the beginning of the study. Then following methods were carried out: Pregnant Mare Serum Gonadotrophin (PMSG) and Human Chorionic Gonadotrophin (HCG) Application (lst.Method); Diethylstilbestrol (DES), HCG and PMSG Application (2nd.Method); Pulsatile Gonadatrophine Releasing Hormone (GnRH) Aplication (3rd.Method); Cabergoline Applications (4th.Method); Control Group (5thMethod:). Vaginal cytological;examinations of all bitches were made every other day and bitches which showed oestrus were mated with the sires. As a result 100 % oestrus and 40 %pregnancy in the 1st method; 70% oestrus and 30 % pregnancy in the 2nd method; 10 % oestrus and no pregnancy in the 3th method were found. In the 4th method 90 %oestrus and 80 %pregnancy were found the results were evaluated statistically and were compared with the results at the literatures.
