Abstract :The aim of this study was to investigate the efficacy of the use of two different progestagens either singly or in a combination with GnRH on queen contraception. The study was performed on a total of 73 female cats of various breeds at various stages of cycles. Queens at interoestrous insert ignore into journalissuearticles values(n=35); and oestrous periods insert ignore into journalissuearticles values(n=38); of sexual activity were treated under two main groups. Twenty cats of the first main group at interoestrous period insert ignore into journalissuearticles values(Group-1/A); were administered 30 mg/kg insert ignore into journalissuearticles values(sc); proligestone insert ignore into journalissuearticles values(PRG); and the remaining 15 cats insert ignore into journalissuearticles values(Group-1/B); were administered 25 mg insert ignore into journalissuearticles values(sc); megestrol acetate insert ignore into journalissuearticles values(MA);. The cats at oestrous period were first given 50 mg gonadotropin releasing hormone insert ignore into journalissuearticles values(GnRH); insert ignore into journalissuearticles values(im);. 48-96 hours following the application 23 of these cats insert ignore into journalissuearticles values(Group-2/A); were administered 30 mg/kg insert ignore into journalissuearticles values(sc); PRG, while the other 15 cats insert ignore into journalissuearticles values(Group-2/B); were administered 25 mg insert ignore into journalissuearticles values(sc); MA. The disappearance of oestrous symptoms was established to be 2.85±0.74 days in Group-1/A, 2.93±1.35 days in Group1/B, 3.08±0.84 days in Group-2/A and 2.86±0.64 days in Group-2/B. Following hormonal injection the periods of remaining calm were established to be 8.00±2.20 months in Group-1/A, 3.33±1.01 months in Group-1/B, 7.57±2.35 months in Group-2/A and 4.90±2.65 months in Group-2/B. No difference has been established among mean values from the point of view of the disappearance of oestrous symptoms among groups insert ignore into journalissuearticles values(Group-1/A:Group-1/B= p
