Resumen: Eighty two Majorera goats were used in a farm on the island of Gran Canaria (28° North latitude and 15°35′ West longitude), Spain. The objective of the study was to determine the pregnancy rate of three cycle control treatments in autumn. In the first treatment, an intravaginal sponge impregnated with Flugestone acetate (Chronogest 20 mg) was left for 11 days, and a dose of Equine Serum Gonadotropin (250 UI) (Foligon 5000 UI) as well as a dose of D‐cloprostenol (1 ml) (Luteosyl 0.075 mg/ml) was applied intramuscularly at the time of extraction (n = 27). The second treatment consisted of the application of two doses of D‐cloprostenol (1 ml) (Luteosyl 0.075 mg/ml) at an 11 day interval (n = 35). The third treatment was the same as the second with an administration of Gonadorelin intramuscularly (2 ml) (Gonasyl 50 μg/ml) at the time of insemination (n = 20). 48 h after the end of the treatment without heat detection, the goats were inseminated with fresh semen diluted with skimmed milk obtained from males from the same farm. A minimum dose of 400 × 106 sperm was used. Pregnancy diagnosis was made 35 days after insemination by ultrasound examination. The pregnancy rate was 40.74% in the first group (11/27), 31.43% in the second (11/35) and 15% in the third one (3/20). Significant differences were observed (p < 0.025) among treatments. Comparing the first and the second treatment, significant differences were also observed (p < 0.001). Therefore, the preferred cycle control treatment using artificial insemination in goats of a commercial herd (in the Canary Islands) in autumn is the first one
