ABSTRACT

In order to evaluate the rate of follicular growth, the response time to ovulation and the percentage of ovulation in Quarter Mile postpartum mares, two treatments (T) were applied, the first with deslorelin acetate (DA) and the second with human chorionic gonadotropin (hCG). The study was conducted during January to June 2018, with sixteen 7-year-old mares, 450 kg of weight and 4.5 deliveries on average. Ovarian follicular diameter was evaluated by real-time transrectal ultrasonography in response to experimental treatments, in mares with ovarian follicles ≥ 35 mm in diameter: T1 (n= 8): Application of 1 mg of DA intramuscularly (IM), and T2 (n= 8): Application of 2500 IU of hCG via IM. There were no differences (P› 0.05) in the rate of follicular growth (AD: 0.48 ± 0.006 mm and hCG: 0.45 ± 0.035 mm), the time of response to ovulation (AD: 46.75 ± 0.48 h and hCG: 56.00 ± 8.00 h) and the percentage of ovulation (AD: 8/8, 100% and hCG: 7/8, 87.5%) in the postpartum mares evaluated. It is concluded that deslorelin acetate and human chorionic gonadotropin respond to ovarian activity in Quarter Mile postpartum mares with ovarian follicles ≥ 35 mm in diameter.
