LARA-CASTILLO, Jorge et al. Reproductive response in creole mares treated with deslorelin acetate. Abanico vet [online]. 2021, vol.11, e407. Epub 04-Abr-2022. ISSN 2448-6132. https://doi.org/10.21929/abavet2021.43.
The deslorelin acetate effect on reproductive response was evaluated in creole mares in Michoacán State. Ten mares were treated intramuscularly and distributed in a Control group (CG; n = 5) 1 ml of distilled water as a placebo and the experimental group (DG; n = 5) 1.5 mg of deslorelin acetate. When the follicle reached 35 mm in diameter, the mares were treated according to the assigned group. The ovarian activity was monitored every 24 h. The incidence (%) of anovulatory hemorrhagic follicles (AHFs), ovulation rate (%), follicular growth per day (mm), follicular diameter at ovulation (mm), and time to ovulation (h) were determined. The incidence of AHFs was higher (X2 = 3.83) in the CG than in DG (25.58% vs. 5.8%, respectively). The ovulation rate was higher (X2 = 4.76) in DG than in CG (94.11% vs. 74.41%, respectively). The hormone administration did not affect (p> 0.05) the follicular growth per day or the follicular diameter, still, ovulation occurred (p <0.01) at 39.45 ± 2.95 h and 89.47 ± 3.62 h in the DG and CG, respectively. deslorelin acetate reduced the incidence of HAFs and increased the ovulation rate.
