Article Synopsis
- - The study examines the impact of platelet-rich plasma (PRP) on uterine inflammation and pregnancy rates in jennies (female donkeys) inseminated with frozen donkey semen, which generally shows lower success in jennies compared to mares.
- - Three groups of jennies were tested: a control group with no treatment, a group receiving a single PRP infusion, and a group getting double PRP infusions around ovulation and artificial insemination (AI).
- - Results indicated that while S-PRP reduced intrauterine fluid (IUF) accumulation shortly after AI, no significant differences were observed in pregnancy rates among groups, suggesting PRP treatments did not effectively improve outcomes for jennies
Reproductive biotechniques in the equine species have advanced in the last decade and horse breeders have started to question the possibilities of interfering in the determination of foal sex. The aim of the present study was to verify whether the variables mares and stallion's age, side of the ovary containing the preovulatory follicle, preovulatory follicle diameter, time between breeding and ovulation, and ovulation inducing hormones influence the sex of the foal. A total of 259 reproductive cycles of 160 mares and 22 Thoroughbred stallions were used.

Embryo mortality (EmbM) was determined every time a mare was found open after a positive pregnancy diagnosis. Parturition to breeding interval, pregnancy rate (PregR) and EmbM rate were the dependent variables and the treatments were breeding on the FH or on SH.
