Showcasing equine reproduction research

In July 2023, equine reproductive researchers from around the world came together for the 13th International Symposium of Equine Reproduction in Foz do Iguaçu, Brazil. Congratulations must be given to the local organising committee in Brazil, who not only organised a successful symposium but who memorably welcomed everyone with their unique hospitality and enthusiasm. There were 244 presentations and posters, with material on stallions, assisted reproductive technologies, the non-pregnant mare, the pregnant mare and parturition and perinatology. There was an enormous amount of new and cuttingedge material presented and I am still trying to process a proportion of this weeks later. Donkey reproduction was well represented with research on donkey semen, haemorrhagic anovulatory follicles, ovulation induction, use of cloprostenol and the use of power-Doppler ultrasonography in jennies. There was material presented on non-antibiotic ‘alternative’ therapies for endometritis, from bacteriophages to ozonated sunflower oil and a number of papers on potential therapies for modulating the inflammatory cascade in response to breeding.
