We were extremely fortunate in that our lead lecturer Jos Mottershead was invited to attend the 13th International Symposium on Equine Reproduction (ISER XIII) in Brazil as a delegate. This has afforded us the opportunity to present new information to the breeding public – be they veterinarians in the field, lay breeders, or the many others for whom the information would be useful – via the website, our short courses and individual tuition, as well as the EquineRepro Facebook Group that we operate. In this latter media, we are presenting weekly posts with information which has immediate clinical value, and we are re-presenting those posts here on the website for our viewers as and when they are published in the Facebook Group.
