The team over at the Equine Veterinary Journal do a great job supplying a go-to journal for equine veterinarians (and professional horse people who like to read and listen in) across the world - they publish high quality, peer reviewed, clinical and applied research information.
As we know, as a rider/trainer we're all a little bit vet/psychologist/magician and more information is always better than less. If your mind runs to learning on a scientific basis, the EVJ is a great spot to look into. In particular, their podcasts can regularly be a great listen.
