I saw this at Equine Affaire last year but I'm not sure what kind of seed was used. I saw one of the breed demo horses get his first taste and he went nuts over it. At the time I thought any horse in Southern California would go nuts over a patch of such lush grass - what's the big deal? So, I don't have a company name or much info to give you. Now, I'm interested too! I was thinking about sprouting some seed in an effort to tempt my horse to eat more. Horse Expo comes to town next month so I'm going to try and track down a similar company.
