So there have been a couple occasions when I take Koby into the indoor arena and he starts licking the dirt. I don't know what it could be other than a vitamin deficiency. Does anyone's horse do this? Or is Koby a complete weirdo? ;) I also want to switch his grain. Right now he is on a complete feed which is just an alfalfa based grain. I don't think it has very many vitamins. It's super cheap and it was what my old trainer was giving him but now I want to get in to gaming,and I think he needs a little something more...he is an 8 year old and gets turned out every day. He gets about 2 pounds of the complete feed in the morning and grass hay throughout the day. Does anyone know of any highly nutritious grains they think would be good? What do you feed your horse?
