Considering adding oil
I'm thinking about adding Canola oil to my horse's diet. 7 year old Paint horse (Almost 1200lbs but I'd like to see him get up to that.), some where between hard and easy keeper, leaning more towards hard. He gets 1.5lbs of E32 per day, free choice hay, and unless it's raining, he goes out into the pasture 10 hours per day. I ride him almost every day for about 1-1.5hrs.
I've heard that adding an oil will help him keep on weight and make his coat shiny :)
I'm considering canola oil, opinions? How much should I start out with?
