weight gain, help?
So my horse isn't gaining weight as id like.. and its really odd. He's not skinny, but his ribs are showing slightly so I want him to gain more weight, he came from Nova Scotia to Newfoundland and then to Labrador for the summer, he was on free choice hay in NS as well as 2 litres of Hi-fat hi-fiber and he was a good weight, but he dropped some weight in Newf because he was just on free choice hay.. since he's been here since the beginning of May and he's gained a bit more weight but from what I've been feeding him I would think he should have gained way more..he had free choice hay and 2 litres of Hfhf along with half a water bucket of timothy alfalfa cubes twice a day.. he's now on pasture and 2 litres of co-op brand horse feed (only for the next week, I ran out of hfhf. He's also dewormed reg. Any help guys? Should I consult with the vet?
