My 2 horses escaped their huge pasture and got in to a lot of sugar cane and grass around it. Last time when I gave one of them sugar cane chopped in cubes, he got stomach ache and a light bloat I assume since I saw marks of wallowing on his sides. I never fed it again and now they accidentally ate some. Is there anything I can do to prevent bloat? It's been couple of hours since the incident and hey both look calm and are eating grass in the pasture now, no signs of bloat or distress.
