I have a gelding that is probably 24-27 years old (we don't know exact age, that's just going off of what the vet is saying) and he is becoming harder and harder to keep weight on him. He is on 8 acres of pasture with my mare and has hay everyday. He's very healthy, just had his teeth floated in May and shots and everything. I also give him a scoop of senior feed from our local farm bureau. What feed and or suppliments would you recommend giving my old guy to keep weight on him this fall and winter?
Also I have a mare who is 6, full of energy and is to easy of a keeper. She is always fat except for in the winter (according to her old owners as I've only had her since the beginning of spring). What would you recommend for a young energetic horse as well?
