Hello everyone! I was given a 15 year old grade mare and her 16 month old colt by some people I know. They were no longer able to care for them and I offered to take them because they had no other place to go and I was planning on getting a horse anyway. The mare (Callie) was a very nice trail horse, solid, dependable, and not at all spooky.
The problem is that she scores about a 1 to a 1.5 on the body score index. She is currently getting the best quality coastal hay I have been able to find. She and her colt are splitting a 75 pound bale throughout the day. I give them the whole bale in the morning and they eat on it throughout the day and night. By the time I throw them the next bale in the morning they are just cleaning up the scraps from the last bale.
I have never had to put this much weight on a horse before. I was wondering what type of grain/supplements you would recommend and in what quantities.
