I'm wondering if anyone has some practical advice for feeding my 32 year old Standardbred mare? She has never been a fat girl, but now it is difficult to keep her weight up. Right now she is out 24/7, but in the winter she comes in at night. She gets a senior feed plus performance horse feed (vet recommended this for the fat content) twice a day plus supplements. When the pasture is not optimal, there are round bales set out for the horses. She is out with 3 other mares and the little herd is peaceful. Her vet care is up to date, including teeth. What can I give her so the winter is not so hard for her?
P.s. She is fully retired and is everyone's darling at the barn.
