So here's what's up. I own a 17yr old Holsteiner/TB Cross. She has always been on the skinnier side. You can always see a hint of rib no matter what I've tried feeding her so far. Her flanks are a tiny bit sunken in as well. We event at training level, and she's been pretty well conditioned, but we don't have any more events this year so she's had an easier workload. She's on a regular deworming schedule and is up for a fecal exam soon. If it helps to know, she's had two foals.
Right now she's on 24/7 turnout. About half of the time that's on grass pastures. The other half she's in a dry lot with Brome hay. She also gets 4 qts of Purina's Equine Senior morning and night.
Does anyone have any supplements, feeding strategies, or ideas to help me get a little more weight on her? I really don't like to be able to see much rib, and going into winter it starts to worry me.
