I’m looking for advice from people who keep TBs outside in cold climates - I’m in Ottawa, Canada
Lifelong quarterhorse owner here. My current herd consists of 3 easy keeper QHs and a mini. A senior OTTB has just been added to the mix. She came from a farm where she’d been out on a round bale full time and was at just about a perfect weight. I put out multiple round bales for the first few months that she was here to reduce resource-guarding but she still lost weight. She’s not working but is fairly active in the field. I started her on Trimax and increased it very gradually to 3lbs twice a day. She’s been at that rate for about 2 months and I have seen a slight weight gain but I’d like her to gain a bit more weight as we go into winter.
The QHs have also gained weight so I’d like to stop with the free-choice hay. Muzzles are not an option for them because they pull them off constantly. It’s also not an option to put the TB in her own field. So I’m thinking I will start adding alfalfa cubes to the TBs grain and ration the hay.
I’m wondering if I should reduce her grain a bit if I am going to add alfalfa cubes? I will soak the cubes and increase them very gradually but I have no practical experience with hard keepers so I’m not sure if this amount of processed feed is a concern for risk of colic? She’s a fairly slow eater so bolting her food is not a problem.
