So thank you for taking the time to read my thread in advance. So many knowledgeable people here, I know I'll get some great advice.
For starters, I'm a first time horse owner had been leasing for about a year and decided to jump in full hearted. Found a horse for sale that had been rescued from terrible condition. That being said, I felt comfortable picking up a horse that had 6 months of rehab under her belt. (She had been terribly emaciated and her feet are still growing out some terribly splayed hooves. Had some hoof wall separation but I'm cleaning daily and using coppertox to keep them from getting thrushy). All in all, she's a health and happy mare. She's 11 years old, so was able to bounce back well with good care.
She's had her first worming with me, started with Ivermectrin and found a rotational deworming chart online:
Deworming Rotation Schedule and Worm Facts
I'll be deworming with Safeguard next (I've had GREAT success with this one on my dogs--same active ingredients)
Anyways, she's 15.3 1/2 hands, just under 16 hands high. A big gentle giant. She is (per my weight tape) about 916lbs. Very thin still. I didn't get her weight when I got her two months ago, totally should have. My understanding is that she should be in the ballpark of 1100-1200 lbs.
The barn has her on 2 flakes alfalfa in the morning and 2 flakes of oat in the evening I believe. I've been doing one big scoop (not a lot, didn't want to make her hot or initiate other health issues) of all in one (alfalfa shredded with molasses) with her one big scoop of biotin plus for her feet. I don't think this is going to help her weight and I've spoken to the barn about adding STABLE FEED (Mix of forage grasses, vitamins and a well balanced feed without molasses) to her diet and taking out the all in one.
My question is this. I would like her to gain at least those 200lbs.
1. How much time should she gain this weight? I'm hoping to get it on her before the winter comes--or is that too fast?
2. How many pounds per day (of low sugar feed) should I add to her current morning and evening ration of hay? I don't want to overfeed her and make her sick--which is why I'm staying away from heavy grains and alfalfa and molasses.
Thank you all, this is a fine, fine community of knowledgeable horse people!!
