how to get horses to gaine weight

What are the best feeds to feed a mare that has a foal on her? The pair we have gotten a few months ago came to us well the mare came to us pretty skinny, i'd say she cold gain easy 150. And how much!!?? I was feeding an amount was told that was too much but everyone else says it is not. 3 qts in the morning and 3 in the evening. I work so a 3rd isn't possible. I'd love to though. I live way out so I don't have anyone that could just run out to the house and give an extra feeding. I give lots of hay. As much as they can eat. The hay here isn't very good. Just mixed coastal. We are lucky to have that right now. It was a really bad year around here!!

As for you mare being thin, the amount of grain sounds fine. All the hay they want is good. Can you get your hands on stuff called hay stretcher? It would be good to add to your grain feeding morning and night seeing your hay isn`t the best. Also make sure they have been wormed really good. Even if you have to do it every two weeks for a month straight.some horses just need more worming then others.
Good Luck.

My mare has had the crap wormed out of her poor girl the man that had her did not realize she had come and and was bred. He though hr swollen belly and rib show was from a bad case of worms!! Idiot!! She was pregnant and went all summer scrounging around in the pasture for whatever she could find. I will check into the hay stretcher also I have heard of alfalfa bags I can get from my vet. Are they good?

With him not knowing she was bred he could of killed the foal by worming her.you have to be careful on what wormers you us on bred mares. Alfafa is good.alot of people feed it. It is high and very rich in protein. But I wouldn`t recommand feeding alot of it.
Check around at your feed store and see what you can find for a under weight horse.also check with other horse people in your area.
Good Luck.

What others have told me around here is all the hay they can eat and alfalfa pellets, beet pulp, and rice bran and corn. I am not feeding the corn but the others I am. She has stopped loosing and even gained a little since here but with a 5 month old filly on her she can't gain. I am hoping to have her completly weened soon. I see her sometimes pushing her away or pulling up her leg so she can't nurse and every time I see her nurse I give a no sound and she knows I mean quit. And she does. She is very smart the little booger!! I hope to have them seperated more so I can work with mom more. She is not broke yet and actually hasnt any maners or respect so we are trying parelli. Jewels is doing pretty good with it and I am too. But with baby right beside us it is hard and tinker crys when she is away from her.
