I have read many posts on feeding our mares in waiting..but I do have a question that is really bothering me and maybe someone can help. My little mare, 31" has a funny shape to start with, carries a heavy lower neck/chest..(Dolly Parden with 4 legs)...I have read soo many posts on the amounts the mares get and I am afraid she would blow up, if she ate that much. She gets 1 cup 2xs a day of 16% plus coastal hay. She is in a smaller pasture but Texas is dead and dry. I have added today 1/4 cup of a milk based supplement sorta like calf manna...she was on BOSS but I stopped that because of her weight. She seems to be one of those mares that stays fat on air, but I also want her and the baby healthy. It scares me to death that she will have problems birthing, but , heavans, I know you cannot NOT feed them.......she has hills she walks up and down daily...and is put up at night....??????? This is her 6th foal.
