Mares— If you’re thinking about breeding your mare, proper nutrition is essential in order for her to be in good condition prior to breeding. It doesn’t even hurt if she carries a little fat, although it is of no benefit to her to exceed a body condition score of 7 to 8. Research indicates that the rate of conception is substantially higher for those mares in good condition versus mares that are too thin (below a body score of 5).
