Body Condition Scores in Horses
(Brood mares)

Fat Deposition Sites

The condition (amount of body fat) that horses are kept in will depend on the class (sex and age) of the animal, as well as the owner=s plans for that animal. In terms of brood mares, a minimum body condition score (BCS) of 5 is recommended for dry mares entering the breeding season, and BCS=s ranging from 6.5 to 7.5 are recommended for mares that are entering lactation (foaling). The mares that tend to produce more milk and that are easily drawn down (i.e. those that lose condition easily) need to be in the Afatter@ state at the time of foaling. Mares should be expected to lose some condition while nursing and to be near a BCS of 5 at time of weaning. The stored body fat serves as an energy reserve to help meet the high energy needs of milk production.
