After you have completed your weight reduction diet, you go on a maintenance diet. This is similar to what owners should do for their broodmares during pregnancy. Pregnant broodmares need only a maintenance ration during the first eight months of pregnancy if they are in proper body condition. So, at this time of year, many broodmares have only a maintenance feeding requirement.
Maintenance has two parts.
The other element in maintenance is normal activity. A broodmare's grazing or walking to get a drink of water is considered normal activity. Running and bucking across the pasture when she is turned-out after being stabled all night is also normal activity. Exercise or performance imposed by you is not included in the normal activity component. If you are riding a pregnant broodmare regularly, a maintenance ration is not adequate.
