We will assume that your mare is in good physical condition, has been dewormed routinely and has up-to-date vaccinations prior to breeding. All of these factors contribute to a healthy animal and increase your breeding success rate.
Once your mare is in foal, it is important to continue on a 60 day deworming program. Most of the dewormers currently on the market are approved for use in pregnant mares.Always read the labels of any dewormer before use.For any further questions consult your veterinarian.
Rhinopneumonitis(Rhino) virus can cause abortion in mares.It is recommended that pregnant mares be vaccinated at five, seven, and nine months of gestation to protect against abortion. All mares should be boostered with at least tetanus toxoid 30 days prior to foaling. This stimulates the mare to make antibodies which will be present in the mare's colostrum (the first milk she secretes) and will give the foal protection for
the first few months of life.
Your mare should be maintained with a good nutrition plan. A good quality hay and grain must be fed. Fresh water should always be available. Some people supplement with extra vitamins and minerals. If you are feeding a high quality hay and grain, this probably isn't necessary.
Your mare will eat more during pregnancy but resist the temptation of overfeeding her. A fat mare may have more problems during delivery than a fit one. Keeping your mare fit involves a good exercise program. It is important to see your mare gets regular exercise to keep her in shape.
