Horses are part of an ever growing industry, with over 600,000 horses in the UK, 1.4 million riders and 5 million people with an active interest in the equine industry*. Most people acquire a horse out of choice, so if you make this decision you should think carefully before going ahead. A horse needs lots of love and care, including regular worming, vaccinations and dental care. Owning a horse is time consuming and can be costly; not only will you will need to consider where you will keep your horse, you must also consider the ongoing costs of owning a horse which include accommodation, bedding, feed and healthcare.
In the unlikely event that your horse goes missing it is going to be very difficult for anyone to know who it belongs to, unless your horse carries some form of permanent identification. It is wise to get your horse microchipped or freezemarked, this will avoid heartache in the long run, should your horse go missing or is stolen.
Horses are herd animals, and thrive on being together with other horses. Don’t forget that your horse will need somewhere to graze, a stable for warmth in the winter time, a constant supply of water, feeding daily and regular exercise. It can cost hundreds of pounds a month to care for a horse, including accommodation, food, veterinary care and insurance; there will be other costs, including buying tack and rugs and extra livery charges when you go on holiday.
Horses can live into their thirties, over this time your horse will need lots of care and attention. Being able to provide all of this will ensure you and your horse make the most of your time together.

The pregnant mare - health and well-being
Most people have pre-conceived ideas about how delicate and fragile a pregnant mare can be. Well... in a natural setting the mare does comparatively well reproductively considering how relatively poor a mare's reproductive performance is compared to other domestic animals. Good management is essential, but being over-protective is not necessary!
How will my mare cope with pregnancy?
As with human pregnancy, the first few days are the most critical. During the first month, there is a 10-15% chance that the embryo will be resorbed. Early embryonic loss can be caused by the following problems:
- Uterine infection
- Hormonal abnormalities
Following conception, the pregnancy can be confirmed by ultrasound or transrectal palpation at approximately 30-35 days. It is wise to have this re-confirmed at 45, 60 or 90 days.
From here on in, regular deworming, vaccinations, exercise and a balanced diet will help ensure a healthy pregnancy and successful birth.
How can I help make the pregnancy successful?
Good brood mare management is essential for a successful pregnancy. Your mare should be fit and possibly gaining weight. Avoid stress as this can cause a decrease in progesterone which helps maintain pregnancy. Illness and/or fever can cause the mares system to secrete prostaglandins which may cause abortion. The DO's and DON'Ts:
- Provide nutritious forage
- Feed a balanced diet
- Vaccinate and deworm regularly
- Continue with regular hoof and dental care
- DO NOT:
- Transport your mare unless essential
- Administer hormones or other drugs unless prescribed by your vet
- Expose your mare to other horses if there is a risk of illness or injury
- Expose your mare to unnecessary or undue stress
During the first 7 months of pregnancy, you can treat your horse as you would normally, unless there are circumstances that do not allow this, eg malnourished mare, obese mare, etc.
The weather should be taken into account as this could have an impact on amounts fed. She should have a continuous supply of clean, fresh water and her feed should include a high-quality forage. During the first 7 months of pregnancy, you should feed your mare as you have been doing previously, a balanced and healthy diet for her size and temperament. During the last 4 months of pregnancy the foal will start to grow rapidly. To accommodate this, the mares energy requirements will increase by up to 50% - good quality hay and forage should remain the main source of this energy, it isnt necessary to feed special nutritional supplements.
Concentrated feeds, eg grains, may need to be added to the feed to boost energy levels without adding excessive amounts of bulk.
Be sure your mare does not become obese - this will only become a disadvantage to her.
Your mare should be kept up-to-date with her course of vaccinations against tetanus and flu. This is important as infectious diseases can trigger abortion. It is good practice for your mare to have a booster vaccination 4 weeks before foaling, the concentration of antibodies to these infections in the first milk (colostrum) will be significantly increased and the foal will obtain immediate protection as soon as it suckles.
It is also advisable to have your mare vaccinated against Equine Herpesvirus (EHV) at the 5th, 7th and 9th months of pregnancy. If a mare is affected by EHV she may abort in late pregnancy or give birth to a weak foal that may die in the first few days of life.
Some studs also recommend vaccination against Rotavirus at the 8th, 9th and 10th month of pregnancy. If a foal is affected by Rotavirus, it will cause diarrhoea, but if the mare is vaccinated the foal will be provided with immunity via the mare's milk.
Generally, pregnant mares are wormed every 60 days. Most wormers available today are safe for pregnant mares, it is, however, wise to consult your vet to establish an effective and safe worming regimen for her.
In late pregnancy a mare's natural resistance to worms is lowered, so it is even more important that she is wormed at this time as she will be the primary source for infecting her foal with parasites.
Foot and dental care
Most brood mares are left unshod, which means that regular trimming at 6-8 weeks is important to prevent foot abscesses which are common in mares with overgrown feet.
Dental care is also very important. Your mare should have her teeth checked at least once a year, if not twice yearly. She will be able to utilise her feed with maximum efficiency and without discomfort. It is advisable to have her teeth checked at the time of the 1st pregnancy check.
What else do I need to know?
In horses the average pregnancy (gestation period) is 342 days (approximately 11 months) but can range from 321-365 days. Prolonged gestation is not generally a problem, but if you are concerned, ask your vet to examine your mare to determine if she is still pregnant and confirm that all is going well.
Continuing exercise is essential. Mares can be ridden lightly for the first 4-5 months of pregnancy, after then a pastured mare will get as much exercise as she needs while grazing. Regular paddock exercise in late pregnancy is essential. Vigorous exercise, however, is not recommended at any stage of pregnancy.
Mares do occasionally abort:
- If you notice any vaginal discharge or dripping milk during pregnancy, call your vet.
- If you find remains of a placenta or foetus, put it to one side for your vet to examine - it may be possible to find out the cause of abortion and treat the mare accordingly.
- Mares can abort without ill-effects; however, you should always have your mare examined by a vet just in case there are complications, eg retained placenta, which can be life-threatening.
