You've been antcipating the arrival of your new foal for some time. And now, here he is. Shortly after hitting the ground, the new foal will stand and nurse. This is of critical importance since the foal receives the anti-body-rich colostrum that helps protect it from disease. During the first weeks of life, the mare's milk provides all the nutrition the foal needs for sustenance.

Nursing is critical for newborns

Nursing within the first few hours is of critical importance since the foal receives the anti-body-rich colostrum that helps protect it from infection. Colostrum also creates a mild laxative effect that helps the foal pass the meconium. The meconium is the first stool and is a thick tarry substance which can be hard to expel.

For the mare to provide the best nutrition, the mare needs almost double the amount of feed she required during pregnancy with adequate protein, vitamins and minerals, and plenty of water, not only for her own health but for the health of the foal.

During this early time period, the foals nursing habits should be observed carefully. If the foal is suckling for more than 30 minutes, it may mean that it is not getting enough milk. In this case, supplemental feed or milk replacer may be necessary for healthy development.

Some foals show interest in feed as early as 10 to 14 days of age. As the youngster nibbles and learns to eat solid food, its digestive system adapts to the dietary changes. This may bring on coprophagy (eating of feces) along with foal heat diarrhea as intestinal microflora changes. Research shows this to be a natural development occurring around days 6 to 14 and the foal usually quickly outgrows the diarrhea which is self-limited.

When the foal has diarrhea, it is important to keep the foal dry and clean around its tail and perineum. Zinc oxide may be applied to prevent scalding. If the diarrhea persists, some veterinarians recommend giving small doses of Pepto-Bismol (20 ml per 100 lbs weight) by syringe or tablespoon. Always check with your veterinarian before giving any medication or if the diarrhea worsens.

As the foal grows, his needs change, and by 8 to 10 weeks of age, mare's milk may not be sufficient to meet the foal's nutritional needs. At this point, high-quality grains and forage should be added to the foal's diet.  The feed should be properly balanced for vitamins and minerals since deficits or excesses, or imbalances of needed minerals and vitamins can lead to skeletal problems.

Since feeding a foal properly is a balancing act, here are some important guidelines to follow:

• Provide free-choice high grade hay and forage
• Supplement with high-quality properly-balanced grain concentrate
• Weigh and adjust the feed quantity based on growth and fitness
•  General rule to follow is one percent or a foal's body weight per day or one pound of feed per month of age
• Make sure feeds contain the proper balance of vitamins, minerals, energy and protein
• Divide the daily ration into two or three feedings 
• Use a creep feeder to separate the foal from the mare so it can comfortably eat it's ration
• Do not overfeed. Overweight foals are more prone to developmental orthopedic disease
• Provide unlimited fresh, clean water and the opportunity for plenty of exercise

Weaning your foal

Beginning about the third month, the mare's milk supply will gradually diminish and a natural weaning process occurs. At this time, the mare's grain should be reduced or gradually eliminated to help limit milk production, and the foal's ration should be gradually increased over a two to three week period.

Once the foal is no longer nursing, it is known as a weanling and should be eating approximately two to three percent of its body weight in feed and forage per day. Bone, muscle and mass will continue to build at a remarkable rate and from weaning to two years of age, the horse may nearly double its weight.

Watching a foal grow into a spry, healthy horse is one of the greatest joys of horsemanship. Yes, it takes hard work, plenty of planning, and adherence to the best management principles available, but the rewards are great for both you and your foal.
