Feeding foals, weanlings and yearlings
Tania Cubitt | 18.10.20Fewer topics in equine nutrition stir more controversy than feeding the growing horse. Many factors add to the confusion of providing nutrition throughout these critical stages of life. For example, growing horses may have different commercial end points. Some will be shown in halter futurities where maximum growth and condition are required at a young age. Others will be prepared for sale, again requiring a “well-grown” individual and many will be kept on the farm to be used as replacement horses or future performance horses. These horses often have less pressure on them to look their best at a young age. A healthy foal will grow rapidly, gaining in height, weight and strength almost before your eyes. From birth to age two, a young horse can achieve 90 percent or more of its full adult size, sometimes putting on as much as 1.5kg per day. Feeding young horses is a balancing act, as the nutritional start a foal gets can have a profound effect on its health and soundness for the rest of its life. As the foal’s dietary requirements shift from milk to feed and forage, your role in providing adequate nutrition is vital. The critical nutrients for growth are protein (amino acids), minerals and vitamins. Nutrition imbalances have been recognized as one potential cause of growth disorders in young growing horses. Therefore, it is important that the diets of young horses be properly balanced with nutrients known to be vital for optimum development.
When you plan a feeding program for your young horses, several important factors need to be considered:
- Body changes involved in growth,
- Nutrient requirements of that particular breed of horse,
- The feed’s nutrient content,
- Anatomical limitations of a young horses’ digestive system. For example, you cannot feed young horses’ low-energy, bulky feeds because their digestive tracts are not large enough. Instead, young horses need concentrated sources of energy, protein, vitamins and minerals to meet their nutritive needs.
The Nursing FoalFoals will meet their nutritional requirements in their first 2-3 months of age from the mare’s milk and pasture. If a foal and mare are in good condition, the foal does not need to start creep feeding until it is at least 2 months old. However, some may need to start creep feeding by 30 days of age. In the third month of lactation the mare’s milk production drops while the foal’s nutritional needs keep increasing. Therefore, foals have a nutrient gap. Creep feeding (that is, using feed that the mare cannot get to) can provide the foal with extra nutrients to fill this gap.
Several aspects of creep feeding are very important:
- Start creep feeding when foals are about 8 to 12 weeks old. Make sure the feed is fresh daily and that foals are consuming it adequately.
- Use a creep feeder designed so that mares cannot gain access and so that foals will not be hurt. If you do not want a field type feeder, you can tie the mare in her stable, allowing the foal to eat.
- Put the creep feeder where mares gather frequently.
- Feed the creep feed at a rate of 1% of the foal’s body weight per day (max - 1 kg/100 kg of body weight).
- Choose a feed that will be easy for the foal’s baby teeth to chew.
