Remember, all foals should have access to fresh water at all times. What To feed The next question is what type of milk should be fed to the foal. Mare's milk is the perfect solution, as it alone matches the nutrient needs of the foal. Otherwise, milk from other animals can be used. Goat's milk can be fed without alteration, but is more expensive than cow's milk.
Some foals prefer the taste of goat's milk over cow's milk.
Commercial milk replacers can be used and are a convenient and very acceptable alternative to mare's milk. Several formulations specially for the foal now are available, and these are the most desirable. This is by no means a complete list, and other foal milk replacers are perfectly acceptable. Calf milk replacers also have been used to raise foals successfully. However, many calf milk replacers contain antibiotics, which should never be used in foals.
