When I had my dairy, my kids got fed twice a day, usually a 20 oz coke bottle, and they had access to alfalfa hay and grain. They got pasteurized goat milk or cow milk. Cow milk from the store works great. Some kids do fine on replacer and some blow up and die on it and there is no way to tell in advance which is which. I never found any difference between the expensive replacers made just for kids and premium calf milk replacers either. For the price of many of the kid replacers it is just as cheap to feed milk from the store. Since the milk from mini goats and Boer goats is higher in fat than the milk from most dairy goats, the following formula works very well for them. Take a gallon jug of whole cow milk from the store. Pour off about a quart into another container. Add a cup of buttermilk and a can of evaporated milk to the jug and shake to mix. Fill the jug back up with some of the milk you poured off. Shake again and it's ready to feed.
