Animals That Can Drink Cow’s Milk
Lambs Scientific studies show that cow’s milk is fine for lambs, so long as you add the additional fat levels that they need. While standard, store-bought milk is ok, it’s far better to use whole, powdered milk.
Foals Foals can be reared on cow’s milk alone if you supply it with certain additives along the way. In order for a foal to get adequate nutrients from cow’s milk, you should mix 2% milk with limewater at a 2:1 ratio, add in dextrose via pectin, and calcium oxide.
Pigs Pigs are the lone animals on this list that can just drink cow’s milk straight until they have to lay down from overextended bellies without having any negative effects, short or long term.
Goats In terms of rearing a goat, milk straight from the cow’s udder is the absolute best and will work just fine for their nutritional needs. Powdered milk and store-bought milk, however, will need to come with additives in order to give the goat the appropriate nutrition it needs.
Puppies When it comes to puppies and dogs, they love the taste of milk and they can consume it, just not in large quantities. With puppies or fully grown dogs, cow’s milk can be served as a treat after dinner.
Common Rat Cow’s milk is capable of fulfilling up to 25% of a rat’s total diet. They have more lactose tolerance than most other animals but they still can’t take cow’s milk in enormous quantities. Even a rat can get indigestion and diarrhea.
Cats Cats can drink milk, but it might do them more harm than good. Veteran cat owners might already know this but cow's milk, a staple in most households, might cause “gastrointestinal distress” or tummy troubles to your feline companion, according to Purina.
