Is cows milk poisonous to elephants?

Cows' milk is not poisonous to elephants, but it can cause digestive problems because elephants are not adapted to digest lactose, the sugar found in milk. Lactose intolerance can cause bloating, diarrhea, and abdominal pain. In addition, cows' milk does not provide elephants with the nutrients they need, such as vitamin C and iron. Therefore, it is not recommended to feed cows' milk to elephants.
