Goats eat mostly grass, hay, weeds, grains, and other roughage. They have complex digestive systems made up of multiple stomachs designed to break down foods that other animals can’t eat.
Yes, feeding blueberries to goats is no problem at all. Your goats will love eating them and they actually provide some excellent nutrition for them.
When a goat sees something like a strawberry or a blueberry, they know it is higher in calories and sugars, so they’re going to want to eat it.
Blueberries and other fruits should be used as an occasional treat, not as a staple in your goats’ diet.
