Why do humans need to eat plants and fruits to be healthy, but large carnivores (Tigers, Lions, etc.) don’t?
In: Biology
So for orcas (killer whales) for example, aquariums used to order and feed them filleted pieces of fish. And they wouldn’t understand why they’d keep getting infections and need antibiotics.
Later they started giving them whole fish. There’s a lot more minerals in the other parts of the fish, particularly the skeleton and perhaps also the brain IIRC.
That didn’t eliminate infections but it did reduce them.
Large predators are really well evolved. As long as they can access their natural food sources, they usually get the nutrition they need. That and sufficient genetic diversity are their keys to not getting seriously sick.
