Any that’s the hypocrisy of Vegans. Milk and honey are the only two animal-based food sources that don’t involve the killing of animals. And in the case of most cow breeds, milking is actually needed as they have been bred to produce far more milk than their calves drink. And with careful management of the hive, you can harvest a lot of honey from a mature hive without negatively affecting the hive itself - it just delays/defers new queen production and swarming, which is desirable anyhow - no beekeeper who has hives primarily for crop pollination wants to have hives swarming each and every year.
