Not really, no. Calves should be eating plant-type feed, not insects or insect larvae.
Rhino calves in Africa can be killed by lions, hyenas, leopards, and African wild dogs. In Asia, predators include leopards and tigers. However, mother rhinos usually protect their calves effectively.
That's not the bull's responsibility, nor his job. His job is to get those calve's mothers bred to have calves again, not to feed the calves. The cows themselves are the ones responsible for feeding their calves via milk from their udders and teaching them what's good to eat and what isn't.
