The pupal stage usually lasts 9 to 10 days. After the adults emerge, they live an average of two weeks. During her lifetime a female moth will lay 3 to 5 egg masses each containing from 100 to 150 eggs. The kindest cut may be the one made at a young age, when it comes to castrating beef cattle. Scientists in the ARS Livestock Behavior Research unit at West Lafayette, Indiana, found calves castrated shortly after birth suffered less stress and recovered faster than those castrated around weaning time.
Farmers remove their calves' testicles to reduce aggressiveness in male animals as they mature.
Meat from uncastrated cattle can be tougher and may carry an unpleasant odor. The West Lafayette lab studies livestock behavior in order to gauge the stress level in animals.
