Hippocrates did exist (although some scholars dispute even this) and was well known in the Greek world. Apparently born about 460 B.C. on the island of Cos, he died about 370 in Thessaly. He was a teacher on Cos, an itinerant practitioner of medicine, and the presumed author of a number of treatises.
Males: Castration is a relatively minor operation, which can be performed as soon as the testicles descend (10-12 weeks) although most vets wait until the rabbit is 4-5 months old. The testicles are removed via the scrotum or the lower abdomen.p to 80% of unsprayed female rabbits develop uterine cancer by the age of 5. Females who are not spayed when young and in good health may have to undergo the operation as an emergency in later life (e.g. cancer or pyometra) develops.
Rabbit fryers are rabbits that are between 70 to 90 days of age, and weighing between 3 to 5 lb (1 to 2 kg) live weight. Rabbit roasters are rabbits from 90 days to 6 months of age weighing between 5 to 8 lb (2 to 3.5 kg) live weight. Rabbit stewers are rabbits from 6 months on weighing over 8 lb. Any type of rabbit can be slaughtered for meat, but those exhibiting the commercial body type are most commonly raised for meat purposes.
