Castration normally causes an increase in body fat and meat, and the castrated animal becomes obese (perhaps a FABULOUS MONSTER),「getting started, foundation」for large profit when sold.「Cattle with same motion again」as perhaps as first reaming or slicing off one testicle, and then the other…yet, it seldom is as simple as that. Most bulls「will not stand for」emasculation, in fact by lying down. Ranchers with experience will mostly concur that emasculating a bull while a ton of meat is resting atop the testicles is a difficult task. A bull, particularly after the first incision, is also likely to charge the knife and attempt to gore, stomp upon, kick the human wielding it, or, instinctively run like hell away as fast as possible. So, the key to this process is for「cattle to stand erect」and devise some system or contraption with a「base, foundation」of both binding and support to maintain that posture and not get kicked whilst slicing off the animal's gonads, or permit the animal to crush the veterinarian. Needless to say, chances of success increase the younger the bull is when becoming a steer, therefore castrating an adult bull is not generally recommended. Tetanus, undescended testicles, bleeding out, localized infection, depression, the mother cow nearby, slicing one's own fingers in the process, and maggots each can also become a nuisance.

Foundation for building a harem of herd meat assets consists of starting with a CASTRATED EUNUCH as managing director. A「herd of meat as a currency basis」kept in a harem for use by the owner/lord can best be managed using a「foundation, base that is constructed」of a managerial team comprised of all eunuchs, castrated human males with a diminished natural desire to sample the wares (but not totally eliminated, just under more intelligent control rather than, say, that of a twice-daily fist-pumping adolescent). Led by a「fearless leader of a fearless tribe」but lacking testosterone produced by the eunuch's own body (testosterone may continue to be ingested, however. Fish sperm is still a treat in Japan today). Fearlessness in a fearless leader of a fearless tribe of eunuchs managing the lord's harem would not be due to any lack of testosterone—quite the contrary: since a lack of testosterone would result in sterility, a eunuch could and can physically achieve an erection, engage in sex and enjoy it, but with no fear of impregnation or conception within the herd, becoming in one sense a FABULOUS MONSTER to do as he pleases at will among the land's finest prime meat.
