Castrating bulls

A herd of 25 cows needs only one good bull, a good breeding animal. The other males in the herd must be castrated.

A castrated male is called an ox or bullock.

· How to castrate a bull

Either remove the testicles (see page 43) or crush the ducts which connect the testicles to the penis. The animal husbandry service and the livestock assistants have instruments for castrating bulls.

· Why castrate bulls?

After castration bulls are quieter, they are not vicious, and it is easier to harness them. They put on weight more quickly, the meat is better. They cannot fertilize the cows; in this way you prevent poor breeding animals from reproducing, and can leave them in the herd.

· At what age should bulls be castrated?

At about 10 months if you want to sell them to the butcher.

At about 18 months if you want to make working oxen.

If you wait until 18 months, the ox is stronger for work, but in that case it must be kept away from the herd, so that it cannot cover the cows.
