Castration

In a herd very few males are used.
One bull is enough for a herd of cattle.
One billy goat is enough for a flock of goats.
Keep only the best.
The other males of the herd must be castrated.

HOW TO CASTRATE A MALE
Either remove the testicles (see page 15) or crush the ducts which connect the testicles to the penis. The animal husbandry service and the veterinary assistants have instruments for castrating bulls.

WHY CASTRATE MALES?
After castration they are quieter, they are not vicious, they put on weight more quickly, the meat is better. They cannot fertilize the females; in this way you prevent poor breeding animals from reproducing, and can leave them in the herd.

AT WHAT AGE SHOULD MALES BE CASTRATED?
Animals must be castrated when they are young, before they can breed. They grow faster. Their meat is better.
