(introduction...)

Besides parasites that live on animals' skin or in their bodies, there are many diseases which prevent animals from growing and which may even kill them.

In the animal husbandry courses on chickens, cattle, sheep and goats, we shall deal with the diseases which each kind of animal may have:

· Diseases due to germs, such as anthrax, rinderpest, pox, pneumonia.
· Diseases due to bad feeding through lack of mineral salts (see Booklet No. 8, page 17).

An animal that is badly fed, badly housed, badly looked after, resists disease badly. It is often ill.

For animals to resist disease, a good farmer must: feed them well (see Booklet No. 8, page 10); give them clean water to drink (see Booklet No. 8, page 18); house them well (see Booklet No. 8, page 34); treat their wounds (see page 5).

A good way of controlling diseases is to protect the animals by vaccination.
