Livestock Health
Overview
A sick animal eats but does not grow, costs money to treat, and can pass its illness to the whole herd before the farmer even notices. Keeping livestock healthy is therefore one of the most valuable skills in farming, and most of it is prevention rather than cure: a good stockperson spots the first signs of ill health early, knows how diseases and parasites spread, and stops them before they take hold.
In this lesson you will learn to read the signs of health and ill-health in an animal, to explain how infectious and contagious diseases spread and how parasites harm livestock, and to understand why some diseases must be reported to the authorities. You will see how hygiene, clean water and the isolation of sick animals break the chain of infection and keep a herd or flock productive.
