Prevention And Control Of Parasites
Overview
Every farm animal will meet parasites: worms in the gut, ticks on the skin, flukes in the liver. The farmer who waits for signs of infestation before acting has already lost weight, milk and sometimes an animal. The farmer who plans ahead, and who still knows how to act firmly once an infestation appears, keeps a healthy, productive herd or flock all year round.
In this lesson you will learn the difference between prevention, the everyday management that keeps parasites out or keeps their numbers low, and control, the direct action taken once an infestation is already present. You will meet the specific methods WAEC expects for each, learn how drugs are used correctly in parasite control, and see why the best farms treat prevention and control not as separate jobs but as one continuous cycle of watching, acting and reviewing.

- State the methods of preventing parasitic infestation in farm animals
- State the methods of controlling parasites in farm animals
