Prevention And Control Of Parasites

Gbogbo ọrọ náà

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.

A herder near Sokoto notices his cattle scratching against fence posts and losing condition despite good grazing. By the time he calls a veterinary officer, the animals are carrying a heavy tick burden and several are anaemic. A neighbouring herd, inspected weekly and dipped on schedule, shows none of this. The difference between the two herds is not luck. It is whether prevention and control were practised as routine management or ignored until the damage was visible.
