DRENCHING sheep with drugs designed to eliminate parasites has become an established practice in the higher rainfall districts of Western Australia.
has been tested in many trials, and their is little doubt that drenching sheep clinically affected with worms—the so-called "tactical" drench—is valuable and necessary.
However, there is usually less general acceptance of the value of "strategic" drenching— the prevention of clinical parasitism by giving the drug at certain specific times, pre-determined by a knowledge of the numerical rise and fall of the various parasites within the animal body.
