Factsheet on Helminthosis (worm infestation)

Diseases is caused by worms which are internal parasites. The most common worms are of the following species; round worms (nematodes), tape worms (cestodes), and flukes (trematodes). These parasites suck blood from the host animal and also consume digested food from the intestinal tract. The animals then suffer loss of nutrients and blood resulting in anaemia, diarrhoea, bottle jaw, weight loss, rough coat, hair loss, sudden death especially in young ones. The diseases occur in all ruminant livestock but the most affected are sheep, goats and calves.

Routine deworming of livestock using an appropriate dewormer. Rotating night bomas and grazing fields to avoid worm build up. Selection of worm resistant animals. Start by grazing young animals before the mature ones in the grazing fields. Remove manure and clean the bomas to avoid contamination of drinking water.

Routine screening of the animals by taking faecal samples to laboratory to be examined for worm eggs.

Direct Control
Routine deworming of livestock using an appropriate dewormer.

Avoid communal utilization of pastures and drinking points where pastures and water might be contaminated. Avoid under dosing with dewormers to avoid drug resistance.
