Western Kenya Tea Zone
Typical Problems In This Area
1. The weather conditions are suitable for
transmission of stomach and intestinal worms throughout the year, so worm
numbers can be high.
2. Because of the relatively cool conditions at this altitude,
pasture can remain infective for long periods after it has been last grazed.
3. Liver fluke is present in valley bottoms.
4. SEVERE RISK OF ANTHELMINTIC RESISTANCE.
Features Of The Area That Can Help In Control
1. Farms are often larger than in other areas, so it
can be possible for farmers to manage rotational systems.
2. Cattle are often present in numbers which can permit
alternate grazing systems to be effective.
3. Rapid grass growth can enable cut and carry systems of animal
feeding to be effective.
Control Methods That May Be Useful
observation of individual animals and treating only clinical cases.
· Adult cattle can graze areas
after sheep, goats or calves in an alternate grazing system.
· Fresh grass grown after a crop
has been harvested will be clean. A rotation of cropping and grazing areas can
provide constant availability of clean grass (Cropping Rotation).
· Medicated feed blocks can be
made with locally available ingredients and provided to the animals overnight in
· Cut and carry systems can
prevent animals grazing and contaminating pasture.
· GUIDELINES FOR USE OF
ANTHELMINTICS SHOULD BE CAREFULLY FOLLOWED TO SLOW THE DEVELOPMENT OF
