LICE CONTROL – WHY IS IT IMPORTANT?
The body louse or biting louse (Bovicola ovis) is the most prevalent and economically important species of louse found on sheep in Australia.
The body louse feeds on skin debris and wool grease. The heaviest concentration of body lice is found along the sides of the sheep, from neck to flank. Body lice can also be found in the neck folds and shoulder areas.
Sheep infested with the body louse will attempt to alleviate the irritation caused by their presence by scratching, rubbing, biting and pulling at their wool.
This results in:
- Cotted (matted) fleeces
- Fleece discolouration (yellowing)
- Fleece derangement
- Cockle (pelt defect which downgrades the value of the hide)
- Reduced appetite and body condition
It is important that a lice control program is implemented to reduce these production losses associated with lice infestation.
