Propetamphos pour-on formulation for the control of lice on sheep: effect of lice on weight gain and wool production.

Abstract

Infestation of sheep with the biting louse Damalinia ovis is a potentially serious problem which can effect the quality and quantity of wool produced and may reduce weight gains. In this trial treated sheep produced 34 per cent more wool than louse-infested controls and the wool from the treated sheep was of a better quality. The mean liveweight gain in the treated groups was 18 per cent more than that in the untreated group. Treatment with a pour-on formulation of propetamphos at 25 to 50 mg kg-1 gave more than 99 per cent control of lice and protected against reinfestation for four months.
