Extract

Control of parasitic nematode infection is the first priority in intensive lowland lamb production. The most effective method has been the ‘clean grazing system’ of Rutter (1983) but this depends on the integration of cattle and sheep. Clarkson (1987) has proposed repeated early dosing with anthelmintic as an alternative in an ‘all sheep’ system. An experiment is decribed here in which the efficacy of the anthelmintic. Mebendazole (Janssen Pharmaceuticals Ltd), was examined using different dosing regimes on contaminated pasture and compared with clean pasture.

The study was conducted with a flock of 520 mule (Bluefaced Leicester x Swaledale) ewes and Suffolk x lambs at Home Farm, Wytham, near Oxford. Four x 8 hectare fields were used.
