Nematodirus warning as forecast shows hatching now at seasonal peak

This disease is best prevented by keeping the current year’s lambs off any pasture that was grazed by lambs or young calves

Sheep farmers have been reminded to treat at-risk lambs as the Department’s 2022 Nematodirus forecast shows most parts of the country will now be in peak season for Nematodirus egg hatching.

At-risk lambs (typically those aged six to 12 weeks and grazing on contaminated pasture) should be treated approximately two weeks after the peak of Nematodirus egg hatching.
