The risk of benzimidazole resistance must be borne in mind in any worming strategy. A policy of 2 year rotation of benzimidazole and ivermectin products is currently practiced.
Risk of worm larvae on pasture should be taken into account where possible. Young lambs should not, if possible, be grazed on the same pasture as the previous year's lamb, crop. However, pressure on grazing at Lackham makes this impractical.
MAFF forecasts for risk of Nematodirus outbreaks may alter any pre-determined worming schedule, but normally 3 doses at 3 -week intervals should be given during May and June.
Towards the end of June lambs should, if possible, be moved to clean grazing
to avoid the late summer build up of the other helminth larvae.
If clean grazing is not available, prophylactic doses of wormer should continue
to be administered through until autumn or marketing.
Ewe & ram worming
See lamb section re 2-year drug rotation.
Ewes must receive a dose of wormer in the last month of pregnancy and again within the first month after lambing (if using benzimidazoles)
Fluke treatments should be considered where sheep have grazed wet pasture especially during the ivermectin year. The dose can be increased to cover fluke during the benzimidazole year.
