Worm warning as counts rise
Worm warning as counts rise
WORM counts are increasing and a further flush could be expected this autumn with the effects showing in lambs well into November.
Despite lower temperatures this week, parasitologist Gordon Graham warns that recent warm weather and rain will have increased worm burdens in sheep.
"Early autumn temperatures have been high enough to hatch eggs from all types of worms," says Mr Graham. He suggests looking for tell-tale signs of infection such as dirty back ends and weight loss.
"Dosing in some flocks will have to be continued to control worms before moving to stubble crops or clean grass if available."
Brian Preece, senior vet officer at Starcross veterinary investigation centre, Devon, suggests asking the local vet to formulate a worm programme.
"This programme should encompass this seasons grazing and the anthelmintic use for the year. Only then can an effective programme be developed at least cost," says Mr Preece.
He warns that when worm burdens are severe, lambs will be deficient in vital vitamins and minerals and supplementation will be needed.
then be stunted.
Vitamin B12 deficiency is particularly likely and Mr Preece suggests this could be injected directly into the bloodstream to help reduce the long-term effects of the infection.
