Ewe abortion risk

A SURVEY OF 221 farms shows more than half of UK flocks are still at risk from enzootic abortion and two-thirds have been exposed to toxoplasmosis, says animal health company Intervet.

Its FlockCheck survey examined blood samples representing about 120,000 sheep, across the UK. The results show infectious abortion is still a significant problem, says Intervet large animal vet Alasdair King.

He recommends producers investigate any flock where the abortion rate is 2% or more, with the costs of abortion put at 60-100 a case. “Blood tests will identify the causes and allow measures, such as vaccination, to be considered.”

Invervet is offering free checks to flocks of 100 ewes or more until the end of July through local vets.
