title: Effect of levamisole treatment on lambing performance of winter housed ewes.
abstract: The value of levamisole treatment of ewes housed during the last 10 weeks of pregnancy was studied over four successive years in a lowland flock of 400 ewes. Levamisole treatment, shortly after housing in January, improved the live lambing percentage each year, by an average of nine lambs per 100 ewes mated. Birthweight of lambs was unaffected by the improvement in lamb numbers.
