Abstract
Extract This paper describes an experiment carried out to assess whether ewes exposed to hairy shaker disease in their previous pregnancy by contact with artificially infected ewes (Lewis et al., 1970 Lewis, K. H. C. , Porter, W. L. and Manktelow, B. W. 1970. Hairy shaker disease and abortion: immunity and transmission via mucous membranes. Vet. Rec., 86: 537–538. [Google Scholar] ) had acquired an immunity to the disease.
