Trichostrongyle worm infection in cattle: Ostertagiasis and concurrent infections in dairy calves: Seasonal patterns of occurrence, pathology and diagnosis

Abstract

Extract In a recent field study, Brunsdon (1968) Brunsdon, R. V. 1968. Trichostrongyle worm infection in cattle: ostertagiasis — effect of a field outbreak on production, with a review of the disease syndromes, problems of diagnosis and treatment. N.Z. vet.J., 16: 176–187. [Taylor & Francis Online] [Google Scholar] showed that ostertagiasis in dairy calves is a potential source of considerable economic loss to the livestock industry. This work has highlighted the deficiencies in the knowledge pertaining to this and other trichostrongyle infections in cattle under New Zealand conditions. Furthermore, the existing parasite problems in cattle are likely to increase as a result of the current expansion of the dairy beef industry.
