title: [Studies on the possible causes of cough in calves at pasture (author's transl)].
abstract: Respiratory disease occupies a prominent position in the series of common diseases in calves. Efforts were made to take an inventory of possible causes of cough in calves at pasture. For this purpose, a number of calves on twenty-three, ten and eight mixed farms respectively were clinically studied during the period from 1975 up to and including 1977. Faecal, sputum and serum samples were collected to examine them for the presence of husk worm larvae, husk worm eggs, antibodies to specific viruses and lung worms. In 1978, titres of antibodies to lung worms were determined in the serum samples of a large number of calves from forty-five farms. From the findings obtained, conclusions were drawn regarding the prevention of virus and lung worm infections in calves at pasture and regarding the diagnosis and prevention of verminous bronchitis in these animals.
