Pneumonia in Saskatchewan swine: abattoir incidence of intrathoracic lesions in pigs from a herd infected with Haemophilus pleuropneumoniae and from other herds

Can Vet J. 1981 Aug;22(8):244-7.

Abstract

A 1978-79 survey of the incidence of thoracic cavity lesions at slaughter had shown that the overall incidence of pleurisy in Saskatchewan swine was low (2%). Therefore, in the summer of 1979 a comparison was made between the incidence of pleurisy in a herd of pigs chronically affected with Haemophilus pleuropneumoniae pneumonia and in animals from other herds slaughtered at the same time. The incidence of pleurisy in control pigs (3.6%) was slightly higher than in the large scale survey but in the pigs from the Haemophilus infected herd it was almost four times as great (13.3%). In the same herd the survivors of a batch of pigs which had been decimated by more severe disease showed an incidence of 32% pleurisy. The economic implications of these findings are detailed and discussed.
