Van Es, L. and Martin, H.M. (1925) An inquiry into the cause of the increase of tuberculosis of swine (Research bulletin: Bulletin of the Agricultural Experiment Station of Nebraska No. 30)


ISSN 0097-1361


The great increase in the number of swine found to be tuberculous presented a problem, the solution of which appeared to be desirable before adequate control measures could be devised or recommended. In the hope that a solution of the problem may be found this station undertook an investigation and attempted by experimental inquiry to determine the infection type of the tuberculosis associated with the animals which constituted the bulk of the retentions. In view of the apparent increased incidence and spread of tuberculosis among poultry in a large hog raising section, of which Nebraska forms a part, the experimental project mentioned was to a large extent so directed as to prove or disprove the hypothesis that avian infection may at least in part be held accountable for the great morbidity rate for tuberculosis among swine and its marked increase during the last fifteen years.
