Study on the causes of outbreaks of lungworm disease on commercial dairy farms in The Netherlands.
The causes of outbreaks of lungworm disease were determined from the herd histories of 25 affected herds of young cattle. The results indicate that light pasture contamination by carriers and subsequent auto-infections are the most prominent cause of lungworm disease, followed by heavy pasture contamination by carriers. Overwintered pasture infections seem to play a minor role. Adult dairy cows seem to be the predominant carrier animal when light pasture infections are concerned. Heavy pasture infections are almost always caused by calves and yearlings.
