title: A model for predicting parasitic gastroenteritis in lambs subject to mixed nematode infections.
abstract: A model previously developed for the prediction of parasitic gastroenteritis in lambs arising from infection by the nematode parasite Ostertagia circumcincta has been adapted to consider mixed infection and retested. The importance of the lambs as a contributing source to the summer wave of infective larvae is highlighted as are certain apparent deficiencies in the use of grass sampling techniques as a means of assessing pasture larval contamination.
