Abstract
The influence of stresses due to transport of beef cattle and their allotment to feedlots on trichostrongylid infection was studied. The greatest increases in worm egg counts and serum pepsinogen levels were seen at 5 h and 30 days after allotment. These apparently resulted from reactivation of arrested larvae which the animals ingested while grazing during late autumn at the breeding farm.
