A Field Experiment on Rain Splash Dispersal of Infective Larvae of Ostertagia Ostertagi (Trichostrongylidae) from Cow Pats to Surrounding Grass

摘要

Ostertagia ostertagi is an important tricho-strongyle nematode parasite of cattle in several countries, including Denmark. It leaves its host as eggs with faeces. After hatching it develops in the cow pat up to the third and infective stage, which is then transmitted to the surrounding grass.
