Estimation of Uptake of Digestive Tract Strongyle Larvae from Pasture, Using Oesophagus Fistulated Sheep

Three Merino of Arles ewes fistulated at the oesophagus were used in autumn and spring in order to assess their larval uptake on infected irrigated pasture. The rate of transmission (ingested/available larvae of digestive tract strongyle) was low when the pasture was heavily infected; it was not otherwise modified by environmental factors.
