Sheep are extremely susceptible to parasitism by nematodes. Their gregarious nature and characteristic grazing habits expose them to an unusual amount of infective material. One family of nematodes, the Trichostrongylidae, has been particularly successful as parasites of ruminants. Several management systems involving moving animals from one paddock to another in an attempt to avoid ingestion of the infective stages have been evaluated over the years.
In the following experiment lambs maintained in pens with no vegetation and fed in troughs raised off the ground had an insignificant number of parasites, while grazed lambs became heavily parasitized.
