Abstract
There is unequivocal evidence that sheep can acquire immunity to gastrointestinal nematodes. In Western Europe, for example, while clinical parasitic gastroenteritis is common in lambs during their first grazing season, disease outbreaks are unusual in subsequent years. It has been shown experimentally with three different species of nematode that substantial immunity to incoming larvae develops after about 2 months in continuously infected lambs (Barger, Le Jambre, Georgi and Davis 1985; Fig. 1).
