Conteúdo: 	The development of internal parasites in weaned lambs was examined under two grazing systems in two consecutive years. Lambs were grazed either on pastures not grazed by lambs in that season and later on pastures not grazed by lambs in the previous 12 weeks, or on pastures already grazed by lambs continuously in that season. Parasitism, as indicated by faecal egg count, developed similarly in both treatments and no difference in lamb liveweight gain was observed.
The results can probably be attributed to a lack of real difference in larval contamination resulting from the grazing treatment and, in the first year, to the drenching schedule adopted which gave more protection to the second treatment.
