Abstract

Epidemiological studies carried out in 1979 near Chur and Arosa (Kanton Graubunden/Switzerland) showed the following: Third stage larvae of cattle trichostrongylids (Ostertagia, Cooperia, Nematodirus) can over-winter on high alpine pastures (2 000–2 400 m altitude) at least until mid June. Egg counts, serum pepsinogen levels and worm burdens of 6 tracer calves indicated that trichostrongyZid infections were subclinical in calves and cattle grazing at a low stocking rate (0.5 animals/ha) on high alpine pastures. At the end of the grazing period on high alpine pastures (mid September) 31% and 57% of two groups excreted Dictyocaulus larvae.
