Cattle as well as sheep and goats may be infected with parasitic nematodes of fallow deer under natural conditions, but heavy infections do not occur. Most nematode species were recorded in goats, cattle harboured the fewest number of species. The specific abomasal parasites of fallow deer (Spiculopteragia asymmetrica, Apteragia quadrispiculata, Skrjabinagia ryjikovi, Ostertagia drozdzi) were only seen in goats in greater number while both cattle and sheep were only poor susceptible. Capillaria bovis was observed in goats and sheep, cattle and sheep harboured Cooperia pectinata and Nematodirus roscidus. Oesophagostomum venulosum was recorded in cattle, sheep and goats. Oesophagostomum sikae was recovered only from fallow deer. Dictyocaulus eckerti was seen in fallow deer and in one cattle.
