STUDY ON THE INFESTATION OF A PASTURE FOR FARMED FALLOW DEER (DAMA-DAMA L) WITH LARVAE OF GASTROINTESTINAL NEMATODES AND LUNGWORMS AND LUNGWORMS

Herbage samples were examined for larvae of parasitic nematodes from M ay to November 1993 in fortnightly intervals in a fallow deer farm nea r Leipzig, Saxonia, Germany. Third stage larvae were present during th e whole study period on pasture. From May to June only a few larvae of ostertagians were recovered. With the rapid rise of larval counts in June larvae of Oesophagostomum spp, appeared on pasture. Larvae of Nem atodirus roscidus were seen from the end of July until November and re ached a peak level in September. After increase of pasture larval coun t in June it remained on a low level until November and varied between 76 and 152 larvae per kg dry matter herbage. Dictyocaulus larvae were recovered from herbage in small numbers in autumn from September to N ovember. The investigations show, that no dangerous pasture larval cou nts were observed despite of a high stocking rate of about 20 fallow d eer to the hectare.
