title: The presence of gastric parasites in winter-slaughtered reindeer.
abstract: The presence of gastric parasites in winter-slaughtered calves and adult animals, was investigated. The number of parasites found was low in case of the calves indicating that gastric worms are of low significance concerning the winter losses. In case of adult animals was found a higher infestation indicating that gastric nematodes maybe of importance concerning the winter losses of 1,5 years old animals, Ostertagia leptospicularis was the only found species except for one animal in which was also present a few spiculopteragia alcis. The total dominance of Ostertagia leptospicularis means a marked difference from the findings of autumn-slaughtered reindeer bulls where Ostertagia leptospicularis was not found to be such a frequent finding but in addition several other species were found. In view of that is discussed a seasonal varation, winter ostertagiosis seems not to be a problem in reindeer calves.
