[Use of anthelmintics for nematode control in sheep in West Germany: results of a survey].
A survey by questionnaires was performed on 543 (0.9% of all) sheep flocks in western Germany in 1988/89 to obtain informations about deworming practices against gastrointestinal nematodes. The major informations are: Anthelmintic treatments were associated with the reproductive status of ewes and the breeding of lambs in most of the flocks. They were performed at an epidemiologically appropriate time in many cases but were not accompanied by essential management practices. (Pro)benzimidazole compounds were the anthelmintics most frequently used by more than 95% of the farmers; 22% and 13% of the farmers additionally or exclusively administered levamisole/pyrantel and ivermectin, respectively. On average, treatment of ewes and lambs against nematodes was performed 2.5 times and 2.8 times a year, respectively. The mean frequency of deworming differed regionally and was generally greater in pedigree breeding flocks than in commercial breeding flocks; it was significantly affected by the husbandry system, the number of ewes per flock, the size of available pasture and the class of anthelmintics employed. The results of this survey revealed that many German sheep farmers obviously lack an awareness of the rationale of preventive and economic control practices against gastrointestinal nematodes.
