Control of strongylosis in horses by alternate grazing of horses and sheep and some other aspects of the epidemiology of strongylidae infections

摘要: Alternate grazing of horses and sheep as a control measure for gastrointestinal helminthiasis was studied in three experiments 1981, 1982 1983. Each year group mare yearling Shetland ponies, which were kept on small pasture from spring to autumn, compared with similar grazed or the same until July subsequently removed had been by April July. In addition both groups treated an anthelmintic when latter pasture. Pasture larval counts worm and, 1983, faecal egg counts, clinical condition, total protein, albumin beta-globulin levels demonstrated that acquired considerably lower burdens nematodes subfamilies Cyathostominae Strongylinae, but higher Trichostrongylus axei than not moved. These T. infections resulted serum pepsinogen former 1981 1982. At necropsy important part consisted inhibited early third stage larvae. A 20 species subfamily 7 Strongylinae found. Generally composition agreement other observations western Europe, most common being: Cylicostephanus longibursatus, minutus, calicatus, goldi, poculatus, Cyathostomum labratum, coronatum, catinatum, Cylicocyclus leptostomus, nassatus, insigne, Strongylus edentatus vulgaris.
