The present investigation showed that strategic feeding of first-season calves with the microfungus Duddingtonia flagrans through the initial 3 months of the grazing season could prevent severe clinical trichostrongylidosis in the late summer. The successful prevention of disease was particularly noteworthy in view of the high stocking rate practiced on this permanent pasture, which was widely contaminated with a range of gastrointestinal nematodes. The results showed that larval populations of Ostertagia and Cooperia were significantly reduced on the pasture grazed by the fungus-treated calves. Numbers of Nematodirus seemed less affected. The present paper discusses the complexity of fungus-nematode interactions in dung pats under natural conditions.
目前的调查表明，在放牧季节的最初3个月对第一季犊牛进行战略性投喂微真菌达丁顿孢子虫，可预防夏末严重的临床毛圆线虫病。鉴于该永久牧场的高载畜率以及广泛受到多种胃肠线虫的污染，成功预防疾病尤其值得注意。结果表明，经真菌处理的犊牛放牧的牧场中，奥斯特他线虫属和古柏线虫属的幼虫数量显著减少。细颈线虫属的数量似乎受影响较小。本文讨论了自然条件下粪便中真菌与线虫相互作用的复杂性。
