An attempt was made to control Ostertagia ostertagi by feeding the nematode-trapping fungus Duddingtonia flagrans (DSM 6703) to grazing calves. One group of calves (group E) was fed the fungal material in the first two months of the grazing season while another group was a non-treated control group (group C). Group E showed significantly lower faecal egg count in August and September. On four occasions in July and September, the herbage larval counts were significantly lower on the plot with the fungal-treated group than those recorded on the control plot. The average abomasal larval and adult worm counts were significantly reduced in August in group E and the average total worm count in the abomasum of group E was reduced by 87% in August compared to the non-treated group C. In October, the difference in average abomasal worm counts between group E and C was insignificant. Due to weight loss at the end of the grazing season, the control group showed a significantly lower average weight increase.
有人尝试通过给放牧的犊牛喂食捕食线虫真菌——大孢隔指孢（DSM 6703）来控制奥斯特他线虫。一组犊牛（E组）在放牧季节的前两个月喂食真菌材料，另一组为未处理的对照组（C组）。E组在8月和9月的粪便虫卵计数显著较低。在7月和9月的四个时间点，真菌处理组地块上的牧草幼虫计数显著低于对照地块上记录的计数。E组8月份皱胃幼虫和成虫的平均虫数显著减少，与未处理的C组相比，E组8月份皱胃的平均总虫数减少了87%。10月份，E组和C组之间皱胃蠕虫平均数量的差异不显著。由于放牧季节结束时体重减轻，对照组的平均体重增加显著较低。
