Two groups of six lambs were fed with grass cut from two plots which had been contaminated by spreading Trichostrongylus colubriformis larvae. One plot received larvae in December, the other in April. The post mortem examination results showed that the infectivity of overwintering larvae was significantly higher than that of fresh larvae. An inverse relationship was demonstrated between infectivity of larvae and egg production of adult worms developed from these larvae. The results are compared with those obtained under laboratory conditions.
两组各六只羔羊被喂食从两块已通过散播蛇形毛圆线虫幼虫而受到污染的地块割来的草。一块地在12月接收幼虫，另一块在4月。尸检结果表明，越冬幼虫的感染力明显高于新鲜幼虫。幼虫的感染力与由这些幼虫发育而成的成虫的产卵量之间呈反比关系。将这些结果与在实验室条件下获得的结果进行了比较。
