Twelve small plots (2 x 2 m) progressively received parasitised faeces on two occasions between July 1980 and February 1983. They were sprinkled from March to October. Egg and larval populations dynamics in faeces and herbage were followed. Teladorsagia and Trichostrongylus could develop all through the year, at lower speed and rate during cold months. Haemonchus larvae were observed only from May to October. With irrigation, eggs developed into infective larvae in 2-4 weeks, peaks of larvae on grass occurred in weeks 4 to 5. The maximum number of L3/100 eggs was 11.3 for Teladorsagia, 6.99 for Trichostrongylus and 10.65 for Haemonchus, after July faeces deposit.
1980年7月至1983年2月期间，12个小地块（2×2米）分两次逐渐接受了被寄生虫感染的粪便。粪便在3月至10月间进行播撒。对粪便和牧草中的虫卵及幼虫种群动态进行了跟踪。细颈线虫和毛圆线虫全年均可发育，但在寒冷月份发育速度和速率较低。血矛线虫幼虫仅在5月至10月间被观察到。通过灌溉，虫卵在2至4周内发育成感染性幼虫，牧草上幼虫的高峰期出现在第4至5周。在7月粪便沉积后，每100个虫卵中，细颈线虫的L3幼虫最多数量为11.3，毛圆线虫为6.99，血矛线虫为10.65。
