The levels of nematode egg production in goats and the availability of infective larvae (L3) on pasture were investigated on a dairy unit in New South Wales, Australia. The output of eggs by adult goats was always above 300 epg. The profile of the graph of larval availability in herbage paralleled those for temperature and rainfall, suggesting that larval peaks occurred when the temperature and availability of moisture were optimal. The dominant genus was Trichostrongylus, followed by Haemonchus, then Ostertagia. A larger proportion of Haemonchus larvae in the cultures of faeces were collected during the summer months.
在澳大利亚新南威尔士州的一个奶牛场，对山羊体内线虫产蛋水平以及牧场上感染性幼虫（L3）的可获得性进行了调查。成年山羊的产蛋量始终高于300个虫卵/克。牧草中幼虫可获得性的图表曲线与温度和降雨量的曲线相似，这表明当温度和湿度条件适宜时，幼虫数量会出现峰值。优势属为毛圆线虫属，其次是血矛线虫属，然后是奥斯特他线虫属。在夏季月份收集的粪便培养物中，血矛线虫属幼虫的比例更大。
