Between September 1982 and March 1984, 101 Western Australian piggeries with 15 or more sows were surveyed to determine the prevalence of internal parasites and examine the relationship between parasitism and management practices. Faecal samples were collected from 20 pigs in 4 age groups in randomly selected piggeries, and examined for the presence of eggs of helminth parasites and protozoan cysts. Evidence of nematode parasites was found in 79% of piggeries. Sows were more commonly affected than other classes of pigs with worm eggs being found in 68% of herds. Oesophagostomum spp was the most prevalent worm species, being found in pigs from 65% of piggeries and in sows in 60% of herds. Ascaris suum was the most common species of worm found in growing pigs. There was no evidence of infection with either Metastrongylus spp or Strongyloides spp in any of the herds sampled. Oocysts of coccidia were found in pigs from 56% of piggeries and Balantidium coli cysts were detected in pigs from 42% of piggeries sampled.
1982年9月至1984年3月期间，对西澳大利亚州101家存栏15头及以上母猪的养猪场进行了调查，以确定体内寄生虫的流行情况，并研究寄生虫感染与管理措施之间的关系。从随机挑选的养猪场中4个年龄组的20头猪采集粪便样本，检查是否存在蠕虫寄生虫卵和原生动物囊肿。在79%的养猪场中发现了线虫寄生虫感染迹象。母猪比其他猪群更容易受到感染，68%的猪群中发现了虫卵。结节虫属是最常见的蠕虫种类，在65%的养猪场的猪中以及60%的猪群的母猪中被发现。猪蛔虫是生长猪中最常见的蠕虫种类。在所采样的任何猪群中均未发现后圆线虫属或类圆线虫属感染的证据。在56%的养猪场的猪中发现了球虫的卵囊，在42%的采样养猪场的猪中检测到了结肠小袋纤毛虫囊肿。
