The prevalence of swine gastrointestinal parasites was determined from all listed large swine operations (28) and a geographically representative sample (70) of the population of small hog farm operations in Oklahoma. Fecal samples (n = 975) were collected from 98 farms. From the 98 farms, parasites were recovered in pig feces as follows: Ascaris, 53.0%, strongyles, 53.1%, Trichuris, 35.7%, spirurids, 6.1%, Strongyloides, 19.4%, coccidia, 57.1%, and Balantidium, 55.1%. A higher percentage (16.5%) of hogs maintained on cement floors were positive for Ascaris than were those on either dirt lots (11.9%) or slatted floors (9.9%), but pigs on dirt lots were more often positive with a higher percentage of coccidia (21.0%) than those on either cement or slatted floors (8.5% and 6.0%, respectively). Prevalence of Trichuris was essentially the same (6.8% to 11.3%) in hogs from all 3 management practices.
从俄克拉何马州所有列出的大型养猪场（28个）以及该州小型养猪场中具有地理代表性的样本（70个）中，确定了猪胃肠道寄生虫的流行情况。从98个农场收集了粪便样本（n = 975）。在这98个农场的猪粪便中检出的寄生虫如下：蛔虫，53.0%；圆线虫，53.1%；鞭虫，35.7%；旋尾线虫，6.1%；类圆线虫，19.4%；球虫，57.1%；结肠小袋纤毛虫，55.1%。在水泥地面饲养的猪中，蛔虫阳性率（16.5%）高于在土场（11.9%）或板条地面（9.9%）饲养的猪，但土场饲养的猪球虫阳性率更高（21.0%），高于水泥地面（8.5%）和板条地面（6.0%）饲养的猪。在所有三种管理方式饲养的猪中，鞭虫的流行率基本相同（6.8%至11.3%）。
