The aim of study was to estimate the prevalence and intensity of intestinal parasite infections in pigs in Poland and evaluate the influence of factors related to the production system on the infection intensity.
A total of 70 pig farms of all Polish provinces, differing in the herd size and production system, were selected for the study. Fresh faecal samples were collected from all age groups: suckling piglets, weaners, fatteners, and lactating sows. Moreover, data were obtained regarding the size of the herd, the use of paddock and all-in/all-out system, the presence of diarrhoea, and the type of flooring.
Parasite eggs or oocysts were detected in 57 of the 70 examined pig farms. spp. eggs were found in the largest number of farms (68.6%). Moreover, coccidia (42.9%), (28.6%), (21.4%), and spp. (11.4%) were detected. The highest prevalence of coccidia and spp. was found in suckling piglets, and in fatteners, and spp. in sows. Higher prevalence of parasites was detected in small farms than in medium and large farms, except the prevalence of coccidia, which was the highest in medium farms. Simultaneous infection with several parasites was more often detected than with one parasite. Odds ratio of parasites occurrence was higher in farms with paddock and litter floor and in farms which do not use all-in/all-out system.
Relatively high prevalence of intestinal parasites was found in pigs in Poland. Moreover, specific distribution of parasites in different age groups and farms of different size was observed. Influence of breeding factors on parasite prevalence was identified.
本研究的目的是估计波兰猪肠道寄生虫感染的流行率和感染强度，并评估与生产系统相关的因素对感染强度的影响。
从波兰所有省份选取了70个猪场进行研究，这些猪场的畜群规模和生产系统各不相同。采集了所有年龄组的新鲜粪便样本：哺乳仔猪、断奶仔猪、育肥猪和哺乳母猪。此外，还获得了有关畜群规模、围场使用情况和全进全出系统、腹泻情况以及地板类型的数据。
在70个被检查的猪场中，有57个检测到寄生虫卵或卵囊。在最多的猪场（68.6%）中发现了 spp. 卵。此外，还检测到球虫（42.9%）、（28.6%）、（21.4%）和 spp.（11.4%）。球虫和 spp. 在哺乳仔猪中的流行率最高， 在育肥猪中最高, spp. 在母猪中最高。除球虫在中型猪场中流行率最高外，小型猪场中寄生虫的流行率高于中型和大型猪场。同时感染几种寄生虫的情况比感染一种寄生虫的情况更常见。在有围场和垫料地板的猪场以及不使用全进全出系统的猪场中，寄生虫出现的优势比更高。
在波兰的猪中发现肠道寄生虫的流行率相对较高。此外，还观察到寄生虫在不同年龄组和不同规模猪场中的特定分布。确定了养殖因素对寄生虫流行率的影响。
