Parasite infections, unlike regulated animal diseases, do not often receive attention. In fact, parasites are major sources of financial losses in pig enterprises, particularly in subsistence and small-scale pig production systems.
To identify and quantify the prevalence of ecto- and endo-parasites among peri-urban free-roaming pigs (FRP) in Gert Sibande District Municipality (GSDM), Mpumalanga.
Pig owners were identified using the snowball sampling method since no sampling frame for FRP farmers exists. Stratified sampling was used to select pigs for sampling for ecto- and endo-parasites. A form was used to record the observations. Pairwise correlation analysis was performed using Stata 15.0. The SPSS V28.0 statistical package was used to perform the chi-square test (X) to assess the distribution of parasites in different age groups. The prevalence of parasites was assessed in different age groups of pigs using multi-response crosstabs. Multivariate analysis of variance (MANOVA) was used to estimate the marginal mean of parasites according to municipality. Statistical significance was assessed at α ≤ 0.05.
Over 90% (91.2%) of the pigs examined were infested with at least one parasite, including , , , , , , spp, , and spp. The correlation between Ascaris suum and body condition was weak but statistically significant (r = 0.24; < 0.05).
Policy makers, animal researchers and veterinary services must focus on developing policies, risk communication and community engagement materials, which target pig farmers in peri-urban areas such as Gert Sibande District Municipality, Mpumalanga Province.
与受管控的动物疾病不同，寄生虫感染往往未受到关注。事实上，寄生虫是养猪企业经济损失的主要来源，尤其是在自给自足和小规模养猪生产系统中。
确定并量化姆普马兰加省格特·西班德区市（GSDM）城郊自由放养的猪（FRP）体内外寄生虫的感染率。
由于不存在FRP养殖户的抽样框架，采用滚雪球抽样法确定猪主。采用分层抽样法选择猪进行体内外寄生虫抽样。使用表格记录观察结果。使用Stata 15.0进行成对相关分析。使用SPSS V28.0统计软件包进行卡方检验（X），以评估不同年龄组寄生虫的分布情况。使用多响应交叉表评估不同年龄组猪的寄生虫感染率。使用多变量方差分析（MANOVA）根据市来估计寄生虫的边际均值。在α≤0.05水平评估统计学显著性。
超过90%（91.2%）的受检猪感染了至少一种寄生虫，包括猪蛔虫、猪鞭虫、猪结节虫、猪冠尾线虫、猪食道口线虫、有齿冠尾线虫、类圆线虫属、猪疥螨和猪虱。猪蛔虫与身体状况之间的相关性较弱，但具有统计学显著性（r = 0.24；P<0.05）。
政策制定者、动物研究人员和兽医服务部门必须专注于制定政策、风险沟通材料和社区参与材料，目标受众为姆普马兰加省格特·西班德区市等城郊地区的养猪户。
