Endoparasitosis is a critical health challenge in the management of Creole goats under extensive production systems due to its negative impact on animal health and productivity. This study determined the occurrence of endoparasites and identified associated risk factors in Creole goats from the southern coast of Peru. Fecal samples were collected from 129 goats in two localities of the Pisco province to detect the presence of oocysts from spp. and eggs from trichostrongyles, spp., spp., and . Data were analyzed using logistic regression models and adjusted through bootstrapping and stepwise selection methods, with locality, feeding type, age, and body condition as predictive variables. The results revealed a high occurrence of spp. (86.0%) and trichostrongyles (65.1%), while (14.0%) and spp. (7.0%) were exclusively identified in Independencia and San Clemente, respectively. Mixed infestations were predominant (65.9%), occurring more frequently in Independencia (75.9%) than in San Clemente (57.7%) (OR: 2.26, < 0.05). The likelihood of infestation was significantly higher in Independencia for spp. (OR: 5.72, < 0.01) and (OR: 61.4, < 0.01). Moreover, goats fed exclusively on alfalfa were more likely to be infested with compared to those fed a mixed diet of alfalfa and crop residues (OR: 0.06, < 0.05). These findings underscore the necessity of implementing comprehensive health programs tailored to local management and feeding conditions.
由于内寄生虫病对动物健康和生产力有负面影响，在粗放养殖系统下管理克里奥尔山羊时，它是一个关键的健康挑战。本研究确定了秘鲁南部海岸克里奥尔山羊体内内寄生虫的发生情况，并识别了相关风险因素。从皮斯科省两个地区的129只山羊采集粪便样本，以检测艾美耳属球虫卵囊以及毛圆科线虫、马歇尔线虫属、奥斯特线虫属和细颈线虫属虫卵的存在。使用逻辑回归模型分析数据，并通过自抽样法和逐步选择法进行调整，将地区、饲养类型、年龄和身体状况作为预测变量。结果显示，艾美耳属球虫的感染率很高（86.0%），毛圆科线虫的感染率为65.1%，而分别仅在因德彭登西亚和圣克莱门特地区检测到等孢球虫（14.0%）和马歇尔线虫属（7.0%）。混合感染占主导（65.9%），在因德彭登西亚地区（75.9%）比在圣克莱门特地区（57.7%）更频繁发生（比值比：2.26，P<0.05）。在因德彭登西亚地区，艾美耳属球虫（比值比：5.72，P<0.01）和等孢球虫（比值比：61.4，P<0.01）的感染可能性显著更高。此外，与喂食苜蓿和作物残渣混合饲料的山羊相比，仅以苜蓿为食的山羊感染艾美耳属球虫的可能性更小（比值比：0.06，P<0.05）。这些发现强调了实施针对当地管理和饲养条件的综合健康计划的必要性。
