Gastrointestinal nematode (GIN) infections of sheep and their interaction with selected morbidity parameters were studied in smallholder farms. 120 faecal samples were collected and examined using faecal flotation to determine nematode infection in sheep. Thus, the study demonstrated overall prevalence of 57.5% GIN infections, while the mean faecal egg count (FEC) was 517.5 EPG. The severity of GIN infection was determined based on EPG as a mild infection (EPG <500), 55.1%, moderate infection (EPG = 500-1500), 30.4%, and heavy infection (EPG >1500), 14.6%. Five genera of nematodes were identified using coproculture: (33.3%), (26.7%), (20%), (13.3%), and (6.7%). A significant difference was observed in the mean FEC among the FC ( < 0.001), FAMACHA© score ( < 0.01), and the BCS of the animals ( < 0.001). FEC was positively correlated with the FAMACHA© score (FS), while FC and BCS were negatively correlated. Thus, FAMACHA
本研究旨在探讨绵羊胃肠道线虫（GIN）感染及其与选定发病率参数之间的相互关系。在小农户农场中收集了 120 份粪便样本，并使用粪便漂浮法进行检查，以确定绵羊的线虫感染情况。研究结果显示，GIN 感染的总体流行率为 57.5%，平均粪便卵囊计数（FEC）为 517.5 个卵囊/克粪便。根据 EPG 确定 GIN 感染的严重程度：轻度感染（EPG<500）占 55.1%，中度感染（EPG=500-1500）占 30.4%，重度感染（EPG>1500）占 14.6%。使用粪便培养法鉴定出五种线虫属： （33.3%）、 （26.7%）、 （20%）、 （13.3%）和 （6.7%）。FC（ < 0.001）、FAMACHA©评分（ < 0.01）和动物 BCS 之间的平均 FEC 存在显著差异（ < 0.001）。FEC 与 FAMACHA©评分（FS）呈正相关，而 FC 和 BCS 呈负相关。因此，FAMACHA
