This study investigated the epidemiology of gastrointestinal (GI) parasite infections among 42 meat goat herds in Khon Kaen, Northeast Thailand, based on 913 fecal samples. The predominant parasites identified in the herd were strongyle (100.0%, 42/42), spp. (73.8%, 31/42), spp. (66.7%, 28/42), spp. (64.3%, 27/42), spp. (38.1%, 16/42), and spp. (7.1%, 3/42). Coinfection with at least two GI parasites was observed in 90.4% of the herds. Molecular analysis confirmed and spp. as the strongyle species. The study explored parasite prevalence among animals, finding significant correlations with season, sex, age, and breed. Notably, the wet season showed increased strongyle and spp. infections. Female animals had higher odds of strongyle infection, while younger animals (less than 1 year) were more susceptible. Conversely, animals aged over 1 year were more likely to be positive for spp., spp., and spp. infections. Female animals exhibited poor body condition scores (BCS) and anemia, as indicated by the FAMACHA score and packed cell volume (PCV) levels. Correlations between age, clinical signs, hematological parameters, biochemistry, and GI parasite burdens were investigated, revealing significant associations. These findings emphasize the need for tailored intervention strategies considering seasonal variations, age, and sex differences for effective GI parasite control in meat goats. Prioritizing animals exhibiting poor BCS and elevated FAMACHA score is imperative to mitigate the deleterious impacts of GI parasitic infections on health and productivity.
本研究基于913份粪便样本,对泰国东北部孔敬府的42个肉用山羊群的胃肠道(GI)寄生虫感染流行病学进行了调查。在这些羊群中鉴定出的主要寄生虫为圆线虫(100.0%,42/42)、 属(73.8%,31/42)、 属(66.7%,28/42)、 属(64.3%,27/42)、 属(38.1%,16/42)和 属(7.1%,3/42)。在90.4%的羊群中观察到至少两种GI寄生虫的混合感染。分子分析证实 属和 属为圆线虫种类。该研究探讨了动物体内寄生虫的流行情况,发现与季节、性别、年龄和品种存在显著相关性。值得注意的是,雨季圆线虫和 属感染增加。雌性动物感染圆线虫的几率更高,而年幼动物(小于1岁)更易感染。相反,1岁以上的动物 属、 属和 属感染呈阳性的可能性更大。如FAMACHA评分和红细胞压积(PCV)水平所示,雌性动物的体况评分(BCS)较差且存在贫血现象。研究了年龄、临床症状、血液学参数、生物化学与GI寄生虫负荷之间的相关性,发现存在显著关联。这些发现强调,需要考虑季节变化、年龄和性别差异制定针对性的干预策略,以有效控制肉用山羊的GI寄生虫。优先处理BCS较差和FAMACHA评分升高的动物,对于减轻GI寄生虫感染对健康和生产力的有害影响至关重要。
