摘要

本研究旨在调查尼日利亚贡贝州小型反刍动物中难消化异物嵌塞的患病率和类型。采样于2019年2月至2020年1月期间进行,采用系统随机采样技术,在贡贝州主要屠宰场屠宰前对选定的山羊和绵羊进行尸检。观察并记录每只动物的性别、年龄和身体状况评分。对瘤胃和网进行尸检,并从腹腔中取出回收的异物,进行鉴定和记录。在检查的1730只小反刍动物中,1167只(67.46%)的瘤胃和网中含有各种难以消化的异物。山羊(38.0%)的患病率显著高于绵羊(23.7%)(χ2=58.047,p<0.0001)。贡贝、亚马尔图-德巴、阿克科、富纳卡耶和夸米LGA的患病率分别为13.6%、12.9%、12.1%、11.8%和11.4%。成人(59.6%)与青年(2.1%)相比,难消化异物的发生率显著(p<0.0001;χ2=732.87;OR=47.009),女性(42.5%)与男性(19.2%)相比,身体状况评分较差的山羊(χ2=177.03,p<0.01)和绵羊(χ2=191.39,p<0.01)与中等和良好身体状况的山羊相比更高。与受影响的山羊和绵羊的网相比,受影响的绵羊瘤胃中回收的难消化异物比例显著更高。塑料是山羊和绵羊最常见的难以消化的异物,其次是种子/坚果、绳子和布。缺乏足够的塑料垃圾处理系统、广泛的管理系统和城市地区牲畜的自由放牧是研究地区反刍动物中难消化异物高流行的易感因素之一。因此,建议要求政府机构和畜牧养殖户参与合作干预计划,以提高公众对如何正确处理生活垃圾的认识。

Indigestible Foreign Materials Impaction of Small Ruminants In Gombe State, Nigeria
This study aimed to investigate the prevalence and type of indigestible foreign material impaction in small ruminants in Gombe State, Nigeria. Sampling was carried out between February 2019 and January 2020, systematic random sampling technique, ante-mortem examination of selected goats and sheep prior to slaughter at the major abattoirs in Gombe State. The sex, age and body condition score of each animal was observed and recorded accordingly. Post-mortem examination of the rumen and reticulum was performed and foreign materials recovered were removed from the abdominal cavity, identified and recorded. Out of 1730 small ruminants examined, 1167 (67.46%) were found to harbour various types of indigestible foreign materials in their rumen and reticulum. The prevalence was significantly (χ2 = 58.047, p < 0.0001) higher in goats (38.0%) compared to sheep (23.7%). Prevalence rates in respective LGA sampled from Gombe, Yamaltu Deba, Akko, Funakaye and Kwami LGAs was 13.6%, 12.9%, 12.1%, 11.8% and 11.4% respectively. The prevalence of indigestible foreign materials was found to be significantly (p< 0.0001; χ2 = 732.87; OR = 47.009) higher in adult (59.6%) compared to young (2.1%), significantly (p< 0.0001; χ2 = 637.61; OR = 31.145) higher in female (42.5%) compared to male (19.2%), higher in goats (χ2 = 177.03, p < 0.0001) and sheep (χ2 = 191.39, p < 0.0001) with poor body condition score compared to those with medium and good body condition Significantly higher proportions of indigestible foreign materials were recovered in the rumen of affected goats and sheep compared to their reticulum. Plastic was the most commonly encountered indigestible foreign materials in goats and in sheep, followed by seed/nuts, rope and cloth. Lack of adequate plastic waste disposal system, extensive management system and free grazing of livestock in urban area are among the predisposing factors to the high prevalence of indigestible foreign material in ruminants in the study area. It was therefore recommended that collaborative intervention schemes involving government’s agencies and livestock farmers are required to increase public awareness about how to properly dispose of domestic waste.
