Equipment-related wounds and associated risk factors in working equids of the Oromia national regional state in Ethiopia

Abstract

Working equids support the livelihoods of millions of low-income households worldwide and face several welfare challenges. Although equipment-related wounds are common, little is known about specific risk factors. This cross-sectional study surveyed equids used for cart-work in three Ethiopian towns. Number, size, severity and location of wounds were recorded for each animal, as well as work equipment characteristics and indicators of equipment fit and assembly. Questionnaires were conducted with each cart-driver focusing on equipment practices and attitudes. Logistic regression models were generated to investigate associations between equipment-related wounds (outcome) and equipment, work, driver and animal-related factors (predictors). In total, 369 equids and cart-drivers were surveyed. The prevalence of equipment-related wounds was 72.6% (268/369) with girth wounds being the predominant wound type in horses (50%; 122/244) while donkeys had predominantly shaft-related wounds (59%; 72/122). Donkeys were two times more likely to have equipment-related wounds than horses. The presence of equipment-related wounds was associated with factors such as previously having wounds, inadequate collar positioning and using purchased equipment compared to partly home-made equipment. Characteristics of specific equipment components were also associated with certain wound types, such as narrow saddle pressure points and saddle wounds. Equipment-related wounds are highly prevalent in working equids, representing a serious welfare concern. Factors relating to equipment design, fit and assembly were associated with the presence of wounds. Importantly, species differences require tailoring of preventive approaches amongst working equids. A better understanding of work equipment should therefore be promoted as part of wound prevention and animal welfare strategies.
