损失和狗袭击(DAs)对牲畜的经济影响往往被忽视,包括产量下降等因素,治疗和处理费用,以及受伤动物的死亡。这项研究评估了流行病学,治疗性的,以及使用转介给兽医教学医院的农场动物记录进行的11年调查中对牲畜的DA的病理学发现。被狗袭击的牲畜包括31只羊,11匹马,3头牛,3只山羊,两头猪共50只动物。被狗咬伤的解剖部位被确定为头部/颈部,胸/骨盆四肢,腹部/侧腹,臀部/尾巴,和多个受影响的区域(两个或多个咬伤部位)。此外,伤害的严重程度分为四个等级,与儿童狗咬伤的分类不同。大多数牲畜受到一级伤害(26%)和二级伤害(28%),而在46%的DA中观察到3级和4级损伤。此外,35只动物(70%)出院,9人(18%)死亡,和6(12%)人道安乐死。DA可能是将牲畜物种转诊到临床护理的重要原因,重伤,和相当数量的死亡。在这项研究中,我们首次在巴西中西部提供有关牲畜DA的信息。
Losses and the economic impact of dog attacks (DAs) on livestock are often overlooked and include factors such as decreased production, expenses for treatment and handling, and death of injured animals. This study evaluated the epidemiological, therapeutic, and pathological findings of DAs on livestock over an 11-year survey using the records of farm animals referred to a Veterinary Teaching Hospital. Livestock attacked by dogs included 31 sheep, 11 horses, 3 cattle, 3 goats, and 2 pigs, totaling 50 animals. Anatomical locations injured by dog bites were identified as head/neck, thoracic/pelvic limbs, abdomen/flank, rump/tail, and multiple affected regions (two or more bite sites). Additionally, the severity of the injuries was classified into four degrees adapted from the classification of dog bite injuries in children. Most livestock presented Grade 1 (26%) and Grade 2 (28%) injuries, while Grade 3 and Grade 4 injuries were observed in 46% of DAs. Furthermore, 35 animals (70%) were discharged, 9 (18%) died, and 6 (12%) were humanely euthanized. DAs may represent a significant cause for referring livestock species to clinical care, severe injuries, and a considerable number of deaths. In this study, we provide information regarding DAs on livestock for the first time in Midwestern Brazil.
