While working on farms with livestock increases the risk of injury among farm workers in comparison to other commodity farms, few studies have examined the role offarm management practices in association with the risk of cattle-related injury. We examined the farm management practices of Kentucky beef cattle farms in association with self-reported rates of cattle-related injuries among workers. We conducted a mail survey of a random sample of 2,500 members of the Kentucky Cattlemen's Association. Results from 1,149 farm operators who were currently raising beef cattle and provided complete survey response are reported. During the busy season, the principal operator worked 20 hours per week on the beef operation, and among all farm employees, the beef operation required 35 hours per week (median cumulative hours). There were 157 farms that reported a cattle-related injury in the past year among the principal operator or a family member, yielding an annual cattle-related injury rate of 13.7 beef cattle farms per 100 reporting at least one cattle-related injury. The majority of these injuries were associated with transporting cattle, using cattle-related equipment (head gates, chutes, etc.), and performing medical or herd health tasks on the animal. A multivariable logistic regression analysis of cattle-related injuries indicated that the risk of injury increased with increasing herd size, increasing hours devoted to the cattle operation per week by all workers, and the number of different medical tasks or treatments performed on cattle without the presence of a veterinarian. Farms that performed 9 to 13 tasks/treatments without a veterinarian had a two-fold increased risk of a cattle-related injury (OR = 1.98; 95% Cl: 1.08-3.62) in comparison to farms that performed 0 to 4 tasks without a veterinarian. In adjusted analyses, the use of an ATV or Gator for cattle herding was associated with a significantly reduced risk of cattle-related injury (OR = 0.51; 95% CI: 0.30-0.86) in comparison to other herding methods. This study indicates that a substantial proportion of cattle-related injuries are associated with work activities related to handling practices and cattle restraining equipment.
与其他商品农场相比,在有牲畜的农场工作会增加农场工人受伤的风险,但很少有研究探讨农场管理实践与牛相关伤害风险之间的关系。我们研究了肯塔基州肉牛农场的农场管理实践与工人自我报告的牛相关伤害发生率之间的关系。我们对肯塔基州养牛者协会的2500名成员进行了随机抽样邮件调查。报告了1149名目前饲养肉牛并提供完整调查回复的农场经营者的结果。在繁忙季节,主要经营者每周在肉牛养殖业务上工作20小时,在所有农场员工中,肉牛养殖业务每周需要35小时(中位数累计小时数)。在过去一年中,有157个农场报告主要经营者或家庭成员发生了与牛相关的伤害,每100个报告至少一起与牛相关伤害的肉牛农场的年牛相关伤害发生率为13.7。这些伤害大多数与运输牛、使用与牛相关的设备(头部闸门、斜槽等)以及对动物进行医疗或畜群健康任务有关。对与牛相关伤害的多变量逻辑回归分析表明,伤害风险随着畜群规模的增加、所有工人每周投入到肉牛养殖业务的时间增加以及在没有兽医在场的情况下对牛进行的不同医疗任务或治疗的数量增加而增加。与没有兽医在场时进行0至4项任务的农场相比,没有兽医在场时进行9至13项任务/治疗的农场发生与牛相关伤害的风险增加了两倍(OR = 1.98;95% CI:1.08 - 3.62)。在调整分析中,与其他放牧方法相比,使用全地形车(ATV)或多功能车(Gator)放牧与显著降低的与牛相关伤害风险相关(OR = 0.51;95% CI:0.30 - 0.86)。这项研究表明,相当一部分与牛相关的伤害与处理操作和牛约束设备相关的工作活动有关。
