OBJECTIVE To estimate costs associated with prevention and treatment of bovine respiratory disease (BRD) in preweaned calves on US beef cow-calf operations. DESIGN Cross-sectional survey. SAMPLE 43 beef cow-calf producers whose operations had a history of BRD in preweaned calves. PROCEDURES Mail and electronic surveys were developed and administered to producers in Nebraska, North Dakota, and South Dakota to obtain information regarding costs of BRD prevention and treatment. Descriptive statistics were generated. Mixed linear regression models were used to assess factors associated with the costs of vaccines, medicine, and labor and percentage time spent on prevention and treatment of BRD in cows, replacement heifers, and preweaned calves. RESULTS 7 mail and 36 electronic surveys were completed. Median annual costs for BRD vaccines were $2.25, $4.00, and $6.25/animal, and median annual labor costs for vaccination were $4.58, $3.00, and $5.00/animal for cows, heifers, and preweaned calves, respectively. Median annual costs for medicine and labor to treat preweaned calves for BRD were $11.00 and $15.00/ affected calf, respectively. Adjusted mean annual BRD vaccine cost for preweaned calves ($7.67/animal) was significantly greater than that for cows ($3.18/animal) and heifers ($4.48/animal). CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that labor costs associated with BRD vaccination and treatment were similar to or exceeded the cost of vaccines and medicine, and most of those labor costs were associated with gathering and sorting cattle. Therefore, costs associated with labor as well as medicine and vaccines should be considered during the development of BRD prevention and treatment plans.
目的 估算美国肉牛繁殖-育肥场断奶前犊牛患牛呼吸道疾病(BRD)的预防和治疗成本。 设计 横断面调查。 样本 43个肉牛繁殖-育肥场生产者,其养殖场的断奶前犊牛有BRD病史。 程序 制定了邮寄和电子调查问卷,并向内布拉斯加州、北达科他州和南达科他州的生产者发放,以获取有关BRD预防和治疗成本的信息。生成描述性统计数据。使用混合线性回归模型评估与疫苗、药品和劳动力成本以及母牛、后备小母牛和断奶前犊牛预防和治疗BRD所花费时间百分比相关的因素。 结果 完成了7份邮寄调查问卷和36份电子调查问卷。BRD疫苗的年成本中位数分别为每头母牛2.25美元、每头后备小母牛4.00美元和每头断奶前犊牛6.25美元,母牛、后备小母牛和断奶前犊牛接种疫苗的年劳动力成本中位数分别为每头4.58美元、3.00美元和5.00美元。治疗断奶前犊牛BRD的药品和劳动力年成本中位数分别为每头患病犊牛11.00美元和15.00美元。断奶前犊牛的调整后平均年BRD疫苗成本(每头动物7.67美元)显著高于母牛(每头动物3.18美元)和后备小母牛(每头动物4.48美元)。 结论及临床意义 结果表明,与BRD疫苗接种和治疗相关的劳动力成本与疫苗和药品成本相当或超过了后者,且大部分劳动力成本与聚集和挑选牛群有关。因此,在制定BRD预防和治疗计划时,应考虑劳动力以及药品和疫苗的成本。
