This study aimed to evaluate and quantify the different factors affecting the costs of mastitis in cattle, to quantify the annual and monthly financial losses attributed to mastitis, and to estimate production losses using average linear scores found on The Dairy Herd Improvement Association somatic cell count (SCC) sheets and bulk tank SCC per lactation number.
All data (bovine mastitis-associated costs and expenditures in Egyptian dairy herds) were analyzed using SPSS/PCT, 2001. A partial budget technique using spreadsheet software and the general linear model procedure was used to analyze the productive and financial measures.
Mastitis was present in 57.1% of cows (240/420), while clinical mastitis (CM) was present in 19% of them (80/420). The geometric mean of SCC/ml in bulk tank milk samples of 150 cattle dairy farms was 556.3×10. The annual subclinical mastitis (SCM)-related economic loss was 21,933,258.6 LE, and the two most important cost components were the subsequent decrease in milk production and quality premium losses (93% and 7% of SCM costs, respectively). The quality premium loss was 1,369,602.1 LE. On the other hand, the annual economic loss due to decreased milk production as a result of SCM was 20,563,656.5 LE. The total cost of 80 CM cases, including the failure and preventive costs, was 1,196,871.4 LE, including 1,169,150.4 LE failure costs (106,336.0 LE in direct costs and 1,062,814.4 LE in indirect costs) and 27,721.0 LE preventive costs. The average cost per CM case was 28,760.9 LE, including veterinary time and consultation fees of 250.0 LE (1%), labor 562.5 LE (2%), premature culling 736,000.0 LE (77%), decreased milk production 4085.18 LE (13.7%), discarded milk 185.3 LE (1%), and drugs and treatments 328.9 LE (1%). The total costs of CM (expenditures) extra control and preventive measures, including the diagnosis of CM for 80 cows annually in 20 Egyptian dairy farms were 27,721.0 LE, representing 346.5 LE or 1% of the total cost of CM cases. The cost of monitoring and diagnostic measures was 8635.2 LE, representing 107.9 LE or 1% of the total cost of a case of CM.
The method used for cost estimation, in this study, is highly adaptable to individual cattle farms and had a major role in assessing specific control and management measures. The concepts described in this paper help to improve our understanding of the full economic impact of clinical and subclinical mastitis in cattle in Egypt. Assessing the economic losses from mastitis to determine the economic costs and losses occurring in Egyptian dairy farms is critical for encouraging farmers to acknowledge the scale of the problem and implement effective management practices aimed at improving mastitis control and reducing the associated costs.
本研究旨在评估和量化影响奶牛乳腺炎成本的不同因素,量化归因于乳腺炎的年度和月度经济损失,并使用奶牛改良协会体细胞计数(SCC)表上的平均线性评分和每个泌乳期的奶罐SCC来估计生产损失。
使用SPSS/PCT 2001对所有数据(埃及奶牛场与牛乳腺炎相关的成本和支出)进行分析。采用电子表格软件和一般线性模型程序的部分预算技术来分析生产和财务指标。
420头奶牛中有57.1%(240/420)患有乳腺炎,其中19%(80/420)患有临床乳腺炎(CM)。150个奶牛场的奶罐奶样中每毫升SCC的几何平均值为556.3×10。与亚临床乳腺炎(SCM)相关的年度经济损失为21,933,258.6埃及镑,两个最重要的成本组成部分是随后牛奶产量的下降和质量溢价损失(分别占SCM成本的93%和7%)。质量溢价损失为1,369,602.1埃及镑。另一方面,由于SCM导致牛奶产量下降的年度经济损失为20,563,656.5埃及镑。80例CM病例的总成本,包括失败成本和预防成本,为1,196,871.4埃及镑,其中失败成本为1,169,150.4埃及镑(直接成本为106,336.0埃及镑,间接成本为1,062,814.4埃及镑),预防成本为27,721.0埃及镑。每例CM病例的平均成本为28,760.9埃及镑,包括兽医时间和咨询费250.0埃及镑(1%)、劳动力562.5埃及镑(2%)、过早淘汰736,000.0埃及镑(77%)、牛奶产量下降4085.18埃及镑(13.7%)、废弃牛奶185.3埃及镑(1%)以及药品和治疗费用328.9埃及镑(1%)。CM(支出)额外控制和预防措施的总成本,包括每年在20个埃及奶牛场对80头奶牛进行CM诊断的费用为27,721.0埃及镑,占CM病例总成本的346.5埃及镑或1%。监测和诊断措施的成本为8635.2埃及镑,占一例CM病例总成本的107.9埃及镑或1%。
本研究中使用的成本估算方法高度适用于各个奶牛场,并且在评估特定的控制和管理措施方面发挥了重要作用。本文所述的概念有助于提高我们对埃及奶牛临床和亚临床乳腺炎全面经济影响的理解。评估乳腺炎造成的经济损失以确定埃及奶牛场发生的经济成本和损失对于鼓励农民认识到问题的严重性并实施旨在改善乳腺炎控制和降低相关成本的有效管理措施至关重要。
