Financial losses related to placental retention in dairy herds in Turkey

ABSTRACT This study aimed to calculate the financial losses related to placental retention (PR) in dairy cattle in Turkey taking into consideration the previous study results in three different geographical regions and 87 herds of Turkey. The mean prevalence of PR in dairy herds was assumed to be 5.6% (4.1-6.7%). Direct (milk losses, treatment, and involuntary culling) and indirect losses (extended calving interval and extra insemination) were calculated. In the financial analysis, direct and indirect losses were calculated according to the current prices of 2022. As a result, the financial losses per infected dairy cattle were estimated at $ 249.7 (624 Lt milk eq.). A total of 67.7% ($173) of these resulted from direct losses, and the remainder 32.3% ($82.5), were indirect losses. PR was responsible for a total of $92 million (ranged from $67-110 million) losses, which equates to 1.2% (0.8-1.14%) of the annual milk production in Turkey. In conclusion, magnitude of PR-related losses will provide evidence-based decision support to the farmers and policymakers when determining the priorities for disease mitigation and control strategies.

摘要 本研究旨在结合土耳其3个不同地理区域及87个牛群的既往研究结果，测算土耳其奶牛胎衣不下（placental retention, PR）相关的经济损失。研究假设奶牛群中PR的平均患病率为5.6%（4.1%~6.7%）。本研究对直接损失（产奶损失、治疗费用及被动淘汰损失）与间接损失（产犊间隔延长及额外输精带来的损失）进行了测算。在财务分析环节，直接与间接损失均按照2022年现行价格计算。结果显示，每头感染PR的奶牛对应的经济损失约为249.7美元（折合624升牛奶当量）。其中67.7%（173美元）源自直接损失，剩余32.3%（82.5美元）为间接损失。PR共计造成约9200万美元的经济损失（波动范围为6700万~1.1亿美元），相当于土耳其年度牛奶总产量的1.2%（0.8%~1.14%）。综上，PR相关经济损失的量化结果可为养殖户与政策制定者在确定疾病防控优先级及防控策略时提供循证决策支持。
