The aim of this study was to find the direct economic losses due to the three viral causes of the avian respiratory syndrome, including Newcastle disease (ND), H9N2 influenza, and infectious bronchitis (IB) in stamped-out broiler farms during 2016-2017 across the country. This study was carried out on the information on cross-sectional monitoring in the years 2016-2017. The statistical society of the study was all the active broiler farms of the country stamped out due to respiratory syndrome. This study used compensation insurance data, and other sources. One-way ANOVA or Kruskal-Wallis tests were used to analyze normally and non-normally distributed data. In total, during the study period, 132 broiler farms and 1,723,131 fowls were stamped out. According to the results of the present investigation, the sum of costs and losses due to respiratory complex was 9.47 $US Million, 2016-2017 (5.72 from $US Million chicken meat losses and 3.75 $US Million was the total cost). ND was the main cause of economic losses and costs with 3.86 $US equal to 40.8% of the total. Cost of feeding was the highest followed by veterinary services and medicines, vaccination, and 1-day-old chicks costs with 2.27, 1.11, 0.33, and 0.036 $US Million, 2016-2017. In conclusion, we need to improve the preventive measures against respiratory viruses, especially NDV. Additionally, as the cost of feeding was the largest, it is important to shorten the time interval between disease occurrence and stamping out to reduce the cost.
本研究旨在确定导致禽呼吸道综合征的三种病毒（包括新城疫（ND）、H9N2 流感和传染性支气管炎（IB））在 2016-2017 年期间，在全国范围内扑杀的肉鸡养殖场造成的直接经济损失。本研究基于 2016-2017 年的横断面监测信息进行。研究的统计总体为因呼吸道综合征而扑杀的全国所有活跃肉鸡养殖场。本研究使用了赔偿保险数据和其他来源。采用单向方差分析或 Kruskal-Wallis 检验对正态和非正态分布数据进行分析。在研究期间，共有 132 个肉鸡养殖场和 1723131 只鸡被扑杀。根据本研究的结果，呼吸道综合征导致的成本和损失总计为 947 万美元，2016-2017 年（572 万美元来自鸡肉损失，375 万美元是总成本）。ND 是造成经济损失和成本的主要原因，占总数的 40.8%，相当于 3.86 亿美元。饲料成本最高，其次是兽医服务和药品、疫苗和 1 日龄雏鸡成本，分别为 2.27、1.11、0.33 和 0.036 亿美元，2016-2017 年。总之，我们需要改进针对呼吸道病毒的预防措施，特别是 NDV。此外，由于饲料成本最高，缩短疾病发生和扑杀之间的时间间隔以降低成本非常重要。
