2017年12月至2018年4月，通过使用结构化问卷采访农场主，开展了一项调查，以评估埃塞俄比亚比绍图镇44家商业养鸡场的生物安全状况。所得数据采用频率表汇总，使用Stata 14统计软件进行Pearson卡方检验和Fischer精确值分析。在被调查的养鸡场中，31家（70.45%）位于距离主要道路0 ~ 50 m范围内，39家（88.64%）位于距离最近的养鸡场500 m范围内，27家（61.36%）位于距离居民区0 ~ 20 m范围内。41家（93.18%）受访者披露其员工未接受过生物安全培训。被调查的鸡场中，30家（68.18%）设置围栏，40家（90.91%）在鸡场门口设置足浴，31家（70.45%）禁止游客进入，39家（88.64%）未与其他鸡场交换设备。此外，26个（59.09%）养殖场容易被野生鸟类进入，42个（95.45%）养殖场购买日龄雏鸡和饲料，40个（90.91%）养殖场与其他养殖场共用卡车。在被调查的养殖场中，仅有2家（4.55%）设置了限制人员进入的标志，9家（20.45%）设置了病鸡隔离室，14家（31.82%）妥善处理了死禽，10家（22.73%）保留了各种记录。职业（Fischer精确值= 8.40，P=0.019）、先前培训（Fischer精确值= 4.40，P=0.044）、场所来源（χ2 = 5.50， P=0.019）、养殖场容量（Fischer精确值= 13.50，P=0.002）与养殖场生物安全状况有统计学显著相关。调查发现，由公务员经营、雇员受过培训、拥有房地和大中型农场的农场生物安全状况良好。总之，养鸡场较差的生物安全状况要求在每个养鸡场实施良好的生物安全规范，并向养鸡场所有者及其雇员提供培训。
A survey was undertaken from December 2017 to April 2018 to assess the biosecurity status of 44 commercial chicken farms established in Bishoftu town, Ethiopia, by interviewing farm owners using a structured questionnaire. The obtained data were summarized using frequency tables and analyzed with Pearson's chi-square test and Fischer's exact value using Stata 14 statistical software. From the assessed chicken farms, 31 (70.45%) were located within 0–50 m from the main road, 39 (88.64%) situated 500 m from the nearest farms, and 27 (61.36%) placed within 0–20 m from the residential areas. Forty-one (93.18%) participants disclosed that their employees did not receive training on biosecurity. From the assessed chicken farms, 30 (68.18%) had fences, 40 (90.91%) had footbaths at their gates, 31 (70.45%) prohibited visitors entrance, and 39 (88.64%) did not exchange equipment with other farms. In addition, 26 (59.09%) farms were easily accessed by wild birds, each of 42 (95.45%) farms purchased day-old chicks and feed, and 40 (90.91%) shared trucks with other farms as well. Among the assessed farms, only 2 (4.55%) had signages to restrict people's access, 9 (20.45%) had isolation rooms for diseased chickens, 14 (31.82%) disposed of dead birds properly, and 10 (22.73%) kept various types of records. Occupation (Fischer's exact value = 8.40; P=0.019), previous training (Fischer's exact value = 4.40; P=0.044), source of the premises (χ2 = 5.50; P=0.019), and farm capacity (Fischer's exact value = 13.50; P=0.002) were found statistically significantly associated with the farm biosecurity status. The farm biosecurity status was found to be good in farms that were run by civil servants, had trained employees, are owned premises, and were of large and medium scales. In conclusion, the higher poor biosecurity status on chicken farms calls for the implementation of good biosecurity practices in each farm as well as the provision of training to the farm owners and their employees.
