World Organization for Animal Health (OIE) recommends member countries to comply with global standards of animal welfare. The present study was conducted to reveal the compliance of animal welfare standards in slaughterhouses in Tehran province (Iran). The following three major parameters were evaluated through direct observation, study of plant records, and interviewing slaughterhouse staff across all 14 operative animal slaughterhouses in Tehran province: (1) employing trained and committed workers; (2) appropriate environment and proper design parameter; and (3) proper construction, equipment, and tools. Only 30% of modern slaughterhouses employed trained personnel for handling livestock in an appropriate way, which reaches zero for traditional slaughterhouses. Regarding electrical stunning application for sheep, animal welfare quality was significantly greater in modern slaughterhouses than in the traditional ones (P < 0.05). Out of nine slaughterhouses with unloading platforms and animal lairage, 55% and 35.7% were found to comply with standards, respectively. Concerning lairage parameters and entrance hall, modern plants stood higher compared to traditional slaughterhouses (P > 0.05). It is recommended training courses for involved veterinarians and slaughterhouse staff along with upgrading slaughterhouse construction.

世界动物卫生组织（OIE）建议成员国遵守全球动物福利标准。进行本研究以揭示在德黑兰省（伊朗）的屠宰场中动物福利标准的遵守情况。通过直接观察，工厂记录研究以及与德黑兰省所有14家可操作的动物屠宰场的屠宰场工作人员进行了评估，评估了以下三个主要参数：（1）雇用受过训练和忠诚的工人；（2）适当的环境和适当的设计参数；（3）适当的构造，设备和工具。现代屠宰场中只有30％雇用了受过训练的人员以适当的方式处理牲畜，而传统屠宰场的这一数字为零。关于羊的电击晕应用，现代屠宰场的动物福利质量显着高于传统屠宰场（P <0.05）。在九座配有卸料平台和牲畜屠宰场的屠宰场中，分别符合标准的占55％和35.7％。关于佣金参数和入口大厅，现代植物比传统的屠宰场高（P> 0.05）。建议为相关的兽医和屠宰场工作人员提供培训课程，以及升级屠宰场的建设。与传统的屠宰场相比，现代植物的占有率更高（P> 0.05）。建议为相关的兽医和屠宰场工作人员提供培训课程，以及升级屠宰场的建设。与传统的屠宰场相比，现代植物的占有率更高（P> 0.05）。建议为相关的兽医和屠宰场工作人员提供培训课程，以及升级屠宰场的建设。
