This study investigated the effects of an essential oil mixture (EOM; Eucalyptus globulus labill, Tymus vulgaris, Cymbopogon nardus, and Syzgium aromaticum) added to drinking water on temperature-stressed broilers. The performance parameters (body weight, average daily weight, feed intake, and feed conversion ratio), meat quality, and thiobarbituric acid-reactive substances (TBARS) were evaluated. In a 42-d study, 400 Ross-308 male chickens (1-d-old) were randomly assigned to 8 different groups (n = 50), each containing 4 subgroups (n = 8) (22°C Control (C), C + 250 mL/1,000 L, C + 500 mL/1,000 L, C + 750 mL/1,000 L), 36°C (stress control (SC), SC + 250 mL/1,000 L, SC + 500 mL/1,000 L, SC + 750 mL/1,000 L). Adding 750 mL/1,000 L at 22°C and 250 mL/1,000 L at 36°C was more beneficial to the fattening performance parameters than those in the control group. EOM reduced liver weight but increased abdominal fat in the SEOM-250 groups but did not affect other organ weights. EOM had no effect on the TBARS or the b* color parameter while it augmented the a* and L* coordinates of meat color.

这项研究调查了添加到饮用水中的精油混合物（EOM；球状桉树，寻常的鼠耳草，Cymbopogon nardus和Syzgium aromaum）对温度紧张的肉鸡的影响。评估了性能参数（体重，平均日重，饲料摄入量和饲料转化率），肉品质和硫代巴比妥酸反应性物质（TBARS）。在一项为期42天的研究中，将400只Ross-308雄性鸡（1天大）随机分为8个不同的组（n = 50），每组包含4个亚组（n= 8）（22°C控制（C），C + 250 mL / 1,000 L，C + 500 mL / 1,000 L，C + 750 mL / 1,000 L），36°C（压力控制（SC），SC + 250毫升/ 1,000升，SC + 500毫升/ 1,000升，SC + 750毫升/ 1,000升）。与对照组相比，在22°C下添加750 mL / 1,000 L和在36°C下添加250 mL / 1,000 L对增脂性能参数更有利。EOM可减轻SEOM-250组的肝脏重量，但增加腹部脂肪，但不影响其他器官重量。EOM对TBARS或b *颜色参数没有影响，而增加了肉色的a *和L *坐标。
