With this study, it was aimed to determine the stress effects that can be caused by transporting and altitude in sheep. Karayaka sheep were used in the study. The live weight of the sheep (n=30) while hungry was determined before transport and sea level. Average live weight was determined as 55.64 ± 4.66 kg. Blood samples were collected just before (sea level) and just after transport (1500 meters above sea level). Transportation distance was approximately 182 km and duration was 5 hours. According to the findings, cortisol was not affected by transport stress and altitude (p>0.05) and Triiyodotironin (T3) (p<0.039) and Tyrosine (T4) (p<0.000) were affected significantly. Malondialchehyche (MDA), which is one of the oxidative stress parameters, was significantly affected (p<0.039) and Protein Carbonyl (PC) values were not affected by transport and altitude (p>0.184). As a result of this study, it was determined that transportation and altitude in sheep causes stress. Stress-reducing measures should be taken in the exposure of sheep to altitude differences and in transportation. Antioxidant nutritional supplements should be made in order not to negatively affect the meat quality in sheep.

运输和海拔高度对绵羊激素和氧化应激参数的影响

这项研究旨在确定绵羊运输和海拔高度可能引起的胁迫效应。这项研究使用了Karayaka绵羊。在运输和海平面上升之前确定饥饿时绵羊的活重(n = 30)。平均活重确定为55.64±4.66千克。在运输之前(海平面)和运输后(海拔1500米)采集血液样本。运输距离约为182公里,持续时间为5小时。根据研究结果,皮质醇不受运输压力和海拔高度的影响(p> 0.05),而三碘dot铁蛋白(T3)(p <0.039)和酪氨酸(T4)(p <0.000)受到显着影响。氧化应激参数之一的丙二醛(MDA)受显着影响(p <0。039)和蛋白质羰基(PC)值不受运输和海拔高度的影响(p> 0.184)。这项研究的结果是,确定绵羊的运输和海拔高度会造成压力。在绵羊暴露于海拔差异和运输中时,应采取减轻压力的措施。应制作抗氧化营养补品,以免对绵羊的肉质造成负面影响。
