牛只运输时坡道装卸对其体温和行为的影响

为评价牛对装卸的应激反应，以期为改善牛装卸方式、丰富牛运输应激理论、完善动物运输相关标准提供依据，对有坡道和无坡道装卸条件下牛的体温和行为进行观测。结果表明，有坡道和无坡道2种装卸方式对牛均有刺激，且有坡道组刺激更强烈，表现为体温显著升高和逃跑、攻击和哞叫等应激行为反应；牛抵御装卸刺激的行为策略是首先选择逃跑，受阻后是攻击，最后是哞叫。该研究可为评价和改善牲畜装卸方式提供参考。

Effects of handling methods on body temperature and behavior of cattle during transportation

To assess the stress action of cattle to handling, and then to provide reference to progress cattle handling, enrich the theory of transport stress of cattle, perfect the animal transport standard, body temperature and behavior of cattle in conditions of with and without chute in highway transport were measured. The results revealed that both of handlings with and without chute were stressful, with chute was more stressful than without chute, stress responses of cattle included the elevated temperature and behavior of escape, aggression, vocalization, and behavior strategy to resist handling stress were firstly escape, secondly aggression after escape were hindered and finally vocalization. The results of this study are valuable for evaluating and progressing animal handling mode.
