肉牛运输应激研究进展

Research progress on transport stress in beef cattle

运输应激会对动物的生产、内分泌、肉品质以及免疫功能等造成一定的影响。肉牛在经过长途运输后会造成瘤胃功能减退,瘤胃微生物菌群失调,进而导致肉牛采食量、反刍次数减少,体温升高,体重下降等。文章综述了运输应激对肉牛神经内分泌、生化指标、肉品质、免疫、抗氧化功能等的影响,概述了缓解肉牛运输应激的相关措施,以期为肉牛运输应激后续的相关研究及生产过程中实际应用提供参考。

Transport stress can have certain effect on animal production,endocrine,meat quality and immune function.After long-distance transportation of beef cattle,rumen function will be decreased and rumen microflora will be disturbed,which will lead to reduced feed intake and rumination times,increased body temperature and weight loss.The paper reviews the effect of transport stress on neuroendocrine and biochemical indexes,meat quality,immune,antioxidant function of beef cattle,summarizes relevant measures to alleviate transport stress of beef cattle,in order to provide reference for subsequent research and practical application of transport stress in beef cattle production.
