设施养殖肉牛应激反应综合症防治探讨

肉牛应激反应综合症在现代规模化设施养殖条件下发病率高,机体为动员大量能量来对付应激原的刺激而使分解代谢增强,合成代谢降低,出现负氮平衡,适应机能破坏,生理功能降低,内分泌和代谢失调,引发各系统机能紊乱甚至死亡.在前期病因和发病机理研究的基础上,对设施养殖肉牛应激反应综合症防治方法进行了探讨,提出了添加抗应激药物等综合防治措施.

Discussion on Stress Response Syndrome of Beef Cattle under Facility Cultivation

Beef cattle had high-incidence of stress response syndrome, under the conditions of modernfacility cultivation. Because organism mobilized a lot of energy to deal with stress of original stimulus, itincreased catabolism and reduced anabolism. Therefore, the negative balance of ammonia came out, thusthe function of adaptation might be damaged, the function of physiological were reduced and endocrine andmetabolism disordered. It resulted the function of each system disordered and even led to die finally. Basedon the studies on former etiology and pathogenresponse syndrome of beef cattle under facilityesis, this article discussed the control methods of the stresscultivation, as well as it put forward some comprehensivecontrol measures, such as adding anti--stress drugs and so on, which would provide some reference forfarms and veterinarians.
