138 weaned pigs have been examined for clinical and immunological parameters as well as cortisol from the day before to eight days after surgery (scrotal-hernias, cryptorchidisms). Important alterations in cortisol concentrations were found neither by the surgical intervention itself nor by accompanying measures like food restraint (48 hours), diagnostic blood sampling (venipuncture) and infectious prophylaxis (chemoprophylaxis, para-immunization). Therefore, chronically pathological stress reactions following routine surgical interventions may be excluded. Single elevations of serum cortisol above the physiological range (8-60 ng/ml) on the day after surgery without typically clinical stress symptoms and correlations to the cell mediated immunity may be interpreted as positive physiological stress reactions in connection with an elevated efficiency.
对138头断奶仔猪进行了检查，从手术前一天到手术后八天，观察其临床和免疫学参数以及皮质醇水平（手术类型为阴囊疝、隐睾症）。无论是手术本身，还是诸如禁食（48小时）、诊断性采血（静脉穿刺）和感染预防（化学预防、准免疫）等伴随措施，均未发现皮质醇浓度有重要变化。因此，可以排除常规手术干预后出现慢性病理应激反应的可能性。术后第一天血清皮质醇单次升高超过生理范围（8 - 60 ng/ml），但无典型临床应激症状，且与细胞介导免疫无相关性，这可被解释为与效率提高相关的阳性生理应激反应。
