摘要(Abstract)：
[目的]探讨中外品种仔猪抗应激能力差异性。[方法]分别选用(12.6±0.7)kg的莱芜猪和大约克猪的断奶仔猪6头,从腹腔注射200μg/kg的脂多糖(LPS),于注射前1 h和注射后2、4、7、10 h分别采血测定血浆白介素-1β和皮质醇的含量,并建立免疫应激模型,监测免疫应激后莱芜猪和大约克猪仔猪2~10 h内血浆IL-1β和皮质醇含量的变化。[结果]在免疫应激下,大约克猪和莱芜猪之间具有显著(P<0.05)或极显著(P<0.01)的品种差异性。LPS刺激后2 h莱芜猪IL-1β的水平显著小于大约克猪,LPS刺激后的2、4和7 h莱芜猪的皮质醇水平显著或极显著低于大约克猪。[结论]莱芜猪的抗免疫应激能力强于大约克猪。
