| 摘 要： | 本文比较研究了日粮中添加精氨酸(L-Arginine,Arg)和精氨酸生素(Arginine activator additive,AAA)对早期断奶仔猪氧化应激的影响.试验选用84头21日龄断奶的长X大仔猪(5.56±0.07 kg),共12栏,分为3个处理组(4栏/处理,7头/拦).分别饲喂基础日粮(SD)、SD+AAA(0.08%)或SD+Arg(0.6%),试验期为7d.结果表明:与对照组相比,Arg和AAA添加组中血清Arg浓度、平均日增重(ADG)及肠道重均显著增加(P<0.05),血清皮质醇(COR)、丙二醛(MDA)及尿素氮(BUN)浓度显著降低(P<0.05);与对照相比,AAA添加组血清谷胱甘肽(GSH)水平显著增加(P<0.05),腹泻率、血清谷丙转氨酶(ALT)活性及肠粘膜MDA浓度显著降低(P<0.01),而Arg添加组中上述四者无显著变化,且Arg添加组中空肠黏膜GSH水平显著降低(P<0.01).与Arg添加组相比,AAA添加组中血清GSH、铜锌过氧化物歧化酶(CuZn-S00)及黏膜GSH显著增加(P<0.05),并且肠粘膜MDA降低了32.9%.因此,日粮添加AAA或Arg均促进断奶仔猪的生长性能的提高,缓解断奶引起的氧化应激,但与Arg相比,AAA不仅更有效降低了MDA的水平,而且提高了断奶仔猪的抗氧化系统功能,从而更好的缓解了氧化应激,缓解了肠黏膜的氧化损伤.
