摘要 试验研究谷氨酰胺对免疫应激仔猪肌肉中理化指标的影响。采用2×2析因试验设计,选用28 d平均体重7 kg的长白×约克夏断奶仔猪96头,按体重相近原则随机分为4组。对照组(Ⅰ组)、免疫应激组(Ⅱ组)饲喂基础日粮,断奶后7 d分别注射100μg/kg BW生理盐水、LPS;谷氨酰胺组(Ⅲ组)、谷氨酰胺+免疫应激组(Ⅳ组)饲喂含谷氨酰胺浓度为1.2%的日粮,断奶后7 d分别注射100μg/kg BW生理盐水和LPS。试验期14 d。结果表明:LPS应激极显著提高了仔猪肌肉中乳酸含量(P<0.01),极显著降低了总蛋白、丙氨酸氨基转移酶、过氧化氢酶、谷胱甘肽含量(P<0.01),而谷氨酰胺的添加缓解了这几项指标的显著变化,且日粮类型与LPS应激均存在交互作用(P<0.01),说明日粮中添加谷氨酰胺可缓解免疫应激,对免疫应激仔猪具有保护作用。
