摘　　要：采用驱赶法使乳猪产生应激,探讨金属硫蛋白对应激猪血清与肌肉中非酯化脂肪酸及肌乳酸含量的影响。结果表明:在应激状态下,金属硫蛋白可使血清和运动初期肌肉中的非酯化脂肪酸含量升高,肌乳酸的生成降低,因而可增强有氧代谢,改善机体对运动负荷的压力,提高动物的抗应激能力,因此金属硫蛋白对乳猪具有一定的应激保护作用。Suckling pigs with driving stimuli to move suffer from stress.To explore effects of different doses of Metallothionein on nonesterified fatty acids content in the blood and muscle and sarcolactic acid of roast pigs under stress,this study was conducted.Results showed that metallothionein could increase the nonesterified fatty acids content in serum and muscle of early movements and reduce the sarcolactic acid content in muscle.Therefore,metallothionein can increase aerobic metabolism and improve the body of the exercise load pressure,enhancing the ability of anti-stress animals.In short,the metallothionein has a function of protecting suckling pigs from stress.
