摘　　要：为探明淮南猪与长白猪脂肪代谢酶及血清中脂联素的发育差异,对45日龄、90日龄、135日龄和180日龄健康长白猪和淮南猪进行血清中脂联素含量、肌内脂肪含量及脂肪代谢酶测定。结果表明:相同品种猪的肌内脂肪含量随着猪日龄的增加而增加;相同日龄不同猪种间肌内脂肪含量淮南猪显著高于长白猪(P<0.05);同一品种猪血清中脂联素的含量随日龄增加而增加,135日龄和180日龄分别与45日龄间差异显著;淮南猪和长白猪脂肪组织中的脂肪酸合成酶(FAS)和激素敏感脂酶(HSL)含量随日龄的增加而增加,均以180日龄最高;脂联素及脂肪代谢酶变化趋势均随日龄的增加而增加,具有强脂肪沉积能力。The serum adiponectin and intramscular fat content,and FAS and HSL activity of health Huainan and Landrace pigs with45d age,90d age,135d age and180d age were detected to explore development difference in fat metabolic enzymes and serum adiponectin between Huainan and Landrace pigs.Results:The intramscular fat content of the same pig variety increases with increase of day age and the intramscular fat content of Huainan pigs is higher than Landrace pigs under the same day age(P<0.05).The serum diponectin content of the same pig variety increases with increase of day age and the serum diponectin content of the same pig variety with135d age and180d age is higher than the same pig variety with45d age significantly.The FAS and HSL content in fat tissue of Huainan and Landrace pigs increases with increase of day age and the FAS and HSL content in fat tissue of Huainan and Landrace pigs with180d age is the highest.The variation trend of adiponectin and fat metabolic enzymes increases with increase of day age,which indicates that the fat deposition capacity of pigs increases with increase of day age.
