为了解国内、外两类猪种肌肉生长发育及血清中相关细胞因子含量差异，以我国特有的藏猪和国外杜洛克猪作为研究对象，采用酶联免疫分析法（ELISA）测定6月龄藏猪、杜洛克猪血清中胰岛素样生长因子-1（IGF-1）、胰岛素样生长因子结合蛋白-3（IGFBP-3）的含量及肌纤维面积（CSA）。结果显示：藏猪血清中IGF-1含量及CSA均极显著低于杜洛克猪（P<0.01），IGFBP-3含量极显著高于杜洛克猪（P<0.01）；CSA与IGF-1含量间呈极显著正相关，与IGFBP-3间呈极显著负相关，说明IGF-1对猪背最长肌生长发育有促进作用，而IGFBP-3可能有抑制作用。

In this article, Tibet and Duroc pigs were selected to investigating the differences of growing development of muscle and content of correlated cell factors in plasma of domestic and foreign pigs. The content of insulin- like growth factor-1(IGF-1)and insulin-like growth factor binding protein 3 (IGFBP-3) in plasma of Tibet and Duroc pigs of 6 month were menstruated by enzyme-linked immunosorbent assay (ELISA), cross sectional area of muscle fiber (CSA) of those two pigs were also surveyed. The results showed that the content of IGF-1 in plasma and CSA of Tibet pigs both were significantly lower than Duroc pigs(P<0.01), while the content of IGFBP-3 in plasma was significantly higher than Duroc pigs (P<0.01) . The CSA was significantly positively correlated to IGF-1 content,but significantly negative correlated to IGFBP-3 content.These indicated that IGF-1 can promote growing development of porcine longissimus dorsi, whereas IGFBP-3 may inhibit that.
