摘　　要：动物泌乳受多种激素和因子的调节 ,除催乳激素 (PRL)外 ,还有生长激素 (GH)、胰岛素 (Insulin)、甲状腺素 (T3、T4)及胰岛素样生长因子 (IGF Ⅰ )等。通过对泌乳期二花脸猪和大白猪血浆GH、Insulin、T3、T4和IGF Ⅰ含量的比较 ,结果是大白猪 (LWS)血浆GH总体水平、基线水平、峰强度均高于二花脸猪 (EHS) ,分别高 1 9.84%、2 0 .5 4 %和 69.88% ,血浆Insulin、IGF Ⅰ均显著高于二花脸猪 (P <0 .0 5 ) ,分别高 5 0 .46%和 5 5 .45 % ,而二花脸猪血浆T3、T4显著高于大白猪 (P <0 .0 5 ) ,分别高 1 9.42 %和 1 7.89%。Lactation of animals was regulated by many hormones and growth factors,such as growth hormone(GH), insulin like growth factorⅠ(IGF Ⅰ),insulin and thyroxine(T 3,T 4). Comparing GH , IGF Ⅰ,insulin and T 3,T 4 in lactating Erhua sows with those in Large White sows,the results showed that levels of GH, IGF Ⅰ and insulin in plasma of lactating Large White sows were obviously higher than those in plasma of lactating by 19.84%,55.45% and 50.46%(P<0.05), but levels of T 3,T 4 were lower by 19.42% and 17.89%(P<0.05).
