| 摘 要： | 比较泰和鸡和ＡＡ（Ａｒｂｏｒ Ａｃｒｅｓ）肉鸡血清生长激素（ＧＨ）含量和生长激素结合蛋白（ＧＨＢＰ）的结合活性，发现两品种鸡出雏时血清ＧＨ水平均较低，５日龄时ＧＨ均有显著上升（Ｐ＜０．０１）。此后泰和鸡保持上升趋势，在３５日龄ＧＨ达到最高值；而ＡＡ鸡在５日龄后血清ＧＨ水平上升幅度较小，日龄间差异不显著。１日龄和３５日龄时，泰和鸡血清ＧＨ水平显著高于同日龄的ＡＡ肉鸡，与两者体重的差异刚好相反。血液Ｇ

| Abstract: | The plasma levels of growth hormone(GH)and binding activities of serum growth hormone binding protein(GHBP)of Taihe chickens were measured in comparison with that of Arbor Acres(AA)chickens at 1(D1),5,10,35 and 50 days of age.Plasma GH concentrations were low at hatch,followed by a significant increase at D5 in both strains of chicken.GH plasma concentrations in Taihe chicken were keeping increase thereafter till D35 when the peak value was reached.In AA chickens,however,no significant developmental changes in GH plasma levels were observed after D5 in spite of a tendency of up-regulation.Taihe chickens exhibited significantly higher plasma GH levels than AA chickens at D1 and D35,being inversely correlated with body weight.Serum GHBP activities were high at hatch,followed by a significant decrease at D5 in both strains of chicken.An up-regulation was observed in both strains of chicken from D35 to D50 when the growth rate was declined.Serum GHBP activities in Taihe chicken were significantly lower than that of AA chickens at D5,D10 and D50.A clear negative relationship was observed between serum GHBP activities and plasma GH levels. |
