The pronounced episodic release of chicken growth hormone (cGH) in male broiler chicks, as well as its peak interval of about 90 min was confirmed in this study. 2. Lines selected for 6-week body weight (GL line) or for food conversion between 3 and 6 weeks of age (FC line) not only differ in the selection criteria but also in percentage abdominal fat. 3. The overall mean plasma GH concentration was higher in the FC line in both experiments, and this was only caused by peak amplitudes which were almost twice as high as in the FC line. Peak intervals were identical in both selected lines. 4. These observations suggest that decreased abdominal fat and increased protein efficiency may be genetically linked to increased plasma GH peak amplitude. This, and earlier observations on the effectiveness of pulsatile administration of cGH on the growth of broilers suggest that the biological function of GH may depend on its secretory pattern rather than its mean concentration in plasma.

本研究证实了雄性肉鸡体内鸡生长激素（cGH）明显的间歇性释放及其约90分钟的峰值间隔。2. 选择6周龄体重（GL系）或3至6周龄食物转化率（FC系）的品系不仅在选择标准上不同，腹部脂肪百分比也不同。3. 在两个实验中，FC系的总体平均血浆生长激素浓度均较高，这仅仅是由峰值幅度引起的，其峰值幅度几乎是GL系的两倍。两个选择品系的峰值间隔相同。4. 这些观察结果表明，腹部脂肪减少和蛋白质效率提高可能与血浆生长激素峰值幅度增加存在遗传联系。这一点，以及先前关于脉冲式注射cGH对肉鸡生长有效性的观察结果表明，生长激素的生物学功能可能取决于其分泌模式而非血浆中的平均浓度。
