Plasma growth hormone (GH) and prolactin concentrations were measured between 1 and 24 weeks of age in both sexes of a laying strain of chickens and from 1 to 9 weeks of age in broiler cockerels. 2. GH and prolactin concentrations were highest in young birds and higher in males than in females. 3. In both sexes GH and prolactin concentrations were correlated inversely with age and body weight and positively with relative weight gain. 4. Differences in growth rate between broilers and layers were related to differences in blood GH concentrations. 5. Water deprivation for periods of 6, 12, 18 or 24 h increases plasma prolactin markedly but did not affect GH secretion significantly.
对蛋鸡品系的雌雄鸡在1至24周龄期间以及肉用小公鸡在1至9周龄期间的血浆生长激素（GH）和催乳素浓度进行了测定。2. 生长激素和催乳素浓度在幼鸟中最高，且雄性高于雌性。3. 在雌雄两性中，生长激素和催乳素浓度均与年龄和体重呈负相关，与相对体重增加呈正相关。4. 肉鸡和蛋鸡生长速率的差异与血液中生长激素浓度的差异有关。5. 6、12、18或24小时的断水会显著增加血浆催乳素，但对生长激素分泌没有显著影响。
