Abstract

The roles of chronological age, body weight and body composition in the initiation of sexual maturation of Japanese quail (Coturnix coturnix japonica) were investigated by imposing an inhibitory photoperiod (IP), and by the intramuscular injection of turkey growth hormone (GH) or antisera to turkey growth hormone (AGH). 2. Absence of sexual maturity in the IP treatment was accompanied by reduced testis and ovary-oviduct weights, and an increased breast muscle weight expressed as a proportion of body weight. 3. Antisera to turkey growth hormone (AGH) did not completely inhibit the metabolic activities of endogenous GH. 4. The roles of chronological age, body weight and body composition in the initiation of sexual maturity were inseparable.

摘要

通过施加抑制性光周期（IP）以及肌肉注射火鸡生长激素（GH）或抗火鸡生长激素抗血清（AGH），研究了日龄、体重和身体组成在日本鹌鹑（Coturnix coturnix japonica）性成熟启动过程中的作用。2. IP处理中未出现性成熟，同时睾丸和卵巢-输卵管重量减轻，胸肌重量占体重的比例增加。3. 抗火鸡生长激素抗血清（AGH）并未完全抑制内源性GH的代谢活性。4. 日龄、体重和身体组成在性成熟启动过程中的作用是不可分割的。
