Abstract

The importance of egg albumen content in whole-body protein synthesis was investigated in developing chicken embryos by using lines genetically selected for high and low albumen contents and by removing albumen from eggs before incubation. 2. Whole-body protein synthesis was estimated by injecting L-[15N]-phenylalanine intravenously on day 12 of incubation. 3. Embryos from high albumen eggs had higher whole-body protein synthesis rates than those from low albumen eggs. 4. Whole-body protein synthesis was reduced by the removal of albumen from eggs before incubation. 5. It was concluded that albumen content per se was of crucial importance in regulating whole-body protein synthesis in chicken embryos during incubation.

摘要

通过使用高蛋清含量和低蛋清含量的遗传选择品系以及在孵化前从鸡蛋中去除蛋清，研究了蛋清含量在发育中的鸡胚全身蛋白质合成中的重要性。2. 通过在孵化第12天静脉注射L-[15N]-苯丙氨酸来估计全身蛋白质合成。3. 来自高蛋清含量鸡蛋的胚胎比来自低蛋清含量鸡蛋的胚胎具有更高的全身蛋白质合成率。4. 在孵化前从鸡蛋中去除蛋清会降低全身蛋白质合成。5. 得出的结论是，蛋清含量本身在调节孵化期间鸡胚的全身蛋白质合成中至关重要。
