| 摘 要： | 对乌骨鸡胚胎发育过程中卵内各组成成分(蛋清、蛋黄、胚胎)在不同胚龄(即入孵的第0、3、6、9、12、15、18d和出壳)时蛋白质、脂肪含量变化进行测定与分析．结果表明：在不同胚龄时，蛋清中蛋白质含量显著高于蛋黄，蛋黄中脂肪含量始终高于蛋清；而胚胎中的蛋白质、脂肪逐渐增加。另外，胚胎发育过程中胚胎蛋白质的主要来源是蛋黄中的蛋白质，说明蛋黄是禽类胚胎发育过程中营养需要的主要来源。

| Abstract: | Protein and fat content variation in albumen, yolk and embryo of silkies fowl eggs during embryo development were analyzed. The results showed that: albumen has remarkable high protein content than yolk while yolks always have high fat content than albumen. Protein and fat content increase progressively in embryos at different age such as the first, third, sixth, ninth, twelfth, fifteenth, eighteenth day during incubation and produce from egg shell.In addition, protein which is required in embryo development is mainly from protein of yolk, these results confirmed the concept that yolk is the primary nutrition source of embryo development of poultry. |
