| 摘 要： | 通过测定鸡蛋蛋白、蛋黄及胚胎中钙、粗蛋白和粗脂肪含量,探讨孵化期间蛋内组成成分的变化规律.结果表明: 胚胎发育过程中蛋白提供20.2%的钙,蛋黄提供10.0%的钙,蛋白和蛋黄钙含量的变化具有一定的互补性;胚胎中钙含量不断增加.蛋白中粗蛋白含量高,粗脂肪含量低,粗蛋白与粗脂肪含量变化趋势基本相反.除12胚龄外,蛋黄中粗脂肪含量不断降低; 18～21胚龄是脂肪代谢旺盛期.胚胎粗蛋白含量不断降低,粗脂肪含量不断增加,两者呈负相关.

| Abstract: | The changing regulation of the composition of different parts inside egg during incubation was studied through measuring the content of calcium,crude protein and crude fat.The results were as following: the albumen provided 20.2% calcium for embryo and the yolk provided 10.0%.The change of albumen and yolk calcium content supplemented each other to some degree.The calcium content of the embryo increased continuously.The crude protein content in albumen was high,but crude fat was low,the changing trend was o... |
