摘要
本文是用肉眼和光镜研究珍珠鸡(Numlda m(?)lcagris)胚胎发育过程各阶段的形态学。珍珠鸡胚发育的规律、各器官结构形成的次序,均与鸡胚相似。胚胎在孵化的前10天增重较慢,平均每天约增重0.12g。孵化10天后,胚体重明显增快,平均每天约增重2.2g。胚体长度的变化与胚龄也有一定关系。根据珍珠鸡胚胎发育过程各阶段的形态学变化和胚重情况,可将胚胎发育过程大致分为前、中、后三期,这对孵化时的温度调节有重要参考意义。
The embryonic morphological development of the guinea fowl at different stages was observed with the naked eye and microscope. The sequence of organ formation in the guinea fowl was similar to that of the chicken .The weights of early embryos within 10 days of incubation increased slowly, but rose fast after 10 days of incubation up to hatching, According to the state of the embryonic development and weight increase, the process of embryonic development could be divided into three it ages, early, middle and late.
