父母代固始鸡空肠的发育形态学研究

Study on the Developmental Morphology of the Jejunum in the Parental Line of Gushi Chickens

应用大体解剖学与组织学切片技术,对父母代固始鸡空肠的发育形态学进行了研究,并用Logistic曲线方程对空肠重量增长进行拟合。结果表明:空肠的长度、重量、周长和空肠的绒毛长度、绒毛宽度、隐窝深度、肠腺宽度与周龄呈正相关;空肠指数、空肠的肠腺密度与周龄呈负相关;Logistic方程可以很好地拟合空肠的增重曲线(公鸡R2=0.9968,母鸡R2= 0.9891),公鸡的空肠增重拐点是8.26周,母鸡是8.64周。

The developmental morphology of the jejunum was observed with the technique of anatomy and histological section in the parental line of Gushi Chickens. The results indicated that the length, weight, girth, the villus length of jejunum, the width of the villus, recess depth and intestinal gland width were positive correlated to the age ,and ratios of the jejunum weight to body weight and destiny of gl. intestinales were negative correlated to it. The logistic curve equation could accord with the weight growth of the jejunum（Male： R^2 = 0. 9892 ,Female： R^2 =0. 9968）.
