黑龙江籽鹅早期生长发育规律的研究

Study on the Early Growth and Development of Heilongjiang Zi Goose

试验选择健康1日龄籽鹅120只，在当地条件下饲养到12周龄。拟合出体重、日增重和相对增重曲线方程（R^2〉0．9）。试验表明：1—3周龄生长强度最大，4～8周龄体重增加较快；6周龄与10周龄体重呈强正相关（r=0．858）；4周龄左右是胫长和胫围生长发育的旺盛时期；9周龄以后随着增重的减少，饲料转化率降低。

120 healthy Heilongjiang zi geeze were selected and reared under the similar conditions until 12 weeks. The curvefit equations（R2 〉 0.9）about body weight, daily gain and relative growth were acquired. The experiment indicated that the growth intension was the highest weight from 1 to 3 weeks, and the body gain was faster between 4 and 8 weeks; The body weight was significantly correlated（r = 0. 858） between 6 and 10 weeks; The length and diameter of shin bone reached its climax at bloom on the 4th week; The feed inversion rate was reduced with the decreased weight gain after 9 weeks.
