| 摘 要： | 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(R2>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。

| Abstract: | 120 healthy Heilongjiang zi geeze were selected and reared under the similar conditions until 12 weeks.The curvefit equations(R~2>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. |
