摘要
对不同饲养方式下狮头鹅9周龄的体重变化进行了曲线方程拟合。结果,不同饲养方式下狮头鹅体重增长趋势符合Logistic生长曲线,拟合优度R2均在0.995以上。舍饲条件下,狮头鹅的周平均日增重明显地高于放牧加补饲的鹅。
Curve equations were establish ed to simulate the weight growth of Lionhead geese under two feeding manners bef ore9weeks of age.The results showed that the weight growth of Lionhead geese under both feeding manners fitted the Logistic growth curve,with the goodness o f fit(R 2 )over0.995.The geese fed in the sheds gained obviously more weight p er day within a week than those fed in the fields.
