摘　　要：为了研究定安鹅及其杂交后代的生长规律,为其提供更科学的饲养方案,以满足其各阶段不同生长发育需要,发挥最大生产性能,试验选取定安鹅、浙定F1代(浙东白鹅♂×定安鹅♀)、阳定F1代(阳春鹅♂×定安鹅♀)公母鹅各50只,相同饲养管理条件下分别测定其每周体重,并采用Gompertz非线性生长模型对其生长发育曲线进行拟合。结果表明:定安鹅及其杂交后代生长发育曲线与Gompertz模型拟合良好,拟合度在0.99以上;定安鹅与浙东白鹅及阳春鹅的杂交后代生长性能较定安鹅均有较大提升,生长周期也明显缩短。说明用Gompertz模型进行定安鹅及其杂交后代生长发育曲线拟合可作为研究其生长发育规律的参考。To explore the growth rules, provide more suitable feeding plan, and present the best production performances of Ding’an goose, Zhe Ding F1 goose(Zhedong White goose male× Ding’an goose female), and Yang Ding F1 goose(Yangchun White goose male× Ding’an goose female), the body weights of 100 geese(with male and female equally) were measured once a week, and the growth curves of each line were fitted using Gompertz model. The results showed that the growth curves of three lines were all well fitted with the fitting relevance(R^2), and were higher than 0.99. In addition, Zhe Ding F1 goose and Yang Ding F1 goose had the better growth performances than Ding’an goose, and their growth periods were also shorter than that of Ding’an goose. It indicated that the growth curves of Ding’an goose, Zhe Ding F1 goose and Yang Ding F1 goose could be well fitted using Gompertz model, while the growth curves could be used to analysis the growth rules of geese of Ding’an goose, Zhe Ding F1 goose and Yang Ding F1.
