摘　　要：测定皖西白鹅和四川白鹅早期体重、10周龄体尺,用3种非线性生长模型拟合其生长曲线.结果表明：四川白鹅初生重显著高于皖西白鹅.从第2周龄开始皖西白鹅公鹅体重显著性高于四川白鹅公鹅.除第6、10周外,从第3周龄开始皖西白鹅母鹅体重显著性高于四川白鹅母鹅.Logistic模型拟合生长曲线效果最佳,与四川白鹅相比,皖西白鹅的极限体重高、拐点体重大,拐点周龄早.公鸭的拐点周龄要比母鸭推迟0.1 ～0.2周.皖西白鹅公鹅10周龄体料长、龙骨长、胫长、半潜水长显著性高于四川白鹅公鹅;母鹅体斜长、半潜水长显著高于四川白鹅母鹅,但是胫围显著低于四川白鹅母鹅.The body-weight and body-size of goose were detected,which contained Wanxi white goose and Sichuan white goose.Three nonlinear curves were used to fit the growth curve.The results indicated that the initial body-weight of Sichuan white goose was significantly higher than that of Wanxi white goose.The body-weight of Wanxi white goose （male） was significantly higher than Sichuan white goose （male） from two week-old to ten week-old.Except for the sixth and tenth week,the body-weight of Wanxi white goose （female） was significantly higher than that of Sichuan white goose （female） at the beginning three week-old.The logistic model generated the best growth curve.The mature weight,inflection point weight of Wanxi white goose was higher than that of Sichuan white goose,but the inflection age of Wanxi white goose was earlier than that of Sichuan white goose.The length of body slope,fossil bone,shank and half-diving of Wanxi white goose （male） were significantly higher than Sichuan white goose （male）.The length of body slope and half-diving of Wanxi white goose （female） were significantly higher than that of Sichuan white goose （female）,shank circumaference was lower than that of Wanxi white goose （female）.
