| 摘 要： | 本研究用隆昌鹅、太湖鹅和新太湖鹅(隆昌鹅作父本， 太湖鹅作母本所培育的后代)各60只，在粗放条件下饲养到70日龄，测定了三种鹅各周龄的 体重及双周体尺，并用Richards生长曲线方程拟合了鹅的生长规律。结果证明：太 湖鹅4周龄左右为生长高峰，而隆昌鹅和新太湖鹅生长高峰周龄分别在6周龄与7周龄。新太 湖鹅 生长速度已基本接近隆昌鹅。Richards生长曲线方程能很好地拟合鹅的生长发育规 律，拟合精度（R2)均大于0．9988。6周龄是新太湖鹅骨骼、胸宽、胸深生长发育 的旺盛期。

| Abstract: | An experiment was carried out on body weight（everyweek） and size（ biweekly） of Longchang、Taihu and New Tai hu goose．New Taihu goose is the offsprin g of Longchang（male parent） and Taihu（fe male parent）．All geese for measure were reared under similar conditions until 10 weeks．The results showed：growth peak of Taihu goose appears at the age of 4week s，but the growth peaks of Longchang goos e and New Taihu goose turn up at the age of 6 and 7 weeks respectively．Growth of New Taihu goose has virtually reached t hat of Longchang goose，which shows its g ood growing capability．Richards model ca n be used in describing growth-developme nt in three strains（R2＞0．998 8）．New Tai hu goose grows fastest at 6 weeks of age than other weeks in bone and breast wid th and depth． |
