摘要：

为了比较莱茵鹅和朗德鹅的生产性能差异以及经过多个世代育种后各自生产性能的变化,测定了莱茵鹅和朗德鹅体质量和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:除初生体质量外,朗德鹅体质量显著高于莱茵鹅。在中后期,朗德鹅公、母鹅体质量差异不显著,莱茵鹅公鹅体质量显著高于母鹅。3种生长曲线模型均能很好地拟合2个鹅品种早期生长发育规律,以Gompertz模型拟合生长曲线效果较佳,朗德鹅的极限体质量、拐点体质量大于莱茵鹅,2个鹅品种的拐点周龄几乎一致。大多数朗德鹅的体尺指标显著性高于莱茵鹅。朗德鹅的生产性能明显优于莱茵鹅,2个鹅品种经过多世代育种后仍保持了较高的生产性能。

摘要：

The purpose was to compare performance between Rhine goose and Landes goose,and to detect the change of performance about the two breeds after several generations of breeding.The body-weight of earlier stage and body-size for 10th weeks of Rhine goose and Landes goose were detected.Three nonlinear models were used to fit the growth curve.The results showed that,except for birth weight,the body-weight of Landes goose was significantly higher than that of Rhine goose.The body-weight of Landes goose did not have significant difference between sex at the mid and late stage.The body-weight of male Rhine goose was significantly higher than female.Three growth curve models could all imitate the early growth regularity of the two goose breeds.The Gompertz model generated the best growth curve.The maximum weight and inflection point weight of Landes goose were higher than Rhine goose.The inflection age of two goose breeds was the same.Most body-size indexes of Landes goose were significantly higher than Rhine goose.The performance of Landes goose was better than Rhine goose.The two breeds still had high performance after several generations of breeding.
