摘要: 本试验采用天府肉鹅父系、母系为材料,测定了9-17周龄绒羽的生长发育及理化特性。结果表明,父系的产线性能优于母系。17周龄时,父系的绒重、毛绒重分别比母系高71.4%和35.8%,含水率、含脂率明显低于母系。第一次活体羽的适宜时间为13或14周龄。本文还就羽绒生长性状间的相关性进行了分析。

Abstract: The growth and physical and chemical claracters of down of male and female lines of Tianfu meat geese were studied from 9 to 17 weeks of age. The results indicated that downbearing performance of the male strain was more than that of the femal strain. At 17 weeks of age, down weight, plumage plus down weight of the male were increased by 71.4% and 35.3% over the female line. The percentage of water or fat was respectively less than that of the female. The time of the first dress plumage was at 13 or 14 weeks of age. Correlation coeff-iciency about some down growth traits was analysed too.
