大型肉鸭皮脂、腹脂与屠宰性状的遗传变异分析

ANALYSIS ON GENETIC VARIATION OF SUBCUTANEOUS FAT PLUS SKIN, ABDOMINAL FAT AND DRESSED CHARACTERS IN MEAT DUCK

本研究以天府肉鸭GM、GLL、樱桃谷肉鸭CV和狄高肉鸭TC四个商品代肉鸭作材料，分析了肉鸭皮脂、腹脂与屠宰性状的遗传变异．结果表明，在7周龄时，四个组的皮脂重、皮脂率分别为：585．0克、27．01％，553．4克、29．26％，598．0克、28．41％和652．0克、31．89％。皮脂率的变异系数分别为11．33％、6．94％、10．63％和11．60％。母鸭的皮脂率、腹胀率高于公鸭。

Genetic variations of suhcutaneous fat plus skin (SFPS) , abdominalfat (AF) and dressed characters were studied with four commercial meat duckstrains-Tianfu GM, GL, Cterry Vally (CV) and Tegal (TC). The results showed thatat 7 weeks of age, SFPS weight, the perceutage of SFPS of four gronps were 585g,27. 01%, 553. 4g, 29. 26%, 598g, 28. 41%and 652g, 31. 89%. Coefficient of variationof the percentage of SFPS was 11. 33%, 6. 94%, 10. 63%. and 1. 60%. The percentage ofSFPS, AF of females were more than males.
