| 摘 要： | 本试验采用大型肉鸭C、G、M、L四个品系及其杂种CM、CL、GMGL，狄高肉鸭商品代TC，组成九个组合。在相同舍饲条件下，对生长性状和屠宰性能进行测定。结果表明：天府大型肉鸭父系c优于G，母系M优于L。四个杂交组中以CM最好，6、7周龄体重均居各组之首，料肉比都低于其它三组，胸腿肌率在6、7周龄都高于CL、GM、GL，而皮脂率在6、7、3周龄低于各组．因此，CM是一个比较理想的两系配套组合，可用于大型肉鸭的商品生产。肉鸭单位面积胸肌纤维数与胸肌重呈极显著负相关，与活重、瘦肉率也吴负相关。

| Abstract: | The growth and slaughter chartcters of Tian Fu large-type meatduck strains C, G, M, L and their crosses CM, CL. GM, GL and the commercial meat duckof Tegal (TC) were analysed under the same condition. The results indicated thatCM had the greatest body weight (2785g, 3206g) at the age of 6, 7 weeks and hadthe best feed efficiency in four crosses. CM contained the liglest percentage ofbreast and leg muscle at the age of 6, 7, 8 weeks in the crosses. The number ofbretst muscle fiber at unite was highly correlated negatively with breast muscleweight (r=-0. 522) and correlated negatively with body weight (r=-0. 225) andpercentage of lean (r=-0. 287) respctiyely. |
