摘要: 测定了皖西白鹅×四川白鹅F1群体123只鹅的33个胴体性状和7个羽绒性状,采用因子分析方法从中提取出12个公共因子,可解释原40个性状82.24%的信息。研究表明,鹅产肉性能由产肉力、净膛率和腿肉率3个因子组成,可解释原40个性状的36.53%的信息量;肉质特性由脂肪酸品质、产脂力和肌肉水损失3个公共因子组成,可解释原40个性状的18.34%的信息量;羽绒特性由产毛力、绒品质和绒亲水性3个公共因子组成,可解释原40个性状的15.75%的信息量;辅助性能由羽型、心功能和消化力3个公共因子组成,可解释原40个性状的11.61%的信息量。

Abstract: 33 carcass traits and 7 feather-down traits of 123 Wanxi White goose×Sichuan White goose have been mensurated. By factor analysis, 12 common factors were distilled, which could explain 82.24% of the variance of 40 traits. The results showed that meat power factor, eviscerated yield percentage factor, and leg muscle percentage factor of 12 common factors indicated meat-yield capability which could explain 36.53% of the variance; fatty acid quality factor, fat power factor, and meat water loss factor structured meat quality explaining 18.34% of the variance; feather and down characteristic was composed of feather and down power factor, down quality factor, and down hydrophilicity factor explaining 15.75% of the variance; and feather type factor, heart function factor, and digestion factor made up of assistant ability explaining 11.61% of the variance.
