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。
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 meatyield 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.
