摘要
试验对矮小型鸡3种羽色类型的体型性状和产蛋性能进行了研究,比较了各羽色鸡24~43周龄产蛋率、蛋重、体重、蛋品质以及300日龄体尺指标。结果表明,矮小型鸡的体重和体尺指标在3种羽色间差异均不显著（P〉O.05）,产蛋率、蛋重、蛋形指数、蛋壳强度、蛋白高度、哈氏单位差异不显著（P〉0.05）,蛋壳厚度在不同羽色间存在极显著差异（P〈0.01）,研究结果可作为矮小型鸡选育的参考依据。
The traits of body type and laying performances of three dwarf chicken breeds differentiated by plumage color were analyzed and compared. The main traits included laying rate at age between 24 and 43 weeks, egg weight, body weight, egg quality and body measurement index at 300 days age. The results showed that the body weight and body measurements had no significant differences among the three dwarf chicken breeds（P〉0.05）. There were also no significant difference in laying rate, egg weight, egg shape index, eggshell strength, albumen height and Haugh unit（P〉0.05）. However, the eggshell thickness showed extremely significant difference among the three breeds（P〈0.01）. It will provide a reference for the breeding of dwarf chicken.
