Abstract
采用大群和抽样测定方法对保种群2 800只巨型玫瑰冠鸡的冠型性状的基因型、生物学特性、生长性能、屠宰品质、肉品质、繁殖性能等进行了统计与分析.结果表明,玫瑰冠鸡按羽色培育的4个品系群具有耐粗饲、抗寒耐暑、抗病力强等生物学特点;20周龄公、母平均体重分别为1 794~2 284 g和1 463~1 887 g;成年公、母鸡体重分别为2 157.8~2 723.1 g和1 807.2~2 267.3 g,肌肉粗蛋白含量分别为25.64%~26.49%和25.83%~26.47%,肌内脂肪含量分别为4.18%~5.83%和4.38%~5.41%;66周龄产蛋量为203~228个,料蛋比为2.13~2.76∶1;表现出优良地方种鸡的种质特性.
