摘　　要：本试验对贵妇鸡早期生长发育等有关指标进行观测，以揭示该鸡种质特点及性状相关。并应用多元回归分析方法探讨体斜长、胸角、胸骨长、主翼羽长、尾羽长、胫长和胫围对体重的相关，结果表明，公鸡早期生长速度较母鸡快，平均日增重比母鸡高0．93g，公母鸡6周龄体重分别为375．03g和336．77g；累计耗料量公鸡比母鸡多124．56g；公母鸡料肉比分别为3．50和3．54；6周龄公母鸡羽毛长齐，主翼羽分别长达11．72cm和11．64cm。经相关分析表明：公母鸡的胫骨长和体重呈强正相关，而公母鸡的胸围和母鸡的胸骨长分别与体重呈正相关；经6周龄饲养公母鸡成活率均达100％，抗逆性强，是值得推广的优质鸡种。In this experiment, the concerning indices of growth and development at the early stages of Guihu fowl varieti were tested to find its characters of germ plasm and trait correlatiou, and multiple regression analysis was used to detect the correlation between body shape data and body weight. The results indicated that at the early stages the growth rate of a cock was higher than a hen and its average daily gain was 0. 93g higher than a hen. The body weights of a cock and a hen at the age of 6 weeks were 375. 03g and 336. 77g, respectively. The total feed consumption of a cock was 124. 56g higher than a hen. The feed conversion rates of a cock and a hen were 3. 50 and 3. 54, respectively. At the age of 6 weeks, the feathers of a cock and a hen were completely grown up and the feather lengths of the main wings were 11. 72 cm and 11. 64 cm, respectively. According to the correlative analysis, there was a high positive correlation between feet lengths and body weights, and between breast surrounds and body weights. After being fed for 6 weeks the fowls had a viability of 100% with high tolerance and proved to be an excellent variety for extension.
