| Abstract: | 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. |
