摘　　要：为比较不同羽色藏鸡育雏期的生长发育情况,试验选取白麻羽、黑麻羽、黄麻羽和红麻羽育雏期藏鸡,进行体重和体尺指标的测定与分析。结果显示:育雏期不同羽色藏鸡的生长趋势无明显差异(P>0.05);红麻组和黄麻组育雏期体重、体尺指标均高于白麻组和黑麻组,且黄麻组和红麻组体斜长显著高于黑麻组(P<0.05),黄麻组髋骨宽显著高于黑麻组(P<0.05);红麻组和黑麻组育雏期体重、体尺指标的相关性较高,且体重与胫长的相关程度均为极显著相关(P<0.01)。结果表明:不同羽色藏鸡育雏期生长速度基本一致;黄麻羽藏鸡和红麻羽藏鸡育雏期指示生产性能指标中体重、体尺发育较好;黑麻羽藏鸡和红麻羽藏鸡体重、体尺指标相关性较高,体型匀称性更好,并且应将胫长作为藏鸡早期选育的重要参考标准。In order to compare the growth and development of different feather color Tibetan chickens during the brooding period,the experiment selected Tibetan chickens with white,black,yellow and red feather during the brooding period for the determination and analysis of body weight and body size trait indexes.The results showed that there was no significant difference in the growth trend of different feather color Tibetan chickens during the brooding period(P>0.05).The indexes of body weight and body size of red group and yellow group were higher than those of white group and black group,and the oblique length of body of the yellow group and red group was significantly higher than that of the black group(P<0.05),and the width of the hip bone of yellow group was significantly higher than that of black group(P<0.05).There was a high correlation between body weight and body size of red group and black group,and the correlation between body weight and tibial length was highly significant(P<0.01).It is concluded that the growth rate of different feather color Tibetan chickens is basically the same during brooding period.The indexes of body weight and body size indicating production performance of yellow-feather and red-feather chickens are well devel-oped during brooding period.Black-feather and red-feather chickens has higher correlation of body weight and body size indexes,better body proportionality,and the tibial length should be used as an important reference standard for the early selection and breeding of Tibetan chickens.
