| 摘 要： | 为了分析金湖乌凤鸡体重与体尺的相关性,选取120日龄公母鸡各100羽进行测定和分析,结果表明:公鸡的体重、体斜长、龙骨长、胸宽、胸深、胫长、胫围指标极显著大于母鸡(P<0.01),公鸡的胸角极显著小于母鸡(P<0.01)。公鸡的体重、胸宽、胸深及母鸡体重、胸宽变异系数均大于10%,体尺其他性状指标均小于10%。公鸡体重与体斜长、龙骨长、胸宽、胫围呈极显著正相关性(P<0.01),与胸深呈显著正相关(P<0.05),其中与胫围的相关性最高(0.676);母鸡体重与体斜长、龙骨长、胸宽、胸深、胫长胫围呈极显著正相关(P<0.01),与胸角呈显著相关(P<0.05),其中与体斜长的相关性最高(0.761)。建立最优回归方程,公鸡体重=-1.229+0.392胫围+0.091龙骨长;母鸡体重=-2.377+0.114体斜长+0.224胫围+0.077龙骨长。

| Abstract: | In order to analyze the correlation between body weight and body size of Jinhu Wufeng chickens,the body weight and body size of 100~120 days old male and female chickens were measured and analyzed.The results show that the body weight,oblique length,keel length,chest width,chest depth,tibia length and tibia circumference of cock were significantly higher than those of hens(P<0.01),The chest angles of cocks were significantly smaller than those of hens(P<0.01).The coefficient of variation(CV)of body weight,chest width and chest depth of cocks and those of hens were greater than 10%.Other indexes of body size were less than 10%.There was a significant positive correlation between body weight and body length,keel length,chest width and tibial circumference(P<0.01).There was a significant positive correlation with chest depth(P<0.05).The correlation with tibial circumference was the highest(0.676).There was a significant positive correlation between body weight and oblique length,keel length,chest width,chest depth,tibia length and tibia circumference(P<0.01).It was significantly correlated with chest angle(P<0.05).Among them,the correlation with body length was the highest(0.761).Establish the optimal regression equation,cock:Body weight=-1.229+0.392 tibial circumference+0.091 keel length,hen:Body weight=-2.377+0.114 oblique length+0.224 tibial circumference+0.077 keel length. |
