朗德鹅体尺与体重的相关性研究

Study on Correlation of Landes Geese Body Size and Weight

朗德鹅是产肉、产肝性能好的品种,试验实测结果:朗德鹅体重4.12 kg、体斜长27.44 cm、胸骨长8.38 cm、胸围54.63 cm、胸宽17.94 cm、胫长13.34 cm;本试验采用相关系数法用r检验进行统计分析,试验结果表明:体尺与体重都呈极显著正相关(P<0.01),其中胸围与体重的相关系数最大,达0.637 6,而在各体尺之间亦有较强的正相关,都达到了显著程度(P<0.01)。体重和体尺、胸围和体重是较显著的表型正相关;说明胸围大小是影响朗德鹅产肉性能的最主要因素。

Landes goose is a variety to produce flesh,good product liver.The reality test results are as follows：landes goose weight are 4.12 kg,body length grows 27.44 cm,the breastbone grows 8.38 cm,chest measurement are 54.63 cm,chests are broad 17.94 cm,shins grow 13.34 cm.The statistic analysis was tested adopt relevance modulus law.The results indicated that the body ruler and weight all assumed a pole notable rectify relevance（P0.01）,chest measurement and the weight relevance modulus maximum amount to 0.6376,but stronger rectifying existed between individual ruler relevance,which reached notable degree（P0.01）.Weight and the body ruler and chest measurement and weight were more notable phenotype,which showed chest measurement size was the mainest factor affecting flesh function.
