摘要
此研究旨在对育雏期河北柴鸡和海兰灰蛋鸡(每品种公母各50只)的体重体尺性能进行测定,并对测定的指标进行相关性分析.结果表明:各周龄海兰灰蛋鸡生长速度明显高于河北柴鸡,差异均显著(P< 0.05)或极显著(P< 0.01);两个品种体斜长及胫长与体重存在中度(P<0.05)或高度(P< 0.01)相关,河北柴鸡4周龄时体斜长和胫长与体重的相关系数分别为0.712和0.647,海兰灰蛋鸡3周龄时体斜长和胫长与体重相关系数最高,分别为0.845和0.883.
Body weight and size of Hebei local chicken and Hyland hen at brooding period were measured.The results showed that growth rate of Hyland hens was faster than Hebei local chicken, with significant difference( P <0.05) or highly significant difference ( P <0.01). Middle or high corelationships were found between body length, shank length and body weight in the two varieties. At 4 weeks, higher correlation coefficient on body length and shank length with body weight was observed, being respectively 0.712 and 0.647 in Hebei local chicken. At 3 week age the highest correlation coefficient on the two indexes reached 0.845 and 0.883 respectively for Hyland hens.
