2、著和極顯著相關性，并確定了相關指標的回歸方程，為通過活體的體尺測量結果預測屠體性能指標提供一定的理論依據(jù)，同時試驗結果表明F代雜交雞的生產(chǎn)性能顯著提高。關鍵詞：雜交雞；體尺；屠宰性能；相關分析中圖分類號：$813．22文獻標識碼：A文章編號：1004—874X(2014)01—0106—04CorrelationanalysisbetweenthebodysizeandslaughterperformanceinF1hybridofspringofprincessl●’1n●1’●’chickenandIrlZZlechickenLINai-bin，YANGFen-xia，DUBi
