摘  要:
用建昌鸭86只进行了体性状与肝重相关关系研究。结果表明,所测建昌鸭的十一个体性状中,体重与肝重的相关关系最为密切,其次是胸骨长。用体重和胸骨长作自变量,肝重作依变量建立了二元回归方程。以所测体性状为自变量,以肝重为依变量建立了二次完全式曲面方程。本文还对早期体性状与后期的肝重的相关关系进行了研究。

摘  要:
Eighty six Jianchang ducks (JD) were used to study the relationships of body weight and body meaurements to liver weight. Among the 11 measured traits in JD, body weight is of closest relationship with liver weight, and keel bone length, of the second. Prediction equations for liver weight with body weight and keel bone length as independent variants are presented. Those for liver weight, which are set up by using stepwise regression of quadric surface, with all the measured traits as the independent variants and the liver weight as the dependent variant, are also presented. The relationships of the early body weight and body meaurements to the later liver weight are given in the paper.
