摘要: 本研究用27只公羊的后裔122只育成母羊估测了血清总蛋白、清蛋白和球蛋白含量的遗传力分别为0.343、0.555和0.211。这三种血清蛋白含量和育成体重的表型相关分别达到了显著或极显著水平(P<0.05或P<0.01),清蛋白含量和育成体重的遗传相关为0.350(P<0.01)。这提示血清清蛋白含量可作为一个指示性状,用于预测和选种。

Abstract: By analysing serum protein contents of 122 hoggets from 27 bucks, the heritabilities of serum total protein, albumin and globulin were 0.343, 0.555 and 0.211, respectively. The phenotypic crrelations between each of the protein contents and body weight were all significant(P<0.05 or P<0.01). The genetic correlation between albumin content and body weight, with the smallest standard error, was 0.350(P<0.01). It was abvisable that albumin content should be considered as an index trait for sheep breeding.

Key words: SEMIFINE-WOOL SHEEP, SERUM PROTEIN CONTENT, ECONOMIC TRAIT, HERITABILITY, CORRELATION
