Abstract

This study determined the association between Myf5, CAST and MSTN genes and fattening performance traits in 228 (Holstein = 103 and Brown = 125) cattle breeds. Classification and regression tree (CART) was used to determine association between genes and fattening performance. The allele frequencies of Holstein cattle in terms of Myf5, CAST and MSTN genes were A:0.30, B:0.70; A:0.43, G:0.56; A:0.97, B:0.03, respectively, whereas in the Brown Swiss cattle were A:0.36, B:0.64; A:0.65, G:0.34; A:0.88, B:0.12 respectively. The Myf5, CAST, and MSTN genes were found to be in the Hardy–Weinberg equilibrium (p > 0.05) in both of the cattle breeds. As a result, the association between Myf5, CAST and MSTN genes and fattening performance traits were found to be significant according to CART analysis.

Myf5、MSTN和CAST基因多态性与瑞士褐牛和荷斯坦牛育肥性能的相关性

摘要

该研究确定了 228 个(荷斯坦牛 = 103 和布朗 = 125)牛品种的 Myf5、CAST 和 MSTN 基因与育肥性能特征之间的关联。分类和回归树 (CART) 用于确定基因与育肥性能之间的关联。荷斯坦牛Myf5、CAST、MSTN等位基因频率分别为A:0.30、B:0.70;A:0.43, G:0.56; A:0.97,B:0.03,分别,而在布朗瑞士牛中,A:0.36,B:0.64;A:0.65, G:0.34; A:0.88,B:0.12 分别。发现 Myf5、CAST 和 MSTN 基因 在两个牛品种中都处于 Hardy-Weinberg 平衡(p > 0.05)中。结果,根据 CART 分析发现 Myf5、CAST 和 MSTN 基因与育肥性能特征之间的关联是显着的。
