Mutation rate at exon of GH in five bovine species was very low with the percentage of 3.48%. The majority of nucleotide substitution was nonsense mutation and only one missense mutation was observed. Molecule tree based on haplotypes of bGH at exon 5 showed that differentiation was apparent relatively between Bubalus bubalis and Bos taurus, Bos indicus, Bos grunniens, Bos frontalis. There was no apparent differentiation among other four bovine species and they shared mutual ancestral sequence.

序列分析表明，5个牛种GH基因外显子5的遗传变异水平较低，平均核苷酸变异率约为3.48%，而且绝大多数位点的核苷酸替换是同义突变，仅发现1个错义突变位点；从GH基因外显子5序列单倍型构建的分子进化树来看，水牛与普通牛、瘤牛、牦牛及大额牛的分化相对比较明显，其他4个牛种之间并无明显分化，还享有共同的祖先序列。
