| Abstract: | In this paper,a partial sequence of growth hormone releasing hormone gene were T-A cloned by PCR and sequenced on Bos grunniens.The comparison of the fragment sequence with those of Bos taurus and Sus scrofa growth hormone releasing hormone gene through blastn of genebank,the result showed that the homolgies of the nucleotide sequence with Bos taurus are98%and with Sus scrofa 'are89%.7variation sites and1.6%sequence divergence and three types of mutations including transition,transversion,insertion were detected on Bos grunniens,of which transition was the most frequent. |
