Abstract: Polymorphism of the growth hormone receptor (GHR) in improved hybrid beef cattle group from Liupan Mountain area in Ningxia province was investigated to give the rationale for hybrid improvement. Polymerase chain reaction-restriction fragment length polymorphisms (PCR-RFLP) technology was carried out to examine polymorphisms of GHR gene of 70 individuals. PCR products of 338 bp digested by restriction enzyme Alu Ⅰ showed polymorphisms.There were two genotypes of AA and AB. The frequency of A allele was higher than B allele, and the frequency of AA genotype was higher than AB genotype.

Key words: beef cattle; growth hormone receptor gene; polymorphism
