[Objective] The paper aims to study the relationship between genetic polymorphisms of three gene loci and growth character of Haimen Goats to provide reference to promote Haimen Goat growth character and cultivate Haimen Goat new strain of fast-growth. [Method] We processed analysis and related statistical analysis on three gene loci of Haimen Goats with PCR-RFLP and PCR-SSCP. [Result] The results suggested that there were two genotypes in MSTN gene IntronⅡ, GH gene exonⅠ and GH gene exonⅡ in Haimen Goats. Different genotypes of these gene loci had different effects on relative growth character of Haimen Goats. [Conclusion] This study had a significant meaning about promoting Haimen Goat avoirdupois by marker assistant option.
