The correlations between polymorphism of growth horm- one re-ceptor gene and butcher traits in rabbit
兔GHR基因单核苷酸多态性及其与屠宰性状的相关性

Abstract: Five rabbit populations (Belgian hare, Tianfu black rabbit, Great line of Zika rabbit, Harbin white rabbit, and Cali-fornia rabbit) were used to analyze the polymorphism of growth hormone receptor (GHR) gene by PCR-SSCP. Results indi-cated that there were two mutation sites (C705T and C810T) in the 5 populations. The least square analyses showed that the live weight, visceraste weight, and slaughter percentage of AA and MM genotypes were significantly lower than BB and NN genotypes (P<0.05). In contrast, the GHR polymorphism had no significant difference for least squares means of feed trans-formation efficiency (P>0.05). It suggested that GHR gene may be a candidate gene responsible for butcher trait in rabbit.
