[Method] The GHR mRNA expression levels in longissimus dorsal muscles of male Kazak sheep and Xinjiang fine wool sheep with different ages were quantitatively analyzed by real time PCR. [ Result] Sheep GHR mRNA expression level in longissimus dorsal muscle increased firstly followed by decline, and then kept steady until the end of the experiment, with the expression peak appearing on postnatal day 30. The GHR mRNA expression level of Kazak sheep was extremely lower than that of Xingjiang fine wool sheep from 2 to 90 days old （ P 〈0.01 ）. E Conclusionl Both age and breed had great effects on the expression of muscular GHR gene in sheep.展开更多
