Abstract. Lambs from birth (0-day-old) to 56-day-old were selected in present study to investigate developmental changes of growth hormone receptor (GHR) and insulin-like growth factor I (IGF-I) mRNA expression in their rumen tissue. Forty-five lambs (5 lambs per group) were slaughtered at 0, 7, 14, 21, 28, 35, 42, 49, 56 days of age respectively for sampling the tissue of the rumen dorsal sac. The abundance of GHR and IGF-I mRNA were detected through real-time quantitative PCR method. The results indicated that the expression levels of GHR and IGF-I mRNA had similar change tendency in rumen tissue that the GHR and IGF-I mRNA abundance decreased with age from birth to 56-day-old. There was significant positive correlation between the two gene mRNA expression levels. The results suggested that GHR and IGF-I gene expression levels had the specific developmental pattern in rumen tissue.
