Outline of Final Research Achievements |
This study was to analyze the free fatty acid receptors、IGFs and IGFBP in rumen papillae, to select Japanese Black cattle with high quality, based on the genetic polymorphism of growth hormone. (1) Free fatty acid receptor 4 were significantly higher in rumen papillae of weaned cattle compared with sucking cattle. (2) IGF-1 was not different between rumen papillae of suckling and weaned cattle. IGFBP2, 3 and 6 were significantly lower in weaned cattle, however, IGFBP5 was significantly higher in weaned cattle.
