Abstract/OtherAbstract:
|
Possible regulators of intramuscular fat deposition were investigated in longissimus muscle (LM) and adipose tissues of 18months old Holstein and Charolais bulls. The mRNA abundance of perilipin and transcription factors C/EBPalpha and C/EBPbeta was analyzed by real-time RT-PCR. Carcass traits and marbling traits were recorded and relationships among adipogenic genes and tissue traits were determined. Charolais cattle were heavier (P<0.001) and had less body fat (P<0.001). Holstein bulls accumulated more fat in the LM (P=0.02), but the number and size of marbling flecks did not differ (P>0.7) between breeds. Perilipin, C/EBPalpha, and C/EBPbeta mRNA abundance was influenced by tissue but not by breed. Relationships between mRNA abundance and marbling traits could not be confirmed, however relationships among adipogenic genes. The transcriptional activity of adipogenic genes in LM suggests that intramuscular adipose tissue is still developing and differentiation still occurs. |
