Carcass and Meat Characteristics and Gene Expression in Intramuscular Adipose Tissue of Korean Native Cattle Fed Finishing Diets Supplemented with 5% Palm Oil
We hypothesized that supplementing finishing diets with palm oil would promote adipogenic gene expression but depress stearoyl-CoA desaturase (SCD) gene expression in intramuscular (i.m.) adipose tissues of Hanwoo steers during fattening period (from 16 to 32 mon of age). Fourteen Hanwoo steers were...

description | We hypothesized that supplementing finishing diets with palm oil would promote adipogenic gene expression but depress stearoyl-CoA desaturase (SCD) gene expression in intramuscular (i.m.) adipose tissues of Hanwoo steers during fattening period (from 16 to 32 mon of age). Fourteen Hanwoo steers were allotted randomly to 2 groups of 7 steers based on initial BW and fed either a basal diet (control) or the basal diet supplemented with 5% palm oil (BDSP). At slaughter, i.m. adipose tissue was harvested for analysis of adipogenic gene expression and fatty acid composition. There were no differences in BW or average daily gain between treatment groups. Supplemental palm oil had no effect on carcass quality traits (carcass weight, backfat thickness, loin muscle area, or marbling scores) or meat color values. Palm oil increased (p<0.05) expression of AMP-activated protein kinase-α and peroxisome proliferator-activated receptor-γ, but decreased (p<0.05) CAAT/enhancer binding protein-β gene expression and tended to decrease stearoyl-CoA desaturase gene expression in i.m. adipose tissue. Palm oil increased total i.m. polyunsaturated fatty acids (p<0.05) compared to the control i.m. adipose tissue, but had no effect on saturated or monounsaturated fatty acids. Although there were significant effects of supplemental palm oil on i.m. adipose tissue gene expression, the absence of negative effects on carcass and meat characteristics indicates that palm oil could be a suitable dietary supplement for the production of Hanwoo beef cattle. |
