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 ( ) 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 a...

Description
Summary:We hypothesized that supplementing finishing diets with palm oil would promote adipogenic gene expression but depress stearoyl-CoA desaturase ( ) 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 (
