Abstract: The association between fat distribution and feed efficiency was investigated using Angus steers divergent in residual feed intake (RFI) estimated breeding values (EBV). The 208 steers were fed in a commercial feedlot in NSW for 250 days, entering at 13 – 16 months of age. Hot standard carcass weight, eye muscle area, marble score, intramuscular fat content, rib fat (subcutaneous) depth and seam (intermuscular) fat area were measured and regressed against the mid-parent RFI EBV of the steers. The results showed that rib fat depth was more strongly associated with RFI EBV than were the other fat depots.
