However, fi nal BW
(P = 0.19) and carcass weight (P = 0.45) were unaffected
by supplemental dietary oils. Marbling scores tended
(P < 0.09) between palm oil-fed steers (Modest09) and
soybean oil-fed steers (Small55). Neither palm oil nor
soybean oil signifi cantly affected fat thickness, KPH
(both P = 0.15), or yield grade (P = 0.24). Overall maturity
scores were lower (i.e., more youthful; P < 0.01) in palm
oil-fed steers than in control and soybean oil-fed steers
