¹AN = Angus-sired steers selected for a combination of growth and marbling potential, WA-GD = Fukutsuru-sired Wagyu cattle selected for growth potential, WA-MD = Yasufuku-sired Wagyu cattle selected for marbling potential.

²The reported standard error of the mean is the greatest between the different treatments.

^a,bTreatment lsmean estimates within a row, with a different superscript differ (P ≤ 0.05).
