† Control and Low; n = 7 steers per treatment;
‡High; n = 6 steers.
*Standard Error of the mean; standard error pooled across treatments.
**P values are pooled across treatments.
a,b,c superscripts = note significant differences (P = <0.05) between treatment groups.
1 A 9-point hedonic scale was used (1 = Dislike extremely and 9 = like extremely).
