^aScored by 7 panelists according to a 9-ladder whole number scale such that a greater score indicates a better quality in all traits
^bFed the medium-plane phase 1 (P1) and phase 2 (P2) finisher diets (Table 1) during P1 and P2, respectively
^cFed the low-plane P2 finisher diet (Table 1) during both P1 and P2
^b,cData are means of 6 animals
