Gilts restricted fed a high-protein ration were slower growing (P<.05) than gilts ad libitum fed a high- and moderate-protein diet. Gilts ad libitum fed a moderateprotein diet with added fat had significantly (P<.05) more fat accretion than gilts ad libitum fed and restricted fed a high-protein diet. A genetic line by diet interaction (P<.05) was observed for average daily gain. Also, gilts with the presence of a terminal breed in their ancestry were leaner and heavier muscled (P<.05) than gilts with no presence of a terminal breed in their ancestry.
