¹Three 1,000 pig grow -finish facilities, located on the same production site in Iowa, were each populated with 936 crossbred pigs (Cambrough female [PIC 1050] × DNA600 terminal sire); this study did not start until approximately 34 d post weaning (13.1 ± 0.2 kg of BW). Pigs remained on test until achieving marketing BW (130.5 ± 1.4 kg).

²Least square means of HC.

³Least square means of sex.

⁴Probability values for main effects of HC or sex.

⁵Average start body weight used as a covariate.
