  1. 1Pigs assigned to the good sanitary conditions were housed in cleaned and disinfected rooms and received an antibiotic supplementation; pigs assigned to the poor sanitation conditions were housed in rooms that were not cleaned; the ad libitum group corresponded to pigs nourished ad libitum on overall experimental period; the restricted group corresponded to pigs that received, from 2 to 7 d after weaning, respectively, 20, 30, 40, 60, 80, and 90% of the amounts of feed voluntary consumed by ad libitum pigs in both sanitary conditions at each previous day. No feed restriction × sanitary conditions interactions, (P > 0.10).
