Veterinary Microbiology (2007)
Approximately 10-12 pigs were grouped together in a single pen (space of 2.4 ft^2/pig at nursery and 7.4 ft^2/pig at finishing) under the intensively reared antimicrobial-free (ABF) production system. Under the extensive system, the pigs were reared in a barricaded area that was uncovered. These farms contained 40-50 pigs on an average.
Fecal samples were collected from five intensiveand extensive finishing farms each over a period of 2years from 2002 to 2004. Individual fecal samples(approximately 10 g) were collected per pig withgloved hands directly from the rectum and analyzed.Fecal samples were collected within 48 h of slaughter.

| ABF Rearing Practice | Swine | Grower-finisher | Farm | Here, ABF (antibiotic-free) is defined as no exposure post-weaning. Under the extensive ABF system, pigs have free access to the environment and are placed in barricaded fields - pigs in the intensive system are placed in confined barns with concrete slat | 12 |
