Microbial Drug Resistance (2007)
A convenience sample of 20 herds was enrolled with the as-sistance of eight swine veterinarians in Saskatchewan (13 herds)and Alberta (7 herds). Herds were selected by the veterinariansand met the inclusion criteria of having more than 100 sowsand participation in the Canadian Quality Assurance(CQA)Program. Study herds were visited once between May and September of 2004to collect fecal samples, antimicrobial use data, and informa-tion on animal inventory and production practices.
A random numbers table was used to identify 20 pens ofclinically healthy grow-finish pigs in each herd. Freshly voidedfeces were collected from 5 pigs in each of these pens, andpooled to create a pen sample. Each herd owner or manager used existing records to com-plete surveys on antimicrobial use through feed and water. Datafor each exposure of suckling, nursery, grow-finish pig, or sowsin the previous 12 months included the product used, numberof pigs exposed, and duration of exposure.
