The swine herds were selected on the basis of the level of antimicrobial agents used. Samples were taken from a total of 10 swine herds. The use of antimicrobial agents was considered to be high for two herds (Abhlgh herds), for one herd the use was considered to be medium (Abmedlum herd), and for the remaining seven herds the use of antimicrobial agents was estimated to be low (Ablow herds). The classification of the use of antimicrobial agents was mainly based on the level of exposure to antimicrobial agents during the piglets first 6 weeks of life. Litters in the Abhlgh herds were routinely given antimicrobial agents to cure or prevent infections. The litters in the Abmedlum herd were sometimes given antimicrobials for therapeutic or prophylactic purposes, whereas the litters in the Ablow herds were almost never exposed to antimicrobial agents.

Samples of feces were taken from 12 fattening pigs in each of the 10 herds.
