2.1. Sample Collection

We focused on the farms having more than 500 pigs and selected five farms where the owners agreed to sampling (Farms A and E in Lusaka, Farm B in Chilanga, Farm C in Kafue, and Farm D in Chibombo District) and samples were collected with local veterinary personnel during the period from January through December 2018 (Table 1). For the collection of fecal samples, some pens were chosen at random, and fresh stools on the floor were collected into tubes. Fecal samples were collected from suckling (0 to 3 weeks old) and fattening pigs (4 to 12 weeks old) with or without diarrhea.
