a The number of each serogroup was determined in our laboratory by examination of Salmonella isolated from cloacal samples of chicken in Chiayi County and from surveillance of Tainan and Pintung County.
b NHC: 9-wk-old Native Hybrid Chickens (simulated native chicken) of Taiwan broiler chickens
c Chick: one-day-old NHC chicks.
