| Abstract |
|
The present study was conducted to investigate the preventive effect of feed supplemented with 1.0% oriental herbal medicine feed additives (OHMFA) on the colonization of Salmonella spp. and incidence of death in broiler chickens. The frequency of Salmonella spp. in feces samples treated with OHMFA (25/239; 10.5%) was significantly reduced (p<0.05) than that of control group (83/347; 23.9%). A total of 108 Salmonella spp, belonging to four different serotypes, were isolated from three broiler farms. Among the serotypes isolated, Salmonella typhimurium was the moot prevalent (60.2%), followed by S. enteritidis (20.4%), S. gallinarum (13.0%) and S. pullorum (6.4%). In incidence of death in chickens during experiment, the mortality of rate OHMFA group (3.9%) was significantly lower (p<0.01) than that of control group (5.7%). These results show that the administration of OHMFA may prevent the colonization of Salmonella in chickens. |
