Effect on Field Trial of Oriental Herbal Medicine Feed Additives on Prevention of Salmonella in Chickens







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 freqency 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 most isolated from three broiler farms. Among the serotypes isolated, Salmonella typhimurium was the most prevalent (60.2%), followed by S. enteritidis (20.4%), S. gallinarum (13.0%) and S. pullorum (6.4%). In incidence of death in chicken during experiment, the mortality of rate OHMFA group (3.9%) was significant lower (p<0.01) than that of control group (5.7%). These results show that the administration of OHNFA may prevent the colonization of Salmonella in chickens.
