An evaluation of fructooligosaccharide in diets for broiler chickens and effects on salmonellae contamination of carcasses.
Two similar trials were conducted to evaluate the effects of dietary inclusion of fructooligosaccharide (FOS) on live performance and carcass characteristics of broilers and on incidence and level of salmonellae on prechill broiler carcasses. The FOS was fed at two levels (0 and .375%) in a complete factorial arrangement with two levels (0 and 55 mg/kg) of bacitracin methylene disalicylate (BMD) in nutritionally complete diets. Broilers were grown to 49 days of age, and samples were processed to determine dressing percentage, abdominal fat content, and most probable number salmonellae on prechill carcasses. The addition of FOS to nutritionally complete broiler diets at .375% had little consistent effect on growth rate, feed utilization, mortality, carcass dressing percentage, abdominal fat content, or incidence or severity of salmonellae contamination of processed broiler carcasses. There appeared to be an antagonism between FOS and BMD on both live performance and salmonellae contamination of processed broiler carcasses.
