This study was conducted to evaluate the effect of chemical blend additives (a combination of ferrous sulfate and aluminum chloride) on decreasing pathogens in poultry litter. A total of 240 broiler chickens were assigned to 4 chemical treatments with 4 replicates of 15 chickens per pen. The four chemical blend additives were a control (no treatment), 25 g ferrous sulfate + 75 g aluminum chloride/kg poultry litter, 50 g ferrous sulfate + 100 g aluminum chloride/kg poultry litter and 100 g ferrous sulfate + 150 aluminum chloride/kg poultry litter. During the 6-wk experimental period, there were significant differences in both E.coli and Salmonella enterica for weeks 4 through 6, but not at weeks 1 and 3, respectively. Consequently, using chemical blend additives that serve as methods to control strict environmental regulations reduced pathogens in poultry litter.
