Effect of sodium bisulfite application on the bed of broiler on survival of Escherichia coli and coliforms

The effect of sodium bisulfate has been evaluated on survival of Escherichia coli and coliforms, when applied on the broiler beds, adopting different densities. It has been adopted densities of 12, 16 and 20 birds/m super(2), using inoculations of E. coli strains. The results have shown the highest microbial development on the 21 super(st) day of inoculation, with a trend of a microbial reduction afterwards. The sodium bisulfate was efficient during the first days of analyses, reducing its efficacy during the experiment.
