Therapeutic Effect of a Sodium Salt Mixture Against Salmonella gallinarum Infection in Broiler

The objectives in the present study were to evaluate the therapeutic effect of a sodium salts mixture against Salmonella gallinarum infection in broiler. Of this study, sixty broilers at two weeks of age (body weight, $450{\pm}35$ g) were used to estimate the efficacy of a sodium salts mixture (3.25 mg sodium azide, 2.45 mg sodium cyanide, 0.8 g sodium chlorate) against Salmonella gallinarum infection in broiler with drinking water. Broilers challenged with S. gallinarum were administered with ${\times}$ 1(group I) and ${\times}$ 2(group II) sodium salt mixture for seven days, and cecal content samples were collected at the gate of treatment and on 1st, 3rd, 5th, and 7th day after administration. Changes in body weight and cecal shedding of S. gallinarum were monitored during the experimental period. All groups treated with the sodium salt mixture slightly increased body weight compared to control group but there is no significant difference. At 7th day after administration, the number of S. gallinarum in group I and II was significantly decreased compared to control group (p < 0.001). In the hematological and blood biochemical analysis, values of parameters were not significantly different between the treated groups and control group. From results of the present study, the sodium salt mixture had therapeutic effect on S. gallinarum infection in broilers.
