【 摘 要 】

The presence of Salmonella species in feeds and ingredients is an important source of salmonella contamination for animals. Organic acid mixtures have shown to be an effective alternative to eliminate salmonellas in feeds and chickens. In the present study, the performance of male broiler chickens receiving levels (0, 0.25, 0.50, 1.0 and 2.0%) of a mixture of organic acids (OAs) (70% formic acid and 30% propionic acid) in the diet was evaluated from the age one to 42 days, in a completely randomized experimental design with five treatments and five replications of 40 birds each. Diets were based on corn, soybean meal and soybean oil. Body weight, weight gain and feed intake from the age one to 21 days were affected by the treatments; 2% OAs in the diet reduced body weight and weight gain. Feed intake increased with concentrations of 0.25 and 0.5% and was reduced with 2% of OAs. From the age one to 42 days, only feed intake was affected, showing a quadratic effect, increasing at the levels of 0.25 and 0.5% and decreasing at 2% of OAs. The mixture of OAs at doses which are effective for the control of salmonella did not affect chicken performance, and the inclusion of 1% OAs in the diet resulted in a performance similar to that of untreated birds.
