Effect of Lactobacillus sp. and yeast supplementation on performance and some blood attributes in deoxynivalenol-challenged broiler chickens

An experiment was conducted to evaluate the effect of different concentrations of probiotic (Lactobacillus sp.) and yeast (Saccharomycese cerevisiae) on performance, organ attributes and blood traits in broiler chickens. A total of 360 one-day-old female broiler chickens (Hubbard)® were allocated to 9 treatments and four replicates (10 birds per replication). The trail was performed in a completely randomized design (3 × 3 factorial arrangement) to examine the interaction effect of three concentrations of Lactobacillus sp. (0, 0.2 and 0.4 g/kg) and yeast (0, 0.75 and 1.5 g/kg) in deoxynivalenol (DON)-contaminated diets. The results showed that consumption of Lactobacillus sp. and yeast in DON-contaminated diets did not have a significant effect on broiler performance except for feed intake during starter period which was enhanced by yeast administration (P
