Abstract

Since the Veterinary Feed Directive became effective in 2015, poultry producers have sought a replacement for antibiotics in commercial broiler diets to promote growth and gut health. A series of poultry feed additives including probiotics, prebiotics, yeast products, etc., have shown some success in improving growth performance of broilers. Two solid state fermentation DFM products from two different lactobacillus strains were fed at two inclusion levels (0.05 and 1%) to study the effects on weight gain, FCR, and ADG, and gut health parameters following feed restriction and FITC-dextran (FITC-d) gavage. Under our research conditions, certain dietary treatments decreased "gut leakage" as measured by FITC-d fluorescence in the serum, but performance paramaters were not significantly affected by dietary treatments.
