Effects of Dietary Supplementation with Organic Acids and Zinc Bacitracin on Ileal Microflora, pH and Performance in Broilers

An experiment was conducted to determine the effects of an organic acid combination (Acid Lac Dry: lactic, fumaric, propionic, citric and formic acid) and/or zinc bacitracin on the body weight gain, feed efficiency, microflora and pH in the ileum content of broiler-type chicks. Ross PM3 broiler chicks were placed in an experimental design that consisted of four dietary treatments with 48 broilers in each group. One-day-old chicks were fed either a control diet or a similar diet supplemented with 3 g/kg Acid Lac Dry, 0.1 g/kg zinc bacitracin or both additives in combination during a 42-d feeding trial. Acid Lac Dry+zinc bacitracin supplemented diet, significantly (P
