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.
