A trial was held in the Land O’Lakes Research Facility (Wisconsin U.S.A.) to investigate the effects the phytogenic additive Digestarom® Milk (BIOMIN GmbH, Herzogenburg, Austria) on the performance and health of calves when added to a Calf Milk Replacer (CMR) (courtesy of B. L. Miller, T. J. Earleywine and T.E. Johnson, Land O’Lakes Inc.). Digestarom® Milk is a blend of plant extracts (herb, spices, essential oils and non-volatile plant extracts) formulated to increase palatability, digestion and improving zootechnical parameters which help maintain a better intestinal health and a reduction in digestive disturbances, i.e. scours.
