Asadi N, Husseini SD, Tohidian MT, Abdali N, Mimandipoure A., Effect of Mentha piperita L. supplement on growth of Ross broilers, Onl J Vet Res., 26 (2):153-157, 2022. We report effects of peppermint (Mentha piperita L.) powder supplement on performance in Ross broiler chicks. Groups of 100 chicks each were given ISO-caloric and nitrogenous diets with 1.5, 3, 4.5 or 6 g/kg of peppermint powder. Controls were fed basal diet without supplement. At starter, grower and finishing periods, average daily weight gain (DWG), feed conversion ratio (FCR) and mortality were recorded. Compared with controls, the supplement boosted (P < 0.05) weight gain and FCR ~10% only during growing period. We found reduced (P < 0.05) mortality and liver weight (~12-14%) in birds given the supplement.
