Extract

From birth to weaning calves tolerate most stress include metabolic stress and parturition and at new environment obtained nutrients from milk instead of mother blood. In order to successful production of calves, a set of nutritional and environmental management is needed. Calves mortality from birth to weaning is too much and cost effective for dairy industry. Instead, there is low mortality of heifers from weaning to parturition (1). Brown Swiss breed has low population in respect to Holstein in Iran. Low data is available about Brown Swiss population especially Brown Swiss calves. This study conducted to determine some information about Brown Swiss calves from birth to weaning and factors affecting economic traits at this period.
