Research and production experiment on studying the efficiency of calve growing depending on the methods of their husbandry at the prophylactic and lactic periods was realized in the conditions of the Republic of Belarus. It was established, that calves which were kept in course of the analyzed periods in group cages of a calf-house at the age of 180 days had live weight on 9 kg (or on 5,4%) higher than cattle kept in course of the prophylactic period in individual cages of a prophylactorium calf house, and at the same time their live weight was on 3 kg higher (or on 1,7%) rearers kept in the same period in group cages on the open air conditions. The average daily live weight gain of cattle was also higher on 7,2 and 1,6%, respectively. However, in the conditions of the group husbandry of growing stock in the calf houses there was stated that the analyzed animals were more often ill, so it could be concluded that the presented animal husbandry method could be used only in favorable epizootic conditions in animal husbandry farms. In the conditions of an open air husbandry the ways of infection diseases incidence was substantially lower, and calves showed high development indices in case of complete feed diets application
