Object of research - bull-calves for breeding of Ukrainian black-bright milk breed, indoor maintenance of cattle, small dairy of productivity ways of maintenance: permanent or impermanent, microclimate in door. Subject of research - experimental checking of group cages on 10 bull-calves in age 4-8, 8-12. 12-16 month's in the permanent method of keeping in the conditions of balanced feeding of animals. Ways of research - principle of selecting of bulls-calves analog-group for keeping in different ways in indoor maintenance estimation of the conditions of keeping in the technological period producing beef from bull-calves for breeding; method of searching variants of group cages and experimental selecting one of the variant by the methods of estimation: microclimate, bull-calves behavior, weighting them, slaughtering and economic analysis of received data. Theoretical and practical results - scientifically and enterprises of law productivity of profit-malign can be received from bull-calves of theUkrainian black-bright milk breed in the improved cages on 10 beats. It is obvious to heap the suitable optimal, ecological, ethological, feeding and sanitary conditions of keeping. Novelty: for the first time were conducted researches of three types for group cages equipped with the additions to the norms of technological projecting and have purpose for breeding, before raising and feeding bull-calves. Hygienic-sanitary estimation of air-conditions in group cages for impermanent keeping of bull-calves corresponds to the optimal project-technological regime and for permissible exploitation regime in the 5 and 14 month's day - and - night fluctuate ions. On the actions of bull-calves during 120 minutes after the beginning of conditions of keeping, but under impermanent - chewed forage longer, stayed without actions and moved along the cage. Established principle of forming meat productivity of bull-calves for breeding of the Ukrainian black-bright milk breed, witch depends on the condition: "Methodic recommendations as to the usage of group cages for keeping young growth for breeding in the different technological periods", "Methodic recommendations for rating estimation of microclimate in animal placing for producing beef with permanent and impermanent method of keeping the young growth of the cattle in small farms". The results of researches are used in project-estimate documents and in studding process for preparing technologists for producing and reproducing of the animal production of the Vinnitsa State agrarian University. Sphere of usage - cattle breeding, hygiene of animals and veterinary sanitary.
