Litskiy V. Zoohygienic of the requirement to a sophistication of technology cultivation of a joung growth by effecting a beef on small farms

Object of research - calves in their birth and the level of their viability, reconstruction of the working stock-breeding building; the equipping of group cages for constant maintenance of young bulls; back-ward growth young bulls of Ukrainian black-variegated milk breed. Subject of research - the compound parts of microclimate in the buildings for maintenance of bulls of Ukrainian black-variegated milk breed in dependence of system, way and method of their maintenance, employment of free areas for constant maintenance of bulls from one to eighteen months' age. Ways of research - tasks put in this work were decided with the use of hygienic, ethological, stockbreeding, biological, biometrical and economic methods. Theoretical and practical results - on a theoretical and practical plans the work which was fulfilled prove the high economic, effectiveness of the influence of stockbreeding conditions of undeterred ways for maintenance of bulls at the expense of reasonable defectiveness of back ward growth young bulls, increasing of production beef and improving its quality, creation of optimal sanitary-hygienic conditions of microclimate and rational use of the feed energy by young bulls and constant maintenance not tribal young animals of Ukrainian black-variegated milk breed from one to eighteen months' age. Novelty: developed and researched group cages for undeterred keeping of 10 six-month bulls. At the six-month age 20% of defective bulls are taken out that makes possible to keep standardization conditions of maintaining other bulls scale for prognosis of calves' viability was worked out under the tests of their behavior. Veal and beef of defective backward growth bulls of Ukrainian black-variegated milk breed which were undeterred in before killing living weight, weight of fresh carcass, killing weight, but for inner fat, on the contrary, the tethered bulls have superiority. The degree of adoption - "Methodic recommendations on substantiation of reasonable defectiveness of their behaviors when they were born". The received results of stockbreeding hygienic demands for improvement of technology on breeding young animals in producing beef is used in elaboration estimate of expend here for reconstruction of working stockbreeding buildings and in organization of milk cattle breeding at small farms. The results of research are used in working programs "Zoohygienc with the principles of designing and building stockbreeding objects" for students of production technology and conversion stockbreeding products department of Vinnytskyi State Agrarian University. The sphere of usage of this research work is stockbreeding, animal hygiene and veterinary sanitation.
