The publication shows results of studying the influence of new space-planning and technological solutions of easy-to-assemble cattle sheds on the keeping conditions and productivity of intact young bulls of Holstein dairy breed fattening. It is defined that the microclimate characteristics indices in the sheds do not go beyond acceptable norms. Inside and outside temperature differed by 1-1.5 %. Zonal location of animals in sheds allowed ensuring their leisure time period to 13.43 hours per day. Dynamics of average growth gain remained at a sufficient level for the period of 6 months prior to slaughter and was 0.986 g/d. Keywords: ethological indices, productivity and physiological state of animals zonal location, microclimate |
