Продуктивные качества и развитие потомства при формировании групп коров позднего сухостоя

Experiment was conducted on milk farm (700 dairy cows). The experimental animals for 20 days before the expected calving moved to a separate section, with simultaneous changes in the composition of feed mixture: increased concentration of energy and nutrients in the diet. Isolation of technology group of pre calving cows favorably impacted the passage of calvings, physiological state during the transition period, the chemical composition of colostrum and dynamics of weight gain of calves as well as economic efficiency.
