ВЫВОДЫ Анализируя полученные данные можно констатировать, что дробное скармливание жвачным животным силоса отдельно от концентратов, вследствие меньшего снижения кислотности в рубце, оказывает менее негативное влияние на развитие и жизнедеятельность рубцовой микрофлоры по сравнению с однократной дачей этого корма. <...> По результатам исследований получен патент на изобретение (№2506925). <...> SUMMURY The article presents data on studying of a pulpy fodder (silage) feeding technology influence on a rumen digestion course of bull-calves which is expressed in change of hydrogen ions (рН) concentration. <...> The results of researches showed that the rumen fluid рН mean of experimental animals was unequal and varied depending on different scheme of forage feeding. <...> The optimal feeding technique of the sour fodder with positive effect on the conditions during the process of digestion is defined. <...> The single joint feeding of silage and concentrates in daily quantity for bull-calves leads to the greatest and the longest decrease in rumen acidity, whereas the rumen contents pH mean decreases considerably less and for a shorter time after feeding with increase in frequency rate of silage feeding and giving it separately from the concentrated forages. <...> It was found that the fractional feeding of silage for ruminant separately from concentrates has a less negative impact on development and activity of rumen microflora in comparison with a single feeding of this feed due to the smaller decrease acidity in the rumen. <...> This is also confirmed by the higher volatile fatty acids concentrations in the rumen of experimental bull-calves. <...> The use of double silage feeding separately from concentrates promotes higher activity of microorganisms <...>
