PHYSIOLOGICAL STATE AND PERFORMANCE OF YOUNG CATTLE AGED 6-9 MONTHS DEPENDING ON GRAIN MECHANICAL PROCESSING METHODS
The paper presents the results of studies on determining correlation of protein use and performance of young cattle with methods of mechanical processing of high protein concentrates. It has been determined that crushing of field pea and vetch grain contributes to 42 and 35 p.p. reduction of protein degradability in rumen. Use of crushed field pea and vetch grain for feeding young cattle contributes to improvement in physiological state of animals, as indicated by increase of red blood cells count, hemoglobin, total protein and phosphorus in blood of experimental animals. Feeding animals with crushed grain ensures increase in average daily weight gain by 4.6-5.4% while reducing the feed cost for obtaining the gain by 2.0-3.3% and increasing the efficiency of dietary protein utilization by 2.2-2.4%.
