Metabolism in the body and productivity of calves when feeding corn grains

The results obtained during an industrial inspection to establish the dependence of the productivity and physiological state of calves on feeding whole and crushed grain, which ensures the cultivation of healthy animals with high body resistance, confirmed the previously made conclusions about the possibility of effective use of whole and crushed corn grains in the diets of calves as part of compound feeds in a ratio of 70:30%. It was found that growing young animals on KR-2 compound feeds with the inclusion of whole and crushed grains in experimental compound feeds allowed for an average daily increase in live weight of calves at the level of 810-860 g. Calves that consumed whole grain corn in the amount of 30% of the weight of compound feed (group II) – 860 g, which is higher by 6.2% relative to the control group. The inclusion of crushed corn grains in the compound feed for calves of the III experimental group contributed to an increase in the average daily increase by 4.2%. It was determined that the introduction of whole grain corn in the amount of 30% by weight into the compound feed for calves aged 66-115 days contributed to an increase in its nutritional value by 5.2%, energy value by 5.6% to the control value, crushed – 3.5 and 2.9%. As a result of the research, it was determined that the blood saturation with the respiratory pigment hemoglobin in experimental young animals of groups II and III was higher than the control analogues by 5.7 and 4.6%, which indicates an increased metabolic rate. In the blood of animals of the II and III experimental groups, an increase in the total protein content was noted by 3.5 and 1.8%, relative to the control value.
