    The purpose of the research is to study the effect of feeding flax seed cake on scar digestion, digestibility and nutrient use to young cattle. The influence of different levels of introduction of flax seed cake into compound feeds for young cattle of the post-dairy period on the digestibility and use of nutrients in diets has been studied. The optimal introduction of flax seed cake with the complete replacement of sunflower meal into mixed feeds for calves was established - 20 and 25% by weight, expressed in the activation of the intensity of physiological and biochemical processes in the rumen, increasing the digestibility of the dry matter of the rations by 1.7 and 1.1 percentage points, crude protein – by 0.5 percentage points, fiber – by 4.3 and 6.9 percentage points, fat – by 6.1 and 15.6 percentage points; improved nitrogen use – by 1.7 and 2.7 percentage points. Studies have confirmed the high nutritional value of flaxseed cake due to the high content of oil, its fatty acid composition, protein, fiber and vitamins.

    The aim of the work is to study the effect of feeding organic chromium on the physiological state, metabolism and productivity of young cattle. Studies have found that the use of organic chromium in feed as part of compound feed has a positive effect on the physiological state of young cattle, leads to an increase in the content of volatile fatty acids in the scar fluid by 1.8-6.0%, a decrease in acidity by 0.9- 4.1% and ammonia by 3.9–8.0%, an increase in the number of red blood cells in the blood by 2.8-6.7%, hemoglobin by 3.3-6.4, urea by 1.4-4.3, calcium by 2.6-4.8 and phosphorus by 6.9-8.8%. glucose – by 5.4%, which provides an increase in the average daily increase in live weight of animals by 2.7-5.4%, while reducing the cost of obtaining feed by 2.2-3.9%. The use of organic chromium is an effective way to increase the productivity of young cattle.
