俄语. Включение в состав комбикорма КР-1 телятам экструдированного пищевого концентрата в количестве 15 % по массе способствует активизации микробиологических процессов в рубце, оказывает положительное влияние на окислительно-восстановительные процессы в организме животных, а также позволяет повысить среднесуточные приросты телят на 8 %, снизить затраты кормов на 9 % и получить дополнительную прибыль на 10 % больше контрольного варианта.

Balanced compound feeds suppose including of various expensive ingredients, such as extraction cake made of sunflower and soybean. Linseed cake appears a good substitution of import compounds, possessing rich chemical composition. The main goal of the research presented in the article appears evaluation of the efficiency of feeding of KR-1 compound feed with different norms of input in calves’ rations. Inclusion of 15 % of extruded food concentrate into KR-1 feed for calves contributes to the enhancement of microbiological processes in the rumen. It is reflected in the increase of the concentration of volatile fatty acids by 14.5 %, decrease of pH by 4.7 % and ammonia by 10%. It ensures the increase of digestibility of dry and organic matter by 9,7-65 percentage points, crude protein by 6.8 percentage points, fiber by 4.5 percentage points, fat by 5.2 percentage points, the concentration of total protein in serum by 7,5%, and the decrease of urea content by 16.2 %, allowing to increase the average daily gain of calves by 8%, to reduce the cost of feed by 9% and get more profit by 10 %.
