THE INFLUENCE OF COMBINED COMPLEX OF NUTRIENTS ON BIOCHEMICAL PARAMETERS OF BLOOD OF CALVES WITH RICHITIS

The objectives of the study were to investigate the effect of a feed additive based on natural minerals and organic protein on bio-chemical blood parameters in calves with clinical manifestations of rickets. At the beginning of the experiment, changes in the mus-culoskeletal system characteristic of rickets were revealed in the experimental calves. Biochemical blood analysis revealed negative deviations in the parameters of mineral and protein metabolism. The use of a mineral-protein supplement led to the restoration of the concentration of total calcium and inorganic phosphorus in the blood of sick calves and normalization of the ratio between these two elements. Within the reference limits, an increase in the parameters of protein metabolism in the blood was noted, as well as a decrease in the activity of alkaline phosphatase to optimal values. At the external level, the positive effect of the complex remedy was confirmed by ultrasound osteometry, indicating an increase in bone mineral density. An increase in the daily increments of sick calves was also noted. The correct selection of essential nutrients in the complex therapy of rickets of young cattle plays a key role in restoring key characteristics of mineral metabolism and normalization of functions of the entire animal body systems. Provided that the body of calves receives a sufficient amount of naturally necessary components of protein and mineral substances, it is able to effectively perform all necessary functional tasks, including the formation of full-fledged tissue structures.
