Abstract

Analysis of the feeding schemes has shown that higher nutritious diet of the calves raised up to 6 months of age can be provided by increasing the share of mineral substances of organic nature – the organic microelement complex (OMEC). The research studies have found that the OMEC has a positive impact on the feed palatability and beef production. As evidenced by morphological and biochemical composition of blood, the organic microelement complexes intervention into the mixed fodders MF-1, MF-2 and MF-3 activates metabolic processes in the body of the animals, with the total protein concentration accurately to increase by 7.7-7.8% (Р<0.05), glucose – by 4.7-6.3% (Р<0.05), and the urea level to be down by 13.0-14.3%. The tendency of red blood cells, hemoglobin, alkali reserve, calcium, phosphorus, magnesium, iron, zinc, copper to increase by 1.6-10.3% has also been established. The OMEC integration into the composition of the complete fodders MF-1, MF-2 and MF-3 for young cattle increases the average daily gains by 9.5-12.3% (P<0.05) depending on the age, with the feed costs for 1 kg of gain to be cut by 7-10%. The organic microelement complex helps to reduce the gain costs by 7.0-10.9%, depending on the age of the animals. Taking into account positive results of testing the premixes containing the OMEC on young cattle in a production environment, it is recommended to use the supplement studied as a component of a feedstuff in industrial complexes and specialized farms for beef production at the rate of 10% of the existing norms of trace elements in model formulations.
