Effect of Feeding with Organic Microelement Complex on Blood Composition and Beef Production of Young Cattle

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% (P<0.05), glucose - by 4.7-6.3% (P<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.
