Abstract

Trace elements are commonly used in the form of inorganic salts poorly digested by ruminants due rumen microflora, which transits its greater part into indigestible and insoluble form. Trace elements in the form of chelates are supplied with amino acids and peptides, and used by the body much more efficiently. Inclusion of organic trace element complex (OMEK) in compound feed KR–1 in the amount of 10% of the existing standards for trace elements content in typical formulations for growing young cattle for meat has a positive impact on palatability of feeds, morphological and biochemical composition of blood and animals’ performance, economic efficiency of calves fattening. Use of organic trace element complex in compound feeds KR–1 increases concentration of total protein in blood by 8 – 12% (P < 0.05), reduces the amount of urea by 11 – 16% (P < 0.05). Comparative analysis showed that animals in experimental group II used the feeds more efficiently. Metabolizable energy consumption per 1 kg of weight gain made 33.7 MJ against 37.4 MJ in the control group or by 9.9% lower, the same trend is established for digestible protein cost – by 10%. Inclusion of OMEK in compound feed KR–1 for young cattle ensures average daily weight gain increase by 12.3% (P < 0.05), decreased of feed cost per 1 kg of weight gain by 10%. Use of organic trace element complex helps to decrease the cost price of weight gain, by 9.0% and obtain extra profit of $37.2 USD per one animal during the experimental period.

Highlights

Knowledge of the natural amount of trace elements in feeds and diets is a prerequisite for the organization of a balanced nutrition and obtaining high performance of animals (Radchikov et al, 2010; Suchkova et al, 2012; Kairov et al, 2014)
In scientific and economic research the steers of the control group received compound feed KR–1 with premix of standard formulation, milk, milk replacer, hay, silage, rolled corn grain; and young cattle of the II group – KR–1 feed with premix consisting of organic trace element complex in addition to the basic diet
Researches helped to determine that dry matter intake of experimental animals was at a level of 1.71–1.75 kg/day
