In the conditions of the Republic of Belarus there was developed a new national original concentrate and new receipts of whole milk substitutes (WMS) with great part of home-made (Belarusian) components. Effectiveness of new WMS utilization in rations of calves is analyzed. Competitiveness of products with high level of fats is evaluated. Content of different types of whole milk substitutes and their realization prices are compared and analyzed. Factual nutritive value of 1 kg of different types of WMS is evaluated. Influence of different types of WMS on productivity indexes of calves is displayed. Impact of different types of whole milk substitutes on hematological indexes of calves' blood is analyzed. Economic efficiency of application of different types of WMS is evaluated. The research shows that the increase of the content of components from biologically valuable domestic raw materials in the composition of experimental types of whole milk substitutes (WMS) ensures the reduction of their price (by 22–27%) in comparison with actually used substitutes (analogues). Unsoldering of calves with cheap experimental types of WMS with highly nutritious extruded concentrate on the basis of flax seeds promotes the increase of daily gain by 14%. As a result, the payback of experimental types of WMS has risen by 1.5 times as compared with the substitutes used actually in Vitebsk oblast ('Vitamilk-P3' and 'Telenok-K23/12').
