Mineral additives on the basis of domestic natural minerals, products of chemical and microbiological production are developed. At calculation of structure of additives the daily requirement of animals for mineral substances taking into account a direction of productivity, biological and physiological features of an animal in structure of the experimental mineral additive No. 1 includes forage salt, monoammonium phosphate, brusite, chalk and salts of microcells -100 g of this additive allows to provide completely an animal with microcells, and also to compensate lack of phosphorus, calcium, sodium and magnesium. Mineral additive No. 2 in the amount of 300 g provides the animal's need for trace elements. In addition, this additive includes a daily rate of feed salt and 60% of calcium, phosphorus and magnesium requirements. Therefore, the use of this additive makes it possible to almost fully meet the needs of animals in feed salt, macro- and microelements. Feeding experimental mineral additives to animals allowed increasing milk production during the break-up period by 3.9 and 6.6%, respectively. Balanced mineral nutrition reduced the duration of the service period by 10.2 and 15.8% in the pilot groups. The use of new mineral additives in the diet led to a decrease in production costs by 2.65 and 3.94%. In the end, all this led to an increase in the profitability of milk production: in the control group it was 21.02%, and in the experimental group it was by 3.79% and 5.85% more, respectively. Thus, thanks to the use of new types of mineral additives, animal productivity has increased, feed consumption per unit of production has decreased, milk quality has improved and profitability of production has increased.
