Feeding pigs aged from 61 to 90 days was carried out in bulk, a complete feed for pigs live weight of 20-40 kg, wherein the sodium chloride concentration rate was reduced 9-5 g of Calcium – from 10 to 8.5 g and phosphorus – from 8 to 6.5 g. It was determined that in order to provide increased rates of concentration of sodium chloride, calcium and phosphorus in 1 kg of complete feed for pigs live weight of 20-40 kg is necessary to enter 5 g of sodium salt, 14 g of lime food and 14 g of calcium phosphate, or in an amount of 3.3% by weight, whereas the use of complete feed,according to DSTU 4124-2002 administration of sodium salt of 9 grams, lime feed – 15 g, Mono-calcium – 20 g or in an amount of 4.4% by weight. It was found that when using the complete feed for live pig’s weight of 20–40 kg, with a reduced rate of the concentration of sodium chloride, calcium and phosphorus in the organization of piglets aged 61 to 90 days reduces supply buffer tank It leads to an increase in body weight gain consumption index. On the 60th days of age the live weight of  pigs is 19 kg and  from 61st to 90th days it increased up to 36.5 kg, at the  average daily gain – 585 g and feed conversion of 2.4 kg  per 1 kg of pigs gain, while using  complete feed according to SSTU 4124-2002 these indices  are  18.5 kg, 35.5 kg, 570 g and 2.5 kg respectively.
