The aim of the trial was to study the effectiveness of the utilization of the sorbent Praymiks Alfasorb additives and to determine the optimal level of the introduction of these additives into the mixed feed for young pigs. The studies were conducted at the State Enterprise “Moldsuinhibrid” from 6th of February, 2011 to 6th of April, 2011. A scientific and economic experiment was held using four groups of breeding pigs, selected on the basis of pair analogues of the same breed, live weight and age. It was ascertained that the feed additive Praymiks Alfasorb had a positive effect on the energy of animal growth and their productivity, the young pigs’ average daily weight gain increased on average by 6.65-7.90 %, and the feed consumption per unit of output fell by 5.11-16.61%. It was determined that the optimal level of the introduction of the sorbent Praymiх-Alfasorb into the mixed feed for growing piglets was 0.2 kg/t.
