In the given work are outlined the materials on improving the methods of increasing the full value and the assimilability of the produced mixed feed through the use of probiotics and sorbents separately and in the complex. Experimental data proved, that the complex enrichment of rations of sows with probiotic PriMix-Forsil at a dose of 0,5 kg / t and sorbent Vitacorm Reo at a dose of 4,0 kg / t of mixed feed contributes to obtaining the average daily gain in the first period of fattening 581g, in the second period 640 g, at feed expenditure 3.,4 of feed units, an increase of the total protein content in the blood serum by 1,80%, providing an increase of the protein content in meat from 17.76 to 19.78%, the water / protein ratio at 3,93 level and to the economic effect in the calculation for per head on a period of experience in the amount of 70 lei 54 bani. The conducted studies allow to justify a number of proposals for improving the resistance of the organism, safety and productivity of pigs by using in the mixed feed additives of new generation.
