A technological line for the production of granulated feed stuff was presented in the work. Three recipes for granular feed stuff for young rabbits (28-135 days old) were developed with the addition of experimental dietary supplements (PGC-92-1 supplements - dry herbal pulp from red clover, alfalfa grass flour and probiotic Sporothermin; PGC-92-2 supplements - protein feed concentrate from stillage filtrate (wheat), alfalfa grass flour and probiotic Sporothermin; PGC-92-3 supplements - green protein complex (PGC) from red clover, alfalfa grass flour and probiotic Sporothermin). Comparative analysis with the control recipe PGC-92 (control) without dietary supplements was carried out. The nutritional value of the feed stuff met the requirements for this group of animals. The storage of the produced feed stuff was carried out in production conditions (floor storage warehouse) in paper bags of 30 kg per group at a temperature of 18 ... 20 ° C and a relative humidity of 65 ... 70%. Due to the moisture content exceeding the requirements of the standard, a higher content of fungal and bacterial microflora was noticed in the feed stuff (control sample). The acid number of the fat and the total acidity increased, which indicates the instability of this batch of feed stuff during storage. Experimental variants of feed stuff had stable quality during storage and were of good quality throughout the test period. A production check of the influence of the studied complexes in young rabbits fattening was carried out in the conditions of the industrial complex of "Lipetsk Rabbit" LLC with a livestock of 2000 rabbits. The used complete granulated feed stuff with the introduction of bio-additives made it possible to increase the slaughter yield by 3.62, 4.45 and 3.96%, while reducing the feed cost per 1 kg of slaughter mass by 0.72, 0.38 and 0.88 ECU. An increase in profit was achieved by 17725.25, 16114.38 and 14168.55 rubles, as well as the level of profitability by 45.93, 41.26 and 31.24%, which is associated with a higher safety and productivity of the raised population of rabbits
