The goal of research was estimation of effectiveness of dietary preparations: humine-mineral Humokarbowit (HKW) and humuse-mineral-oil Humobentofet (HBF) applied in pigs feeding. The experimental material consisted of 72 fattened pigs, divided into 3 feeding group (24 animal in each) fattened from 26-29 to about 100 kg of live weight. In the all mash feeds for experimental groups applied HKW preparation in amount 5 percent (group II) and HBF preparation in amount 10 percent (group III). During / Throughout the fattening period the body mass gain and feed utilization /consumption were controlled. After slaughter the estimation of carcass meatiness with use of ultrasonic apparatus was made. The hematologic tests of blood as well as the composition of fatty acids of backfat were determined. The application of humine preparations reduced of bacterium and fungi numbers in mixtures/ all mash feeds. The fatteners fed with all mash feed with addition of HBF had higher body mass gains by 14.5 percent or with HKW by 6.2 percent, in comparison to control animals (group I), at a time in experimental groups the lowest feed consumption/intake was observed. The iron contents in estimated preparations was partially utilized by fatteners what was confirm by hematologic indices of blood. The applied preparations had significant influence on increase of carcass musculature/meatiness and had no influence on composition of fatty acids of backfat
