Effect of BioPlus YC probiotic on production performance and meat quality of pigs

The aim of the study was to determine the effect of probiotic bacteria Bacillus licheniformis DSM 5749 and Bacillus subtilis DSM 5750 on fattening results, share of confiscations, slaughter value of carcass and technological and sensory quality of longissimus lumborum muscle of fatteners. Fattening pigs from the experimental group, since 78 days of age till fattening complete, were supplied with BioPlus YC probiotic (Chr. Hansen) in the amount of 400 g/t. Studies have shown that supplementation with the BioPlus YC probiotic containing specific B. subtilis and B. licheniformis strains had a positive effect on the production results of pigs mainly by reducing the fattening mortality and smaller share of confiscations on the slaughter line of Meat Processing Plants. The effect of using the BioPlus YC probiotic on the carcass meatiness and its components, i.e. ham, loin, shoulder and belly, has not been observed. In addition, supplementation with specific Bacillus probiotic bacteria did not affect the physiochemical properties of the longissimus lumborum muscle and its sensory indicators and shear force.
