Effect of Antibiotics and Vitamin-Mineral Supplements on the Saccharomyces Cerevisia Strains of Feed Additives for Poultry and Cattle

The effect of antibiotics and vitamin-mineral supplements on Saccharomyces cerevisiae strains CNCM I-1077 (feed additive Lewisel SC Titan Plus for cattle, horses, goats, and sheep) and CNCM I-1079 (feed additive Lewisel SB Titan Plus for poultry, pigs) studied. The yeast contained in the feed additive sown on nutrient medium No. 2 (Saburo agar) with the addition of chloramphenicol. The number of yeast colonies grown with the addition of antibiotics Enroflon, Florfenicol, Intecol, Klindaspectin, Komplicid, Kvinocyclinum, Macradox 200, Pulmokit, Soladoxy 500, Solamox, Spelink-44, Spelink-660, Sulteprim, Tilmipul, Tilmozin and vitamin-mineral complexes Ciprogen, Floram, Lybecrim, Productive Acid, Productive Forte, Rumisol was recorded VitAmMin. The control happened medium without the addition of veterinary drugs. Veterinary drug solutions added to the nutrient medium at concentrations recommended by the manufacturer for use. It found that the number of colonies of S. cerevisiae in the Petri dishes did not change Klindaspectin, Soladoxy 500, Solamox, Spelink-44, Sulteprim, Tilmipul and the acidifier Komplicid; Florfenicol and Kvinocyclinum increased the number of yeast colonies by 14%, and Tilmipul and Lybecrim by 27%.
