| Popis: | Modern aquaculture is characterized by new approaches to the fish maintenance in conditions of high stocking density, associated with the restoration of the natural ecology of the body and based on the use of biologically active products. One aspect of this approach is to normalize altered the microbial environment of the organism in water of a recirculating aquaculture system with probiotics. Probiotics have the ability to regulate the microbiocenosis of the digestive tract, making a significant contribution to the absorption of nutrients. The use of probiotics can solve a number of problems related to the physiological state of animals and fish, increasing the efficiency of digestion, stimulating growth and development. Probiotic preparations of the new generation include probiotics “Ferm-KM” and “ProStor”, which are sorbed forms containing bacteria immobilized on solid sorbent particles. The article presents the results of the use of probiotics “Ferm-KM” and “ProStor” in the composition of production compound feeds for sturgeon fish. It was found that the use of new generation probiotic preparations in the diet of sturgeon fish contributes an increasing in the number of beneficial microorganisms in the intestine (up to 8.5x107 CFU/g) of Russian sturgeon. The effectiveness of introducing a new generation of probiotics into the compound feed for sturgeon fish has been proven, which contributes to increasing the resistance of the macroorganism to pathogenic microorganisms, improving the functioning of the digestive system. Probiotic strains introduced with preparations interact with the community of intestinal bacteria, releasing metabolites that affect the digestive, immune and hormonal systems of the body. |
