Biogenic Akwa-Biot-Norm Feed Additive in Realization of Bioresource Potential of Sturgeon Fishes

Abstract

Research work on an assessment of efficiency of biogenic Akwa-Biot-Norm feed additive developed by scientists is carried out. It is established that application to Lena sturgeon of biogenic feed additive on the basis of a polysaccharide complex of barmy cages Saccharomyces cerevisiae stimulated growth and development of fishes, promoted reliable increase in concentration of hemoglobin, both due to increase in quantity of erythrocytes, and due to increase of their functional activity that demonstrates activization of a gemopoez, increase in intensity of oxidationreduction processes and metabolism in general. Increase in absolute quantity of leukocytes, with the expressed increase in a share of lymphocytes and decrease in relative quantity of neutrophils, basophiles and eosinophils within physiological norms is revealed. These changes of leukocyte profile of Lena sturgeon testify to high extent of development of a cellular link of immunity. The amount of the general protein has increased in serum of blood of Lena sturgeon, which demonstrates activization of synthetic processes in organism of sturgeons and, as a result, increase the intensity of their growth. Significantly increased the value of such indicators of nonspecific resistance of organism of fishes as bactericidal activity of serum of blood for 4,0 %, phagocytic activity of neutrophils – for 5,5 % and concentration of proteolytic enzyme of lysozyme – for 142,9 % that demonstrates activization of cellular and humoral links of nonspecific resistance of an organism. The conducted researches are confirmed by efficiency of application of biogenic Akwa-Biot-Norm feed additive for stimulation of growth and prevention of incidence of fishes due to activization of nonspecific resistance of an organism in the conditions of ecological and technological pressure.
