Functional biologically active feed additive for breeding stock of fish

Abstract

The work is devoted to the development and evaluation of the complex effect of a biologically active feed additive that meets the requirements of a functional feeding complex that ensures the regulation of physiological processes in the body of female breeding stock. In particular, influence of feed additives and its components on growth rate, quality of sexual products, reproductive process, embryogenesis, level of anomalies in the development of offspring, its growth potential was studied. The biologically active feed additive for the breeding stock included probiotic «Sporotermin», adaptogen «Trekrezan», vitamin-amino acid complex «Chiktonik». The hypothesis was tested that the developed feed additive, due to the peculiarities of its composition, is able to increase the growth rate of fish, optimize gametogenesis, reduce the level of pathology during embryonic development, increase the yield of larvae, increase their viability, reduce the level of developmental anomalies, increase survival and safety. The research results showed that the biologically active feed additive reduced the time of fish rearing, had a positive effect on the quality of female eggs and sperm in males, increased the quality characteristics of eggs, reduced the level of embryonic death during embryo incubation, increased the yield of larvae and their safety.
