Makarynska A. Scientific and technical basis for improving the technology of compound feed enrichment with biologically active substances

The thesis is devoted to the complex solution of the problem – the scientific substantiation and technological feasibility of the production of homogeneous mixtures for the enrichment of compound feeds with biologically active substances, the expansion of the range of protein-vitamin supplements and premixes, as well as improving their quality by optimizing the formulation and stabilizing the composition, substantiating the technological modes of technological methods for the production of enrichment mixtures and development of structural and logical models for the production of premixes. The classification of biologically active substances and fillers has been improved depending on the properties and features of the technological process for the production of premixes and compound feeds. A classification of generations of premix production has been developed. The technological process of mixing the components of premixes is investigated and the determination of the evaluation of the efficiency of obtaining homogeneous mixtures using the stability coefficient is proposed. The technique for assessing the quality of premixes has been improved. Calculated highly effective recipes for liquid and dry premixes, protein and vitamin supplements for farm animals and poultry, domestic animals by linear optimization. Effective feeding programs have been developed, which can reduce the consumption of feed raw materials, reduce the feeding period and improve the conversion of compound feed. The annual effect of using liquid premix on the basis of Ptitsevod COOO, which includes lacto- and bifidobacteria, is 75.6 thousand UAH, universal complex premix for poultry 3600 thousand UAH. Technological methods for enrichment of compound feeds with biologically active substances, technology for the production of loose and molded premixes based on a complex filler, technology for the production of loose and extruded protein-vitamin supplements have been developed. The main indicators of the quality of premixes and protein-vitamin supplements (BVS) have been studied. A batch technology for the production of molded premixes has been developed, the optimal values of the ratio of the components of the complex filler and the technological modes for obtaining molded premixes based on them by granulation and rounding have been determined. The technical conditions for the technological instruction for the production of BVS for pets were developed and approved. The technology of BVS production for pets has been introduced at Agrotrade-Yug LLC and Dubovenko TM. The annual effect of the production of the Mobican BVS is 37683,2 thousand UAH.
