Rusko N. Substantiation of a system for monitoring and managing the quality and safety of cows milk

The dissertation substantiates the theoretical, methodological and applied principles of construction and functioning of the monitoring and management system for the quality and safety of cow's milk, which is based on rational methodical techniques of current management models. The first stage of the work reveals the peculiarities of forming the quality indicators of raw milk against the background of the influence of certain paratypic and genotypic factors. It has been established that the studied indicators are significantly influenced by the season of the year, methods of housing and milking cows, their paternal origin and lineage. On the basis of the results obtained, a computer database of milk quali-ty was created, which includes about 74 thousand indicators of chemical composition, nu-tritional value, naturalness and somatic cell content. As part of the second stage, a compre-hensive procedure for monitoring milk quality at various types of farms was developed. The third stage was the logical conclusion of all the research conducted and was based on the substantiation of modern methods for assessing the system of monitoring, certification and standardisation of raw milk quality and safety and its implementation in production. The most significant results of the work performed are three National Standards of Ukraine that regulate the rules for determining the quality and safety of cow's milk, for the first time a standard sample of raw milk was created, and the basic levels of fat and protein mass fractions were substantiated, which were approved at the level of the Ministry of Agrarian Policy and Food of Ukraine to form a pricing procedure depending on its quality. The implementation of the developed monitoring system in production conditions made it possible to improve the quality of milk in terms of somatic cell content and the amount of MAFAnM by 225.3 thousand/cm3 or 46.1 % and KMAFAnM by 1.4 × 105, to obtain an additional amount of profit from its sale in the amount of 1540.3 thousand UAH or 24.0% more compared to the results obtained before the implementation, and ensured an increase in the level of profitability of production and sales by 2.8%. Keywords: monitoring, quality and safety of milk, season of the year, methods of housing and milking, power of influence, database, methods of certification and standardi-sation, economic efficiency.
