The use of polysaccharide regulatory complex ensures an efficient energy exchange of the animal, resulting in higher milk yields, lower feed costs (and lower methane emissions). These benefits have a direct impact on a farm’s profitability. The study aims to form a methodological approach to assess the effectiveness of frugal innovation (implementing polysaccharide regulatory complex) in dairy cattle breeding. Applying economical innovations on a dairy farm based on polysaccharide regulatory complex use resulted in reduced feeding costs, increased milk yields, improved milk quality, and improved functioning of animals’ immune system. The study provides opportunities to increase the consumption of basic foodstuffs of animal origin based on the effective implementation and management of frugal innovations that involve qualitative changes that can ensure economic competitiveness in national and foreign markets and state food security.
