Milk as a major commodity derived from animal production is the input of the processing industry, from which a number of products form a substantial part of the population's diet. Milk and dairy products are part of a food chain terminated by consumers for which the price is a criterion of availability. The paper studies the agri- food supply chain of milk production. Paper examine development of the farm-gate, retail and consumer prices of milk and dairy products in the time horizon 2006-2016. Paper examines through a regression and correlation analysis the dependence between the prices of all three stages of the supply chain and determines whether the price-dependence of the production, retailer and consumer prices are statistically significant. If dependence will be confirmed, paper quantifies these dependencies more accurately.
