The Milk ecosystem comprises a defined sequence of activities that convert raw agricultural output into finished dairy products and deliver them to consumers. Upstream, dairy farms supply raw milk, which is collected and transported to processing facilities. Midstream, processors apply pasteurization, homogenization, and formulation, often supported by equipment manufacturers and technology firms. Downstream, finished products move through distribution networks, retail channels, and food‑service operators before reaching end‑users. Value is generated through quality preservation, product differentiation, and logistics efficiency, while capture occurs at processing margins, branding, and retail pricing.
