Production: dosing → grinding in a hammer mill → mixing in a horizontal mixer (3–5 min) → pelleting in a pellet press (temperature 70–85°C) → cooling → sieving → packaging. Pellets: 3 mm (poultry), 5 mm (pigs), 8 mm (cattle). Storage: dry warehouses, temperature ≤25°C, humidity ≤75%. Shelf life 3–6 months.
