Feed Mill — definition
Industrial facility that grinds, mixes and processes raw agricultural ingredients into formulated compound feed for livestock, poultry or aquaculture species, typically finished through a pelleting line.
Feed mill processes generally include raw material receiving and storage, grinding, batching and mixing according to a nutritional formulation, pelleting or extrusion, cooling and packaging or bulk loadout. Formulation accuracy and cross-contamination control, particularly for medicated feed, are central quality requirements.
Why it matters to industrial buyers
Feed cost and quality are typically the largest variable cost in livestock, poultry and aquaculture production, making feed mill efficiency and formulation accuracy a direct driver of downstream farm profitability.
Key reference points
Typical stages
Receiving, grinding, batching and mixing, pelleting or extrusion, cooling and bagging or bulk loadout.
Contamination control
Sequencing and flushing procedures are commonly used to prevent cross-contamination between medicated and non-medicated feed batches.
Commonly confused with
Pelleting line
A pelleting line is one processing stage within a feed mill; the feed mill encompasses the full formulation-to-dispatch process.
How it is used in practice
The feasibility study sized the feed mill's grinding and pelleting capacity to match the projected growth of the aquaculture and poultry operations it would supply.
Frequently asked questions
Does every feed mill include pelleting?
Most compound feed mills include pelleting, though some products are supplied as mash or extruded feed depending on species requirements.
How is feed formulation determined?
Nutritionists develop formulations based on species, life stage and ingredient cost, which the mill's batching system then executes.

Pelleting Line
Processing sequence within a feed mill that compresses conditioned mash into dense pellets using a pellet press, followed by cooling, screening and, where required, coating.
Poultry Processing Plant
Facility that converts live poultry into dressed carcasses, cuts or further-processed products through slaughter, evisceration, chilling, cutting and packaging stages under regulated hygiene conditions.
Recirculating Aquaculture System (RAS)
Land-based fish farming system that filters and reuses the majority of its water through mechanical, biological and often disinfection stages, minimising freshwater intake compared with flow-through systems.

Hatchery Systems
Equipment and facility systems used to incubate eggs and rear early-stage animals, such as poultry chicks or fish fry, under controlled temperature, humidity and, in aquaculture, water quality conditions.
