Swine liquid feeding kitchen for 6,000 finishers — Denmark
Illustrative scenario: Danish finisher unit installing a full liquid-feed kitchen with load-cell mixing, whey and bakery by-product intake and phase-fed rations, targeting lower feed cost per kg gain and improved gut health via fermented cereal streams.

Load requirements
Design loads used to size housing, utilities and equipment.
Herd feed volume
26 t/day dry-matter equivalent
Ration phases
4 (25–45, 45–70, 70–95, 95–120 kg)
Mix DM target
24–28% DM (pumpable)
By-product streams
Whey (12 t/d) + liquid bakery (4 t/d)
Feed events
6–8/day per valve group
Pipe hygiene cycle
Water flush every event + weekly acid CIP
System design choices
Why each subsystem was specified the way it was.
| Area | Choice | Rationale |
|---|---|---|
| Mixing | 12 m³ agitated tank with load cells + high-shear mixer | Load-cell dosing hits ±1% ingredient accuracy and handles viscous by-products without lumps. |
| By-product intake | Chilled reception silos + inline homogeniser | Whey and bakery streams must be chilled and homogenised to avoid separation and spoilage. |
| Fermentation | 10 t fermentation tank for cereal + lactic culture | 24 h fermentation drops pH to 4.0, reduces enterobacteria and lifts feed intake ~5%. |
| Ration engine | Recipe per barn section, phase-fed by pig age | Cuts crude protein 1.5 pts in late finish — saves cost and reduces nitrogen output. |
| Hygiene | Water flush + weekly organic-acid CIP | Biofilm in feed pipes is the #1 cause of liquid-feeding underperformance — non-negotiable. |

Representative outcomes
- Typical scope: 12 m³ mixing tank + 8 recipe circuit valves
- Typical outcome: feed cost/kg gain −11%
- Typical outcome: FCR 2.55 → 2.42 (30–120 kg)
