Pig Welfare: Liquid Feeding Systems

Liquid feeding systems deliver wet feed to pigs, with welfare implications related to competition, feeding behaviour, and system design.

Key Facts

Liquid feeding systems mix feed ingredients with water, potentially improving digestibility and feed intake
Long trough liquid feeding allows simultaneous access for all pigs, reducing competition compared to point feeders
Electronic liquid feeding systems can deliver individualised portions and monitor feeding behaviour
Liquid feeding hygiene management is critical to prevent feed fermentation and associated health problems

Welfare Considerations

Liquid feeding systems can improve welfare by reducing competition at feeding, particularly in group housing. However, system design and hygiene management determine whether the welfare benefit is realised. Well-designed liquid feeding with long troughs and appropriate hygiene represents a welfare-positive approach.

What You Can Do

Support pork producers demonstrating appropriate liquid feeding system design
Advocate for feeding competition to be assessed in pig welfare audits
Engage with research on liquid feeding system design for optimal welfare outcomes
