Pig Welfare and Liquid Feeding Systems

Liquid feeding systems can improve pig welfare through reduced aggression at feeding, but require careful management to prevent welfare problems.

Key Facts

Competition for food is a primary driver of aggression in group-housed pigs
Computer-controlled liquid feeding allows individual ration adjustment
Poor liquid feed hygiene leads to fermentation and mycotoxin contamination
Liquid feeding enables high inclusion of food industry co-products, reducing waste
