Tied or tethered stall systems that confine dairy cows continuously for extended periods cause significant welfare problems and are being phased out across Europe.
Tied stall systems cause profound welfare compromise through restriction of fundamental movement. Cattle confined in tied stalls cannot groom normally, turn around, or engage in social interactions with other animals. The resulting muscle atrophy, joint problems, and lameness are direct welfare consequences of chronic confinement. Stereotypic behaviours including tongue rolling are more prevalent in tied systems, reflecting unmet motivational needs. Psychological welfare is also impaired by the monotonous, barren environment and inability to perform natural behaviours. The transition from tied to loose housing systems with outdoor access represents a major welfare improvement that is achievable within normal farming investment cycles.
