Access to feed is a fundamental welfare requirement, and feed face design, space allowance, and management directly affect the welfare of group-housed cattle.
Feed access welfare reflects the dominance hierarchy dynamics inherent in group cattle management. Subordinate cows that are displaced from feeding positions consume less, have poorer body condition, and are more vulnerable to metabolic disease. Insufficient feed face space amplifies competitive exclusion. Feed barrier design including tombstone barriers can cause neck injuries and deter cows from reaching feed. TMR systems that are pushed up frequently reduce sorting behavior where cows select energy-dense components. Synchronization of feeding with milking times and social group management can reduce competition effects. The welfare cost of feed access restriction falls disproportionately on lower-ranking animals who are often already in poorer condition.
