Social management in feedlots significantly affects cattle welfare, with pen composition, mixing frequency, and group stability all influencing stress levels and injury rates in beef production.
Feedlot cattle endure frequent social disruption through pen resorting and mixing during health management procedures. Each remixing event triggers agonistic behavior as dominance hierarchies are re-established, causing injuries and elevated stress. Maintaining stable social groups through the feeding period, using electronic identification to reunite separated animals, and designing sorting procedures to minimize mixing events are practical welfare improvements that also reduce productivity losses from social stress.
