Three-times-daily milking increases milk yield but may affect dairy cow welfare through altered rest and feed patterns. Understanding the trade-offs matters for welfare-conscious dairy.
Milking frequency affects dairy cow welfare through its impact on rest time and udder discomfort. Three-times-daily milking that reduces lying time below welfare thresholds causes chronic fatigue and stress. However, engorged udders between milkings also cause discomfort — higher frequency milking may reduce this particular welfare problem. Automated voluntary milking systems, where cows choose when to be milked, offer an interesting welfare-positive approach, though access competition can create social stress. The overall welfare picture depends on how milking frequency interacts with other farm management decisions.
