DairyTalk 257: The 3.5-Hour Cow Rule: Hidden Losses in Modern Dairy Systems - by Helmut Demmelhuber

Cows operate on a strict daily time budget: resting, eating, and
ruminating require about 21 hours per day. That leaves no more
than 3.5 hours for milking and management. This article explains
how exceeding that limit directly reduces milk yield, milk fat,
and animal health. Overcrowding, long waiting times, and limited
feed space intensify this hidden bottleneck. The key message is
clear: milk production is driven by rest, not technology.
Optimizing cow time budgets is one of the most effective - and
inexpensive - ways to improve dairy performance. With comments on
