The fresh pen was stocked at 120%

A 700-cow herd had a clean maternity area but an overcrowded fresh group: 96 cows for 80 headlocks. Older cows displaced first-lactation animals, which ate late or skipped meals. Penn State's transition guidance puts feed intake at the center of metabolic success; Dairyland Initiative guidance emphasizes adequate bunk space and avoiding excessive transition-pen stocking. Reduced intake deepens negative energy balance and raises ketosis risk; low intake and feeding time are also associated with impaired immune function and postpartum uterine disease, but crowding alone does not prove causation.

The herd split a late-fresh group and kept the true fresh pen below capacity. Heifer intake improved within a week. Uterine cases lagged because involution and inflammatory recovery take weeks, not hours. New calvings stopped repeating the same pattern. The practical lesson is simple: fix access to feed and rest before interpreting treatment counts. Disease assessment and treatment remain veterinary decisions. Educational only — not a diagnosis, prescription, or treatment protocol.
