The transition cow
Close-up through early fresh: intake lags milk, calcium must adapt, the uterus involutes, and space is part of the protocol.

Field notes on this focus
- Note 01Dry period is recovery timeA controlled dry period plus close-up bunk access is mammary recovery time — not an empty parking lot before calving.Knowledge level in this topic: Intermediate. Barn-side working knowledge in this topic: checks, pairing, and what to do next.3 min · 2026-09-09
- Note 02Amino Acids in the Transition WindowAround calving, a cow eats less just as her udder, liver and immune system pull hard on amino acids. In trials, extra methionine from about three weeks before calving has mostly raised milk protein afterward, while the health benefits are less certain.Knowledge level in this topic: Advanced. Mechanism and stacked risk in this topic — assumes the first-pass frame.3 min · 2026-09-26

- Note 01When the fresh cow’s energy gap widensAfter calving, milk demand rises faster than intake — the gap is where ketone risk lives.Knowledge level in this topic: Intermediate. Barn-side working knowledge in this topic: checks, pairing, and what to do next.3 min · 2026-09-09
- Note 02The DCAD sweet spotPrepartum DCAD is a calcium-readiness tool — moderate negative targets help; extremes buy little calcium and more acid load.Knowledge level in this topic: Advanced. Mechanism and stacked risk in this topic — assumes the first-pass frame.3 min · 2026-09-09
- Note 03Intake before the next additiveTransition-cow intake is the first ration to protect: a heating TMR lowers the nutrients she can actually consume.Knowledge level in this topic: Basic. First-pass in this topic — useful even if you already know another area well.3 min · 2026-09-07
- Note 04The fresh pen was stocked at 120%Calving went well; in the fresh pen, 96 cows competed for 80 headlocks, and first-lactation cows paid in lost bunk access and intake.Knowledge level in this topic: Intermediate. Barn-side working knowledge in this topic: checks, pairing, and what to do next.4 min · 2026-09-07
