📍Hypocalcemia (Milk Fever): the postpartum emergency you can’t ignore
At calving, calcium demand spikes fast. If the cow can’t mobilize calcium quickly enough, blood Ca falls → neuromuscular failure, gut stasis, recumbency, bloat risk, and death if untreated.
What you’ll see (field staging)
Stage I: tremors, twitching, “nervous” cow
Stage II: sternal recumbency, cold ears/feet, “S-bend” neck
Stage III: lateral recumbency, coma, severe bloat risk
Treat NOW (clinical milk fever)
✅ Slow IV 40% calcium borogluconate (~400 mL ≈ 12 g Ca)
⚠️ Give slowly + monitor the heart (rapid IV calcium can cause fatal arrhythmias).
Relapse can happen—plan follow-up support and reassess non-responders.

If you’re seeing repeat cases, your transition system needs work:
Close-up mineral strategy (DCAD), adequate Mg, and correct cow condition.
If you haven’t had a clinical milk fever case in 2+ years, your transition program is likely working.
