Records feel like admin until the day they save you a cow, a court case, or a milk cheque. The goal isn't to write everything down — it's to capture the few things that change a decision later. Here's the short list that earns its keep.
1. Every treatment — drug, dose, date, and withdrawal period This is the non-negotiable one. If you give a cow antibiotics, you must know exactly when her milk and meat are safe to sell again. Selling milk inside the withdrawal period can fail residue tests, get your whole tank rejected, and in many markets it's illegal. Log: cow, drug, dose, date given, route, and the withdrawal date for milk and meat.
2. Every health event — what, when, and the outcome Mastitis cases (which quarter, which cow), fevers, lameness, metritis, retained placentas, ketosis. One event tells you little; a year of events tells you everything — *which* cows are repeat offenders (cull candidates), *which* diseases cluster *when* (a management problem to fix), and whether a change you made actually worked.
3. Vaccinations and routine procedures — with due dates What was given, when, and when the next is due. Lapsed vaccination is how a preventable outbreak gets in. Hoof trimming, deworming, and tick treatment belong here too.
4. Reproductive events — heats seen, services (with sire), pregnancy checks, calvings. These let you forecast calving dates, dry-off dates, and spot cows that aren't getting pregnant.
5. Key dates per cow — date of birth, calving dates. Almost every other calculation (age at first calving, days in milk, lactation number, when to dry off) hangs off these.
Why "good enough" records beat perfect intentions The best record system is the one you'll actually use every day. A cow with no health history is a cow you're managing blind — you can't see her patterns, can't prove she's clean for sale, and can't tell a new problem from an old one. Even simple, consistent logging compounds into something powerful over a year.
What good records unlock - Safe milk sales (no residue failures) - Cull decisions based on evidence, not gut feel - Early pattern-spotting (the disease that keeps coming back) - Faster vet visits — your vet diagnoses better with a history in front of them - Compliance and traceability for processors and regulators
In Vache, the more complete your health history, the smarter the platform gets at flagging gaps and surfacing the right guidance at the right moment. Records are the fuel for everything else.
