How to record colostrum on every calf
A 30-second job on the calf passport. Four fields that, more than any other, predict what kind of life that calf is going to have — and the only honest way to know if your shed's protocol is actually working.
If you've read our essay on colostrum, you already know why this feed matters more than anything else you'll do for a calf in her first year. This guide is the small companion piece: where the field is, how to fill it in, and what Calfmate gives you back once you have.
Where to find it
Colostrum is recorded on the calf passport — not on the calving form. That's deliberate: colostrum usually happens 5 to 60 minutes after the calf is recorded, so the passport is where you go back to. Open the calf (Calves → tap her tag, or follow the link Calfmate offers you straight after recording the calving) and scroll to the Colostrum section.
If she was born in the last hour and hasn't been fed yet, the section shows a golden window countdown at the top — a polite nudge that the clock is ticking.
The four fields
- Fed at. Tap "Now" or use the time picker if you're catching up. Don't backdate-fudge — accuracy matters here.
- Volume — slider, 0 to 10 litres. A full tube-feed is 4 L on a 40 kg calf. A bottle of fresh colostrum is usually around 2 L.
- Quality — Brix %. Only if you actually measured. Tick "Measured?" then enter the Brix (10–35). Skip if you didn't measure — don't guess.
- Source. Pick a chip: Dam (fed) · Suckled · Pooled · Replacer · Frozen/stored.
Tap Record colostrum. Done.
If colostrum is already on file and you need to fix it, the section shows the saved values with an Update colostrum button.
What Calfmate gives you back
Three immediate outputs
- Colostrum tier on the passport — Gold / Silver / Bronze / Missed / Pending — calculated from timing, volume, and Brix.
- Activity timeline entry for the audit trail. (Useful when the vet wants the calf's full history.)
- Reports → Colostrum section — your monthly capture rate, average Brix, and low-Brix count. The one number every dairy farm should know.
Three honest tips
Brix is worth the $40
If you don't have a Brix refractometer in the shed, get one. Without it, every "I think the colostrum was good" is a guess. With one, you've got a number — and the difference between a 22% batch and a 19% batch is sometimes the difference between a thriving heifer and a treated one.
Tube isn't a failure
Bottle feeding is gentler on the gut but you may not hit 4 L in one go. Tube feeding is faster, takes good technique, and works fine when the calf isn't keen. Either is fine — record what actually went in.
"Suckled" should be ticked sparingly
Suckling alone, with no observed feed, is one of the most-studied risk factors for failure of passive transfer. If you didn't see her drink, don't guess that she did.
If she missed the window
If the calf is more than 6–8 hours old and still unfed, finish recording anyway. Then raise a Health check flag for the next feeding round so the next person knows to watch her closely. The records save the next decision.
One thing to take away
Recording colostrum is a 30-second job. It's also the single most predictive data point on the whole passport. If your shed isn't already doing this consistently, this is the field to start with — today.
