Yield summary
Cow 42 at 118 days in milk: 27.4 L against a herd average of 24.1 L at similar stage. A 12% drop over three days is flagged for a closer look.
How the Dairy Yield Tracker works
- Record yield per animal with days in milk, since a raw litre figure means nothing without lactation stage.
- Compare each animal against the herd at the same stage rather than against the herd overall.
- Investigate sudden drops promptly — a sharp fall over a few days is a health signal long before it is a yield problem.
The method
Yield follows a lactation curve: rising to a peak within the first two months, then declining gradually until dry-off.
comparisons only mean something between animals at similar days in milk
A cow at 30 days and one at 250 days are not comparable on raw yield, which is why days in milk is recorded alongside every figure.
FAQ
Why record days in milk?
Because yield changes predictably through lactation. Comparing a freshly calved animal with one near dry-off tells you about lactation stage, not about the animals.
What does a sudden drop mean?
It is one of the earliest signals of mastitis, lameness, a feed or water problem, or heat stress. A gradual decline is normal; a sharp fall over days is worth investigating the same week.
Is this a herd management system?
No. It is a record-keeping surface for yield. Full herd management covers breeding, health treatments, and regulatory records, and needs proper software.

Dairy Yield Tracker records days in milk with every figure, because yield compared across lactation stages tells you nothing about the animals.
