How long cows have been lactating, viewed as the spread of the herd across stages of lactation. In a year-round herd a steady, even spread is what keeps the vat full month to month.
Aim to hold average days in milk near 160–180 in a year-round herd; a rising figure signals cows not getting back in calf.
Dairy Australia · InCalf ↗Average days in milk drives total vat volume and feed demand. A herd bunched in early lactation is near peak and hungry; a climbing average signals cows failing to get back in calf and dragging production down.
Silo pulls each of these from the sources the operation already uses, and keeps the figure current automatically.
Hold the 100-day in-calf rate so cows re-calve on schedule.
Dry off chronically late, low-yielding cows rather than carrying them.
Use the distribution to plan feed and grouping through the year.
