The Next Lactation Starts Here
Higher milk yield through abrupt dry-off
The next lactation begins at dry-off.
By managing dry-off in a controlled and predictable way, both you and your cows are optimally prepared for the upcoming lactation.
Knowing exactly when dry-off takes place and when the next lactation will begin helps reduce stress¹ during this critical phase.
Abrupt dry-off with StopLac:
- Delivers higher milk yield in the subsequent lactation² ³
- Maintains appetite
- No withdrawal period
- A smooth and controlled dry-off process
