MILK REDUCTION
StopLac modifies rumen fermentation to temporarily reduce volatile fatty acid production. Trials show this temporarily reduces milk production within 24 hours.

WHY THE DRY-OFF PROGRAM WORKS FOR YOU
Are you tired of burdensome “dry-off days”? Ready to take control of dry-off—naturally?
Drying off can make or break the next lactation for your cows. It’s a process that involves considerable labor and hassle, and during this period, cows are at increased risk of infection —it’s crucial to get it right.
UDDER HEALTH PROTECTION
Less disruption, more resilience.
Take control of your cows’ dry period. By reducing milk leakage, boosting comfort, and strengthening udder immunity, you can protect your herd from harmful pathogens and cut the risk of new udder infections. This means fewer cell count problems, better milk quality, and a healthier start to the next lactation. With the right start of the dry period, you’ll give your cows the recovery they need and set them up for maximum productivity and long-term health.
COW WELFARE REALIZED
Easing pressure means easing suffering.
Drying off cows naturally marks a shift toward more natural and protective practices. By treating orally, you reduce the risk of pressure-induced pain from abrupt milk cessation, easing the cow’s discomfort during this transition.
This approach also lowers the chance of intramammary infections, emphasizing prevention over treatment. It supports a gentler, less disruptive transition for the cow, enhancing her resilience and overall well-being. Most importantly, it aligns with the cow’s natural physiology — trusting her biology to guide the process, as this program is designed to do.
OPERATIONAL EASE
One dose, one touch, one less thing to worry about.
Using a one-step, oral administration method for drying off cows simplifies the entire process, making it more efficient and less stressful for both you and your animals. This streamlined approach lowers the chances of mistakes and the need for re-treatment, reinforcing the idea that simple systems are safer systems. By removing the need for blanket dry-off procedures in the milking parlor, you can reclaim valuable time and space, making dry-off day smoother and more manageable.
Faster drying period and more efficient start-up with StopLac
After a successful collaboration with AHV, Jan and Rob Jennissen decided last year to test StopLac when drying off their cows. This choice quickly proved to be a good move, as the cows dry up faster and the start-up after calving went much more efficiently. “The cows went through the dry period more easily and started milking again quickly as soon as they had calved.”

protocol explanation
4-8 WEEKS BEFORE DRY-OFF
- Extra: The 4–8 weeks before dry-off are a vital window for udder health. Administering the product during this period helps break down biofilm in the udder, reducing bacterial risks and setting the stage for a healthier, more productive next lactation.
- Aspi: When biofilm is broken down and bacteria are released for clearance, the immune system must respond. Aspi Tablet helps modulate this response, preventing the immune system from overreacting.
AT DRY-OFF
- StopLac: Administer within two hours after the final milking to ensure the udder is empty and to maximize product efficacy.
