AHV-StopLac-EU-1000x667-GREY

StopLac

Facilitates abrupt dry-off by reducing milk production.

AHV StopLac Tablet is designed to support dairy cows during dry-off by temporarily adjusting rumen fermentation. This approach reduces milk production, resulting in less udder engorgement, milk leakage, and bacterial contamination—key risk factors for infection.

By easing udder pressure and minimising stress, StopLac promotes better cow welfare while ensuring a smooth, healthy transition into the dry period. This not only protects udder health during the entire transition period but also helps set the cow up for a successful next lactation.

“The Cows Cease Production Almost Instantly” – Jon Beller On Using StopLac

Farmers about StopLac

“The cows that received StopLac had no loss of milk. They felt better, it also preserves the animal’s well-being during dry-off.”
GAEC Du CastelFrance
“StopLac helped us to get our cows to the next lactation in healthy condition!”
Martin ZimmerlingGermany
“With StopLac, we were able to optimize dry-off significantly. Daily group changes are no longer necessary and, above all, no cow leaks milk.”
AHV_Deutschland - Neue Wege beim Trockenstellen Erfahrungen mit AHV StopLac HFD
Rita HauschildGermany
“The cows went through the dry period more easily and started milking again quickly as soon as they had calved.”
Jennissen snellere droogstand efficiëntere opstart StopLac
Rob & Jan JennissenNetherlands
“The cows cease production almost instantly, there’s a lot less vocalization, and we do not see any more milk secretion after dry-off.”
Jon Beller
Jon BellerBeller Farms | New York, USA
“You can dry them off abruptly and you don’t have any extra stress for that cow. It doesn’t take any work, which saves money. They start up very calmly, and you can actually see that they produce more milk and remain consistent. Udder health and cell counts are also better.”
