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.
