WHY STOPLAC WORKS FOR YOU

Quickly reduces milk production without the need to reduce feed or alter milking frequency, helping to make dry-off faster and more manageable. By lowering udder pressure, it helps reduce engorgement and milk leakage, supporting udder health and comfort during the transition.

  • Makes dry-off simpler and more efficient
  • Helps reduce udder engorgement and milk leakage, lowering the risk of new intramammary challenges
  • Supports animal comfort and welfare promoting a stronger start to the new lactation
  • Meat and milk withdrawal free – no prescription required

MODE OF ACTION 

AHV StopLac is a complementary feed for cows.

AHV StopLac is a complementary feed designed to support a smooth and controlled dry-off.

By influencing rumen fermentation, StopLac helps to temporarily reduce milk synthesis, allowing milk production to decrease naturally without restricting feed or altering milking routines.

The formulation supports lactose reabsorption and helps maintain a slightly lower udder pH, creating conditions that are less favourable for bacterial growth. This contributes to reduced udder pressure, less leakage, and improved mammary tissue comfort, helping to protect udder health during the dry period and into early lactation.

Preliminary Evaluation of a Phytogenic Dry-Off Tablet on Dairy Cow Transition Health and Performance

  • StopLac showed beneficial effects during dry-off and early postpartum
  • Improved protein-energy metabolism (NEFA, urea), liver function (AST, GLDH), and overall clinical status
  • Reduced metabolic stress during the transition period, supporting udder health regeneration and enhancing resilience to metabolic and infectious challenges at lactation onset
READ FULL PAPER

Field trials in the USA including 2 farms and 404 cows (233 AHV, 171 Control) showed that cows receiving StopLac at dry-off had:

  • 70% difference in milk leakage after dry-off
  • 6.7 lbs difference per day in milk production (100DIM average)
  • 47% difference in death losses (60DIM)

Compared to the control group.
