New Internal Teat Sealant Added to Boehringer Ingelheim Dairy Mastitis Portfolio

Producers now have a choice when it comes to internal teat sealants for their dairy cows

For the first time, dairy producers have a choice in internal teat sealants, and new Lockout™ comes with advantages, like a more ergonomic syringe design and a visible blue paste for easy identification during the removal process.

Boehringer Ingelheim (BI), the second largest animal health business in the world, added LOCKOUT internal teat sealant to its mastitis portfolio earlier this year. LOCKOUT is a non-antibiotic paste that creates an immediate physical barrier against mastitis-causing bacteria at the time of dry-off or in pre-fresh dairy heifers.

The creators of LOCKOUT incorporated features and improvements based on input from producers.

  • It’s the first non-antibiotic teat sealant to have a visible blue paste that’s easy to distinguish from milk during removal.
  • The ergonomic design, exclusively owned by BI, maximizes efficiency while minimizing hand discomfort with the syringe’s larger thumb pad, widened wings and compact size.
  • Application is fast, easy and hygienic. LOCKOUT comes in single-dose syringes with an easy-to-remove cap, and a short tip designed to reduce the risk of introducing new bacteria during insertion.
  • The quick-plunge advantage allows for quick and comfortable administration with a significantly shorter, half-inch plunger stroke to deliver a full 4-gram dose without air bubbles.

“The blue paste is a powerful differentiator,” said Dr. Linda Tikofsky, senior associate director of professional veterinary services at BI. “Because it’s easier to distinguish the sealant from milk, producers no longer have to worry about unnecessarily sending a cow to the hospital pen.”

Twenty-five percent of quarters remain open one week after dry-off, creating an opportunity for infection to occur.1 LOCKOUT simulates a cow’s natural first line of defense, the keratin plug, to seal the teat against harmful bacteria by providing a sterile, antibiotic-free barrier between the udder and its environment.

BI continues to stay at the forefront of innovation and provide producers with the right tools for disease prevention. LOCKOUT joins ToMORROW® (cephapirin benzathine) and Dry-Clox® (cloxacillin benzathine) as part of the BI dry cow mastitis portfolio.
