What is it?

CepraLock® is designed for use at drying-off, with or without a dry cow intramammary antibiotic, and provides an important inert barrier in the teat canal to reduce the risk of a bacterial infection of the udder during the dry period.Cepralock can be purchased in single boxes of 24 tubes (6 cows) and buckets of 144 tubes (36 cows). Both include biodegradable disinfectant wipes for udder preparation.

How does it Work?

Infusion of the product into each udder quarter produces a physical barrier against the entry of bacteria thereby reducing the incidence of new intramammary infections during the dry period. The product is sterile and has no antimicrobial activity.

How to use: MSD Animal Health have launched an udder health video series to raise awareness about the correct procedure when drying-off cows, ahead of the dry cow season.

The video series features well-known veterinary consultant, Tommy Heffernan – better known as Tommy the vet – who shares lots of practical tips, tricks, and advice to help farmers get prepared for a successful dry-cow period

Why use it?

According to Dr. Jantijn Swinkels, DVM, PhD, Ruminants Technical Director Veterinarian at MSD Animal Health “farmers should be using internal teat sealants, with studies showing that nearly 25% of teat ends remain open for as long as six weeks after drying off.
“Adding a teat sealant to a dry cow management program helps prevent infection and supports the responsible use of antibiotics.”
60% of all new infections in early lactation can be traced back to the dry-cow period. Adding a teat sealant to a dry-cow management programme has been proven to reduce mastitis incidences by up to 25% in the next lactation
