Teat Sealant

Give her an extra shield of protection during the dry period.

Keeping your cows’ udders safe during the dry period is of the utmost importance to maintain a healthy cow.

The streak canal is the mammary system’s primary line of defense, yet studies show 24% of cows do not form a keratin plug after six weeks of dry period, which is crucial to block new bacterial infections that cause mastitis. When UdderLife™ OptiShield™ teat sealant is administered, it settles in the lower portion of the streak canal, forming a physical barrier that mimics the cow’s own natural keratin plug.
