Protect Dry Cows to Prevent Mastitis
Posted by Michele Barrett

During the dry period, cows form a keratin plug that seals the teat canal against mastitis-causing pathogens. However, research shows not all cows will produce this plug, which can leave them two times more likely to develop a post-freshening mastitis infection.1

Administering a teat sealant helps ensure that cows get protective coverage and can minimize production loss during lactation. ORBESEAL® is an inert, nonantibiotic internal sealant that plays an important role in a dry cow program. In a 2003 study, cows treated with ORBESEAL and a dry tube had a 33% reduction in infection between dry off and their first 60 days of milk production compared with cows treated with only a dry tube.2

Watch the video to learn more from Dr. Michele Barrett, DVM, Dairy Technical Services, Zoetis, about the role of the keratin plug in preventing infection and how ORBESEAL can keep your dry cows protected.

Refer to the ORBESEAL label for complete instructions on proper administration at dry off and removal at freshening.
