Sealing The Future

Why choose Boviseal?

Boviseal has been tried, tested and trusted by farmers in Ireland for more than 15 years.

Not all teat sealants are the same. The use of Boviseal at dry off ensures the barrier against infection is present throughout the dry period and significantly reduces the incidence of subsequent intramammary infections and clinical mastitis1,2,3.


Boviseal prevents more than 1 in 3 cases of mastitis3,4.

Boviseal consistently achieves at least a 35% reduction in clinical mastitis incidence. A reduction in mastitis incidence means less need for antibiotic treatment.


Boviseal contains colloidal anhydrous silica.

Colloidal anhydrous silica is an essential component of Boviseal in the formulation. It gives body to the product and increases its viscosity.

The combination of ingredients produces a seal of optimum character and consistency, proven to prevent new intramammary infections and reduce the incidence of clinical mastitis acquired during the dry period.

Physical characteristics that are necessary for the sealant:

• A paste to be infused into the teat canal

• Solid characteristics to maintain it within the teat canal

• Rheological properties to allow movement; to adapt to the changing shape of the teat canal; maintain closure integrity and most of all, being able to hold its integrity regardless of the stresses that it encounters.

Boviseal has many years of research and development in producing the product. Changing the formulation will change the characteristics of the seal by altering the fluid dynamics of the seal. The properties of the fluid are fundamental to its action with each ingredient playing a vital role.


Boviseal is proven to work with or without a dry cow antibiotic.

The majority of scientific studies use Boviseal* as the teat sealant – proving its success and ability to prevent cases of mastitis acquired during the dry period. The huge amount of research, development and clinical trials that support Boviseal have proven that it may be used alone in the dry period to prevent new intramammary infections. This is especially important with the growing pressure to reduce antibiotic usage from government agencies, food retailers, consumers and milk processors. Selective dry cow therapy reduces the use of dry cow antibiotics but requires an effective teat seal throughout the dry period – this has been shown in many clinical trials with Boviseal1,3,4,5. This means that you can be confident the teat seal is working, with or without an antibiotic.


The Boviseal team from Zoetis offers in-depth support to vets and comprehensive training to farmers throughout Ireland.
