Cattle
Antibiotic Free
DRYZEN® is an internal teat sealant (ITS) containing bismuth subnitrate. It’s used to prevent new mastitis infections in dairy cows and heifers over the dry period.
Proven to be non-inferior to Teatseal® in preventing clinical mastitis1
A comparative study of syringe ergonomics demonstrated that DRYZEN® is delivered with almost half the effort of Teatseal®1
Packaged in buckets made from recycled plastics.
DOSAGE AND ADMINISTRATION
Care must be taken not to introduce pathogens into the teat. Accidental introduction of bacteria into the quarter during insertion of the intramammary syringe can result in serious mastitis. It is essential that strict aseptic techniques are used for the infusion of this product as it possesses no antimicrobial activity.
Thoroughly clean and disinfect teats prior to infusion of the product. Ensure sufficient time is allocated to treat each animal. Disinfect and treat one teat at a time.
Ensure animals are appropriately restrained in hygienic conditions. Keep syringes clean. To avoid contamination, do not immerse loose syringes in water.
Start with a visibly clean, dry teat and udder. If teats are obviously dirty then clean off dirt and wipe each teat completely dry. Strip fore milk and discard.
Thoroughly disinfect each teat end by gently scrubbing with Virbac Antibacterial Teat Wipes or cotton wool balls moistened in 70% methylated spirits and 30% clean water. Use new wipes or cotton wool balls until both teat end and swab are visibly clean.
If required, administer a suitable dry cow therapy according to the product label, and massage this into the udder before administering DRYZEN®. Repeat disinfection of teat prior to insertion of DRYZEN®.
Remove the cap from a DRYZEN® syringe, being careful not to touch the nozzle. Insert the nozzle into the teat canal with minimal penetration (up to 3 mm) while avoiding contaminating the teat end. Infuse the contents of the syringe into the teat while gently pinching the top of the teat. Do not massage the product into the udder.
Repeat the process on the remaining teats. Apply a teat spray and confine the treated cows to a yard where they should stand for at least 30 minutes to allow the teat canal to close.
