Drying off and teatsealing represent an important part of mastitis control. Performed correctly, it will have the best results and make the investment worthwhile.
The way dry cow therapy is used has a major impact on how effective it is i.e. poor application may lead to a reduced cure rate...
1. Hygiene hygiene hygiene!
Teats must be thoroughly cleaned to remove any bugs present on the teat end. If not, it is highly likely that these bugs will enter the udder and cause severe infection
Clean teat ends by vigorously rubbing the teat end with the 70% alcohol swabs or wipes provided, until they come away clean.
Clean one teat at a time, starting with the front teats to avoid contamination from your arms/hands. After cleaning, give the intramammary without letting go of the teat end to avoid contamination. This way you clean and treat each teat one at a time.
Do not touch the nozzle of the syringe once the cap has been removed.
Only insert the tip of the syringe 2 - 3 mm, NOT all the way in.
Gloves should be worn, and these should be kept clean and dry during the process.

2. Speed of application
Correct application of DCT takes time! One person can correctly treat 20 cows per hour
3. Teat end damage
The antibiotic tube must only be partially inserted (less than 3mm) into the teat canal to minimise teat end damage and reduce introduction of bacteria into the gland.
Other Key Points
Make sure that your staff are fully trained in the administration procedure. We are happy to come and spend an hour or so going through the procedure with them to get them up to speed.
Record each cow number, treatment and date. Ensure that withholding periods are observed if cow calves earlier than expected.
Mark cows clearly when treated so if a cow jumps a fence, she won’t be accidentally milked.
Put cows into a clean paddock following drying off i.e. avoid effluent or recently grazed paddocks.
Allow cows to walk back quietly, without running.
