Designed for use at dry-off, with or without a dry cow intramammary antibiotic*, Internal Teat Sealants (ITS) like Cepralock® provides a secure seal of the teat canal for the prevention of mastitis over the dry period.
Dry cow antibiotic and ITS work differently and are not substitutes for each other. Dry cow antibiotics are used to cure existing infections when cows are dried off. ITS are used to prevent new infections in the udder.
Cepralock can be used in maiden heifers in herds where heifer peri-calving mastitis levels are clinically significant.
Cepralock’s formulation is based on proven concepts:
Cepralock has a dual-tip nozzle
- remove the upper cap for a partial insertion technique and insert the tube into the teat end (<3mm)
- minimises the risk of accidental damage to the teat sphincter, canal and keratin lining during administration
- reduces the risk of pushing infection into the udder at drying off
- Bismuth-based teat sealants used alone help to reduce the incidence of mastitis in cows that are free from subclinical mastitis at drying off and have a low somatic cell count
- A recent analysis of results over 10 years confirmed the use of teat sealants either alone or in combination with an antibiotic dry cow therapy significantly reduces the incidence of new intramammary infections and clinical mastitis cases
The formation of the keratin plug in the teat canal is often delayed in high-producing cows, leaving them open to infection. A New Zealand study1 showed a high proportion of cows did not develop a fully functional keratin plug until well into the dry period.
- 1 week after drying off around 50% of teats were still open
- 40 days after drying off 20% of teats were still open
