Quarter-based selective dry-cow treatment using on-farmdiagnostic tool
Expectation to decrease use of antibiotics at drying-off by 50 % while maintaining udder health.
- With selectve dry cow therapy, infected cows may be treated with an antimicrobial only or with a combina-
tion of antimicrobial and a teat sealant at the end of lactation, while uninfected cows receive only a teat
- Introducing such a treatment strategy will, of course, generate new costs, mainly costs for diagnostic tests
and extra labor for sampling and conducting the test (for on-farm tests). On the other hand, less antimicrobials are used and costs for drugs and labor for administering drugs are saved.
- Selective dry cow therapy is one potential strategy for achieving a more judicious use of antimicrobials.
