A 30% reduction in mastitis cases during the first 60 days of
lactation, potentially worth £2,000/year per 100 cows
at the average clinical incidence, has been shown for the “Clean
Up, Seal Up” dry cow protocol being launched by Pfizer at
the Dairy Event (19-20 September, NAC, Warwicks).
The protocol is based on trial data and the company’s pan-European
Mastitis Reduction Programme, explains area veterinary manager
Ben Gaskell MRCVS. It involves treating cows at drying off with
conventional antibiotic dry cow tubes to clean up pre-existing
infection, followed immediately by a non-antibiotic internal teat
sealant to seal up each teat from the ingress of new infections
during the dry period.
“Aside from the clinical data on which the protocol is based,
the most compelling evidence of its effectiveness is that, in general,
farmers don’t stop once they’ve started it,” says
Mr Gaskell. “Targeted choice of antibiotic dry cow treatment
should be made in consultation with the farms’ own vet.”
treating two of the most common pathogens present at drying off
in cows carrying a mastitis infection, Staphylococcus aureus and
Streptococcus uberis, trials identified superior cure rates using
a cloxacillin-based treatment. The clinical trials on which
the new protocol is based were conducted using a cloxacillin dry
cow tube in combination with teat sealant.
According to Ben
Gaskell, the average UK dairy herd sees about 60 cases/year of
clinical mastitis per 100 cows, the majority of which can occur
during the first 60 days of lactation on many farms. During this
period, a 30% reduction would be about nine cases, at a saving
in the region of £220/case for treatment, discarded
milk and lower subsequent yield. “A resulting £2,000/year
saving per 100 cows will pay several times over the additional
cost of double treatment,” he adds.
Instructions for the Clean
Up, Seal Up dry cow protocol will be available from Pfizer’s
Dairy Event stand number 618 in Cattle Shed 9.
