The following suggestions should be taken on board:
Treat all quarters of each cow with the same
treatment.
CMT (California Mastitis Test) test cows prior
to drying off to identify problem quarters. In
problem quarters, administer one lactating cow
tube every 12 hours for 3 milkings prior to drying
off. All milk should be discarded during this
procedure.
Dry cow antibiotic tubes and/or teat sealant
should be administered after the final milking.
Milk out the quarter fully before infusing the dry
cow antibiotic/sealant.
Disinfect the teat end vigorously, rub the teat
end for 10-15 seconds with cotton wool soaked in
methylated spirits.
Do not contaminate the nozzle of the antibiotic
tube before insertion into the teat canal.
Infuse the contents of the antibiotic tube into
the quarter hold teat-end firmly between
thumb and forefinger and with other hand, gently
massage the antibiotic upwards into the teat
(NOTE: This is not done with teat seal).
Teat spray (post milking teat disinfectant)
treated quarters immediately after infusion at a
rate of 20 cc/cow.
Record cow number, date and product details of
all dry cow treatments
Mark the cow (leg band or spray paint on udder)
so that cows that have received dry cow antibiotic
therapy can be readily recognised.
Do not leave cows in yards or soiled areas in
the period immediately after dry cow therapy
application.
Maintain dry cows separate from the milking
herd if possible and put dry cows in clean, dry
paddocks (particularly for the first two weeks
after drying-off) to reduce teat exposure to
environmental mastitis bacteria.
The cow is at a greater risk of new infection for
the first 3 weeks after drying off.
Keep a close eye on cows to identify new
infections.

Some farmers are teat sealing heifers now; but if being
done, because you have heifers calving down with
mastitis, then it must be done extremely carefully and
is a tough job.

You should cull cows that:
Had 3 or more clinical cases this year and had 2-3
high SCC readings during the year.
It is a waste of money treating these cows as they
will continue to spread infection to other cows
