 Is
the drip of spray at the tip of the teat enough?
You won’t gain the milk quality
and financial benefits of teat disinfection if the spray only reaches the tip of
the teats.
Failure to cover the whole teat
of every cow at every milking is the most common error in teat spraying. All
benefits of correct product selection, preparation and handling are lost if the
disinfectant doesn’t reach every area of the teat skin that’s been touched
by the teacup liner.
About 20 mL of disinfectant
should be used per cow per milking to achieve good coverage. The spray equipment
and the operator’s technique both make a big difference to efficiency and
effective coverage.
Simple checks for coverage
include:
- looking at teats after
spraying – it can help if you use a product that’s clearly visible on
the teat skin after it’s been sprayed on
- calculating the volume
actually used per milking
- checking the time required to
spray 20 mL from the gun and comparing that with the actual time spent
spraying each cow.
