Poor pasture growth takes a toll
(it takes less than a minute to run each sample). This gives the option of removing the individual high cows and retesting the vat prior to the next pick up, to assess the impact of removing these cows.
Reducing the time taken to get a positive identification of ‘‘mastitis cows’’ means treatment is started sooner (or the decision to cull if severe), which increases the chances of the infection clearing up.
Once a cow has been treated, her somatic cell count can be checked to ensure her cell count before putting back into the vat.
