Low Cell Count, High Mastitis incidence.?

After several visits to investigate an issue with mastitis
The milking Machine was Tested no issues.
Pre and post cleanliness was very good.
The teats were sprayed, 100% contact
The beds were sand, cleaned twice a day, re-covered once a month all isolated areas cleaned
Water troughs cleaned every other day.

A bacteriology test was taken the cause was Streptococcus uberis
These are environmental organisms commonly found
In manure and other organic matter, including bedding.
Poor udder cleanliness, inadequate stalls management,
And damaged teat ends also appear to increase
The risk of spreading S. uberis to uninfected cows.

S. uberis will spread to uninfected cows through environmental
Contact. Reducing environmental contact
With S. uberis is especially important in the early dry
Period. As with all environmental organisms, maintaining
A clean and dry environment for cows to lie in is
Of utmost importance. In particular, the use of inorganic
Bedding (sand) will reduce the environmental contamination
With these bacteria

So all the above were above adequate this was becoming very baffling.
However on one morning visit the farmer himself was milking and when a slow cow was being milked he would proceed to use the volume wash hose to clean the cows hoofs with no control over where the water was being sprayed, resulting in water dripping down to an open teat end regardless of whether it had been sprayed, it took some convincing to stop this procedure.

Water use in the milking process should be kept to a minimum. If water is used, be
Sure to only wet the teats and not the entire udder. It is nearly impossible to dry the udder
Generally, the Use of water in the parlour results in increased mastitis and higher bacteria levels in milk.
All Teats should be thoroughly dried with a single service,

The End result is a reduced amount of Clinical mastitis .
