Automatic Cluster Flush System

Cluster flushing is a very effective way of controlling the transfer of contagious mastitis organisms from cow to cow, during milking and may have some effect on environmental mastitis organisms, however, if environmental organisms are the problem, cluster flushing may not be the answer. The best way to determine the type of problem is to have samples tested. We can arrange for samples to be tested by a specialist veterinary laboratory, if required, just contact Steve Gibson on 07725 241938, for more information. Alternatively contact Gloucester Veterinary Laboratory direct on 01452 541663, quoting Cotswold Dairy Equipment as the contact source and they will be happy to assist you.

The Cotswold Automatic Cluster Flush system is a very effective way of sanitizing the milking units between cows and so minimising the transfer of contagious mastitis organisms, with a clean cluster on every cow.

The process is fully automatic, individual unit flushing being initiated by the cluster remover on swingover herringbone and most other parlours and whole side flushing by the vacuum gate controls, on doubled up herringbone parlours. Doubled up herringbones can alternatively be operated by a separate push button (one per side) if required.

Once it is activated by the vacuum signal, the cluster flush control module completes the cycle of two flushes, (water and peracetic acid 0.5%) leaving the cluster ready to put on the next cow. We now have a compressed air operated automatic cluster drop valve available, as an option, which allows the ACR ram to lower the cluster when flushing, thus aiding drainage.

The unique liquid/pressure cylinder, designed and manufactured by Cotswold, means that unlike other systems on the market, no water/peracetic acid mix goes through the solenoid valves, only compressed air. This makes for a much more reliable system and cuts down on expensive solenoid valve replacements.

Customer Recommendations :-

 "We Installed the Cotswold clusterflush system in July 2010 after a cell count problem occurred, in our 100 cow herd when we fitted a new 10/10 herringbone parlour.

My rolling cell count was then around 275 to 300 and it is now 67 to 80. Mastitis cases are 23%, which is well below the average of 36% and we have had no cases of mastitis in fresh calved heifers to date. We have had no problems with the clusterflush since it was installed and whilst it is obviously not the complete answer to mastitis control it has been a great help.

I would thoroughly recommend the Cotswold system and would now not milk without it."

Mr Barker,

Milking 100 cows in Buckinghamshire.


"We had been battling with increasing cell counts for some time and had tried various spray systems and routines without much success. Since installing a Cotswold cluster flush system in June 2011, our cell counts have more than halved and continue to fall.

The Cotswold cluster flush system has been a sound investment and has worked faultlessly since it went in."

Andrew Blaney,

Managing 200 cow plus herd in Northern Ireland


"We are currently milking 130 cows through a 10/20 herringbone parlour and since we had the Cotswold cluster flush system installed by our local dairy engineer, Gareth Howells, we have been very pleased with the results.

We have seen a dramatic reduction in clinical mastitis cases from 5-10 cases a month to 2 cases in the last four months since the cluster flush has been working and the cell counts are continuing to decrease every month, with new calved cows now coming back into the herd mastitis free.

We have found the Cotswold system to be very straightforward, reliable and effective and would happily recommend it to anyone."

 "The Cotswold cluster flush system is working very well and for the last month results

came that there are no new cases of contagious mastitis.

I am very pleased with the whole system both the milking system and the back flush.
Now the milk produced is climbing up to new records for my animals ( this is the first
time to reach that milk production in that month of the year).
I had a lot of visitors in my farm for the last month and I highly recommend the back
flush system for them( i told them to have the new Fullwood equipment in the first place,
then the Cluster flush system and then the Auto ID if we arrange the priorities) and I
think it will be very helpful because all of our cows are kept on dirt, clay or sand in Egypt
I feel also that Cotswold system is very compatible with Fullwood equipment and I would
like to thank Shane, the Cotswold engineer for his work"
