Maintaining Milk Quality

Maintaining milk quality in late season under difficult conditions

It has been a mixed year for milk producers varying from some excellent early season weather to the wet conditions, posing challenges on maintaining milk quality standards. Based on current milk outputs, many dairy farmers may be extending the milking season to fill their quota and to take advantage of late season higher milk payments. Set out below are some tips for late season milk production.


TBC's, Thermodurics & TCMs

Machine Maintenance & Rubber condition

Review and replace rubberware as required. Cracked or pitted rubber ware can harbour bacteria leading to increased TBC & Thermodurics.

Acid washing done on a frequent basis in hard water areas can lead to pitting or cracks in rubber ware. Acid descalers should be mixed acids, containing a high content of Phosphoric acid combined with Nitric acid to ensure good detergency and scale removal. Osmonds MSR has been specially formulated to prolong rubber ware life.

Consider scale prevention versus removal. Theromodex is a unique solution to scale formation that totally eliminates the requirement to descale. Plus it prevents build-up of Thermoduric bacteria which normally is a problem in Autumn or in wet weather when these bacteria can get into the milkingsystem and get a grip in any scale present or cracks in rubber ware.

Wash Program

Review you milking plant cleaning program. Use detergents tested by Moorepark and on their current recommended list. Parlorsan, Supersan, Supersan Extra, Koldkleene, Parlorsan NC are all tested and approved.

Talk to your local Osmonds Rep about our Osmonds Assist Program where we can offer you specific wash programs tailored to your water and milking plant requirements.

Many TBC problems in late season milk production are linked to variation in final rinse water from wells on farm that may be affected by heavy rainfall. Thermodex used in the final rinse will eliminate TBC problems caused by rinse water.

TCMs are formed when unsuitable detergents or incorrect volumes are used or inadequate final rinsing. Osmonds Assist Program can be of help to offer solutions here.

SCC – Somatic Cell Count

As the lactation progresses SCC’s will increase and it is important to keep a close eye to ensure mastitis does not get hold.

Key focal points

  • Identify problem cows through Milk Recording or CMT testing.
  • Consider culling cows that have not responded to mastitis treatment during the year.
  • Identify bacteria strains by ‘milk sensitivity testing’.
  • Prevent the spread of mastitis by cluster dipping with Thermodex or Cluster Max.
  • Pre-foam, dip or spray cows to ensure mastitis bacteria are removed and prevented from entering the milk canal (Biolac Pre-Post or Duodip).
  • Disposal gloves should be used as they have been proven to reduce transfer of mastitis.

Post dipping has been proven to be the single most effective measure in the control of mastitis. The teat dip used should have good biocidal properties combined with a good emollient level to ensure good teat quality under difficult conditions. Duodip, Biolac Pre-Post, Lanodip, Mastex ,C-Dip work under variable Irish weather conditions.
