Udder Doctor Workshop: Dr. Andrew Johnson

Udder Doctor Workshop by Dr. Andrew Johnson

Dr. Johnson, world renowned dairy consultant from Wisconsin, USA presented the 'Udder Doctor' workshop in Tocumwal on 29 May 2014. Dr Johnson discusses a number of topics relating to mastitis. Dr Johnson has consulted in 26 countries and 45 states on dairies ranging from 20 to over 20,000 dairy cows.

Somatic cell count (SCC) is an indicator of the quality of milk. High SCC means high white blood cells; they are “like the policeman that attacks the bad guys”.

High cell count means your cow is fighting bacteria.

A farmer decides their SCC; they must feel comfortable with their decision. All dairy farmers can have a SCC of 100,000, but how many cows would be on the bucket with the milk discarded?

A farmer’s milking routine is critical (full prep, part prep or no prep) … routine is important!

See Dr Johnson’s prescribed 5-Step Milking Routine. The use of this full preparation is easier in a 90 degree or herringbone dairy than a rotary.

With this preparation, the cows actual milking time is less once they get the routine as the full let down takes away the dribble phase.

This preparation also discourages the over milking that occurs at the start of milking when cows have only let down the milk contained in their teat cistern. She then moves into the dribble phase, which causes cup slip especially in the back two teats.

Dr Andy Johnson, the Udder Doctor, advises five steps to a good milking routine to help reduce environmental mastitis and ensure you are milking a clean, dry, well stimulated teat.

Steps involved in a good milking routine:

Step 1 – Wear well-fitting gloves to reduce the risk of bacterial contamination to cows and keep the gloves clean with a bucket of an iodine and water mix

Step 2 – Apply pre-milking sanitiser by using either a clean dry cloth, or pre dip each teat with an iodine and water solution (or spray thoroughly)

Step 3 – Wait 30 seconds and dry the teats and squirt (strip) the teats and teat ends (or use a teat scrubber) to encourage the milk letdown process

Step 4 – After a lag time of 90 seconds, attach the teat cups and align the cluster

Step 5 – After milking, use a dip on each teat, making sure to get full coverage.
