A plan plus attention to detail makes a difference

Craig Gallpen decided that it was time to do something about the hassle and cost of dealing with mastitis in their 450 cow herd that milks three-times-a-day in the Riverina.

Craig was not only disappointed with the cost of treating clinical cases, but culling due to mastitis was affecting their ability to achieve and maintain herd numbers.

Dairy Focus always applies the Countdown Downunder principles and guidelines over five key areas of mastitis risk – drying-off, calving, lactation, environment and culling.

We started by getting milk cultures from high cell count cows and clinical cases. These showed a mixed bag of contagious and environmental bacteria (especially Strep uberis and E. coli).

The next step was to conduct a Dairy Focus Mastitis Risk Assessment of the dairy. This is an assessment of every part of the milking process that can influence the risk of mastitis - including the cows, the people & the machines.

The Gallpen dairy scored an Overall Mastitis Risk Score of 31 points out of 60 at this initial visit, meaning that the dairy and milking process rated as “High Risk” for the spread of mastitis.

This became the start of a process to reduce the risk of mastitis not just in the dairy, but across all five areas mentioned above.

Working with Craig and herd manager, Rachael Napier, a comprehensive plan was developed to cover all these areas, with a particular emphasis on staff education and training.

Improved milking protocols, including the use of milking gloves and strict attention to best possible coverage of teats with teat spray were key factors in reducing the risk of spread in the dairy.

The introduction of a “wash & dry” policy for teats prior to milking during times of high environmental risk of mastitis was a cornerstone of this culture, and drastically reduced the effect of wet and muddy weather.

“We created a culture in the dairy of how things are done”, said Craig.

Poor teat end condition was also a critical mastitis risk factor - this required a change of shells and liners to get the teat ends to a satisfactory condition.

Attention to detail in the treatment of clinical cases gave Rachael the control she needed for more successful outcomes.

A Dairy Focus Drying-Off Strategy discussion led to strict drying-off and dry-off treatment protocols including the use of Teatseal, and a Dairy Focus Calving Strategy was developed to reduce the risk of Strep uberis infections at calving.

These policies were implemented, and are now regularly reviewed each year to ensure they remain current.

Experience has shown that mastitis problems do not develop overnight and neither are they resolved overnight – it takes time, but attention to detail is always rewarded.

In fact, it took the Gallpen farm 12 months before cell counts were consistently below 100,000.

Their most recent Overall Mastitis Risk Score in the dairy was 8 points out of 60 - well into the "Low Risk" category for mastitis - and clinical cases are now at their lowest level ever.

“Our mastitis plan has been the ultimate for me”, said Craig, “I would hate to back to where we were.”

“People ask me what we did, and I just think they haven’t realised it isn’t one thing, and that they have a whole process in front of them.”

But it was Rachael who best summed up the current situation, “We have a pretty good system now.”


Does stage of lactation or age affect the cause of mastitis?

Our last newsletter described the first results of the large mastitis survey in Australia conducted by Dairy Focus and funded by Pfizer Animal Health, which found that 90% of clinical mastitis was due to four major bacteria - Strep uberis, Staph aureus, E. coli & Strep dysgalactiae.

But are any particular bacteria more common at different stages of lactation? Does the age of the cow make any difference?

The stage of lactation appears to have had little influence on which of the four major bacteria were isolated in this survey.

Strep uberis remained the dominant pathogen at all stages of lactation, with no clear trends of increasing or decreasing rates of Staph aureus, E. coli or Strep dysgalactiae.



In terms of the cows' parity (number of calves), the results also showed a reasonably consistent pattern across all age groups - Strep uberis being the most common at all ages, although it was even more common in first calf heifers.



Clearly, Australian dairy herds need to ensure their mastitis control programs take proper account of Strep uberis at all ages and at all stages of lactation.

Rob Moyle's "Movember" challenge!

Instead of growing a “mo” for Movember, Rob Moyle intends to shave his long time “mo” off - provided he reaches his target of $1000 donated to the Movember cause.

Not only that, but if he achieves $2000 donated to Movember, his crop of hair will go too!

‘‘The mo has been a permanent fixture for 30-plus years,’’ he said.

‘‘My two kids have never seen their father without it, and if we can raise enough, the hair will come off as well.”

At Dairy Focus, we reckon that is a very scary thought!

Rob wants to raise awareness of the importance for men of his vintage to have the “all important check up”.

The Movember campaign aims to raise vital funds and awareness for men’s health, specifically prostate cancer and male mental health.

To make a donation and help Rob remove his mo and his hair, log-on to www.movember.com.au and search Rob Moyle, or follow this link Mobro.co/robmoyle
