Two core principles behind mastitis control are to minimise the number of bacteria on teat skin and to maximise & maintain teat end health.

Whilst pre-milking teat preparation is not routinely used in most Australian herds, there is good evidence that targeted use can be of significant benefit.

In situations where there is excessive exposure of teats to mud and/or faecal material, the introduction of a pre-milking wash & dry routine can significantly reduce the number of bacteria on the teat surface and hence the risk of mastitis.

Removal of this contamination also allows the teat disinfectant to get to the skin, maximising the chances of both killing bacteria and getting emollient to the skin surface to improve teat skin health.

Remember that "gold" standard is to have cups going onto clean, dry teats after the cow has had a milk let-down.

An issue on the horizon for many dairy farmers is an expected rise in the cost of iodine teat disinfectants due to a rise in the cost of raw materials.

Whilst the extent of the price rise may be variable, some manufacturers have indicated that the price of a "ready-to-use" iodine based teat disinfectant may rise by about $70 for a 200 litre container over the next few months.

This would increase the cost of teat disinfection by about 0.7 cents/dose - for a 300 cow herd, that is about $2 per milking.

What are the options or alternatives?

On a typical dairy farm, the milking process contributes about 60% of the risk of mastitis on that farm.


Countdown has given us a great set of definitions for best practice, and Dairy Focus has now added the ability to precisely assess and measure each element of mastitis risk in the dairy and then combine them into an Overall Mastitis Risk Score.

We have now scored nearly 100 dairy sheds around Australia using the Dairy Focus Mastitis Risk Assessment,

The results show the key factors most commonly associated with increased risk of mastitis in our herds.

We have summarised these findings in a newsletter - Managing Mastitis Risk in Lactation - The Dairy.
