Primary content

Fat and protein

Cows’ milk consists of solids (milkfat, protein, lactose and minerals) in water, which makes up about 87% of the volume. The milkfat and protein components are those on which  companies base their farmgate milk prices. Since early 2017, milkfat is the more valuable component. 

Milk composition can vary between regions and seasons. This may be due to a number of factors, such as cow breed, age, nutrition and feed quality.

Initiatives

Dairy biosecurity

Dairy biosecurity is vital for protecting your farm. Dairy farmers and their advisors now have access to a new online biosecurity tool to build their skills and adapt their management approach to biosecurity risks.

Hay and grain reports

The hay and grain report is commissioned by Dairy Australia to provide an independent and timely assessment of hay and grain markets in each dairying region. The report is updated 40 weeks per year.
