When pasture is limited, grain and concentrates are easy fillers but can be expensive and its use must be managed in regards to animal health. The majority of dairy farms in Australia currently process grain by using the method of „dry-rolling‟. This is a process where grain with 10-12% moisture content is shattered and then fed to cows. The „shattering‟ of the grain increases its surface area which speeds up the rate of digestion in the rumen. In many other parts of the world such as the United Kingdom, grain is also „dry-rolled‟ but with much higher moisture.
