Rumen at the heart of feed efficiency

The rumen is actually the keystone of feed efficiency: it is the main first organ of the cow digestive tract. What can be done to further optimise it? Feed efficiency can be defined as the ratio between performance and feed consumption. In dairy farming, performance can be expressed by Energy Corrected Milk (ECM), which takes into account milk yield, but also protein and fat contents. Feed consumption is commonly expressed in kilograms of Dry Matter Intake (DMI). Production on feed intake is co
