Extract

There is increasing government and consumer pressure on agriculture to reduce nitrogen pollution of the environment and EC legislation is now in place to reduce nitrate levels in drinking water. Dairy cows excrete large amounts of nitrogen and use of the Metabolisable Protein (MP) system (AFRC, 1992) which defines the dietary nitrogen characteristics and animal requirements, may reduce environmental pollution by increasing the efficiency of nitrogen capture.
