Combatting inefficient nitrogen use in dairy cows

Feed efficiency is more than ever a concern on farms to allow animals to meet their genetic potential and to maximise farm profitability. This parameter has a great influence on production costs, animal performances and environmental releases. Gains are still be found in dairy cows, notably by increasing the efficiency of nitrogen utilisation. In dairy cattle, feed efficiency can be defined as kilograms of energy corrected milk produced per kilogram of dry matter intake (DMI) consumed. Its valu
