Breeding programmes in dairy cattle have been successful in the past by selecting for high milk yield, effectively doubling productivity over the past 50 years. However, this approach is reaching a plateau, with minimal improvements expected in the future.

Research to date has addressed this problem by looking at ways to reduce the cow’s urinary urea nitrogen concentration, but this has involved mitigation techniques that paint the cow as the problem rather than the solution.
