High-quality forage is an important component of the dairy cow diet in pasture-based milk production systems. Commonly used pasture is characterized by good digestibility, and a high protein concentration. It is important that these diets are well balanced since excess protein (particularly rumen degradable protein) generates excess ammonia in rumen and blood and increased urinary N excretion. Excessive nitrogen (N) generates inefficiencies due to higher energy expenditure for its metabolism and greater environmental impact.
