Excessive dietary crude protein, an imbalance of dietary amino acids, or both may result in reduced nitrogen use efficiency and high nitrogen losses which negatively affect farm economics and the environment. Avoiding overfeeding expensive dietary crude protein and balancing for amino acids in the ration of dairy cows may improve the profitability and sustainability of the dairy industry. Furthermore, targeting dietary protein or amino acids based on requirement across the lactation cycle may be beneficial. Research on how the dietary crude protein affects cow performance and nitrogen use efficiency throughout the lactation cycle and the association between plasma amino acid profile and cow performance will be summarized.
