Growing protein levels could strengthen dairy exports and cheese production
The U.S. dairy industry is placing greater emphasis on increasing protein levels in milk as demand for protein-rich dairy products continues to grow around the world. Industry experts believe a stronger balance between protein and butterfat can help improve dairy processing efficiency and strengthen export opportunities.
A new report from CoBank’s Knowledge Exchange shows that over the past decade, butterfat production in U.S. milk has increased significantly. However, protein growth has been slower. Recent market signals are encouraging farmers to focus more on protein because pricing systems now place greater value on this milk component.
“In the U.S., butterfat gains have doubled protein growth over the past decade, driven largely by demand to fill underserved domestic butterfat markets,” said Corey Geiger, lead dairy economist with CoBank.
He added, “The dairy industry has successfully met that challenge, and U.S. butter exports are now historically high. At the same time, higher butterfat yields in milk have led to some significant challenges for cheddar and American-style cheesemakers, who rely on a more balanced ratio of butterfat and protein for optimal cheese quality and production yields.”
According to industry research, milk protein production recently began growing faster than butterfat production. This shift is important for cheesemakers, who depend on a healthy protein-to-fat ratio to produce high-quality cheese and improve manufacturing yields.
The United States remains one of the world's largest dairy exporters, but it continues to trail major competitors such as the European Union and New Zealand in overall milk protein content. These regions have maintained a more balanced relationship between protein and butterfat, helping them align with global dairy demand trends.
A protein-to-fat ratio above 0.80 is often preferred for cheese production. In recent years, many U.S. cheese manufacturers have needed to add extra milk protein solids because the natural ratio in milk declined. Improving protein content could reduce this challenge and support more efficient production.
For dairy farmers, protein and butterfat remain critical drivers of farm income. These components are essential for making products such as cheese, butter, whey, and milk powders that are sold in domestic and international markets.
“Fully restoring the protein-to-fat ratio of 0.83 from a decade ago will require years of sustained higher protein growth. And until protein production gains catch up to butterfat, the U.S. will need to find more domestic and international outlets for its growing butterfat supply,” said Abbi Groves, agricultural commodities economist with CoBank.
Experts note that increasing milk protein is more difficult than boosting butterfat because protein improvements depend heavily on genetics. Even so, U.S. dairy producers have made measurable progress, with protein output rising steadily in recent years.
Industry leaders believe continued investment in genetics, breeding programs, and protein-focused incentives can help restore a stronger protein-to-fat balance. While progress may take time, the trend is expected to support dairy profitability, improve cheese production, and enhance the industry's long-term global competitiveness.
