What’s Driving the New Era of Dairy Production? Insights from the Tri-State Dairy Nutrition Conference
In April, Volac attended the 34th Tri-State Dairy Nutrition Conference in Fort Wayne, Indiana - a key event bringing together leading nutritionists, veterinarians, and researchers to share the latest thinking in dairy production.
The discussions this year painted a clear picture: the US dairy industry has entered and established a new phase of production, driven by rapid advances in genetics, nutrition, and on-farm management, with the outlook pointing towards continued and sustained growth in milk component output.

The Rise of Milk Components
Milk component production was a consistent focus throughout the conference, reflecting its growing importance within the US dairy industry.
Corey Geiger, Lead Dairy Economist at CoBank, outlined how more than 80% of US milk is now used in manufactured products such as cheese, butter, and powders - increasing the emphasis on butterfat and protein rather than just milk volume.
He also noted that butterfat production is currently outpacing protein growth, which is creating challenges for cheesemakers and export competitiveness. At the same time, overall component production continues to rise, driven by significant genetic progress over the past decade. This trend is expected to play a key role in supplying the estimated $10 billion of new dairy processing capacity coming online in the US through to 2027.
Genetic Progress Driving Performance
The scale of genetic advancement within the US dairy herd was another clear thread across presentations. The most recent April genetic base adjustment has set a new benchmark, representing the largest base change in history.
This step change underscores the pace of the Holstein genetic revolution, which is not only reshaping on-farm performance expectations but also influencing the US position in global dairy markets.
This progress is increasing what cows are capable of producing, while simultaneously raising expectations around how effectively that potential is managed on farm.
Advances in Nutritional Strategy
Developments in dairy nutrition are continuing to evolve alongside genetic progress, with a greater focus on how nutrients work together to support performance.
Dr. Kelly Nichols of the University of California, Davis, discussed how improved nutritional modelling is helping to better understand the interaction between energy supply and amino acid balance, improving the efficiency of converting dietary protein into milk protein.
Dr. Adam Lock of Michigan State University highlighted how fatty acid supplementation can be used strategically to support both rumen function and butterfat production.
Together, these insights reflect a more integrated and precise approach to feeding high-producing dairy cows.
Managing the Transition Cow
The transition period was repeatedly highlighted as a critical stage in determining overall cow performance.
Dr. Lautaro Rostall-Congiano (University of Wisconsin–Madison) and Dr. Eduardo Rico (University of Pennsylvania) explored the biological pressures cows face during this period, including immune challenges, inflammation, and metabolic stress.
These factors can limit a cow’s ability to reach her full production potential, particularly in early lactation.
At the same time, Dr. Augusto Madureira highlighted how wearable technologies are enabling earlier identification of at-risk cows, allowing for more targeted management and improved outcomes.
A Strong Outlook for the Dairy Industry
Bringing these themes together, the overall outlook for the US dairy sector remains very strong.
With the industry now firmly in this new phase of production, continued genetic progress—combined with advances in nutritional strategies and technology adoption—is expected to drive sustained increases in milk component output.
However, as production continues to advance, the ability to consistently manage cow health, resilience, and performance at farm level will remain key to unlocking this potential.
Where This Fits for Volac
At Volac, these insights reinforce the importance of supporting cows through both performance and resilience.
As production intensifies and cows are pushed to achieve more, managing challenges such as nutritional stress, gut health, and hidden performance barriers becomes increasingly important.
It’s not just about producing more - it’s about enabling cows to perform consistently, efficiently, and sustainably.
