Alarming Disconnect: January 2025 Dairy Production Report Reveals Strategic Misalignments as Trade Tensions Loom

Powder inventories surged 41%, while processors accelerated production despite looming trade wars. The January dairy products report exposes alarming disconnects between market signals and manufacturing decisions, threatening processor and farm profitability as spring production increases.

EXECUTIVE SUMMARY: The January 2025 Dairy Products report reveals troubling production misalignments that demand immediate attention. NFDM production jumped 11% despite inventories already 41% above last year, while cheese and butter showed minimal growth despite increased milk supply. Italian cheese varieties (+2.2%) outperformed American types (+0.2%), suggesting shifting market preferences. Meanwhile, processors appear to redirect components toward consumer packaged goods like ice cream (+20.1%) and cream cottage cheese (+18.0%) while neglecting export-oriented products just as trade tensions escalate with Mexico. These patterns create significant price risks as spring flush approaches and raise questions about long-term strategic planning throughout the supply chain.

KEY TAKEAWAYS:

  • NFDM production surged 11% to 154 million pounds while inventories climbed to 299.3 million pounds, up 41% year-over-year, creating a dangerous market imbalance
  • Italian cheese varieties outperformed American types, with mozzarella production up 3.6% while cheddar continued its 15-month decline.
  • Butter production increased merely 0.5% despite high component availability, as processors shifted cream to ice cream (+20.1%) and cultured products.
  • Whey protein concentrate production fell 10.4% while whey protein isolate jumped 19.9%, indicating a strategic shift toward higher-value proteins.
  • Regional production patterns show Western processors focused heavily on NFDM (+15.2%) while Central region facilities led in cheese (+1.8%)

Steam billows from dryers running at full capacity across America’s heartland, transforming rivers of milk into mountains of powder that increasingly threaten to overwhelm warehouse capacity. The USDA’s January 2025 Dairy Products report, released yesterday, exposes troubling misalignments between processor decisions and market realities. Manufacturers appear to be doubling down on precisely the wrong products while ignoring clear warning signals from domestic and international markets.

Cheese Production Reveals Contradictory Strategies

January cheese production data unveils a strategic repositioning that demands closer scrutiny from processors and farmers. Total cheese output reached 1.21 billion pounds, inching up a modest 0.8% from January 2024 despite component-adjusted milk production increasing 2.2% nationally. This restrained growth suggests processors remain cautious amid looming capacity expansions and uncertain demand signals.

ProductJanuary 2025 (million lbs)Change from January 2024Change from Expected
Cheese (Total)1,210.2+0.8%Below forecast
American-Style473.9+0.2%Below forecast
Cheddar326.1-1.4%Below forecast
Italian Types521.7+2.2%Above forecast
Mozzarella412.7+3.6%Above forecast

The most revealing aspect of January’s cheese data is the stark divergence between cheese categories. While American cheese production barely increased, at 0.2% above January 2024 levels, Italian varieties grew substantially stronger, at 2.2%. Mozzarella’s impressive 3.6% increase led this to 412.7 million pounds. This marks mozzarella’s third-highest January production, reflecting processors’ strategic pivot toward export-friendly and foodservice-oriented varieties.

Particularly concerning for farmers focused on American cheese components is cheddar’s continued decline, dropping 1.4% to 326.1 million pounds—marking the fifteenth consecutive month of year-over-year declines. While this represents a moderating decrease compared to previous months, the persistent weakness in a traditionally anchored U.S. dairy processing category raises fundamental questions about shifting consumer preferences and processor responses.

The Butterfat Allocation Mystery

The January report exposes a perplexing contradiction in butterfat utilization that demands explanation. How can butter production grow only 0.5% to 218.3 million pounds when component-adjusted milk production increased by 2.2% and butterfat yields reached near-record levels? The answer lies in a dramatic reallocation of fat to alternative product streams that offer processors better margins—but may ultimately undermine farm-level butterfat premiums.

Processors appear to redirect cream toward frozen and cultured products rather than churning butter, with ice cream production soaring 20.1% to 59.6 million gallons—the highest January level since 2016. Regular hard ice cream led the surge, but other categories followed: low-fat ice cream jumped 10.2%, frozen yogurt increased 14.1%, and cream cottage cheese production jumped 18%.

This strategic pivot coincides with concerning inventory accumulation. According to the USDA’s Cold Storage Report, butter stocks climbed to 270.2 million pounds by January 31st, representing a troubling 26% increase from December and 9% growth year over year. This inventory build-up during what should be the seasonal low point for butter stocks signals potential market imbalances that could eventually transmit back to farm-level component values.

Powder Markets: A Crisis in Waiting

The most alarming element of January’s report is the dangerous inventory accumulation in dry milk products. Despite already bloated warehouses, nonfat dry milk (NFDM) production accelerated sharply by 11.0% to 153.5 million pounds, creating what industry analysts increasingly call “a powder volcano ready to erupt.”

NFDM Inventory MetricsJanuary 2024December 2024January 2025% Change (YoY)
End-of-Month Stocks (million lbs)212.3256.1299.3+41.0%
Monthly Production (million lbs)138.3130.7153.5+11.0%
Monthly Shipments (million lbs)123.0106.5106.5-13.4%
Production-to-Shipment Ratio1.121.231.44+28.6%

The 41% year-over-year inventory increase to 299.3 million pounds represents approximately 90 days of domestic consumption—far exceeding healthy balance levels. Even more troubling, NFDM shipments collapsed by 13.4% compared to January 2024, creating a perfect storm of overproduction and underconsumption.

“Processors appear to be ignoring flashing warning signs in the powder market,” warns industry economist Maria Rodriguez. “With flat or weakening demand from Mexico and reduced interest from other international buyers, these inventory levels create downward price pressure that will only intensify as we approach spring flush.”

This inventory mismanagement becomes more significant given imminent trade disruptions with Mexico, America’s largest dairy export destination. Adding to market pressures, the sharp decline in skim milk powder production (37.6% to 35.5 million pounds) indicates processors may be abandoning products specifically formulated for international markets just as trade tensions escalate—a concerning strategic pivot that could damage hard-won market relationships.

Whey Complex Shows Mixed Results

The whey sector presented contradictory signals in January that further highlight processor indecision. Total dry whey production decreased slightly by 1.9% to 76.2 million pounds compared to January 2024, despite increasing cheese production that would typically generate more whey. This suggests potential processing constraints or strategic decisions to limit whey production amid uncertain markets.

More notably, whey protein concentrate (WPC) production fell sharply by 10.4% to 38.2 million pounds, with the WPC 25.0-49.9% category plummeting 17.6%—reaching record low production levels for January. Despite this production decline, WPC stocks decreased marginally by 3.6%, suggesting weakening demand across domestic and international channels.

Conversely, whey protein isolate production increased substantially by 19.9% to 17.1 million pounds, suggesting manufacturers focus on higher-value protein products. Meanwhile, WPI stocks decreased 5.7%, indicating that demand for these specialized products remains relatively robust.

Strategic Implications for Dairy Farmers

The January production data demand strategic responses from dairy producers facing these market dynamics. The disconnect between component-adjusted milk production increases (2.2%) and finished product growth rates suggests processors struggle to balance milk utilization against fragmented market signals efficiently. This challenge ultimately transmits financial risk back to the farm level.

Farmers should consider several proactive measures:

  1. Review component optimization strategies, particularly evaluating the ROI on protein-enhancing feed additives, given the weakness in American cheese production and strength in Italian varieties.
  2. Contact processors directly to understand their production plans during the upcoming spring flush period and align herd management accordingly.
  3. Evaluate milk marketing contracts to determine flexibility for directing milk to processors with more diversified product portfolios that are less dependent on NFDM.
  4. Implement voluntary production moderation during peak spring months to avoid contributing to already excessive powder inventory build-up.

Farmers must recognize that the traditional price signals from CME markets may be increasingly disconnected from actual product movement and inventory positions. The January report demonstrates that even as cheese and butter prices show relative strength on paper, the underlying supply-demand fundamentals suggest potential pricing corrections once inventory realities fully manifest in market prices.

Conclusion: Market Reality Check Needed

As the dairy industry navigates these complex production and trade dynamics, the approaching spring flush threatens to exacerbate already significant challenges. The traditional seasonal increase in milk production could trigger substantial price corrections unless processors realign production plans with market realities rather than continuing to build inventory positions that defy economic logic.

For dairy farmers, these production trends underscore the urgent need for greater transparency and coordination across the supply chain. The divergence between component-adjusted milk production increases and finished product growth rates suggests a processing sector struggling to allocate milk components efficiently against fluctuating demand signals. This challenge ultimately transmits financial risk back to those producing the milk.

The Economic Allure of South Dakota, Kansas, and Texas for Dairy Farmers

The economic temptation of shifting dairy businesses to South Dakota, Kansas, and Texas is undeniable, with significant cost savings. These states provide far cheaper production costs than dairy centers like California and Michigan. The low cost and availability of feed is a crucial influence. For example, South Dakota’s land prices are almost half those in coastal areas. Yet, feed costs in Texas dairy farms are nearly 25% cheaper. The Midwest and Southern areas provide rich territory and temperatures ideal for growing important feed crops like maize and alfalfa at a reduced cost. Consequently, farmers may acquire their feed locally, lowering shipping expenses and maintaining a steady, fresh supply.

Furthermore, labor expenses in South Dakota, Kansas, and Texas are crucial for increasing profit margins. These states have historically low minimum salaries and living costs, significantly reducing operating expenditures for dairy farms. For example, Kansas’ labor expenses are nearly 30% lower than the national average. Furthermore, these places have a larger workforce specialized in agricultural labor, contributing to cheaper salaries and the availability of experienced workers. This excellent combination of low labor costs and a plentiful supply of qualified personnel provides a favorable climate where dairy producers may maintain optimum staffing levels without incurring significant financial obligations in other states. As a result of the decreased operating expenses, South Dakota dairy farmers have a 5% larger profit margin.

Finally, the economic advantages make a strong argument for transferring dairy enterprises to these emerging dairy centers. By leveraging lower production costs, inexpensive feed, and cost-effective labor, dairy producers may achieve larger profit margins and more sustainable business models, putting them in a competitive position.

Geographical Advantages and Water Resources in Dairy Relocation: South Dakota, Kansas, and Texas

The geographical advantages of migrating to states like South Dakota, Kansas, and Texas go well beyond land availability; they also provide an astounding range of water resources. These states are endowed with ample groundwater, critical in the dairy business, where water use is high. Kansas has 10% more groundwater availability than the national average.

Furthermore, these areas have witnessed a significant investment in dairy processing facilities. This implies that proximity to processing factories decreases transportation costs and time, directly impacting the bottom line. This infrastructure improves dairy farming’s economic viability while ensuring environmental compliance by lowering carbon footprints.

Understanding the Regulatory Landscape: The Key to Leveraging Favorable Compliance Frameworks for Dairy RelocationUnderstanding the regulatory environment is critical for any dairy farm contemplating migration. South Dakota, Kansas, and Texas have more favorable regulatory environments than California or Michigan, where rigorous environmental rules may create substantial operating challenges. Policymakers in these middle-income countries realize the economic advantages of attracting dairy enterprises, which has resulted in more attractive compliance regimes for farmers.

South Dakota’s environmental rules are designed to be both rigorous and practical, finding a balance that protects the environment while increasing agricultural output. Farmers benefit from more straightforward permitting procedures and aggressive governmental assistance, which make compliance more attainable. Kansas and Texas have regulatory environments that balance environmental care with economic realities in dairy production. Notably, Texas dairy producers have 40 percent fewer ecological rules. Both states have made significant investments in technology and procedures that will assist farms in meeting environmental regulations at a reasonable cost. South Dakota has spent $100 million on dairy processing plants.

In contrast, states such as California have implemented more stringent regulations governing water consumption, air quality, and waste management. These often result in increased operating expenses and complex regulatory obligations. While these restrictions seek to address environmental problems, they may also drive dairy farmers to states that take a more balanced approach, such as South Dakota, Kansas, and Texas.

Thus, while contemplating relocation, it is critical to grasp the area’s regulatory intricacies. A favorable regulatory environment minimizes compliance requirements while contributing to dairy enterprises’ long-term viability and profitability. Deciphering these distinctions may help dairy farmers position themselves for success, allowing them to reap the advantages of shifting to states that promote agricultural expansion and environmental stewardship.

How Once-a-Day Milking Impacts Quality, New Study Reveals: Boosting Milk Proteins

Uncover the effects of once-a-day milking on milk protein quality. Could this approach boost your dairy production? Dive into the breakthrough study’s latest revelations.

Understanding the intricacies of dairy farming can profoundly affect milk quality, with milking frequency emerging as a crucial factor. A recent study by Riddet Institute PhD student Marit van der Heijden, published in the journal Dairy, illustrates how milking frequency can alter the protein composition in milk, potentially transforming dairy practices. 

“Milk from a once-a-day (OAD) milking system contained higher proportions of αs2-casein and κ-casein and lower proportions of α-lactalbumin,” said Van der Zeijden.

This study compares the effects of OAD and twice-a-day (TAD) milking over an entire season, revealing significant changes in protein proportions that could affect milk processing and quality.

This research underscores the impact of milking frequency on milk protein composition. By comparing once-a-day (OAD) and twice-a-day (TAD) milking, the study reveals how these practices affect specific milk proteins. Conducted by the Riddet Institute, the study analyzed protein composition over the entire milking season, providing insights that previous short-term studies should have included. These findings highlight the relationship between milking practices and milk quality, with potential implications for dairy management and processing.

Protein Composition Shifts with Milking Frequency: Implications for Milk Quality and Processing

ParameterOAD MilkingTAD Milking
αs2-caseinHigher ProportionsLower Proportions
κ-caseinHigher ProportionsLower Proportions
α-lactalbuminLower ProportionsHigher Proportions
Average Milk Solids ProductionDecreased by 13%Variable
Milk YieldReducedHigher

The study uncovered noteworthy disparities in protein proportions contingent on the milking regimen employed. Specifically, milk derived from an OAD milking system exhibited elevated levels of α s2 casein and κ-casein, juxtaposed with a decrease in the proportion of α-lactalbumin. These findings underscore the impact that milking frequency can have on milk’s nutritional and functional properties, potentially influencing its processing characteristics and overall quality.

Van der Zeijden’s Findings: A New Paradigm for Dairy Processing and Quality Management

Van der Zeijden’s findings reveal significant effects on milk processing and quality due to changes in protein composition from different milking frequencies. OAD milking increases α s2 casein and κ-casein levels while reducing α-lactalbumin. These proteins are crucial for milk’s gelation and heating properties. 

Higher κ-casein in OAD milk can enhance gel strength and stability, which is beneficial for cheese production. κ-casein is key in forming casein micelle structures, improving cheese texture and firmness. 

Lower α-lactalbumin levels in OAD milk may impact milk’s heat stability. α-lactalbumin affects whey proteins, which are heat-sensitive and play a role in denaturation during pasteurization or UHT processing. Less α-lactalbumin might result in smoother consistency in heat-treated dairy products

The protein composition differences from milking frequency require adjustments in dairy processing techniques to optimize product quality. Dairy processors must tailor their methods to harness these altered protein profiles effectively.

Methodical Precision: Ensuring Robust and Comprehensive Findings in Van der Zeijden’s Research

The methodology of Van der Zeijden’s study was meticulously crafted to ensure reliable and comprehensive findings. Two cohorts of cows at Massey University research farms in Palmerston North followed different milking regimes—OAD and TAD. Both farms used pasture-based feeding, with TAD cows receiving more dry matter supplementation. 

Eighteen cows, evenly split between the two systems, were selected for homogeneity. Each group consisted of three Holstein-Friesians, three Holstein-Friessian x Jersey crosses, and three Jerseys, allowing for a direct comparison of milking frequency effects on protein composition. 

Over nine strategic intervals across the milking season, Van der Zeijden collected milk samples, capturing data at the season’s start, middle, and end. Samples were also categorized by early, mid, and late lactation stages, ensuring a thorough understanding of how milking frequency impacts protein content throughout the lactation period.

Dynamic Interplay: Seasonal Timing, Lactation Stages, and Cow Breeds Shape Protein Composition in Bovine Milk

FactorDescriptionImpact on Protein Composition
Milking FrequencyOnce-a-day (OAD) vs. Twice-a-day (TAD) milkingOAD increases proportions of α s2 casein and κ-casein, decreases α-lactalbumin
Seasonal TimingDifferent periods within the milking seasonVaries protein proportions due to changes in diet, environmental conditions
Lactation StagePeriods of early, mid, and late lactationProtein and fat content increase as milk yields decrease
Cow BreedHolstein-Friesian, Jersey, and crossbreedsJersey cows have higher protein and milk fat content, larger casein-to-whey ratio
Feeding SystemPasture-based vs. supplementary feedingImpacts overall milk yield and protein profiles

Several factors impact protein composition in bovine milk, directly influencing milk quality and processing. Seasonal timing is critical; protein levels can shift throughout the milking season due to changes in pasture quality and cow physiology. The lactation stage also plays a vital role. Early in lactation, milk generally has higher protein and fat levels, decreasing until mid-lactation and possibly rising again as the drying-off period nears. This cyclical variation from calving to preparation for the next cycle affects milk yield and composition. 

By considering seasonal timing, lactation stages, and cow breeds, dairy producers can adapt management practices to enhance protein levels in milk. This alignment with consumer demands boosts product quality. It informs breeding, feeding, and milking strategies to maximize milk’s nutritional and functional benefits.

Breed-Specific Insights: Jersey Cows Stand Out in Protein-Rich Milk Production

Van der Zeijden’s study provides detailed insights into how different breeds vary in milk protein composition, with a focus on Jersey cows. Jersey cows produce milk with higher protein and milk fat content compared to other breeds and a higher casein-to-whey ratio. This makes Jersey milk better for certain dairy products like cheese and yogurt, where more casein is helpful. These findings highlight how choosing the right breed can improve the quality and processing of dairy products.

Embracing Change: The Increasing Popularity of Once-a-Day Milking Among New Zealand Dairy Farmers

The appeal of once-a-day (OAD) milking is growing among New Zealand dairy farmers, driven by its lifestyle benefits. While most farms stick with twice-a-day (TAD) milking, more are shifting to OAD for better work-life balance. OAD milking reduces time in the cowshed, allowing more focus on other farm tasks and personal life. It also improves herd health management by providing more efficient handling routines. However, it comes with challenges like managing higher somatic cell counts and adjusting milk processing to different compositions. The move to OAD reflects a balance between efficiency and personal well-being without compromising milk quality.

The Bottom Line

Milking frequency significantly influences the protein composition of milk, impacting its quality and processing. Marit van der Zeijden’s study highlights vital differences; OAD milking leads to higher levels of certain caseins and lower α-lactalbumin, altering milk’s gelation and heating properties. These findings urge dairy producers to adapt practices based on protein needs. 

The research also reveals that breed and lactation stages interact with milking frequency to affect protein content. Jersey cows show higher protein and fat ratios. As OAD milking is popular in New Zealand, these insights can guide better farm management decisions, optimizing economics and product quality. Strategic adjustments in milking practices could enhance profitability and productivity, advancing dairy processing and quality management.

Key Takeaways:

  • Once-a-day milking (OAD) impacts milk protein composition, increasing α s2-casein and κ-casein while decreasing α-lactalbumin.
  • Variation in protein composition influences milk’s gelation and heating properties, affecting cheese production and heat-treated dairy products.
  • This study is unique as it evaluates protein changes over a complete milking season rather than relying on single samples.
  • Breed-specific differences, particularly in Jersey cows, highlight the importance of genetic factors in milk protein content.
  • OAD milking systems are gaining popularity due to lifestyle benefits, despite lower overall milk production compared to twice-a-day (TAD) systems.
  • Further research is needed to explore the environmental impact, specifically greenhouse gas emissions, associated with OAD milking systems.

Summary: Milk quality in dairy farming is significantly influenced by milking frequency, with a study published in the journal Dairy revealing that once-a-day (OAD) milking systems contain higher proportions of αs2-casein and κ-casein, while lower proportions of α-lactalbumin. This highlights the relationship between milking practices and milk quality, with potential implications for dairy management and processing. OAD milking increases α s2 casein and κ-casein levels while reducing α-lactalbumin, which are crucial for milk’s gelation and heating properties. Higher κ-casein in OAD milk can enhance gel strength and stability, beneficial for cheese production. Lower α-lactalbumin levels may impact milk’s heat stability, affecting whey proteins, which are heat-sensitive and play a role in denaturation during pasteurization or UHT processing. Less α-lactalbumin may result in smoother consistency in heat-treated dairy products.
