The landscape of dairy farming in the U.S. has undergone significant changes over the past two decades, reflected in both the declining number of licensed farms and the increasing volume of milk production. As this industry evolves, small dairy farms face critical questions about sustainability, profitability and the most effective methods for expansion. Lynn Olthof, a dairy management Ph.D. student at Michigan State University talked on a recent episode of Professional Dairy Producers’ (PDP) “Dairy Signal” about various modeling paths forward for expanding U.S. dairy farms.
The Decline and Growth of Dairy Farms
In the past 20 years, the U.S. has seen a reduction of approximately 40,000 dairies. This decline is most severe among smaller herds milking fewer than 200 cows, contrasting with an increase in herds exceeding 1,000 cows. The small farms face a choice: expand their operations to achieve more substantial profits or exit the business entirely. To assist these smaller dairies in navigating the changing industry, a study was conducted examining four potential expansion strategies for 250-cow dairy farms.
Examining Expansion Scenarios
The study explored four scenarios for expanding a typical 250-cow Midwest dairy farm. These scenarios aimed to identify the most profitable and efficient methods while minimizing risk:
Scenario A: Doubling the number of cows, land, barn capacity and other essential infrastructure.
Scenario B: By passing the land investment, instead using that capital to increase cattle numbers and facility capacity more drastically without changing the diet by purchasing more forages.
Scenario C: Similar to Scenario B, bypassing the land investment to increase cattle numbers and facility capacity more drastically while feeding a diet heavier in byproducts.
Scenario D: Investing in robotic milking systems alongside infrastructure, land and cow expansions.
Project Methods and Analysis
The analysis assessed return on investment and profitability over 10 years. Peer reviewed research, Extension articles, and dairy herd records determined average and standard deviation values for various factors such as milk price, feed cost and cow values, which were used within the Monte Carlo simulation to account for different market conditions. This allowed for a robust understanding of how each scenario would fare under varying circumstances.
Key Findings
Profitability: Scenario B emerged as the most profitable strategy, offering the highest net profit annually and a positive return on investment after 10 years.
Efficiency: Robotic milking systems in Scenario D provided the greatest predictability and the least labor costs per hundredweight.
Solvency: Scenario B demonstrated the lowest debt utilization, indicating a strong capacity to meet long-term financial commitments.
Considering Cash Flow and Risk
Cash flow analysis revealed that Scenario B had the highest likelihood of maintaining positive annual cash flow. It underscores that while profitability and cash flow are related, they should be assessed as separate metrics.
Sensitivity Analysis and Real-World Applicability
The sensitivity analysis provided an understanding of how external factors could influence the outcomes. Although scenario rankings changed when evaluating feed cost, milk price or robotic milk production, sensitivity analysis revealed few extreme scenarios that would change the ranking of scenarios.
The study highlights that while Scenario B is the most promising overall, each farm is unique, and these models are not one-size-fits-all solutions. Farms should consider their specific conditions, market access and financial health when selecting an expansion path.
Next Steps
With these insights, efforts are underway to develop a practical tool that small dairy farmers can use to plug in their own data and make informed decisions. By aligning expansion strategies with farm-specific needs, dairies can better position themselves for future success in a rapidly evolving industry.
