Size can make a significant difference in the cost of finishing hogs, according to new research from the U.S. Department of Agriculture.
We don't think it will come as a surprise to pig farmers, but an analysis from USDA's Economic Research Service found that larger U.S. hog finishing operations generally faced lower costs to add 100 pounds of weight to hogs than smaller operations.
The finding is based on nationally representative surveys conducted across five benchmark years: 1998, 2004, 2009, 2015 and 2020.
Although production costs varied considerably by year and from one farm to another, USDA found a consistent relationship between increasing operation size and declining costs per 100 pounds of gain.
That cost advantage helps explain one of the most significant structural changes that has occurred in the U.S. pork industry over the past three decades: hog production has increasingly shifted toward fewer and larger operations.
Why Do Larger Hog Farms Have Lower Costs?
Economies of scale are an important part of the answer.
Buildings, equipment and other capital investments create ownership expenses regardless of how many hogs move through an operation.
Larger finishing operations can spread those expenses across more animals, reducing the cost associated with each unit of production.
USDA also found that the opportunity cost of unpaid labor was generally lower on a per-unit basis for larger operations.
For producers, that distinction is important.
Expanding an operation does not necessarily make buildings, equipment or labor cheaper. Instead, additional production can allow some of those expenses to be distributed across a larger number of hogs and pounds of gain.
The result can be a lower production cost per unit.
Consolidation Reshapes U.S. Hog Production
The cost findings are part of a much broader examination of changes occurring within the U.S. pork industry.
USDA's Economic Research Service published The U.S. Hog Industry: Structural Change, Production Systems and Costs, and Manure Management in June 2026.
The study examines changes in farm numbers, production contracts and farm size, as well as differences in production costs, management practices, housing and manure management.
Over the past 30 years, U.S. hog production has consolidated into fewer and larger operations.
The relationship USDA observed between farm size and finishing costs provides some economic context for that shift.
Operations able to distribute fixed and ownership costs across larger numbers of animals may gain efficiencies that can be harder to achieve on smaller farms.
That can become particularly important during periods of narrow producer margins.
Bigger Does Not Mean Costs Are Falling Everywhere
USDA's findings should not be interpreted to mean that hog production itself is becoming cheaper.
More recent years included in the research generally show higher production costs.
USDA attributes that increase primarily to higher input prices over time.
That means two trends can occur simultaneously: larger farms can maintain lower per-unit costs relative to smaller operations while producers across different farm sizes still experience increasing expenses.
Feed, labor, energy, buildings, equipment and other inputs continue to affect the economics of pork production regardless of farm size.
Scale can help distribute certain expenses, but it cannot insulate producers from rising input prices.
What Does This Mean for Hog Producers?
The research underscores the financial pressure that can encourage consolidation within livestock production.
A modest difference in the cost of adding 100 pounds of hog weight can become substantial when multiplied across thousands of animals.
For existing producers considering expansion, however, scale alone does not guarantee better profitability.
Adding finishing capacity can require substantial capital investment while creating additional requirements for labor, feed sourcing, animal health, manure management and marketing.
The USDA research is therefore more useful as evidence of the economic advantages that have historically accompanied greater scale than as an argument that individual farms should necessarily become larger.
For smaller operations, the findings also reinforce the importance of knowing individual production costs and identifying areas where efficiencies can be gained without necessarily adding substantial capacity.
Efficiency Will Remain Key for the U.S. Pork Sector
The long-term shift toward larger hog operations is unlikely to be explained by a single factor.
Market access, production contracts, technology, labor availability, financing, environmental requirements and succession decisions can all influence the size and structure of farms.
USDA's research adds production costs to that picture.
Across more than two decades of benchmark data, larger finishing operations have generally been able to add weight to hogs at lower per-unit costs.
At the same time, rising input prices mean efficiency remains important for operations of every size.
For pork producers, the bottom line is not simply that bigger farms have lower costs. It is that knowing precisely where those cost advantages originate, particularly capital utilization and labor efficiency, can help farmers evaluate where improvements may be possible within their own operations.
