With every downturn in the pork industry it has provided opportunities for operations to grow either through green field expansion or acquisition. We’ve seen this happen after 1999 and again after 2009. The industry has evolved in the past couple of decades and today I view it as mature with limited options for expansion.
With the closing of the Tyson Foods plant in Perry, Iowa, any growth in production needs to be accommodated by increased efficiencies in pork processing or by acquisition. Still, there are opportunities for producers today.
One of those opportunities is to consider converting sow farms into finish/ween-to-finish barns.
Why Consider Converting a Sow Farm?
This shift can provide significant cost advantages over new construction while ensuring existing facilities remain productive. However, repurposing a sow farm requires careful planning, particularly regarding permitting, facility modifications and financial feasibility.
Understanding Space Conversion
A typical gestation space in a sow farm is approximately 20 square feet per sow, accounting for a 2-foot by 7-foot stall with a 1-foot back alley and a 2-foot front alley.
If a 5,000-sow farm is repurposed, approximately 4,500 sow spaces can be converted into 6,000 finishing spaces. This transformation optimizes the available footprint while meeting the needs of a modern wean-to-finish operation.
The most critical aspects of converting a sow farm into a finishing barn is ensuring compliance with state permitting regulations. In Minnesota, the animal unit (AU) calculation differs between sow farms and wean-to-finish operations:
• Sows: 0.4 (AU) per head
• Wean-to-finish pigs: 0.3 (AU) per head
This means that converting a sow farm to a finishing site increases the animal unit count by 25%. If the new configuration exceeds the permitted capacity, a re-permitting process may be required. Addressing this before beginning the conversion can prevent delays and regulatory challenges.
Key Factors in Repurposing a Sow Farm
When assessing whether to convert a sow farm, several factors should be considered:
1. Salvage Value of Equipment
Many sow farms contain valuable equipment that can be repurposed in other facilities. Identifying what can be sold, reused or repurposed can help offset some conversion costs.
2. Cost of Labor and Equipment Removal
Removing existing sow farm infrastructure such as gestation stalls, feeders and gating can be labor intensive. Factoring in the cost of demolition and removal is essential for an accurate budget estimate.
3. Financial Costs
If a site is in reasonable condition, producers can expect to acquire and convert spaces at $150 to $250 per space, depending on the purchase price of the farm.
In contrast, building a new wean-to-finish barn, including land, costs $450 to $550 per space. This substantial cost difference makes repurposing an existing site an attractive financial option if the farm can be efficiently converted with minimal additional investment.
Flooring type significantly impacts the feasibility of conversion. A standard gestation barn will have 60-40 slatted floors (60% slatted, 40% solid). Understanding the existing flooring will determine if additional modifications are needed.
Before making your final decision, you need to know the usability of your remaining slats and beams. With an approximate cost of $100 per space just for gating and feeders, the cost of needing to replace slats could be the determining factor of proceeding with a conversion.
The Benefits of Repurposing Sow Farms
I believe it’s in the best interest of the pork industry to convert older sow farms when feasible. By repurposing facilities, the industry ensures continued productivity, avoids unnecessary regulatory challenges and maximizes the investment already made in infrastructure.
This will also help owners avoid having regulations placed on the industry which would pose significant financial and logistical burdens on producers.
Final Thoughts
Converting a sow farm into a finishing barn is a practical, cost-effective solution that can extend the usability of existing facilities while providing significant financial advantages. However, producers must carefully evaluate permitting requirements, structural feasibility and associated costs before proceeding.
Through informed decision making and adapting to changing market conditions, the pork industry can remain agile and efficient while making the best use of available resources.
