How Much Does It Cost to Build a Hog Barn?

Do you want to start a hog farm business and you want to know the cost? If YES, here is a cost breakdown to build a hog barn and the profit margin / ROI.

In recent years, Americans have witnessed large swine finishing barns constructed by their neighbors. Some of these barns were constructed by the neighbor to farm their own pigs, and some for growing the pigs for another swine producer on a contract basis.

The motivation and reasons farmers build a barn differ by individuals. Farmers are beginning to realize that livestock production, be it private or contract production, offers a hedge against erratic grain prices and allows them to utilize labor year-round.

Why Build a Hog Barn?

Hog manure is an excellent source of crop nutrients and is another reason farmers are constructing hog barns. The value of the manure differs according to the prices of commercial fertilizer, but recent years have shown it to be $4-$6/head on most wean-to-finish barns.

Notably, the rule of thumb is that for every 1,000-head capacity a barn has, there is usually manure produced to fertilize 80 acres, so a 2,500-head barn usually will do 200 acres.

However, the hog industry has improved, and learned a lot about how to build a hog barn over the past few years. It is realistic to assume that a hog barn can now last 30-40 years. Keeping moisture and rodents out of a barn, and keeping the ventilation system in good shape is a major key to a barn’s longevity and years of profitable production.

Total Cost of Constructing a Hog Barn

The cost of constructing a hog barn has risen over the past few years, and building a barn today will probably run $300 – $310/pig space. A 2,500-head facility will run $750,000 – $800,000, turnkey. Although this is no small investment for any operation, most construction loans run 10-15 years, depending on how the loan is structured.

Note that most contract situations allow a payment schedule that meets the loan obligations and allows some return for labor, but the payoff truly is at the end of the loan.

In the united states, a lot of people that have built facilities have had little to no previous experience with swine production. However, an ideal way to venture into livestock production is to work with livestock integrators. These experts will teach you to raise hogs with the management practices that fit their situations.

One major concern is that they look for people with a solid work ethic, and a good eye for details. For producers wishing to raise their own pigs, there are a lot of sources of coaching available, starting with the veterinarians, builders, and feed suppliers they associate themselves with.

Estimated Cost Breakdown for Building a Hog Farm

First and foremost, the information presented below is not a comprehensive list but an estimate of the costs of building a hog farm from the scratch. Costs have been gathered from detailed research and the estimated costs gathered from farmers across the country.

Note that these costs may not reflect some of the out-of-pocket costs to build a hog farm not the entire cost of the project. Some costs represent material costs only and do not include installation labor.

Some costs such as plumbing and electrical installation are more difficult to quantify on a per square foot or per head basis. In addition, these Costs are for 2023 and do not account for future inflation. They also do not reflect the supply and demand cycle of the construction industry and the construction season.

Note that accurate costs can only be determined by obtaining competitive bids from suppliers and builders and should include materials, installation labor, and project management costs.
