Pig Housing Systems: Comparing Pasture, Hoop, and Barn

By Dr. Zubair Khalid, DVM, MS, PhD · 2026-08-14

Key Takeaways

• Pasture systems offer the lowest initial capital outlay and natural manure distribution, but demand high labor, require significant land, and present higher biosecurity risks due to exposure to wildlife and soil-borne pathogens, impacting disease management strategies.
• Hoop barns represent a moderate-cost alternative, utilizing deep bedding for manure absorption and composting, offering a balance between shelter and environmental enrichment, though requiring consistent bedding management and presenting moderate biosecurity risks.
• Confinement barns provide the highest level of environmental control and biosecurity, leading to superior feed efficiency and growth rates, but incur the highest capital costs and necessitate sophisticated management of ventilation, manure handling systems (liquid or pit), and emergency power.
• Feed conversion ratios are generally poorer in pasture systems (4.0-4.5 lbs feed/lb gain) due to energy expenditure on thermoregulation and activity, improve in hoop barns (3.2-3.8 lbs feed/lb gain) with partial environmental control, and are optimal in confinement (2.8-3.2 lbs feed/lb gain) due to precise climate control.
• Disease management varies significantly: pasture pigs are susceptible to parasites and wildlife-borne diseases, hoop barns require careful bedding management to mitigate pathogen buildup, and confinement barns necessitate stringent biosecurity protocols to prevent introduction via personnel and equipment.

Choosing the right housing system is one of the most consequential decisions you will make as a pig farmer. The structure you select affects daily labor, feed efficiency, animal health, manure management, and your initial capital outlay. It also shapes how you manage temperature extremes, predators, and biosecurity risks. This guide compares the three dominant pig housing options available to small and mid-scale producers: pasture lots, hoop barns, and confinement barns. It is written for farmers who are planning a new operation, expanding an existing one, or reconsidering their current setup. You will learn how each system works, what it costs to build and operate, which management practices keep pigs healthy in each environment, and how to decide which system fits your land, climate, and market.

At a Glance

Understanding the Three Systems

Pig housing systems fall on a continuum from extensive to intensive management. Pasture systems give pigs outdoor access with minimal structures. Hoop barns provide a sheltered environment with deep bedding and outdoor access. Confinement barns keep pigs indoors with climate control and fully slatted or solid floors. Each system changes how you manage feed, water, waste, and health. There is no single best system. The right choice depends on your climate, available land, labor, capital, and target market.

Pasture Pig Housing

Pasture systems are the oldest form of pig keeping. Pigs live outdoors in fenced paddocks with access to shelters such as A-frames, huts, or portable tents. The pigs root, graze, and forage while you move them to fresh ground on a schedule. This system works well for small herds and for farmers who market pasture-raised pork at a premium.

The main advantage of pasture is low capital cost. You can start with portable shelters, electric fencing, and water lines for a few thousand dollars. Pasture also spreads manure naturally across the land, which builds soil fertility over time. Pigs on pasture have more space to express natural behaviors, which can reduce stress and improve meat quality in some markets.

The trade-offs are significant. Pasture pigs require more labor for daily feeding, moving shelters, checking fences, and managing water. You need enough land to rotate paddocks and prevent soil damage. Predators, weather extremes, and parasites are constant concerns. Pasture also makes biosecurity harder because pigs contact wildlife, wild birds, and soil-borne pathogens.

Hoop Barns

Hoop barns are a middle ground between pasture and confinement. The building consists of a steel or PVC frame covered with a polyethylene tarp or fabric. The structure has no solid side walls. Instead, it has raised side curtains that can open for ventilation or close for weather protection. The floor is a solid pad, usually concrete or gravel, covered with deep bedding such as straw, cornstalks, or wood shavings.

Hoop barns were developed at Iowa State University in the 1990s as a lower-cost alternative to confinement buildings. They work well for finishing pigs, gestating sows, and growing gilts. The deep bedding absorbs manure, controls odors, and provides a composting process inside the building. When the barn is empty, you remove the bedding and apply it to cropland.

The main advantage of hoop barns is lower construction cost than confinement. A hoop barn can cost 50 to 70 percent less per pig space than a fully slatted confinement building. The deep bedding system reduces the need for liquid manure storage and handling. Hoop barns also give pigs more space and environmental enrichment than confinement, which appeals to certain markets.

The trade-offs include higher bedding costs and labor for bedding management. Hoop barns do not provide full temperature control, so pigs experience more seasonal temperature swings. Ventilation requires careful management of the side curtains to balance air quality and temperature. In very cold or very hot climates, pigs may need supplemental heat or cooling.

Confinement Barns

Confinement barns are fully enclosed buildings with climate control. They typically have slatted floors over a manure pit or a flush system. The barns use mechanical ventilation, heaters, and sometimes evaporative cooling to maintain a consistent temperature. Pigs live in pens with concrete or slatted floors, and you control feed and water delivery automatically.

The main advantage of confinement is efficiency. You can raise more pigs per square foot, with less labor per pig. Climate control reduces temperature stress, which improves feed conversion and growth rates. The controlled environment also makes biosecurity easier because you limit contact with wildlife and outside contamination. Confinement systems are the standard for large commercial production.

The trade-offs are high capital cost and management intensity. A confinement barn with full climate control can cost two to three times more per pig space than a hoop barn. Manure management requires a liquid storage system and a plan for application. The controlled environment also means you must manage ventilation carefully to prevent respiratory disease from ammonia and dust. If the power goes out or a fan fails, pigs can die quickly from heat or poor air quality.

Comparing Capital Costs

Your budget will drive many housing decisions. The cost per pig space varies widely depending on the system, the level of automation, and your local construction costs.

Pasture System Costs

Pasture systems have the lowest startup costs. Your main expenses are fencing, shelters, water lines, and feeders. A good electric fence setup for a pasture paddock costs roughly $500 to $1,500 per acre depending on the type of charger, wire, and posts you choose. Portable shelters range from $300 for a simple A-frame to $2,000 for a well-insulated hut with a floor. Water systems with frost-free hydrants or heated waterers add another $500 to $2,000 depending on how far you run the lines.

You also need to account for land. Pasture systems require 4 to 8 sows per acre for breeding herds, or 20 to 40 growing pigs per acre depending on rotation intensity and soil type. If you do not own enough land, you must factor in lease costs. Some farmers use pasture in rotation with row crops, which spreads the land cost across multiple enterprises.

Hoop Barn Costs

Hoop barns cost significantly less than confinement but more than pasture. A basic hoop barn for finishing pigs runs $15 to $25 per square foot installed. A 30 by 72 foot hoop barn, which houses about 200 finishing pigs, costs $32,000 to $54,000 for the structure alone. You also need a concrete or gravel pad, which adds $5,000 to $15,000 depending on the size and site preparation. Water lines, feeders, and fencing inside the barn add another $3,000 to $8,000.

The total cost per finishing pig space in a hoop barn typically runs $150 to $300. This compares favorably to confinement, which often runs $400 to $700 per pig space. The lower cost comes from the simpler structure, no slatted floors, and no mechanical ventilation system.

Confinement Barn Costs

Confinement barns are the most expensive to build. A fully slatted, climate-controlled finishing barn costs $50 to $80 per square foot installed. A barn for 1,000 finishing pigs at 8 square feet per pig needs 8,000 square feet of floor space. At $60 per square foot, that barn costs $480,000. Add in the manure pit, ventilation equipment, feeding system, and site work, and the total can exceed $600,000.

The cost per pig space in a confinement barn ranges from $400 to $700 for finishing pigs. Sow barns with individual stalls and farrowing rooms cost more, often $1,000 to $1,500 per sow space when you include the specialized equipment.

Your financing options also differ. Confinement barns are easier to finance because they have a longer useful life and are considered real property. Hoop barns and pasture equipment are often financed as equipment or operating loans. Talk to your lender early about what they will finance and what down payment they require.

Labor Requirements and Daily Management

Labor is the cost that many farmers underestimate. The system you choose determines how many hours you spend each day on chores and how much of that work you can automate.

Pasture Labor

Pasture systems demand the most labor per pig. You will spend time every day checking fences, moving shelters, filling water tanks, and hauling feed. On a pasture system with 20 sows and their litters, plan on 2 to 4 hours of pig chores per day. During farrowing season, that time increases because you need to check sows more often.

Moving shelters and paddocks is the most labor-intensive part of pasture management. You move shelters every 3 to 14 days depending on stocking rate and forage condition. Each move requires pulling the shelter with a tractor or ATV, resetting the fence, and checking the water line. A well-designed paddock system with permanent water lines and quick-connect gates can cut this time in half.

Feeding on pasture is also manual. You fill feeders or spread grain on the ground, which takes time and can waste feed if you overfill. Some farmers use self-feeders that hold several days of feed, which reduces trips. But self-feeders are more expensive and can break down.

Hoop Barn Labor

Hoop barns require moderate labor, concentrated in bedding management and feeding. Daily chores include checking water, filling feeders, and adjusting side curtains for ventilation. Plan on 1 to 2 hours per day for a hoop barn with 200 finishing pigs.

The big labor event is bedding. You add fresh bedding every few days to keep the pack dry and absorbent. Every 2 to 4 weeks, you may need to add a significant layer of straw or shavings. When the barn is empty, you remove the entire bedding pack with a skid steer or tractor. This takes 4 to 8 hours for a 30 by 72 foot barn and produces 50 to 100 tons of composted manure.

Some farmers reduce labor by using a deep-bedding system where they add straw on top and let the bottom compost in place. This works well for finishing pigs but requires attention to moisture and ammonia levels.

Confinement Barn Labor

Confinement barns have the lowest labor per pig because you can automate feeding, watering, ventilation, and manure removal. A well-designed confinement barn for 1,000 pigs takes 1 to 2 hours per day for one person. The work is checking equipment, treating sick pigs, and monitoring the ventilation system.

The trade-off is that the labor you do have is more technical. You must understand ventilation controllers, alarm systems, feed delivery augers, and manure pumps. When something breaks, you need to fix it quickly or call a technician. A failed fan in summer or a broken heater in winter can kill pigs within hours.

You also spend time on tasks that pasture and hoop producers do not face. You must pump and agitate the manure pit, calibrate the feeding system, and clean the barn between groups. These tasks are not daily, but they require planning and equipment.

Feed Efficiency and Growth Performance

Housing affects how efficiently pigs convert feed into gain. Temperature stress, crowding, and disease pressure all influence feed conversion ratio, which is the pounds of feed needed to produce one pound of gain.

Pasture Feed Efficiency

Pasture pigs generally have worse feed conversion than barn-raised pigs because they burn energy walking, rooting, and regulating body temperature. A pasture-finishing pig may need 4.0 to 4.5 pounds of feed per pound of gain, compared to 3.0 to 3.5 in a confinement barn. The difference is smaller in mild weather and larger in extreme heat or cold.

However, pasture pigs eat some forage and root material, which reduces the amount of supplemental feed they need. The quality of pasture matters. Good pasture with clover and chicory can supply meaningful nutrition. Poor pasture with thin grass provides little more than exercise.

Pasture-raised pigs also grow more slowly. They may take 7 to 9 months to reach market weight of 250 to 280 pounds, compared to 5 to 6 months in confinement. This slower growth increases your feed cost per pig but may be offset by premium prices for pasture-raised pork.

Hoop Barn Feed Efficiency

Hoop barns provide better feed efficiency than pasture because pigs are protected from weather and spend less energy on movement. Feed conversion in a well-managed hoop barn typically runs 3.2 to 3.8 pounds of feed per pound of gain. The deep bedding provides some warmth in winter, which reduces maintenance energy needs.

The main factor affecting feed efficiency in hoop barns is temperature. In cold weather, pigs eat more to stay warm. In hot weather, they eat less and grow slower. Managing the side curtains to keep the barn comfortable is the key to good feed efficiency.

Hoop barns also allow you to use the same feed rations as confinement barns. You do not need special pasture rations or forage supplementation. This simplifies feed purchasing and formulation.

Confinement Feed Efficiency

Confinement barns have the best feed efficiency because you control the environment year-round. A well-managed confinement barn achieves feed conversion of 2.8 to 3.2 pounds of feed per pound of gain. The consistent temperature reduces stress, and the controlled environment reduces disease pressure.

The trade-off is that confinement pigs need higher-quality feed to reach their genetic potential. You cannot rely on forage or rooting to supplement the ration. Your feed costs per pig are higher, but your feed cost per pound of gain is lower.

Confinement also allows you to use phase feeding more precisely. You can adjust the ration for each growth stage and even for individual pens. This precision improves efficiency and reduces waste.

Manure Management

Manure is a valuable resource and a regulatory responsibility. The housing system you choose determines how you collect, store, and apply manure.

Pasture Manure

Pasture systems spread manure naturally across the paddock. The pigs deposit manure where they are, and it breaks down in place. This builds soil organic matter and fertility over time. A well-rotated pasture system can supply a significant portion of the nitrogen, phosphorus, and potassium that crops need.

The challenge is managing nutrient distribution. Pigs tend to concentrate manure near feeders, waterers, and shelters. You may need to move these features regularly to spread the fertility. You also need to monitor soil test results to ensure you are not over-applying nutrients in high-traffic areas.

Pasture manure can harbor parasites, especially if you keep pigs on the same ground too long. Internal parasites like roundworms and whipworms thrive in pig manure. Rotating paddocks and resting ground for 6 to 12 months between pig use helps break the parasite cycle.

Hoop Barn Manure

Hoop barns produce solid manure mixed with bedding. This is a composting system in place. The bedding absorbs urine and manure, and the microbial activity breaks it down over time. When you clean the barn, you have a nutrient-rich compost that you can apply to cropland.

The nutrient value of hoop barn manure depends on the bedding type and how long it composts. Straw-based bedding produces a drier, more stable product. Wood shavings produce a slower-composting, higher-carbon product that may tie up nitrogen temporarily in the soil.

You need a plan for storing and applying the manure. Most hoop barn operators stack the manure in a covered area or spread it directly on fields. You should soil test your fields and follow your nutrient management plan to avoid over-application.

Confinement Manure

Confinement barns produce liquid manure in a pit beneath the slatted floor. The pit stores the manure until you pump it out and apply it to fields. Liquid manure is easy to handle with pumps and tankers, and it provides readily available nutrients to crops.

The challenges are odor, storage capacity, and application timing. Liquid manure pits can produce strong odors, especially when you agitate and pump them. You need enough storage capacity to hold manure through periods when you cannot apply, such as frozen ground or saturated soils. In many states, you must follow a nutrient management plan and comply with regulations for manure application.

Deep pits under the barn are common for finishing operations. You pump the pit once or twice a year. Some operations use pull-plug systems that drain to an outside storage structure. The choice depends on your local regulations and your manure application schedule.

Temperature Management and Ventilation

Pigs are sensitive to temperature. They have limited sweat glands and struggle to cool themselves in heat. They also have little insulation against cold. The housing system determines how much you can control the temperature.

Pasture Temperature

Pasture pigs have only their shelters for temperature protection. A well-designed A-frame or hut provides shade in summer and a dry, draft-free space in winter. But the shelters do not provide active heating or cooling. Pigs must cope with the ambient temperature.

In summer, pasture pigs need access to shade and wallows. A wallow is a mud hole that helps pigs cool off. You can create a wallow by providing a shallow pool or by keeping an area wet. Without wallows, pigs can suffer heat stress, which reduces growth and can be fatal.

In winter, pasture pigs need dry bedding and protection from wind. Straw is the best bedding because it insulates well and stays dry. You also need to provide enough feed to help pigs maintain body temperature. Pregnant sows on pasture in winter may need 10 to 20 percent more feed than in mild weather.

Hoop Barn Temperature

Hoop barns provide more temperature control than pasture but less than confinement. The key is managing the side curtains. In warm weather, you roll the curtains up to maximize airflow. In cold weather, you close them to trap heat from the pigs and the bedding.

The deep bedding is a major heat source. The composting process generates heat, which can raise the barn temperature several degrees above the outside temperature in winter. This helps reduce feed costs and keeps pigs comfortable.

In summer, hoop barns can get very hot because the tarp absorbs solar radiation and the building has limited insulation. You need to open the curtains fully, provide good airflow, and consider adding fans or sprinklers. Some producers use shade cloth over the barn or paint the tarp white to reflect heat.

The critical management task is adjusting the curtains as weather changes. A hoop barn can go from too cold to too hot in a few hours. Check the forecast daily and adjust curtains accordingly.

Confinement Temperature

Confinement barns give you full temperature control. You set the thermostat and the ventilation system maintains the temperature. This consistency improves feed efficiency and reduces stress.

The ventilation system is the most important piece of equipment in a confinement barn. It must provide enough fresh air to remove moisture, ammonia, and dust while maintaining temperature. Most systems use a combination of exhaust fans and air inlets. The controller adjusts fan speed and inlet openings to match the conditions.

In winter, you add heat with gas or electric heaters. In summer, you use high-volume fans and sometimes evaporative cooling pads or sprinklers. The goal is to keep pigs in their thermoneutral zone, where they do not need to expend energy to stay warm or cool.

The risk is equipment failure. A power outage in summer can kill a barn full of pigs within hours. You need backup generators, alarm systems, and a plan for responding to emergencies. Check the ventilation system daily and test alarms regularly.

Biosecurity and Disease Management

Biosecurity is the set of practices you use to prevent disease introduction and spread. The housing system affects your biosecurity risks and the measures you can take.

Pasture Biosecurity

Pasture systems have the highest biosecurity risk. Pigs are outdoors where they can contact wildlife, wild birds, and stray animals. Feral pigs can spread African swine fever, pseudorabies, and other diseases. Wild birds can introduce influenza viruses. Rodents and flies thrive around outdoor feeding areas.

You can reduce these risks with good fencing, rodent control, and bird deterrents. Double fencing or electric fencing can keep out feral pigs. Cover feeders to reduce bird access. Keep the area around the paddock clean and free of spilled feed.

The bigger challenge is that you cannot control the environment. If a disease is in the local wildlife population, your pigs can be exposed. You need a strong vaccination program and regular health monitoring.

Hoop Barn Biosecurity

Hoop barns offer moderate biosecurity. The open sides allow some contact with wildlife and birds, but the structure provides more protection than open pasture. You can control access to the building and limit who enters.

The main biosecurity risk in hoop barns is the deep bedding. The bedding can harbor pathogens, and it is difficult to fully clean and disinfect between groups. Some producers remove all bedding and wash the pad between groups. Others use a downtime period to let the bedding compost and reduce pathogen load.

You should also manage the area around the hoop barn. Keep vegetation mowed to reduce rodent habitat. Keep feed storage clean and covered. Control access to the barn with a lockable gate.

Confinement Biosecurity

Confinement barns offer the highest level of biosecurity. You can control who enters, require showers and boot changes, and limit contact with wildlife. The closed environment makes it easier to implement strict protocols.

The main risk in confinement is the movement of people and equipment. Visitors, service technicians, and new pigs can introduce disease. You need a clear protocol for entry, including a visitor log, boot washing, and a downtime period for people who have been around other pigs.

You also need to manage the air. Confinement barns use high volumes of air, and some diseases can spread through the air over short distances. If you are in an area with high pig density, you may need to filter or treat incoming air to reduce disease risk.

Common Mistakes and How to Avoid Them

Every housing system has common pitfalls. Knowing them in advance can save you time, money, and animal loss.

Pasture System Mistakes

The most common pasture mistake is overstocking. Too many pigs on too little land destroys the sod, creates mud, and concentrates parasites. Start with fewer pigs than you think you can handle. A good rule is 4 to 6 sows per acre for breeding herds and 20 to 30 growing pigs per acre.

Another mistake is poor fence design. Pigs are strong and curious. A fence that works for cattle will not hold pigs. Use quality electric fencing with a strong charger, and check the fence daily. A dead fence is no fence.

Many pasture producers also underestimate the importance of water. Pigs need clean, fresh water at all times. In summer, a pig can drink 3 to 5 gallons per day. A water system that is too small or unreliable will hurt growth and health.

Finally, do not forget about shade. Pigs overheat quickly, and a pig without shade in summer will suffer. Provide portable shade structures or ensure your shelters are adequate for the number of pigs.

Hoop Barn Mistakes

The most common hoop barn mistake is poor bedding management. Too little bedding leads to wet, dirty pigs and ammonia buildup. Too much bedding can block ventilation and create hot spots. Add bedding regularly and monitor the pack moisture.

Another mistake is failing to manage the side curtains. Producers who set the curtains and forget them end up with pigs that are too hot or too cold. Check the forecast and adjust the curtains daily. In spring and fall, you may need to adjust them multiple times per day.

Some producers also overcrowd hoop barns. The recommended space is 8 to 10 square feet per finishing pig. Going below this reduces growth and increases the risk of tail biting and other behavioral problems.

Finally, do not ignore the manure. Hoop barns produce a lot of bedding and manure. If you do not have a plan for removal and application, the pile will grow and become a nuisance. Plan your manure management before you build.

Confinement Barn Mistakes

The most common confinement mistake is under-ventilating in winter to save heat. This leads to high ammonia, high humidity, and respiratory disease. The ventilation system must run even in cold weather to remove moisture and gases. The cost of heating the incoming air is less than the cost of treating sick pigs.

Another mistake is ignoring the alarm system. A confinement barn with a failed alarm can lose pigs in a power outage or fan failure. Test alarms weekly and have a backup generator that you test monthly.

Many producers also overcrowd confinement barns. The recommended space is 8 to 10 square feet per finishing pig. Less space reduces growth and increases aggression. Follow the space recommendations for the weight of your pigs.

Finally, do not neglect maintenance. Fans, heaters, feeders, and manure equipment need regular service. A small repair today prevents a major failure tomorrow. Keep spare parts on hand, including belts, thermostats, and sensors.

Decision Thresholds: Which System Should You Choose?

Use the following questions to guide your decision. There is no perfect system, but there is a system that fits your situation.

Choose Pasture If

You have adequate land. You need at least 1 acre for a small herd, and more for rotation. You can manage the daily labor of moving shelters and checking fences. You have a market that pays a premium for pasture-raised pork. You are comfortable with higher disease risk and slower growth. Your climate is moderate, with no extreme heat or cold. You have a small herd of 50 pigs or fewer and want to minimize capital investment.

Choose a Hoop Barn If

You want lower capital cost than confinement but better protection than pasture. You have access to affordable bedding such as straw or cornstalks. You can manage the daily curtain adjustments and periodic bedding removal. You are willing to accept some temperature variation and slower growth in extreme weather. You have a mid-size operation of 50 to 500 pigs. You want a flexible building that can also serve as a shelter for other livestock or equipment.

Choose Confinement If

You have the capital for a high-cost building. You want maximum feed efficiency and growth rates. You are in a climate with extreme temperatures. You want the highest level of biosecurity and disease control. You have the technical skills to manage ventilation, alarm systems, and manure equipment. You are producing at scale, with more than 500 finishing pigs per year. You want to minimize labor per pig and are willing to invest in automation.

Hybrid Approaches

Many farms use a combination of systems. For example, you might farrow in a confinement barn for biosecurity and temperature control, then move weaned pigs to hoop barns for finishing. Or you might keep gestating sows on pasture and move them to a hoop barn for farrowing. These hybrid systems let you match the housing to the pig's stage of life and your management strengths.

Monitoring and Recordkeeping

Whatever system you choose, you need a monitoring and recordkeeping plan. Good records help you spot problems early, track performance, and make better decisions.

What to Monitor Daily

Check your pigs at least once a day, and twice a day during extreme weather or farrowing. Look for signs of illness, injury, or distress. Check that water is flowing and clean. Check that feeders are working and not wasting feed. Note the temperature and adjust ventilation or shelter as needed.

In pasture systems, walk the fence line daily to check for damage or breaches. In hoop barns, check the bedding moisture and add fresh bedding as needed. In confinement, check the ventilation system, alarm panel, and manure pit level.

What to Record

Keep records for each group of pigs. Record the number of pigs, their average weight at placement, and the date. Track feed deliveries and calculate feed conversion at the end of each group. Record any treatments, deaths, and the cause if known. Note any environmental events such as heat waves, storms, or power outages.

Use a simple spreadsheet or a paper notebook. The goal is to have data you can compare across groups and years. At the end of each group, calculate the average daily gain, feed conversion, and mortality rate. Compare these numbers to your targets and to previous groups.

Health Monitoring

Work with your veterinarian to develop a health monitoring plan. This includes a vaccination schedule, a parasite control program, and a protocol for sick pigs. Know the normal signs of health for pigs: bright eyes, smooth coat, active behavior, and a good appetite. Learn to recognize the early signs of illness: lethargy, reduced appetite, coughing, diarrhea, or a rough coat.

When to Call a Veterinarian or Extension Agent

You should call a veterinarian when you see signs of serious illness, when pigs are dying, or when you are unsure about a diagnosis. Do not wait to see if a sick pig improves on its own. Early treatment is more effective and less costly.

Specific situations that warrant a vet call include:

• Multiple pigs sick or dying within a short period
• Pigs with high fever, severe diarrhea, or respiratory distress
• A sow that is having difficulty farrowing
• A pig with a severe injury or prolapse
• Any sudden change in appetite, behavior, or mortality

Your veterinarian can also help with herd health planning, vaccination programs, and biosecurity audits. Establish a relationship with a swine veterinarian before you have an emergency.

Your local extension agent is a valuable resource for production questions, nutrient management planning, and business decisions. Extension agents can help you design a housing system, develop a manure management plan, or connect you with other resources. They can also help you understand local regulations and permitting requirements.

Frequently Asked Questions

How many pigs can I keep per acre on pasture?

The answer depends on your soil, climate, and management intensity. A conservative stocking rate is 4 to 6 sows per acre for a breeding herd, or 20 to 30 growing pigs per acre. With intensive rotation and good pasture, you can sometimes keep more, but do not push the land too hard. Overstocked pasture turns to mud, creates parasite problems, and reduces pig growth.

What is the cheapest pig housing option to build?

Pasture systems have the lowest startup cost. You can begin with portable shelters, electric fencing, and a water system for a few thousand dollars. Hoop barns are the next cheapest, at roughly $150 to $300 per pig space. Confinement barns are the most expensive, at $400 to $700 per pig space. Remember that the cheapest to build may not be the cheapest to operate when you factor in labor and feed efficiency.

How much bedding do I need for a hoop barn?

A good rule is 10 to 15 pounds of straw per pig per week for finishing pigs. A 30 by 72 foot hoop barn with 200 pigs will use 2,000 to 3,000 pounds of straw per week. The amount varies with season, with more bedding needed in winter and less in summer. You can reduce bedding use by managing the pack carefully and removing only the top layer between groups.

Can I use a hoop barn for farrowing?

Yes, but it is more challenging than finishing. Sows need more space and a protected area for farrowing. Some producers use individual farrowing pens within a hoop barn, while others use group farrowing systems. The key is providing a clean, dry, draft-free area for the sow and piglets. You also need to manage the temperature, as newborn piglets need warmth.

Do pasture-raised pigs taste better than confinement pigs?

The taste difference is debated. Some consumers prefer pasture-raised pork because the pigs have more exercise and a more varied diet, which can affect fat quality and flavor. However, the breed, diet, and processing methods have a larger effect on taste than the housing system. If you market pasture-raised pork, focus on consistent quality and good processing, not just the housing claim.

How do I handle manure from a hoop barn?

Hoop barn manure is solid and mixed with bedding. You can apply it directly to fields with a manure spreader. The nutrient content varies, so have the manure tested before application. The best practice is to compost the manure for several months before spreading, which reduces pathogens and makes the nutrients more available to crops. Follow your nutrient management plan and local regulations.

What are the biggest health risks in each system?

Pasture pigs face higher risks from internal parasites, wildlife-borne diseases, and weather stress. Hoop barn pigs face risks from ammonia buildup, respiratory disease, and temperature swings. Confinement pigs face risks from respiratory disease, lameness from slatted floors, and equipment failure. Each system requires a different health management focus.

Do I need a building permit for a hoop barn?

Permit requirements vary by location. Some areas treat hoop barns as agricultural structures and exempt them from building permits. Others require permits, especially for larger buildings or those with concrete foundations. Check with your local planning office before you build. The cost of a permit is small compared to the cost of removing a noncompliant building.
