Designing Multi-Species Livestock Housing: Layout and Ventilation

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

Key Takeaways

Zoning and Airflow Separation: Multi-species housing necessitates distinct environmental zones for each species, each equipped with independent air inlets and exhaust paths to prevent airborne pathogen transmission (e.g., Mycoplasma, Pasteurella, influenza) between groups.
Enhanced Space Allocation: Allocate a minimum of 50% more space per animal than recommended for single-species housing to mitigate stress, reduce disease pressure, and facilitate safe labor access, thereby improving overall ventilation efficacy.
Species-Specific Ventilation Rates: Ventilation systems must be designed to meet the highest heat and moisture output requirements of the most demanding species (e.g., poultry, meat birds), with rates varying significantly by species, body weight, and season (e.g., cattle: 100-150 cfm/1000 lbs in summer; pigs: 100-200 cfm/100 lbs in summer).
Disease Transmission Prevention: Implement strict biosecurity measures, including separate entrances for personnel, feed, and manure, and utilize buffer zones for changing attire and disinfecting equipment to minimize cross-contamination risks, especially for diseases like Foot and Mouth Disease affecting cloven-hoofed animals.
Redundant Systems and Monitoring: Install backup power for mechanical ventilation and critical systems (water pumps, lights), coupled with an alarm system for power failures or temperature deviations, and maintain a rigorous written ventilation check routine with seasonal adjustments and detailed record-keeping.
Manure Management Diversification: Design manure handling systems that accommodate the distinct waste characteristics of each species (e.g., pelletized for sheep, wet for cattle/pigs, litter for poultry), favoring dry scraping or skid steer removal to a central point to avoid mixing incompatible waste streams.

Planning a multi-species livestock housing design requires thinking beyond the needs of a single animal type. Mixed livestock housing layout decisions affect animal health, labor efficiency, feed storage, and your daily workflow for years to come. This guide walks you through the key decisions in multi-species barn design, from zoning and traffic flow to ventilation systems that keep every species healthy. It is written for farmers who keep two or more livestock species, agricultural educators, and anyone planning a new livestock building or retrofitting an existing one.

At a Glance

Separate species into distinct zones within one building, but share support spaces like feed storage and utility rooms.
Give each species its own air inlet and exhaust path to prevent airborne disease transfer between zones.
Design for 50 percent more space per animal than the minimum for a single species building.
Place the most sensitive species, such as young animals or poultry, downwind of larger livestock.
Plan separate entrances for people, feed, and manure handling equipment to reduce cross contamination.
Use ridge vents, side wall curtains, or tunnel ventilation matched to the species with the highest heat and moisture output.
Install backup ventilation that runs on generator power and sounds an alarm if the main system fails.
Keep a written ventilation check routine for each season and record any changes you make.

Understanding the Core Challenges of Multi-Species Housing

Keeping multiple species under one roof creates efficiencies in land use, feed storage, and labor. A single barn can house sheep and cattle, or pigs and poultry, with shared manure handling and a common feed alley. However, the same building must serve animals with different temperature tolerances, airflow needs, and disease susceptibilities. The design must manage these differences rather than forcing all species into one environmental standard.

Why Species Differ in Housing Needs

Each livestock species evolved in different climates and has different physiological responses to heat, cold, drafts, and humidity. Cattle tolerate cold well but suffer in heat and humidity. Pigs are sensitive to heat but can handle cold if given dry bedding and draft protection. Sheep handle cold and wind better than most species but are prone to respiratory issues in damp, poorly ventilated buildings. Poultry, especially meat birds, produce large amounts of heat and moisture and need high ventilation rates to stay healthy.

These differences matter most in a shared building because the ventilation rate that suits one species may harm another. A barn ventilated for cattle in winter may have too much airflow for young lambs or chicks. A building designed for poultry summer ventilation may create dangerous drafts for calves. The solution is not to find one compromise setting but to design separate environmental zones with independent controls.

Disease Transmission Between Species

Some diseases pass between livestock species. Mycoplasma, pasteurella, and certain strains of influenza can move between pigs, poultry, and cattle. Internal parasites often have preferred hosts but some, like certain coccidia species, can infect multiple animal types. Foot and mouth disease affects all cloven hoofed animals. Avian influenza can spread from wild birds to poultry and in rare cases to pigs.

A multi-species barn concentrates animals in one footprint. If the ventilation system recirculates air from one species zone to another, pathogens can travel on dust particles and moisture droplets. The layout must prevent air from one species zone from entering another species zone. This is the single most important design rule for mixed livestock housing layout.

Manure and Waste Handling Conflicts

Manure consistency and volume differ by species. Cattle and pigs produce wet, high volume manure. Sheep and goats produce drier pelletized waste. Poultry produce semi dry litter with high nitrogen content. A manure handling system designed for one species may fail with another. For example, a flush system for cattle will not work well for a sheep zone with deep bedding. A belt system for poultry cannot handle cattle manure.

Plan separate manure removal routes for each species or design a system that can handle the full range of waste. Most multi-species barns work best with dry scraping or skid steer removal from each zone to a central collection point. This keeps the system simple and avoids mixing waste streams that may have different composting or spreading requirements.

Planning the Layout for Mixed Livestock Housing

The layout of a multi-species barn determines how easily you can manage the animals, move feed, remove manure, and control disease. A good layout separates the building into functional zones while keeping the overall footprint efficient.

Zoning Principles for Multi-Species Barn Design

Divide the barn into species zones, a common service area, and a buffer zone. The species zones hold the animals. The service area holds feed storage, utility rooms, and equipment parking. The buffer zone is a transition space between the service area and the animal areas where you can change boots, wash hands, and disinfect equipment.

Place the service area at one end of the barn or along one side. This keeps feed and equipment movement away from the animal zones. The buffer zone sits between the service area and each species zone. In a well designed barn, you never walk directly from a feed room into an animal pen without passing through the buffer.

Within each species zone, arrange pens or stalls to match the natural behavior of the animal. Cattle do best in groups with access to an outside lot. Sheep prefer smaller groups with protection from wind. Pigs need separate areas for feeding, sleeping, and dunging. Poultry need litter areas and elevated perches or nests depending on the production system.

Traffic Flow and Separation

Map every movement pattern in the barn before you pour concrete or set posts. People move from the office to each species zone. Feed moves from storage to each feeding area. Manure moves from each pen to the collection point. Bedding moves from storage to each pen. Sick animals move to a hospital area. Dead animals move to a removal area.

Each of these movements should have a defined path that does not cross other paths unnecessarily. The feed path should not cross the manure path. The people path should not force you to walk through a pig pen to reach the sheep. The sick animal path should be separate from the healthy animal path.

In practical terms, this means designing a central feed alley with feed storage at one end and species zones on either side. Manure removal happens from the opposite side of each species zone. The hospital area sits at the far end of the barn, away from the main traffic flow. This arrangement keeps clean and dirty activities separated.

Space Allocation by Species

Each species needs a minimum amount of floor space, and multi-species housing should exceed those minimums by a significant margin. The extra space reduces stress, lowers disease pressure, and gives you room to work safely around the animals.

For cattle, allow 40 to 60 square feet per adult animal in a bedded pack system, more if the animals are large breeds. For sheep, allow 12 to 16 square feet per ewe in a group pen, and 20 square feet for a ewe with lambs. For goats, allow 15 to 20 square feet per adult. For pigs, allow 20 to 30 square feet per finishing pig in a group pen. For poultry, allow 1 to 2 square feet per bird for meat birds and 3 to 4 square feet per laying hen.

These figures are starting points. Add 50 percent more space in a multi-species building because the animals cannot be moved to an outside lot as easily and because you need room for cleaning and equipment access. More space also improves ventilation performance because it reduces the animal density and the amount of moisture produced per cubic foot of building volume.

Feed Storage and Feeding Areas

Feed storage should be central to the building but isolated from the animal zones. A feed room with a concrete floor, rodent proof walls, and a sealed door keeps feed clean and reduces pest problems. Store each species feed in separate bins or on separate pallets with clear labeling. Cross feeding is a common mistake in multi-species barns and can cause serious health problems. For example, cattle feed with added copper is toxic to sheep, and poultry feed is dangerous for horses and can cause kidney damage in other species.

Feeding areas within each species zone should be designed for the species. Cattle and sheep can share a similar feed bunk design if the bunk height matches the smaller species. Pigs need a different feeder design that prevents rooting and waste. Poultry need feeders that keep feed clean and dry. In a multi-species barn, you cannot use one universal feeder for all zones.

Place waterers in each species zone with enough capacity for the hottest day. A dairy cow drinks 20 to 30 gallons per day. A ewe drinks 1 to 2 gallons. A finishing pig drinks 3 to 5 gallons. A laying hen drinks about 0.3 gallons. Calculate total daily water demand for each zone and size the water lines and tanks accordingly.

Ventilation Systems for Multi-Species Buildings

Ventilation is the most critical system in a livestock building. It removes moisture, heat, dust, and harmful gases, and it brings in fresh air. In a multi-species barn, ventilation must serve the species with the most demanding requirements while protecting all others.

How Livestock Ventilation Works

A livestock building ventilation system has three jobs. It removes heat produced by the animals, removes moisture from respiration and manure, and removes gases like ammonia and carbon dioxide. Fresh air enters through inlets, moves through the animal zone, and exits through exhaust fans or natural openings.

The ventilation rate is measured in cubic feet per minute per animal or per pound of body weight. The rate changes with the season. In winter, the ventilation rate drops to the minimum needed to control moisture and gases while preserving heat. In summer, the rate increases dramatically to remove animal heat and keep the building cool.

The key to good ventilation is not just moving air, it is moving air evenly through the animal zone without creating drafts on the animals. Inlets must be positioned so incoming air mixes with warm building air before it reaches the animals. Exhaust fans must be sized and placed to create even air movement across the entire floor area.

Natural Ventilation vs Mechanical Ventilation

Natural ventilation uses wind and temperature differences to move air. It works well for cattle, sheep, and goats in most climates. These species tolerate temperature swings and drafts better than pigs and poultry. A naturally ventilated building has open side walls, ridge vents, and adjustable curtains or boards. Air enters through the side openings and exits through the ridge.

Mechanical ventilation uses fans to move air. It gives precise control over temperature and airflow, which is important for pigs and poultry. A mechanically ventilated building is sealed and uses fans to pull air through inlets. This system works in all climates but costs more to operate and requires backup power.

In a multi-species barn, you have three options. Use natural ventilation for the entire building and accept that the pigs or poultry may be less comfortable. Use mechanical ventilation for the entire building and accept higher energy costs for the cattle and sheep zones. Or use a hybrid system with natural ventilation for the larger livestock zones and mechanical ventilation for the pigs and poultry zones.

The hybrid approach usually works best. It matches the ventilation system to the species needs and keeps operating costs reasonable. The building design becomes more complex because you need two ventilation systems, but the animal health benefits justify the added cost.

Designing Separate Air Zones

Each species zone must have its own air inlet and exhaust path. This prevents air from one species zone from flowing into another. The simplest way to achieve this is to design each species zone as a separate room with its own ventilation controls.

In a naturally ventilated building, use solid partitions between species zones that extend from the floor to the roof. Each zone has its own side wall openings and its own ridge section. The partitions prevent cross flow while still allowing each zone to use natural ventilation.

In a mechanically ventilated building, each species zone has its own fans and inlets. The zones are separated by solid walls. The pressure in each zone is controlled independently. This prevents air from moving from one zone to another through doorways or cracks.

If you must have a doorway between species zones, install a self closing door and keep it closed. The door should have a weather seal to prevent air leakage. Even a small gap under a door can allow significant air movement if the pressure differs between zones.

Ventilation Rates by Species

The ventilation rate you need depends on the species, the animal size, and the season. Use these figures as a starting point for planning.

For cattle, provide 100 to 150 cubic feet per minute per 1,000 pounds of body weight in summer and 30 to 50 in winter. For sheep and goats, provide 50 to 75 cubic feet per minute per adult in summer and 15 to 25 in winter. For pigs, provide 100 to 200 cubic feet per minute per 100 pounds of body weight in summer and 10 to 20 in winter. For poultry, provide 1 to 4 cubic feet per minute per pound of body weight in summer and 0.3 to 1 in winter.

These rates are minimums. In hot weather, you may need to double or triple the summer rates to keep animals comfortable. In winter, you need enough ventilation to remove moisture but not so much that the building becomes cold and drafty.

The species with the highest ventilation requirement drives the total building airflow. If you house cattle and poultry in the same building, the poultry ventilation rate will be much higher per pound of animal. The building must be designed to move that much air, even if the cattle zone uses only a fraction of it.

Managing Temperature Differences

Different species have different comfort zones. Cattle are comfortable between 25 and 65 degrees Fahrenheit depending on breed and coat. Sheep are comfortable between 30 and 70 degrees. Pigs need 60 to 75 degrees for optimal growth. Poultry need 65 to 75 degrees for layers and 70 to 80 for young meat birds.

In a multi-species barn, you cannot keep the entire building at one temperature. Each zone must have its own temperature control. In a naturally ventilated building, you adjust the side wall openings for each zone. In a mechanically ventilated building, each zone has its own thermostat and fans.

The most challenging time is winter, when the pigs and poultry need warmth but the cattle and sheep need fresh air. If you ventilate the whole building at the pig rate, the cattle zone becomes too warm and humid. If you ventilate at the cattle rate, the pig zone becomes too cold. Separate zones with independent controls solve this problem.

Heating may be needed in the pig and poultry zones during cold weather. Radiant heaters or forced air heaters sized for those zones keep the temperature in the comfort range. The cattle and sheep zones typically do not need supplemental heat if they have dry bedding and draft protection.

Humidity Control

Moisture is the biggest ventilation challenge in winter. Animals exhale moisture, and manure adds more. If ventilation does not remove this moisture, the building becomes damp, condensation forms on walls and ceilings, and respiratory disease risk rises.

The target relative humidity in a livestock building is 50 to 70 percent. Above 80 percent, the air feels damp and disease pressure increases. Below 40 percent, dust becomes a problem and respiratory irritation increases.

To control humidity, you need enough winter ventilation to remove moisture. The minimum winter ventilation rate is usually set by moisture removal, not by temperature. A simple rule is to ventilate enough that the building air does not feel stuffy or smell strongly of ammonia.

Condensation on walls and ceilings indicates insufficient ventilation. If you see water running down the walls or dripping from the roof, increase the ventilation rate or improve air mixing. Insulation helps reduce condensation by keeping interior surfaces closer to room temperature.

Step by Step Guide to Designing Your Multi-Species Barn

Follow these steps in order to create a multi-species barn design that works.

Step 1: Inventory Your Species and Animal Numbers

Write down every species you plan to house and the number of animals in each group. Include the expected weight range for each group. This determines the floor space, ventilation rate, and feed storage needs. If you plan to expand, add the expansion numbers to your calculations now, not later. Retrofitting a barn for more animals is more expensive than building the extra space in the first place.

Step 2: Calculate Space Requirements

Use the space figures from the earlier section and add 50 percent for the multi-species margin. For each species group, multiply the number of animals by the per animal space to get the total floor area for that zone. Add the service area, buffer zone, feed storage, and aisle space to get the total building footprint.

Step 3: Map Traffic Patterns

Draw a simple floor plan on graph paper or use a design program. Mark the locations of the service area, each species zone, and the buffer zones. Draw arrows for people movement, feed movement, and manure movement. Adjust the layout until the arrows do not cross in ways that create contamination risk.

Step 4: Position the Ventilation System

For each species zone, decide whether it uses natural or mechanical ventilation. Mark the inlet locations and exhaust locations on your floor plan. Make sure each zone has independent airflow control. If you are using mechanical ventilation, calculate the fan capacity for each zone using the ventilation rates from the earlier section.

Step 5: Design the Manure System

Choose a manure removal method for each species zone. Deep bedding works well for cattle, sheep, and goats. Scraping works for pigs and cattle on solid floors. Belt systems or litter removal work for poultry. Plan the removal route from each zone to the collection point. Make sure the route does not pass through feed storage or the buffer zone.

Step 6: Plan the Utility Infrastructure

Mark the locations of water lines, electrical outlets, and lighting. Water lines should reach every species zone with enough capacity for peak demand. Electrical outlets need to be near each ventilation fan and in each work area. Lighting should provide enough illumination for daily chores and for nighttime checks.

Step 7: Build in Redundancy

Every mechanical system needs a backup. Install a generator that can power the ventilation fans, water pumps, and lights. Set up an alarm system that alerts you if the temperature in any zone goes outside the acceptable range or if the power fails. Test the generator monthly and keep fuel on hand.

Common Mistakes in Multi-Species Livestock Housing Design

Avoid these frequent errors when planning your barn.

Mixing Air Between Zones

The most common mistake is designing a building where air from one species zone flows into another. This happens when the building has an open ridge that runs the full length, or when the side walls are open with no partitions. Airborne pathogens travel with the air, and a disease outbreak in one species zone can quickly spread to others.

Fix this by installing solid partitions between zones that extend from the floor to the roof plane. Each zone must have its own air inlet and exhaust path. In a naturally ventilated building, this means separate ridge sections and separate side wall openings for each zone.

Undersizing the Ventilation System

Many multi-species barns are built with the ventilation system sized for the average of all species, not the most demanding species. The result is that the pigs or poultry are always too hot, or the building is too humid in winter. The ventilation system must be sized for the species with the highest heat and moisture production.

Calculate the ventilation rate for each species zone separately and then add them together for the total building capacity. If you cannot afford the full capacity, reduce the number of animals in the most demanding species rather than undersizing the fans.

Ignoring Winter Ventilation

Some farmers close the building up tight in winter to keep the animals warm. This traps moisture and ammonia, which damages the animals respiratory systems and increases disease. Even in the coldest weather, you need some ventilation to remove moisture and gases.

The minimum winter ventilation rate is typically 10 to 20 percent of the summer rate. Use a small fan or a controlled inlet to provide this minimum airflow. Adjust the rate based on humidity and air quality rather than on temperature alone.

Poor Drainage Around the Building

Water pooling around the foundation can seep into the building and keep the floor damp. Damp floors increase disease pressure and make bedding management difficult. Grade the ground around the building to slope away from the foundation. Install gutters and downspouts to carry roof water away from the building.

Cross Contamination at the Feed Room

A feed room that opens directly into multiple species zones invites cross feeding. A worker carrying cattle feed can easily dump it into the sheep feeder if the bags are not clearly labeled or if the feeders look similar. Store each species feed in a separate area with color coded containers and clear signs. Never use the same scoop or bucket for different species feeds.

Decision Thresholds for Multi-Species Housing

Knowing when to build a new barn, retrofit an existing one, or abandon a multi-species plan can save you money and frustration.

When to Build New

Build a new barn when your existing building cannot provide separate air zones for each species. Retrofitting ventilation separation into an open pole barn is difficult and often incomplete. If the existing building has a continuous ridge and open interior, the cost of adding full height partitions and separate ventilation systems may approach the cost of new construction.

Build new when the existing building is structurally unsound or when the floor plan does not support the traffic patterns you need. A building that forces feed and manure to share the same aisle will never work well, no matter how much you remodel.

When to Retrofit

Retrofit an existing building when the structure is sound and the floor plan can be adjusted with interior partitions. If the building has a clear span interior with no load bearing walls in the way, you can install partitions and separate ventilation systems at a reasonable cost.

Retrofit when you are adding a new species to an existing single species barn. Install a full height partition to separate the new species zone, add independent ventilation, and create a separate entrance if possible. This is less expensive than building a new barn and can work well if done carefully.

When to Keep Species in Separate Buildings

Consider separate buildings when the species have very different environmental needs. If you want to raise poultry and cattle, the poultry need warm, draft free conditions while the cattle need cool, well ventilated space. Housing them in one building forces you to compromise on both.

Separate buildings also make sense when you have enough land and the buildings can be placed far enough apart to prevent disease spread. The distance between buildings reduces the risk of airborne transmission and gives you more flexibility in managing each species.

Monitoring and Recordkeeping

A multi-species barn requires regular monitoring to keep all species healthy and the systems working properly.

Daily Checks

Walk through each species zone at least once a day. Look at the animals for signs of respiratory distress, which include coughing, nasal discharge, rapid breathing, and open mouth breathing. Check the bedding for wet spots and soiled areas. Sniff for ammonia, which indicates inadequate ventilation. Look at the walls and ceiling for condensation.

Check the ventilation system each day. Confirm that fans are running, inlets are open to the correct position, and curtains are adjusted for the weather. Listen for unusual noises from fans or belts. Check the temperature in each zone and compare it to the target range for the species.

Weekly Checks

Clean and inspect the ventilation fans each week. Remove dust from the blades and guards. Check the belts for wear and the motors for overheating. Clean the inlets to make sure they are not blocked by dust, cobwebs, or nesting birds.

Check the water system for leaks and make sure all waterers are working. Test the backup generator and run it under load for at least 15 minutes. Check the alarm system by testing each sensor.

Monthly Checks

Inspect the building for structural damage, roof leaks, and gaps in the partitions. Seal any air leaks between species zones. Check the insulation for damage from rodents or moisture. Inspect the electrical system for loose connections or signs of overheating.

Review your ventilation settings against the seasonal needs. As the weather changes, adjust the inlet openings, fan settings, and curtain positions. Record any changes you make so you can track what works.

Recordkeeping

Keep a simple log for each species zone. Record the temperature, humidity, and ventilation settings. Note any animal health problems and the treatment given. Record feed consumption and water use. These records help you spot trends and identify problems before they become serious.

Record any equipment failures and repairs. Note the date, the problem, and the fix. This helps you plan maintenance and replace aging equipment before it fails.

When to Call a Veterinarian or Extension Agent

Do not wait until a problem is severe to seek professional help. Early intervention saves money and prevents disease spread.

Call a Veterinarian When

Call a veterinarian if you see signs of respiratory disease in any species zone. Coughing, nasal discharge, difficulty breathing, or sudden death require immediate attention. Respiratory disease can spread quickly through a multi-species barn, and some diseases move between species.

Call if you see a drop in feed or water consumption, a change in manure consistency, or a sudden change in behavior. These can be early signs of disease or environmental stress. A veterinarian can help you determine whether the problem is infectious or related to the housing conditions.

Call if you need help designing a vaccination program or a biosecurity plan. A veterinarian who knows your operation can tailor recommendations to your specific situation.

Call an Extension Agent When

Call your local extension agent if you are planning a new barn or major renovation. Extension agents can review your plans and point out problems before you build. They can also help you calculate ventilation rates, space requirements, and manure storage needs.

Call if you are seeing chronic health problems that do not respond to treatment. Chronic respiratory issues, poor growth, or high mortality can be caused by ventilation problems, stocking density, or nutritional issues. An extension agent can help you evaluate the building environment and management practices.

Call if you need help with manure management, nutrient planning, or regulatory compliance. Extension agents have access to resources and can help you navigate local requirements.

Frequently Asked Questions

Can I house goats and chickens together in the same barn?

Yes, but they need separate zones within the barn. Goats produce more moisture and ammonia than chickens, and chickens are more sensitive to drafts. The chicken zone needs warmer temperatures and higher ventilation rates per pound of animal. A solid partition between the zones prevents air mixing and disease spread. Chickens can also carry diseases that affect goats, so keeping them separate reduces risk.

How much extra space do I need for multi-species housing?

Plan for 50 percent more space per animal than the minimum for a single species building. The extra space reduces animal stress, improves ventilation performance, and gives you room to work safely. It also provides a buffer if you need to temporarily separate sick animals or split groups.

What is the best ventilation system for a mixed barn with cattle and pigs?

Use a hybrid system. The cattle zone can use natural ventilation with open side walls and a ridge vent. The pig zone needs mechanical ventilation with fans and controlled inlets to maintain consistent temperatures. A solid partition between the zones keeps the air separate. This approach gives each species the environment it needs without wasting energy on the species that do not need it.

How do I prevent disease spread between species in the same building?

Separate the species zones with solid partitions that extend to the roof. Give each zone its own air inlet and exhaust path so air does not flow between zones. Use separate boots and tools for each zone, or disinfect between zones. Keep feed separate and labeled for each species. Place the most sensitive species downwind of larger livestock. Establish a hospital area for sick animals that is separate from all healthy animal zones.

Do I need a backup generator for my livestock barn?

Yes, if you have any mechanically ventilated zones. Pigs and poultry can die within hours if ventilation stops during hot weather. Even naturally ventilated buildings benefit from a backup power source for lights, water pumps, and alarms. Size the generator to run all critical systems and test it monthly.

Can I use one manure handling system for all species?

It depends on the system. Deep bedding works for cattle, sheep, goats, and pigs if you manage it correctly. A flush system works for cattle and pigs but not for sheep or goats on deep bedding. Poultry litter is usually removed separately because it is dry and high in nitrogen. In most multi-species barns, a combination of approaches works best, with each zone using a method suited to the species.

How do I handle the temperature differences between species in winter?

Give each species zone independent temperature control. The cattle and sheep zones can run cooler with natural ventilation. The pig and poultry zones need supplemental heat and controlled ventilation to maintain their target temperatures. The solid partition between zones keeps the temperature differences manageable. Do not try to heat the entire building to the warmest species requirement, this wastes energy and makes the cattle and sheep uncomfortable.

What should I do if I already have a single species barn and want to add another species?

Start by evaluating the existing ventilation system. If the barn has a continuous ridge and open interior, you will need to install a full height partition and separate ventilation for the new zone. This is possible in many pole barns but requires careful planning. If the barn cannot be modified to provide separate air zones, build a separate building for the new species.
