# Handling Facility Design for Pigs: Chutes, Crowd Pens, and Loading Ramps ## Key Takeaways - Facility design must account for pig vision and behavior, utilizing solid sides (at least 4 feet high) and even lighting to minimize distractions and shadows, thereby promoting calm movement. - Chute width is critical for efficient movement: 16-24 inches for market hogs and 12-16 inches for weaned pigs, preventing turning around and reducing balking. - Crowd pens should be round or rounded (6-10 ft radius) to encourage forward movement, holding only 5-8 pigs to prevent fighting and utilize the following instinct. - Loading ramp angles should not exceed 20 degrees (ideally 15 degrees or less) to prevent balking and reduce injury risk, with a smooth, gap-free transition to the truck bed. - Proper handling facilities reduce shrink by 1% or more and save labor time, paying for themselves through reduced weight loss and fewer injuries to pigs and personnel. - Biosecurity is paramount; design the facility to prevent truck drivers from entering clean farm areas, with loading ramps extending to the truck and drivers operating gates remotely. --- Moving pigs is one of the most frequent and stressful tasks on any farm. Whether you are weaning 50 piglets or shipping 200 market hogs, the way you design your handling facilities determines how quickly the job gets done, how safe your workers remain, and how much weight the pigs lose before they leave your care. Poor handling facilities cause bruising, stress, injuries to both pigs and people, and they cost you money at sale time. This guide covers the full planning process for [pig handling](/knowledge/animal-farming/swine/pig-handling-transport-welfare-best-practices) facility design. It walks through the principles of pig vision and behavior that drive every design decision, then provides specific dimensions and layouts for crowd pens, straight chutes, turnarounds, and loading ramps. You will also find guidance on site selection, materials, biosecurity, recordkeeping, and common mistakes to avoid. This article is written for farmers who are building a new facility, renovating an existing one, or simply trying to understand why their current setup is not working. It is equally useful for farm managers, extension educators, and agricultural students who need a practical reference on swine handling systems. ## At a Glance - Pigs see in limited color and have a wide field of vision, so solid sides, even lighting, and no shadows are essential for calm movement. - A single-file chute should be 16 to 24 inches wide for market pigs and 12 to 16 inches wide for weaned pigs, depending on the size of your animals. - Crowd pens should hold no more than 5 to 8 pigs at a time and should be round or rounded with a radius of 6 to 10 feet. - The recommended loading ramp angle is 20 degrees or less. Anything steeper causes pigs to balk and increases the risk of injury. - A proper handling facility pays for itself by reducing shrink, bruising, and labor time. Even a modest setup can save you 30 minutes per load and reduce weight loss by 1 percent or more. - Solid fencing at least 4 feet high prevents pigs from seeing distractions outside the handling area. - Never mix unfamiliar pigs in a crowd pen. Mixing causes fighting and makes movement worse. - Keep records of loading times, shrink percentages, and any injuries so you can measure improvements after you build or renovate. ## Why Pigs Behave the Way They Do in Handling Facilities Before you draw a single line on paper, you need to understand how a pig sees and reacts to the world. Every design decision you make either works with the pig's natural instincts or fights against them. Pigs that are calm and moving willingly are easier to handle, safer for workers, and less likely to arrive at their destination bruised or stressed. Pigs have monocular vision on the sides of their heads and a small area of binocular vision in front. This gives them a wide field of view, nearly 310 degrees, but it also means they have a blind spot directly behind them. This is why a pig will often stop and turn its head to look at you when you are behind it. It is not being stubborn. It is trying to see what is there. Pigs are also dichromats, which means they see in two colors rather than three. They can distinguish blue and yellow but have trouble telling red and green apart. This matters for facility design because a red gate against a green background may look like a solid wall to a pig, while a sudden change in light intensity can look like a drop-off or an obstacle. Pigs are highly sensitive to contrast, so a dark shadow across a light floor can stop an entire group of animals. The pig's natural tendency when frightened is to turn back toward where it came from. This is called the flight zone and point of balance concept. When you work behind the point of balance, the pig moves forward. When you work in front of it, the pig stops or backs up. In a well-designed facility, you rarely need to touch a pig at all. The facility itself does the work by guiding the animal through a series of one-way decisions. Pigs also have a strong following instinct. If one pig moves forward confidently, the others will follow. This is why a well-designed crowd pen and chute that allow the lead pig to keep moving are so important. Once the lead pig stops and turns around, the whole group stops and the job becomes harder. Finally, pigs have excellent memories. If a pig has a bad experience in a chute or on a ramp, it will remember that for months. A facility that causes pain, loud noises, or sudden movements will make every future load more difficult. A facility that is quiet, consistent, and predictable will make every future load easier. ## Site Selection and Layout Planning The first decision you make is where to put the handling facility. This choice affects everything else, including cost, biosecurity, and daily workflow. The ideal location is close to the barns but not so close that the noise and activity of loading disrupt the rest of the herd. You also want the loading area positioned so that trucks can approach and leave without backing through the main farm traffic lanes. Start by thinking about the flow of pigs. Pigs should move from their home pens into an alley, then into a crowd pen, then into a chute, and finally onto the truck. Each step should be a natural progression with no sharp turns or sudden changes in direction. The fewer turns, the better. Each 90 degree turn is a place where pigs can balk, bunch up, or turn back. Consider the direction of the sun. In the Northern Hemisphere, a south-facing loading ramp will have the sun in the pigs' eyes during midday loads. An east or west facing ramp will have low sun angles in the morning or evening. The best approach is to orient the ramp so that the sun is behind the pigs as they load, or to build a roof or shade structure that eliminates direct sun in the loading area. Wind direction also matters. Pigs will balk if they are walking into a strong headwind, especially if the wind is carrying unfamiliar odors from the truck or from off the farm. Position the loading area so that prevailing winds blow across the chute rather than down it. If that is not possible, build a windbreak or solid wall on the windward side. Drainage is another critical factor. The area around the loading ramp and crowd pen will get wet from urine, manure, and rain. Poor drainage creates mud, which makes footing slippery and pigs reluctant to move. The entire handling area should have a slight slope of 1 to 2 percent away from the buildings and toward a drainage system that carries effluent to a proper storage facility. Concrete aprons around the ramp and chute make cleaning much easier. Biosecurity is a growing concern for every pig farm. Your handling facility should be designed so that the truck driver never has to enter the farm's clean area. The loading ramp should extend to the truck with a solid connection, and the driver should be able to operate the truck gate from the cab or from a designated dirty-side walkway. If you use a livestock hauler, talk to them about their biosecurity protocols and what they need from your facility to keep things clean. Finally, think about future expansion. A handling facility that works for 200 sows may be too small for 400 sows. Build the crowd pens and alleys with enough capacity to handle the largest group you might have in the next 10 years. It is much cheaper to build a slightly larger facility now than to tear out and rebuild later. ## The Crowd Pen The crowd pen is the area where pigs gather before they enter the single-file chute. It is the most important part of the handling system because it is where most problems start. A poorly designed crowd pen creates stress, bunching, and refusal to enter the chute. A well-designed crowd pen makes the pigs feel safe and encourages them to move forward on their own. The crowd pen should be round or semicircular in shape. Pigs naturally follow the curve of a round pen and will keep moving along the wall toward the chute entrance. A square or rectangular pen has corners where pigs can bunch up and turn around. If you already have a square pen, you can improve it by adding a curved insert or a solid panel that creates a rounded corner at the chute entrance. The recommended radius for a crowd pen is 6 to 10 feet for market hogs. This gives enough space for 5 to 8 pigs at a time without letting them turn around easily. The pen should hold no more than one load group at a time. Overcrowding the crowd pen causes fighting and stress, while underfilling it reduces the natural following instinct that helps move pigs forward. The crowd pen needs a solid gate that can be closed behind the pigs once they are inside. This gate should be curved or angled so that it pushes the pigs toward the chute entrance as it closes. A straight gate tends to push pigs into the corners. The gate should have a latch that can be operated from outside the pen so the handler does not have to climb in with the pigs. The floor of the crowd pen should be solid concrete with a rough broom finish for traction. Slatted floors can work, but pigs sometimes balk at the gaps and the visibility of the pit below. If you use slats, make sure the gaps are narrow enough that a pig's hoof cannot get caught. The floor should be slightly sloped toward the chute entrance, about 1 to 2 percent, so that pigs naturally walk downhill into the chute. Lighting in the crowd pen needs to be even and shadow-free. A single bright light at the chute entrance will draw pigs forward, but any shadows or dark spots will make them hesitate. If the facility is indoors, use diffused lighting that spreads evenly across the pen. If it is outdoors, position the pen so that the sun is behind the pigs as they move toward the chute. The chute entrance is the most critical point in the crowd pen. The entrance should be funnel-shaped, narrowing gradually from the full width of the pen down to the width of the chute. This funnel shape encourages pigs to enter one at a time without a visible transition point. Some facilities use a "gate and funnel" system where a sliding gate narrows the pen progressively as pigs enter the chute, reducing the need for the handler to push from behind. ## The Single-File Chute The single-file chute is the narrow passage that moves pigs from the crowd pen to the loading ramp or to the processing area. It is called single-file because it is designed to hold pigs one at a time, nose to tail. The chute does the job of sorting and sequencing the pigs so that the handler does not have to physically separate them. The width of the chute is the most important dimension. For market pigs weighing 250 to 300 pounds, the chute should be 16 to 24 inches wide. For finishing pigs in the 150 to 250 pound range, 16 to 18 inches is adequate. For weaned pigs and growers, 12 to 16 inches works well. The goal is to allow the pig to walk forward comfortably without being able to turn around. If the chute is too wide, pigs will turn around and face the handler. If it is too narrow, pigs will balk at the tight squeeze and may injure themselves trying to push through. The height of the chute walls should be at least 40 to 48 inches for market hogs. Pigs can jump surprisingly high when frightened, and a low wall invites them to try. Solid walls are essential. Pigs will not move forward if they can see other pigs, people, or movement through the sides of the chute. Solid walls also reduce noise and visual distractions that cause balking. The length of the chute should be as short as possible while still serving its purpose. A chute that is too long gives pigs more time to stop and balk. A chute that is too short does not give the handler enough control over the flow of pigs. In general, a chute of 10 to 20 feet is adequate for most loading situations. If you need a longer chute, consider adding a gate in the middle so you can break the chute into sections. The chute should have no sharp turns. Each turn is a point where pigs can balk and where the handler loses visual contact. If you must have a turn, make it a long gradual curve rather than a 90 degree corner. A radius of 8 to 10 feet for the curve is ideal. The curve should be banked slightly, with the inside of the curve lower than the outside, so that pigs naturally lean into the turn. The floor of the chute needs to provide secure footing. A rough broom finish on concrete is standard. Some facilities use a rubber mat or a textured epoxy coating to improve traction and reduce noise. The floor should be sloped slightly toward the loading ramp, about 1 to 2 percent, to encourage forward movement. Avoid any changes in floor level within the chute. A step or a lip is a major obstacle for a pig. The chute should have a non-slip surface even when wet. This is critical for the loading ramp, but it also matters in the chute because pigs urinate and defecate when stressed. A wet concrete floor can be dangerously slippery. If you are building new, specify a broom finish or an exposed aggregate finish that provides traction in all conditions. Solid sides on the chute also help with worker safety. A handler can walk alongside the chute and operate gates without being in direct contact with the pigs. The chute should have a walkway or working space on at least one side, wide enough for a person to move comfortably. This walkway should be separated from the chute by the solid wall, with gates that can be operated from the walkway side. ## The Turnaround and Sorting Area If your handling facility serves multiple purposes, such as sorting pigs by weight, treating sick animals, or moving pigs between barns, you need a turnaround or sorting area. This is a wider section of the chute where a pig can turn around or where you can divert pigs into different directions. The simplest turnaround is a circular or square pen that connects to the chute at two points. The pig enters from one side, the handler closes a gate behind it, and then opens the gate on the other side to let the pig continue. This works well for sorting, but it slows down the flow of pigs significantly. Only use a turnaround if you truly need to change the direction of travel. A better approach for many farms is to use a sorting gate within the chute itself. This is a gate that can be set to direct pigs either straight ahead or to one side. The handler sets the gate before the pig arrives, so the pig never has to make a decision. This works well for separating market hogs from cull sows or for directing pigs to different truck compartments. If you are designing a facility that handles both loading and processing, such as weighing or vaccinating, plan the layout so that these tasks happen in a separate area that does not interfere with the loading flow. A processing chute can be a side branch off the main chute, with a gate that directs pigs either to the processing area or to the loading ramp. The turnaround and sorting area should follow the same design principles as the rest of the facility. Solid walls, even lighting, non-slip floors, and no sharp corners. The area should be large enough for a handler to work comfortably but small enough that pigs cannot turn around and escape back into the chute. ## The Loading Ramp The loading ramp is the bridge between your farm and the truck. It is the most physically demanding part of the handling system for both pigs and workers, and it is where most injuries occur. A well-designed ramp is safe, comfortable for the pigs, and easy for the handler to manage. The angle of the ramp is the single most important factor. The recommended maximum slope is 20 degrees, and many experts recommend 15 degrees or less for market hogs. At 20 degrees, a 280 pound pig must lift its front feet 20 inches for every 5 feet of ramp length. That is a significant physical effort, especially for pigs that are already stressed from moving through the facility. At 25 degrees, many pigs will simply refuse to climb. The length of the ramp is determined by the angle and the height of the truck bed. A typical livestock trailer has a bed height of 30 to 48 inches. To achieve a 20 degree angle with a 48 inch bed height, you need a ramp that is about 12 feet long. For a 15 degree angle, you need about 16 feet. If you are building a fixed ramp, measure the height of the trucks you use most often and design accordingly. If you use multiple truck types with different bed heights, consider an adjustable ramp or a hydraulic lift. The ramp should be 24 to 30 inches wide for market hogs. This is wider than the single-file chute because the pig needs a little more room to balance on the incline. The sides of the ramp should be solid, extending at least 48 inches above the floor. The pig should not be able to see over the sides, especially at the top of the ramp where the truck bed creates a gap. The transition from the chute to the ramp is a critical point. There should be no gap between the end of the chute and the start of the ramp. Any gap or change in level will cause pigs to balk. The transition should be a smooth, continuous surface with no lip or step. If the ramp is adjustable, ensure that it locks securely in place so that it does not move or bounce when the pig steps onto it. The transition from the ramp to the truck is equally important. The ramp should overlap the truck bed by at least 6 to 12 inches so that there is no gap between the ramp and the truck floor. The ramp should be level with the truck bed or slightly above it, never below it. A pig that has to step up into the truck will hesitate, while a pig that steps down will move more readily. The floor of the ramp needs maximum traction. Use a rough broom finish, an exposed aggregate finish, or a commercial non-slip coating. Some facilities install cleats or crossbars on the ramp floor, but these can trip pigs if they are too high. A better approach is to use a surface that provides traction without creating a step. The ramp should also have a slight crown in the center, about 1 inch higher in the middle than at the edges, so that water drains off and does not pool. Every loading ramp should have a roof or cover. A roof protects the pigs from sun, rain, and snow, all of which cause balking. It also protects workers and keeps the ramp surface dry. If a full roof is not practical, at least build a cover over the top half of the ramp where the pigs are most likely to hesitate. ## Adjustable Ramps and Hydraulic Lifts Fixed ramps are the simplest and cheapest option, but they only work well if your trucks all have the same bed height. Many farms use multiple truck types, including semi-trailers, straight trucks, and gooseneck trailers, each with a different bed height. In these situations, an adjustable ramp is worth the extra cost. The simplest adjustable ramp is a hinged ramp that can be raised or lowered with a winch or a hydraulic cylinder. The ramp pivots at the base and the free end rests on the truck bed. The handler adjusts the height for each truck, and the ramp locks in place. This system requires a solid base at the pivot point and a sturdy frame that can handle the weight of multiple pigs. A more sophisticated option is a hydraulic lift table. The pig walks onto a platform at ground level, the platform rises to the height of the truck bed, and the pig walks out onto the truck. This eliminates the ramp angle entirely, which is the most pig-friendly option. Hydraulic lifts are more expensive and require regular maintenance, but they are the best choice for operations that load large numbers of pigs on a regular basis. If you are considering an adjustable ramp, think about the range of heights you need to accommodate. A typical range is 24 to 60 inches above ground level. The ramp needs to be long enough to reach the truck at the lowest angle possible, which means it needs to be longer than a fixed ramp. A 16 to 20 foot adjustable ramp can handle most truck heights at an acceptable angle. The adjustable ramp should have a mechanism to prevent the free end from slipping off the truck bed. A lip or a hook that engages with the truck bed is essential. The ramp should also have a safety chain or strap that secures it to the truck so it cannot fall if the truck moves. ## Gates, Latches, and Handles The gates in your handling facility are the primary tools your workers use to control pig movement. Poorly designed gates cause frustration, delays, and safety hazards. Well-designed gates make the facility feel almost automatic. Every gate in the facility should swing in the direction of pig flow. A gate that opens toward the pig is a barrier that the pig will try to avoid. A gate that opens away from the pig, or that slides sideways, is less intimidating. The gate should be solid, not barred, so that the pig cannot see through it to the other side. Gate latches should be easy to operate with one hand while holding a sorting board or a pig handler in the other. A simple latch that lifts and swings is better than a complex mechanism that requires two hands. The latch should be located on the handler's side of the gate, never on the pig side. It should also be located high enough that a pig cannot reach it with its snout. Handles and latches should be made of materials that do not conduct extreme temperatures. Metal handles can become freezing cold in winter and burning hot in summer. A rubber or plastic coating on the handles makes them more comfortable and safer to use. The handles should also be positioned so that the handler does not have to reach over the gate or into the pig area to operate them. Consider the height of the gate. A gate that is too low allows pigs to jump over it. A gate that is too high is awkward to operate and creates a visual barrier that may be intimidating. For market hogs, a gate height of 40 to 48 inches is standard. The gate should be mounted on sturdy hinges that can withstand the weight of pigs pushing against them. Slide gates are often better than swing gates in narrow chutes. A slide gate moves horizontally across the chute and does not take up space in the handler's walkway. Slide gates are also less likely to catch a pig's leg or head because they do not swing through the pig space. The slide mechanism should be mounted in a track that is protected from manure and debris, and it should be lubricated regularly. ## Lighting and Visual Design Lighting is one of the most overlooked aspects of pig handling facility design. Pigs are highly sensitive to light contrast and will balk at shadows, bright spots, and sudden changes in illumination. The goal is to create an environment that is evenly lit, with the brightest area at the destination. The general principle is to keep the lighting level consistent throughout the handling facility. The crowd pen should be lit at the same level as the chute, and the chute should be lit at the same level as the ramp. The truck interior should be the brightest area, drawing the pigs forward. If the truck is dark, the pigs will stop at the ramp and refuse to enter. For indoor facilities, use multiple light sources rather than a single bright light. A single light creates harsh shadows and a strong contrast between the lit area and the surrounding darkness. Multiple lights, spaced evenly, create a more uniform illumination. Use diffusers or frosted covers on the lights to soften the beam and reduce glare. The color of the lighting matters less than the uniformity. Pigs are dichromats, so they do not see the full color spectrum that humans do. However, they are sensitive to the intensity of light. A facility that is too dark will make pigs nervous, while a facility that is too bright can cause glare and discomfort. Aim for a moderate light level, about 50 to 100 lux, in the handling areas. Avoid placing lights where they shine directly into the pigs' eyes. A light at the chute entrance should be positioned above and behind the pig, not directly in its line of sight. The light should illuminate the path ahead without creating a bright spot that the pig has to look into. If your facility is outdoors, consider the position of the sun throughout the day. The ideal orientation has the sun behind the pigs as they move through the facility. If the sun is in the pigs' eyes, they will stop and refuse to move. A roof or shade structure over the handling area can eliminate this problem. ## Floors and Non-Slip Surfaces The floor is the surface that the pig feels with every step. A floor that is slippery, uneven, or uncomfortable will make pigs reluctant to move. A floor that provides secure footing and a consistent surface will keep pigs moving confidently. The standard floor for pig handling facilities is concrete with a rough broom finish. This provides good traction for both pigs and workers, and it is easy to clean and disinfect. The concrete should be cured properly before use, and it should be sealed to prevent moisture from penetrating and creating a slippery film. For areas that get particularly wet, such as the loading ramp and the area around the truck, consider a more aggressive surface. Exposed aggregate concrete, where the smooth top layer is washed away to reveal the rough stones beneath, provides excellent traction. Another option is a commercial non-slip coating that can be applied over existing concrete. These coatings are available in a range of colors and textures, and they can be reapplied as they wear. Rubber matting is another option, particularly for the chute and the crowd pen. Rubber provides excellent traction, reduces noise, and is more comfortable for the pigs to walk on than concrete. The downside is that rubber mats are more expensive and can be damaged by sharp hooves or by the equipment used to clean the facility. If you use rubber matting, make sure it is properly secured to the floor so that it does not shift or buckle. The floor should be sloped for drainage, but the slope should not be so steep that it interferes with pig movement. A slope of 1 to 2 percent is ideal for the crowd pen and chute. The loading ramp will have a steeper slope by necessity, but the surface must provide adequate traction at that angle. Never use steel or metal grates for the floor of a pig handling facility. The metal is slippery when wet, it is noisy, and pigs can catch their hooves in the gaps. Similarly, avoid wooden floors. Wood becomes slippery when wet, it absorbs urine and manure, and it is difficult to clean and disinfect properly. ## Worker Safety and Ergonomics The people who work in your handling facility are your most valuable resource. A facility that is dangerous or uncomfortable for workers will have high turnover and low productivity. A facility that is designed with worker safety in mind will attract and retain good employees. The handler should never have to enter the crowd pen or the chute with the pigs. Every operation should be possible from outside the pig area, using gates, panels, and sorting boards. This protects the worker from injury and reduces stress on the pigs. If a worker must enter the pen, it should be a last resort, and the worker should have an escape route. The walkways alongside the chute should be at least 24 to 30 inches wide. This gives the worker enough room to move comfortably and to operate gates without being crowded. The walkway should have a non-slip surface and should be kept clear of debris and equipment. The handler's working height should be considered. A chute that is too high forces the worker to reach over the wall to operate gates. A chute that is too low forces the worker to bend over. The ideal height for the top of the chute wall is about 36 to 40 inches, which is comfortable for most adults. If you have workers of significantly different heights, consider adjustable gates or platforms. Provide the workers with the right tools. A sorting board is a solid panel, about 24 by 36 inches, that the handler uses to guide pigs without touching them. A pig handler, also called a pig board or a hog paddle, is a smaller version that can be used in tighter spaces. These tools are more effective and safer than using hands, feet, or electric prods. Electric prods should be a last resort, not a primary tool. The use of electric prods causes stress, increases the risk of injury, and makes pigs more difficult to handle in the future. Many large packing plants now refuse to accept pigs that arrive with electric prod marks. If you must use a prod, use it sparingly and only on the rear of a pig that is refusing to move, never on the head, face, or genitals. ## Biosecurity and Cleaning The handling facility is a high-traffic area where pigs from different barns and different farms can come into contact with each other. It is also the area where outside vehicles and people, such as truck drivers, come closest to your herd. Biosecurity is therefore a critical part of the design and operation of your facility. The loading ramp should be the boundary between the clean area of your farm and the dirty area. The truck and the driver should never cross this boundary. The ramp should be designed so that the driver can operate the truck gate from the cab or from a designated walkway on the dirty side. If the driver needs to enter the trailer, they should use a separate entrance, not the ramp that the pigs use. The handling facility should be easy to clean and disinfect. Use smooth, non-porous materials that do not absorb manure or urine. Concrete is ideal, but it should be sealed to prevent moisture from penetrating. Avoid wood, which is porous and difficult to clean. Avoid materials with crevices or seams where organic matter can accumulate. Design the facility with a cleaning plan in mind. The floors should slope to drains that carry wash water and manure to a proper storage facility. The walls should be smooth and easy to hose down. The lighting fixtures should be sealed or positioned so that they do not get wet during cleaning. The gates and latches should be made of materials that can withstand regular washing and disinfection. Have a written cleaning and disinfection protocol for the handling facility. After each loading event, remove all manure and organic matter, wash the surfaces with detergent, rinse, and apply a disinfectant that is approved for livestock facilities. Allow the surfaces to dry completely before the next use. Keep a log of when the facility was cleaned and what products were used. The crowd pen and chute should also be cleaned between groups of pigs from different barns. If you are loading pigs from multiple barns in one day, clean the facility between loads to prevent the spread of disease. This is especially important if you are moving pigs to a processing plant, because the facility can become contaminated with pathogens from the truck. ## Common Mistakes in Handling Facility Design Many farms have handling facilities that do not work well, and the problems are usually the result of a few common design mistakes. Understanding these mistakes can help you avoid them in a new build and can help you diagnose problems in an existing facility. The most common mistake is making the chute or crowd pen too large. A chute that is too wide allows pigs to turn around. A crowd pen that is too large allows pigs to bunch up and form groups that are difficult to move. The temptation is to build everything bigger than necessary to accommodate the largest pigs, but this creates problems with the average-sized pigs that you handle most often. Another common mistake is using barred or open-sided chutes. Pigs are curious and easily distracted, and they will stop to look at anything they can see through the bars. They will also balk if they can see other pigs or people moving around outside the chute. Solid sides eliminate these distractions and make the pigs focus on the path ahead. Sharp turns are a frequent problem. A 90 degree turn in the chute is a natural point for pigs to balk, especially if the turn is tight. Pigs cannot see around the corner, and they are reluctant to move into an area they cannot see. If you must have a turn, make it a long, gradual curve with a radius of at least 8 to 10 feet. Poor lighting is another common issue. A facility that is dimly lit or that has harsh shadows will make pigs nervous and reluctant to move. The lighting should be even and consistent throughout the facility, with the brightest area at the destination. If the truck interior is dark, the pigs will stop at the ramp. The floor is often overlooked. A smooth concrete floor that is fine for the barn may be dangerously slippery in the handling facility, especially when wet. The floor needs a rough finish that provides traction in all conditions. The loading ramp especially needs a high-traction surface. Inadequate drainage is a frequent problem. Water and manure accumulate in the crowd pen and chute, creating a slippery, smelly environment that pigs avoid. The facility should be sloped to drains, and the drains should be sized to handle the volume of water used during cleaning. Finally, many farms fail to plan for the truck interface. The ramp may not match the height of the truck, or there may be a gap between the ramp and the truck bed. These problems cause pigs to balk at the critical moment when they are about to enter the truck. The transition from the ramp to the truck must be smooth, level, and free of gaps. ## Monitoring, Recordkeeping, and Performance Metrics Once your handling facility is built, you need to measure how well it is working. The only way to know if your investment is paying off is to track key performance metrics over time. This data also helps you identify problems before they become serious. The most important metric is loading time. How long does it take to load a full truck of pigs? This includes the time from when the first pig leaves its pen to when the last pig is secured in the truck. A well-designed facility should allow you to load a full truck in 30 to 60 minutes, depending on the number of pigs. If your loading time is much longer, there is a problem in the facility or in the handling technique. Shrink is another critical metric. Shrink is the weight loss that pigs experience during loading and transport. Some shrink is unavoidable, but excessive shrink is a sign of stress and poor handling. Weigh a sample of pigs before loading and then weigh them again at the packing plant or at the destination. A shrink of 1 to 2 percent is normal for a short trip. Anything more than 3 percent indicates that the pigs are being stressed excessively. Bruising is a direct indicator of facility problems. If pigs are arriving at the packing plant with bruises, it means they are being injured during loading or transport. Track the number and severity of bruises, and note where they occur on the body. Bruises on the shoulders and hips often indicate that the chute or ramp is too narrow. Bruises on the back often indicate that the pigs are being climbed on by other pigs in the crowd pen. Worker injuries are also a key metric. If your workers are getting hurt, the facility is not safe. Track all injuries, no matter how minor. Look for patterns in the types of injuries and where they occur. A facility that causes frequent injuries will have high worker turnover and low morale. Keep a log for each loading event. Record the date, the number of pigs loaded, the time it took, the weather conditions, the truck type, and any problems that occurred. This log will help you identify patterns over time. For example, you might notice that loading takes longer on rainy days, which could indicate a drainage problem. Or you might notice that a particular truck type always causes problems, which could indicate a ramp height issue. Review your records quarterly and make adjustments as needed. If loading time is increasing, look for wear and tear on the facility. Gates that are difficult to operate, floors that have become smooth, and lighting that has dimmed can all contribute to slower loading. Regular maintenance of the facility is just as important as the initial design. ## When to Call a Professional Most handling facility problems can be solved with good design and good management. However, there are times when you should call in a professional for help. Knowing when to ask for assistance can save you time and money in the long run. If you are planning a new facility from scratch, consider consulting with a livestock facility designer or an agricultural engineer. These professionals have experience with pig behavior and can help you avoid the common mistakes that plague DIY facilities. The cost of a consultation is small compared to the cost of building a facility that does not work. If you are renovating an existing facility and the problems persist despite your best efforts, a professional assessment can help. An expert can walk through your facility, observe the pigs' behavior, and identify the specific design flaws that are causing problems. They can also provide recommendations for fixes that are more cost-effective than a full rebuild. If you are experiencing a sudden increase in injuries, either to pigs or to workers, call a professional immediately. This could indicate a structural issue, such as a failing gate or a deteriorating floor, that is a safety hazard. Do not wait for an accident to happen before you address the problem. Your local extension agent can also be a valuable resource. Cooperative Extension offices in pig-producing states have specialists who can provide advice on facility design, pig behavior, and handling techniques. They can also connect you with other farmers who have built successful handling facilities and who can share their experiences. If you notice signs of illness or distress in your pigs during handling, such as excessive panting, trembling, or reluctance to move, contact your veterinarian. These symptoms can indicate a health problem that is unrelated to the facility design. Your veterinarian can help you determine whether the issue is physical, behavioral, or environmental. ## Frequently Asked Questions **How wide should a pig chute be for market hogs?** For market hogs weighing 250 to 300 pounds, the chute should be 16 to 24 inches wide. The goal is to allow the pig to walk forward comfortably without being able to turn around. If the chute is too wide, the pig will turn around and face the handler. If it is too narrow, the pig will balk at the tight squeeze. For smaller pigs, reduce the width accordingly. Weaned pigs need 12 to 16 inches, and growers in the 150 to 250 pound range need 16 to 18 inches. **What is the best angle for a pig loading ramp?** The recommended maximum angle for a pig loading ramp is 20 degrees, and many experts recommend 15 degrees or less for market hogs. The angle is determined by the height of the truck bed and the length of the ramp. To achieve a 20 degree angle with a 48 inch truck bed, you need a ramp about 12 feet long. For a 15 degree angle, you need about 16 feet. A steeper ramp causes pigs to balk, increases the risk of injury, and causes excessive shrink. **Why do my pigs refuse to enter the chute?** Pigs refuse to enter the chute for several common reasons. The most common is that they can see something that frightens them, such as a person, a shadow, or a change in light intensity. Pigs also refuse to enter if the chute is too narrow, if the floor is slippery, or if they have had a bad experience in the chute before. Check the lighting, the floor surface, and the width of the chute. Make sure the sides are solid so the pig cannot see distractions. If the pig has had a bad experience, you may need to retrain it with positive reinforcement. **How many pigs should I put in the crowd pen at once?** The crowd pen should hold no more than 5 to 8 market hogs at a time. This is enough to maintain the following instinct that encourages forward movement, but not so many that the pigs bunch up and fight. The crowd pen should be round or rounded, with a radius of 6 to 10 feet for market hogs. Overcrowding the crowd pen causes stress and makes movement more difficult. **Do I need a hydraulic lift for my loading ramp?** A hydraulic lift is not necessary for every farm. If you use a single truck type with a consistent bed height, a fixed ramp is sufficient. If you use multiple truck types with different bed heights, an adjustable ramp or a hydraulic lift will save you time and reduce stress on the pigs. A hydraulic lift eliminates the ramp angle entirely, which is the most pig-friendly option, but it is also the most expensive. Consider your trucking situation and your budget before making a decision. **How do I clean and disinfect my handling facility?** After each loading event, remove all manure and organic matter from the facility. Wash the surfaces with a detergent designed for livestock facilities, then rinse thoroughly. Apply a disinfectant that is approved for use in livestock facilities, following the label instructions for dilution and contact time. Allow the surfaces to dry completely before the next use. Pay special attention to the loading ramp, which is the area most likely to be contaminated by the truck. Keep a log of your cleaning activities and the products you use. **What should I do if a pig gets injured in the chute?** If a pig gets injured in the chute, stop the loading process immediately and assess the situation. If the injury is minor, such as a small cut or a bruise, you may be able to continue after treating the wound. If the injury is serious, such as a broken leg or a deep laceration, remove the pig from the chute and contact your veterinarian. Do not attempt to treat a serious injury yourself. After the incident, inspect the chute to identify what caused the injury and make repairs before resuming loading. **How can I reduce shrink during loading?** Shrink is caused by stress, and stress is caused by poor handling and poor facility design. To reduce shrink, make sure your facility is designed to minimize stress. The chute should be the right width, the ramp should be at a low angle, the lighting should be even, and the floors should have good traction. Handle the pigs calmly and quietly, using sorting boards and gates rather than electric prods. Load the pigs as quickly as possible, but do not rush them. A well-designed facility and a calm handler can reduce shrink by 1 percent or more. ## Related Farming Guides This section will be populated with links to related farming guides on pig housing, swine health, livestock transport, and farm biosecurity.
