Farrowing and Nursery Barn Maintenance Schedules

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

Key Takeaways

• Daily checks are critical for vulnerable pigs: Inspect water flow (sow: ~2 qt/min, nursery: ~1 qt/min), heat sources (90-95°F floor for newborns, 85-90°F for weaned pigs), and ventilation fan operation to prevent rapid dehydration, chilling, or respiratory/scour disease outbreaks.
• Weekly system inspections prevent gradual failures: Clean fan blades and shutters to maintain airflow, check belt tension and motor heat to ensure efficient ventilation, and flush water lines to remove biofilm that harbors bacteria and obstructs drinkers.
• Seasonal preparation mitigates environmental stress: Pre-summer checks of cooling systems (evaporative pads, fans) and pre-winter checks of heating equipment (gas heaters, insulation) and backup power are essential to maintain optimal thermal comfort for pigs.
• All-in, all-out cleaning protocols are paramount for biosecurity: Thoroughly dry scrape, soak with detergent, high-pressure wash, rinse, disinfect, and dry all surfaces to break disease cycles between groups, as organic matter inactivates disinfectants.
• Proactive repair and replacement prevent costly failures: Replace worn crate flooring, feeder edges, and drinker mounts before they cause injury or restrict intake, and consider replacing fans older than 10-15 years or controllers over 10 years old for improved efficiency and monitoring.
• Comprehensive recordkeeping identifies trends and informs decisions: Document all maintenance, repairs, cleaning cycles, and environmental deviations to track equipment performance, plan capital expenditures, and collaborate with veterinarians on disease investigations.

Keeping a farrowing and nursery barn operating well depends on more than good pigs and sound nutrition. The building, the equipment, and the daily systems inside it need regular attention. A written maintenance schedule protects your animals, your staff, and your investment in the facility itself. This guide covers the full scope of farrowing and nursery barn upkeep: daily checks, weekly tasks, seasonal deep cleaning, equipment repair thresholds, biosecurity routines, and recordkeeping. It is written for farm owners, herd managers, and crew leads who plan and carry out maintenance in swine operations.

At a Glance

• Clean and disinfect farrowing rooms between groups using an all-in, all-out approach.
• Check water flow and drinker function daily in every pen.
• Inspect heat lamps, mats, and controllers each day during farrowing and the first weeks of nursery life.
• Test ventilation controllers and emergency inlets weekly during hot and cold extremes.
• Replace worn crate flooring, feeder edges, and drinker mounts before they injure pigs.
• Keep a written log for every repair, part replacement, and cleaning cycle.
• Schedule a full barn inspection at least twice per year, ideally before hot and cold seasons.
• Call your veterinarian when pig losses, injury rates, or disease signs do not respond to routine correction.

Why Maintenance Matters in Farrowing and Nursery Barns

Farrowing and nursery barns hold the most vulnerable pigs on the farm. Newborn piglets have limited body fat, immature immune systems, and a narrow range of thermal comfort. Nursery pigs are adjusting to solid feed, new pen mates, and a changing environment. Small failures in equipment or building function become large problems quickly in these rooms.

A clogged drinker can dehydrate a sow in a few hours. A failed heat lamp leaves a litter chilled within minutes. A ventilation controller that drifts out of calibration can create drafts, stale air, or temperature swings that trigger scours or respiratory disease. These are not rare events. They are the predictable results of deferred maintenance.

A maintenance schedule protects against these failures by making checks routine rather than reactive. It also extends the life of expensive equipment. A crate floor that is repaired when a weld breaks lasts years longer than one that is left to fail completely. A fan belt replaced in the spring does not strand you in August. The goal is to find small problems while they are cheap and easy to fix.

This article is for anyone who plans or performs maintenance in farrowing and nursery barns. It gives you a practical schedule, clear procedures, and decision points for when to repair, replace, or call for help.

Daily Maintenance Checks

Daily checks are the backbone of the maintenance schedule. They take minutes per room but catch most problems before they become emergencies. Assign these checks to the same person each day so they learn what normal looks like in each room.

Water Systems

Check every drinker in the farrowing and nursery rooms daily. Push the nipple or bite valve and confirm water flows freely. Look at the flow rate. A sow drinker should deliver about 2 quarts per minute. A nursery drinker should deliver about 1 quart per minute. If the flow looks weak, check the supply line, the filter, and the drinker itself.

Watch for leaks around drinker mounts and pipe joints. A slow drip can keep bedding wet and raise humidity. A larger leak can waste hundreds of gallons and undermine the floor. Dry the area around each drinker mount and check again the next day to see if the leak returned.

Check water medication equipment if you use it. Confirm the stock solution is being drawn down at the expected rate. Look for air locks in the lines and make sure the injection port is clean.

Feed Systems

Walk the feed lines in nursery rooms each day. Look for bridged feed in bins and hoppers. Tap on bins and check that feed is moving. Clear any blockages before pigs run empty.

Check feeder adjustment. In nursery pens, feeders should allow feed to flow but not pile up wastefully. Look at the pan. If feed is stale or wet, adjust the flow and clean the pan. In farrowing rooms, check the sow feeder for leftover feed that has soured or molded. Remove and discard uneaten feed daily.

Inspect auger systems for unusual noise or vibration. A rhythmic knocking can signal a worn bearing or a bent section of auger. Note the sound and check the drive unit.

Heating and Cooling

Check heat lamps and heat mats in every farrowing crate and nursery pen. Look for bulbs that have burned out and fixtures that have come loose. Position heat lamps at the correct height above the pigs. A lamp that is too low can burn piglets. A lamp that is too high does not provide enough warmth.

Check the temperature under the heat source. Use a hand held infrared thermometer or a probe thermometer placed at piglet level. Newborn piglets need a floor temperature near 90 to 95 degrees Fahrenheit for the first few days. Nursery pigs need a floor temperature near 85 to 90 degrees at weaning, decreasing gradually.

Inspect heat mats for cracks, exposed wires, and loose connections. A damaged mat is an electrical hazard and a burn risk. Replace any mat with visible damage immediately.

Ventilation

Do a quick visual check of the ventilation system each day. Look at the exhaust fans. Confirm they are turning and moving air. Listen for unusual noises from fan motors and shutters. Look at the air inlets. They should be open to match the fan stage that is running.

Check the temperature in each room against the controller set point. A room that is running warmer or cooler than the set point may have a controller problem or a ventilation component failure. Investigate before the condition worsens.

Watch the pigs. Pigs that are huddled and shivering tell you the room is too cold. Pigs that are spread out, panting, and avoiding the heat source tell you the room is too warm. Pigs are the best sensor you have. Learn to read them.

Piglet and Sow Health Checks

Daily maintenance includes checking the animals that use the equipment. Look for signs that equipment is causing injury. Check piglets for scrapes, cuts, and swollen joints. A piglet with a raw hock or knee may be catching a foot in the crate floor or rubbing against a sharp edge.

Check sows for injuries to the udder, teats, and feet. A sow that is stepping awkwardly may have a foot injury from a damaged floor or a crate divider. Look for swellings, redness, and open sores.

Check that crates and pens have no sharp edges, protruding bolts, or broken welds at pig level. Run your hand along edges that pigs contact. Repair or cover any sharp spots.

Manure and Drainage

Check manure removal systems daily. In rooms with flush systems, confirm that flush tanks fill and empty on schedule. Look for plugged flush ports and manure buildup in gutters. In rooms with scrapers, check that the scraper travels the full length of the gutter and returns properly.

Check drains and sumps. Remove any debris that could plug a drain. Look for standing water where it should not be. Standing water in a nursery room raises humidity and increases the risk of disease spread.

Weekly Maintenance Tasks

Weekly tasks take a little more time but catch problems that develop over several days. Schedule these for the same day each week so they become habit.

Ventilation System Inspection

Give the ventilation system a thorough check once per week. Clean fan blades and shutters. Dust and dirt buildup on blades reduces airflow and unbalances the fan. Use a brush and a shop vacuum. Check belts for tension and wear. A belt that is loose slips and reduces fan speed. A belt that is cracked or frayed should be replaced.

Check fan motors for heat and vibration. Feel the motor housing. If it is too hot to hold your hand on, the motor is working too hard. Look for signs of overheating such as discolored paint or a burnt smell.

Inspect the controller. Check the temperature sensor. Clean it if it is dusty. Verify that the controller is reading the actual room temperature by comparing it to a separate thermometer. If the sensor and the thermometer disagree by more than 2 degrees, calibrate or replace the sensor.

Test the alarm system. Most controllers have a high and low temperature alarm. Set the alarm to test and confirm it triggers. Check that the alarm is loud enough to hear in the areas where people work. If you have a phone dialer or remote alarm, test that too.

Check emergency inlets. They should open freely when the controller calls for them. Look for obstructions such as nests, dust, or debris. Confirm the inlet cables and pulleys move smoothly.

Heating System Checks

Inspect all heat lamps and fixtures weekly. Replace any bulb that is dimming or flickering. Check the condition of the lamp cords and plugs. A cord with cracked insulation or a loose plug is a fire hazard.

Clean heat lamp reflectors. A dirty reflector reduces the heat directed at the pigs and wastes electricity. Wipe reflectors with a dry cloth.

Check heat mat thermostats. Confirm the mat reaches the set temperature. Test each mat with a thermometer. Replace mats that do not heat evenly or that cycle on and off excessively.

Inspect gas heaters if you use them. Check for proper flame color. A blue flame is normal. A yellow flame indicates incomplete combustion. Check for gas leaks using a soap and water solution on the fittings. Look for signs of carbon monoxide buildup such as soot around the heater.

Water System Flushing

Flush all water lines once per week. Open the end of each line and let water run until it is clear. This removes sediment and biofilm that can plug drinkers and harbor bacteria.

Clean or replace inline water filters. A clogged filter reduces flow to every drinker downstream. Check the pressure gauge on the water system. Normal pressure for most swine barns is 40 to 60 psi. Low pressure can be a pump problem or a supply problem.

Check drinker height and position. Nursery drinkers should be at pig shoulder height. As pigs grow, adjust the drinker height. A drinker that is too low forces pigs to kneel. A drinker that is too high discourages drinking.

Pen and Crate Inspection

Walk every pen and crate once per week. Look at the flooring. Check for broken slats, loose boards, and protruding nails or screws. In farrowing crates, check the welds on the crate frame and the adjustability of the crate width.

Inspect feeder edges. Pigs rub against feeder edges constantly. A sharp edge can cause ear and shoulder lesions. Smooth any rough spots with a grinder or file.

Check gates and latches. A gate that does not latch securely can let pigs out. A latch that is hard to operate can injure a worker or stress a sow. Lubricate hinges and latches with a food grade lubricant.

Look at pen dividers. Check for gaps that allow piglets to move between litters. Piglet movement between litters spreads disease and causes fighting. Block any gaps you find.

Rodent and Pest Control

Check bait stations and traps weekly. Replace bait that is consumed or spoiled. Look for fresh droppings, gnaw marks, and tracks. An increase in rodent activity means your control program needs adjustment.

Check for birds in the barn. Birds carry disease and contaminate feed and water. Look for nests in rafters and around inlets. Seal any openings that allow birds to enter.

Inspect for flies. High fly populations indicate a sanitation problem. Look for breeding sites in spilled feed, wet bedding, and manure buildup. Clean up the source and use fly control measures as needed.

Monthly Maintenance Tasks

Monthly tasks focus on systems that wear gradually and need periodic attention. Put these on the calendar so they do not get skipped.

Electrical System Inspection

Check the main electrical panel and all subpanels monthly. Look for signs of overheating such as discolored breakers or a burnt smell. Tighten any loose connections. Check that all breakers are properly labeled.

Inspect all electrical cords and wiring in the animal areas. Look for cords that have been chewed by rodents, pinched by gates, or damaged by equipment. Replace any damaged cord immediately.

Check ground fault circuit interrupters. Press the test button on each GFCI outlet to confirm it trips. A GFCI that does not trip is not protecting you or your pigs. Replace it.

Test all emergency lighting. Clean the fixtures and replace dead batteries. Confirm that exit signs are visible and lit.

Floor and Surface Repair

Inspect concrete floors for spalling, cracks, and erosion. Concrete that is breaking down creates rough surfaces that injure feet and are hard to clean. Patch small areas with a concrete repair product rated for animal areas.

Check epoxy or sealant coatings on floors and walls. Look for peeling, cracking, and worn areas. Repair damaged coatings before they allow moisture into the concrete.

Inspect wall surfaces. Look for holes, cracks, and damaged panels. Repair any damage that could harbor bacteria or injure pigs. Pay special attention to corners and edges where cleaning equipment may have damaged the surface.

Plumbing and Drainage

Check all plumbing fixtures and pipes monthly. Look for leaks at joints and fittings. Check pipe hangers and supports. A sagging pipe can collect water and eventually fail.

Inspect the manure handling system. Check flush tanks for proper fill and dump cycles. Look at the flush ports and gutter floors for wear. Check the operation of pit fans if you have a deep pit system.

Clean drain lines and traps. Use a drain cleaner or a plumber snake to clear any buildup. Check that all floor drains have working strainers and that the strainers are in place.

Feed System Maintenance

Lubricate feed auger bearings and drive units monthly. Check the gearbox oil level. Look for wear on auger flighting, especially at corners and transitions.

Inspect feed bins. Look for rust, holes, and damaged lids. Check the bin vents to make sure they are not plugged. A plugged vent can cause feed to bridge in the bin.

Check the condition of feed drop tubes and flexible connections. Look for wear and leaks. A leak in a feed line wastes feed and attracts pests.

Seasonal Maintenance Tasks

Seasonal tasks prepare the barn for the coming weather. The two critical seasons are hot weather and cold weather. Plan these checks before the season arrives, not after the weather changes.

Pre-Summer Maintenance

Before hot weather arrives, test the entire cooling system. Clean all evaporative cooling pads. Replace pads that are worn, plugged, or falling apart. Check the water distribution system for the pads. Confirm that water flows evenly across the top of each pad.

Check all fans, especially the large exhaust fans used in hot weather. Clean blades and shutters. Check belts and motors. Test each fan individually to confirm it runs at full speed.

Inspect the cooling system controller. Verify that the temperature settings match your barn design. Check that the cooling stages activate in the correct order. Test the high temperature alarm.

Check the water supply for the cooling system. Confirm that the well or municipal supply can deliver enough water. Check the pressure and flow rate. If the water supply is marginal, the cooling system will not perform.

Check attic and ceiling insulation. Poor insulation allows heat to radiate into the rooms. Look for areas where insulation has settled, been damaged, or is missing.

Pre-Winter Maintenance

Before cold weather arrives, check all heating equipment. Clean and service gas heaters. Check the heat exchangers, burners, and controls. Test the ignition system. Confirm that the heater cycles on and off properly.

Check the ventilation system for winter operation. Confirm that minimum ventilation fans are working. Clean the minimum ventilation inlets. Check that the controller is set for winter minimum ventilation rates.

Check the barn for drafts. Walk the inside of the barn and look for light coming through cracks and gaps. Seal any openings around doors, windows, and wall penetrations. A draft at pig level can chill a litter and trigger scours.

Inspect the building envelope. Check the roof for leaks. Look at the condition of the siding and the foundation. Repair any damage before winter weather makes it worse.

Check the backup power system. If you have a generator, run it under load. Change the oil and filter. Check the fuel supply. Test the automatic transfer switch. Confirm that the generator starts and powers the critical systems.

Check the alarm system. Test the temperature alarms and the power failure alarm. Confirm that the alarm is working and that the phone numbers or contacts in the system are current.

Spring and Fall Deep Cleaning

Spring and fall are good times for a more thorough cleaning of the entire barn. This goes beyond the between-group cleaning and addresses the building itself.

Wash walls, ceilings, and partitions. Use a high pressure washer and a detergent rated for livestock facilities. Pay attention to corners, ledges, and other areas where dust and organic matter accumulate.

Clean fan housings and shutters thoroughly. Remove the fan blades and wash them. Clean the fan shrouds and the surrounding wall area. Check the condition of the fan bearings and motors while they are accessible.

Clean light fixtures and replace bulbs that are dim or burned out. Check the condition of the fixtures themselves. Replace any fixture with cracks or corrosion.

Inspect the entire building structure. Look at the roof trusses, purlins, and support posts. Check for signs of rot, corrosion, or insect damage. Look at the condition of the siding and the foundation. Note any areas that need repair.

All-In, All-Out Cleaning and Disinfection

The most important cleaning event in a farrowing or nursery barn is the between-group clean. This is the time to break the disease cycle and give the next group of pigs a clean start. The process is the same for farrowing rooms and nursery rooms.

Step 1: Remove All Animals and Equipment

Move the last group of pigs out of the room. Remove all portable equipment from the room. This includes feeders, heat lamps, mats, creep dividers, and any other movable items. Take the equipment to a wash area where it can be cleaned separately.

Remove all feed from feeders and bins. Remove all bedding material. Remove any dead pigs and any leftover medication or supplies.

Step 2: Dry Clean

Remove all visible organic matter before washing. Use a scraper or shovel to remove manure and soiled bedding. Sweep the floor and the walls. The goal is to remove as much organic matter as possible before any water is applied.

Organic matter inactivates disinfectants. If you wash before you scrape, you simply spread the organic matter around. Dry cleaning is the most important step in the entire process.

Step 3: Soak

Apply a detergent solution to all surfaces. Use a foaming detergent that clings to vertical surfaces. Cover the floor, walls, crates, and any fixed equipment. Let the detergent soak for the time recommended on the label. This softens organic matter and makes it easier to remove.

Step 4: Wash and Rinse

Use a high pressure washer to remove all organic matter. Work from the top of the room down. Wash the ceiling, then the walls, then the floor. Pay special attention to cracks, corners, and equipment mounts where organic matter collects.

Rinse all surfaces with clean water. The rinse removes the detergent and any remaining organic matter. Check the rinse water as it runs off. If it is still dirty, wash and rinse again.

Step 5: Inspect

Inspect the room after washing. Look for areas that are still dirty. Check under feeders, behind crates, and in corners. Look at the condition of the surfaces. Note any damage that needs repair.

This is the time to make repairs. Fix broken welds, replace damaged flooring, and repair wall damage. Repairs made after cleaning and before disinfection will last longer and are easier to make.

Step 6: Disinfect

Apply a disinfectant approved for swine facilities. Follow the label directions for concentration, contact time, and temperature. Apply the disinfectant to all surfaces. Cover the floor, walls, and fixed equipment.

Let the disinfectant dry completely before bringing in new pigs. The drying time is part of the disinfection process. Do not rinse the disinfectant off unless the label says to rinse.

Step 7: Dry and Reassemble

Let the room dry completely. This is critical. A wet room is a cold room, and a cold room stresses pigs. Drying also helps break the disease cycle.

Reassemble the room. Install clean feeders, drinkers, heat lamps, and mats. Set up the crates or pens. Check that all equipment works before you bring in pigs.

Step 8: Document

Record the cleaning and disinfection on a log. Note the date, the product used, the concentration, and the person who did the work. This record is valuable for troubleshooting disease problems and for demonstrating your biosecurity practices.

Common Maintenance Mistakes

Farmers make several maintenance mistakes repeatedly. Knowing these helps you avoid them.

Waiting for Failure

The most common mistake is running equipment until it fails. A fan that is making noise is not a fan that needs watching. It is a fan that needs repair. A heat lamp that is flickering is not a lamp that is dying. It is a lamp that should be replaced.

Reactive maintenance is always more expensive than preventive maintenance. A fan belt that is replaced for a few dollars prevents a fan motor that costs hundreds. A drinker that is cleaned prevents a pig that is dehydrated.

Cleaning Without Scraping

Many people skip the dry cleaning step and go straight to washing. This mistake inactivates your disinfectant and leaves disease organisms behind. Organic matter is the enemy of disinfection. Scrape first, then wash.

Using the Wrong Disinfectant

Not all disinfectants work on all organisms. Some disinfectants are inactivated by organic matter. Some work better at certain temperatures. Some are corrosive to equipment.

Read the label. Choose a disinfectant that is effective against the diseases you are concerned about. Use it at the correct concentration and contact time. Rotate disinfectants to prevent the development of resistance.

Ignoring the Electrical System

Electrical problems are easy to ignore because they are invisible. A loose connection can cause a fan to run slowly or a heater to cycle improperly. A failing motor can draw excess current and create a fire hazard.

Check the electrical system on a schedule. Look for signs of overheating. Test GFCIs. Replace damaged cords. The electrical system is the nervous system of the barn.

Forgetting the Alarm System

The alarm system is your only protection when no one is in the barn. A dead battery or a disconnected phone line makes the alarm useless. Test the alarm regularly and confirm that it is working.

Not Training Staff

A maintenance schedule is only as good as the people who execute it. Train all staff on the daily and weekly checks. Show them what normal looks like. Teach them to report problems promptly.

One person cannot do all the maintenance on a large farm. Distribute the tasks and train backups. Cross train so that the farm runs when one person is on vacation or sick.

Decision Thresholds for Repair or Replacement

Every piece of equipment in the barn has a service life. Knowing when to repair and when to replace saves money and prevents failures.

Crate Flooring

Farrowing crate flooring takes heavy abuse from sows and piglets. Check the condition of the flooring at every cleaning. Look for broken slats, sharp edges, and worn areas.

Repair minor damage such as a single broken weld or a small chip. Replace flooring that has multiple breaks, significant wear, or rust that has weakened the structure. A rule of thumb is to replace flooring when more than 10 percent of the slats in a room are damaged.

Feeders

Feeders wear at the edges where pigs rub and at the adjustment mechanisms. Check for sharp edges and broken adjustment parts.

Repair a feeder with a sharp edge by grinding it smooth. Replace a feeder that is rusted through, has a broken adjustment mechanism, or has lost its shape.

Drinkers

Nipple drinkers wear out. The internal spring weakens and the valve no longer seals properly. A drinker that drips constantly wastes water and keeps the floor wet. A drinker that does not flow freely restricts water intake.

Repair a drinker by cleaning it or replacing the internal parts. Replace a drinker that is worn, corroded, or damaged. Most drinkers have a service life of 2 to 4 years.

Fans

Fans have a service life of 10 to 15 years with good maintenance. The motor is the most expensive component. A fan motor that is failing should be replaced, not repaired.

Replace a fan when the housing is rusted, the shutters no longer operate, or the cost of repair approaches half the cost of a new fan. A fan that is inefficient wastes electricity and does not move enough air.

Controllers

Ventilation controllers become obsolete as technology advances. A controller that cannot be calibrated or that has failed sensors should be replaced. Consider replacing a controller that is more than 10 years old, even if it still works, because newer controllers offer better control and monitoring features.

Heat Lamps and Mats

Heat lamps are consumable items. Replace bulbs as they burn out. Replace fixtures when the socket is worn, the reflector is corroded, or the cord is damaged.

Heat mats have a service life of 3 to 5 years. Replace a mat that does not heat evenly, that cycles excessively, or that has any damage to the surface or the cord.

Monitoring and Recordkeeping

A maintenance program is not complete without records. Written records help you track equipment performance, plan for replacements, and troubleshoot problems.

What to Record

Record every maintenance task you perform. Note the date, the task, and the person who did the work. For repairs, record the problem, the repair made, and the cost.

Record equipment failures. Note what failed, when it failed, and how long it took to fix. This information helps you identify patterns. If the same fan belt fails every 6 months, the problem may be a misaligned pulley, not a defective belt.

Record cleaning and disinfection events. Note the products used and the dates. This information is valuable for disease investigations.

Record temperature and ventilation observations. Note any time the room temperature was outside the target range. Note any alarm events and the response.

How to Use the Records

Review the maintenance records monthly. Look for trends. Are certain pieces of equipment failing more often? Are certain rooms harder to keep clean? Are you spending more on repairs than the equipment is worth?

Use the records to plan capital improvements. If you are replacing drinkers every year, it may be time to upgrade to a more durable model. If a fan has been repaired three times in two years, it is time to replace it.

Share the records with your veterinarian. The vet can use cleaning and disinfection records to investigate disease problems. The vet can also advise on equipment choices that support pig health.

Digital vs. Paper Records

Both paper and digital records work. Paper records are simple and do not fail in a power outage. Digital records are easier to search and analyze.

If you use paper records, keep them in a binder in the barn. Use a simple form for each room. Date and initial each entry.

If you use digital records, use a system that is easy to enter data into. A spreadsheet works. A dedicated farm management app works better. The key is to use the system consistently.

Biosecurity and Maintenance

Maintenance tasks connect directly to biosecurity. A well maintained barn is easier to keep clean and less likely to harbor disease.

Clean Between Groups

The all-in, all-out cleaning process is a biosecurity measure. It breaks the cycle of disease transmission between groups. Do not cut corners on this process.

Maintain the Perimeter

Check the barn perimeter regularly. Look for holes in the walls, gaps under doors, and damaged screens. Rodents and birds can enter through surprisingly small openings.

Keep the area around the barn clean. Remove weeds, tall grass, and debris. These attract rodents and provide cover for wildlife.

Manage Foot Traffic

Maintain footbaths and boot scrub stations. Replace the disinfectant in footbaths on schedule. A footbath with dirty, diluted disinfectant is worse than no footbath because it gives a false sense of security.

Maintain the changing area. Keep clean boots and coveralls available. Keep the area organized so that people actually use it.

Service Vehicles and Equipment

Clean and disinfect any equipment that moves between farms or between buildings. This includes trailers, loaders, and portable equipment. A loader that moves manure from one barn to another can spread disease.

Pest Control as Biosecurity

Rodents and flies are biological vectors. They carry pathogens from one area to another. An effective pest control program is a biosecurity measure.

Maintain bait stations and traps. Keep the barn free of spilled feed and other attractants. Seal entry points. Work with a pest control professional if you have a persistent problem.

When to Call a Veterinarian or Extension Agent

Most maintenance problems are straightforward. You fix them yourself or call a contractor. But some situations require professional help.

Call Your Veterinarian When

Call your veterinarian when pig health does not improve after you have corrected the obvious environmental problems. If pigs are still scouring after you fixed the ventilation and cleaned the room, you need veterinary help.

Call your veterinarian when you see patterns of disease that you cannot explain. If every litter in one farrowing room develops joint ill, the problem may be in the room. Your veterinarian can help you investigate.

Call your veterinarian when pig losses increase. A sudden increase in mortality is always a reason to call. Do not wait to see if it resolves.

Call your veterinarian when you see signs of a reportable disease. Blisters on snouts and feet, central nervous system signs, and high fever with sudden death are examples. Your veterinarian will help you determine if you need to contact regulatory authorities.

Call an Extension Agent When

Call your local extension agent when you need help with facility design or ventilation. Extension engineers can assess your ventilation system and make recommendations. They can help you balance airflow, inlet placement, and fan capacity.

Call your extension agent when you are planning a remodel or a new building. Extension specialists have resources on building design, equipment selection, and layout. They can help you avoid costly mistakes.

Call your extension agent when you want to learn about new technology. Extension programs often offer workshops and demonstrations on new equipment and management practices.

Call a Qualified Contractor When

Call a qualified electrician for any electrical work beyond simple checks. Working on live electrical panels is dangerous. A licensed electrician should handle panel upgrades, new circuits, and major wiring.

Call a qualified HVAC contractor for work on gas heaters and complex ventilation systems. Gas appliances require specialized knowledge. A mistake can cause a fire, an explosion, or carbon monoxide poisoning.

Call a qualified plumber for major plumbing work. Buried water lines, well pumps, and pressure systems require specialized equipment and knowledge.

Call a structural engineer if you see signs of building failure. Cracks in foundation walls, sagging roof trusses, and leaning walls are serious problems. Do not attempt to fix these yourself.

Frequently Asked Questions

How often should I clean a farrowing room between groups?

Clean and disinfect every farrowing room between every group. The process includes dry scraping, soaking with detergent, high pressure washing, rinsing, inspecting, disinfecting, and drying. The entire process should take 2 to 4 days per room, depending on the room size and the cleaning crew. Do not shorten the process to turn the room faster. A poorly cleaned room will cost you more in pig health problems than you save in labor.

What is the best disinfectant for a farrowing barn?

There is no single best disinfectant. Choose a disinfectant based on the disease risks on your farm and the label claims. Look for a product that is effective against the pathogens you are most concerned about. Use the product at the correct concentration and contact time. Rotate between two or three disinfectants with different active ingredients to prevent the development of resistance. Always clean thoroughly before disinfecting. Disinfectants do not work on dirty surfaces.

How do I know if my ventilation system is working properly?

Start with the pigs. Pigs that are comfortable, active, and eating well tell you the ventilation is working. Use your hand and your nose. Air should feel fresh, not stale or stuffy. You should not smell strong ammonia. Check the controller reading against a separate thermometer. Check that fans are running at the correct stages. Measure airflow at the inlets if you have the equipment. If you are unsure, call your extension agent and ask for a ventilation assessment.

Why do my heat lamps keep burning out?

Heat lamps burn out prematurely for several reasons. Vibration from the fan or the building structure can shorten bulb life. Poor quality bulbs fail faster than quality bulbs. Excessive heat buildup in the fixture can damage the bulb. Moisture can cause the bulb to fail. Check the fixture for corrosion and the cord for damage. Use a quality bulb rated for the fixture. Consider switching to heat mats or radiant heaters, which are more durable than heat lamps.

How often should I replace nipple drinkers?

Nipple drinkers wear out based on water quality, usage, and the quality of the drinker. Most drinkers last 2 to 4 years. Check each drinker daily for flow. Replace a drinker when it drips constantly, when the flow is weak, or when the internal parts are worn. Keep spare drinkers on hand so you can replace a failing drinker immediately.

What should I do if I find a broken fan belt?

Replace the fan belt as soon as you find it. A broken belt stops the fan completely. Check the pulleys for alignment and wear before you install the new belt. A misaligned pulley will destroy the new belt quickly. Keep spare belts for every fan size on the farm. Check belts weekly and replace any belt that is cracked, frayed, or stretched.

How do I prevent ammonia buildup in my nursery barn?

Ammonia comes from urine and manure breaking down. Control ammonia by removing manure regularly, keeping the room dry, and providing adequate ventilation. Scrape or flush manure on schedule. Fix leaking drinkers that keep the floor wet. Run the minimum ventilation fans continuously to remove moisture and gases. If ammonia is still high, increase the ventilation rate and review your manure removal schedule.

When should I call my veterinarian about a maintenance related problem?

Call your veterinarian when you see a pattern of pig health problems that does not respond to your corrections. Examples include repeated scours in a room that has been cleaned and disinfected, increasing joint infections in piglets, or a rise in respiratory disease in nursery pigs. Your veterinarian can help you investigate the cause, which may be in the environment, the equipment, or the management system.
