Heating and Lamps for Piglet Creep Areas
By Dr. Zubair Khalid, DVM, MS, PhD ·

Key Takeaways
- Newborn piglets require a critical ambient temperature of 90-95°F for the first week, necessitating a creep area 10-15°F warmer than the general farrowing room to compensate for their limited body fat and inability to shiver.
- Heat lamps (250-watt infrared bulbs) are common due to low cost and ease of use, but require precise placement (18-24 inches above floor) and constant monitoring of floor temperature, not air temperature, to prevent chilling or overheating.
- Draft-free creep areas are paramount; even minor air movement can negate the effectiveness of heat sources by rapidly dissipating warmth, emphasizing the need for solid barriers and careful ventilation management.
- Piglet behavior is a primary diagnostic tool: piling indicates cold stress, while spreading out and panting suggests overheating, with comfortable piglets sleeping spread but close together.
- Fire safety protocols are critical when using heat lamps, including secure mounting, wire guards, daily inspection of cords and sockets, and maintaining a safe distance from flammable bedding and materials.
- Record keeping of room and creep temperatures, lamp height, bulb wattage, and piglet health is essential for identifying trends, optimizing heat management, and preventing mortality from cold stress, crushing, or compromised colostrum absorption.
Keeping newborn piglets warm is one of the most important jobs on any swine operation. Piglets are born with very little body fat and no ability to shiver effectively, so they depend entirely on their environment to stay warm. A piglet that gets cold will not nurse well, will not absorb colostrum properly, and becomes far more likely to be crushed by the sow or to die from scours and other diseases. This guide explains how to design, set up, and manage creep areas with the right heating and lamps. It is written for swine producers, farm employees, and anyone who manages farrowing houses and wants practical, field-tested advice on piglet warmth management.
At a Glance
- Target temperature for newborn piglets: 90 to 95 degrees Fahrenheit for the first week, dropping about 5 degrees per week after that.
- Creep area temperature: Should be 10 to 15 degrees warmer than the rest of the farrowing room.
- Best heat sources: Heat lamps (250-watt infrared bulbs), heat mats, and radiant heaters. Heat lamps are the most common because they are cheap and easy to move.
- Bulb height: Hang heat lamps 18 to 24 inches above the floor for newborn piglets. Adjust up or down based on measured floor temperature.
- Critical measurement: Always measure floor temperature at piglet level, not air temperature at human height. Use a thermometer placed directly on the floor in the creep area.
- Draft protection: A draft-free creep area is just as important as the heat source. Even a small draft can make a heat lamp useless.
- Fire safety: Secure all lamps firmly. Use wire guards. Keep lamps away from bedding, sow feeders, and anything flammable. Check cords and sockets daily.
- Observe piglet behavior: Piglets piled up on top of each other means too cold. Piglets spread out far from the lamp and panting means too hot. Piglets sleeping comfortably spread out but close together means just right.
- Record keeping: Log room temperature, creep temperature, lamp height, bulb wattage, and any piglet health problems daily.
Why Piglets Need Extra Heat
Newborn piglets are biologically unprepared for the temperatures found in most farrowing rooms. A sow is comfortable at 60 to 70 degrees Fahrenheit, but a newborn piglet needs 90 to 95 degrees for at least the first few days of life. That wide gap is why you cannot simply heat the whole room to piglet temperature. The sow would suffer from heat stress, stop eating, and produce less milk. Instead, you create a warm microclimate just for the piglets, and that microclimate is called the creep area.
The Physiology of a Newborn Piglet
A piglet is born with less than 2 percent body fat. That fat is mostly brown fat, which is meant for short-term energy, not insulation. The piglet also has a large surface area relative to its body weight, which means it loses heat quickly. Its hair coat is thin and sparse. Most importantly, a newborn piglet cannot shiver. Shivering is the main way most mammals generate heat when they are cold, but piglets do not develop that ability until they are several days old. Instead, piglets rely on the heat from the sow and from their environment.
The piglet's lower critical temperature is the temperature below which it must burn energy to stay warm. For a newborn piglet, that lower critical temperature is around 90 degrees Fahrenheit. If the environment is colder than that, the piglet uses its limited energy reserves just to stay warm. That energy is diverted away from growth, from nursing, and from immune function. The result is a weaker piglet that is more likely to get sick and more likely to die.
Colostrum and Warmth
The first 24 hours of a piglet's life are critical for colostrum intake. Colostrum provides antibodies that protect the piglet from disease for the first several weeks of life. A cold piglet is a weak piglet. It cannot compete with littermates for a teat. It may not have the energy to get up and nurse at all. Even if it does nurse, a stressed and cold piglet absorbs colostrum less efficiently. This means the piglet starts life with a weaker immune system, and that disadvantage can last the entire time it is in the nursery.
The Crushing Risk
Cold piglets are also more likely to be crushed. A piglet that is cold will try to snuggle against the sow for warmth. The sow is large and can easily roll over onto a small piglet without noticing. A piglet that is warm and comfortable in the creep area is much less likely to lie next to the sow. Good piglet warmth management is one of the most effective ways to reduce pre-weaning mortality from crushing.
Designing the Creep Area
The creep area is the zone in the farrowing crate where the piglets can get away from the sow and stay warm. It needs to be designed so that piglets can find it easily and so that the sow cannot reach it. A well-designed creep area has three essential features: a heat source, a barrier that keeps the sow out but lets piglets through, and a floor surface that does not draw heat away from the piglets.
Location in the Farrowing Crate
Most farrowing crates have a heat zone on one or both sides of the sow. The creep area is typically located in a corner of the crate, behind a small panel or curtain that the sow cannot reach. The piglets can pass through gaps in the panel, but the sow's head and body are too large to fit through.
Place the heat source so that it creates a warm zone in the corner of the crate, away from the sow's udder and away from the dunging area. Piglets will naturally seek out the warmest spot in the crate, so the heat source should pull them away from the sow, not toward her.
Flooring Considerations
The floor of the creep area matters a great deal. Concrete and metal flooring are excellent conductors of heat. They will pull heat away from a piglet's belly faster than the piglet can generate it. If you are using a heat lamp, the floor directly under the lamp will be warm, but the surrounding floor may still be cold.
Options for improving the floor in the creep area include:
- Rubber mats: These provide insulation between the piglet and the cold floor. They are easy to clean and disinfect between farrowings.
- Plastic-coated expanded metal: This is warmer than bare metal or concrete and is a common choice for farrowing crate flooring.
- Straw or other bedding: Bedding provides insulation, but it can interfere with slatted floors and can harbor bacteria if not changed frequently. Use only in well-managed systems where you can keep it dry and clean.
- Heat mats: These are electric heating pads designed specifically for creep areas. They warm the floor surface directly and do not heat the air much. Heat mats are an excellent choice for piglets because they warm the belly, which is where piglets lose the most heat.
Draft Protection
A draft is moving air that carries heat away from the piglet. Even a small draft can make a heat lamp useless because the moving air strips away the warm air that the lamp creates. Check the creep area for drafts from doors, ventilation inlets, and gaps in the farrowing crate panels. Use solid panels or curtains to block drafts while still allowing air to move for ventilation.
The creep area should be warm but not stuffy. You need to balance draft protection with the need for fresh air. Stale air with high ammonia levels can cause respiratory problems in piglets and the sow. A good rule is to protect the piglets from drafts that come from below and from the sides, while allowing fresh air to enter from above.
Piglet Creep Heating Options
There are several ways to heat a creep area. Each has advantages and disadvantages. The right choice depends on your facility, your budget, your management style, and the number of sows you farrow.
Heat Lamps
Heat lamps are the most common choice for piglet creep heating. They are inexpensive to buy, simple to install, and easy to move from crate to crate. A standard setup uses a 250-watt infrared bulb in a reflector fixture, hung 18 to 24 inches above the floor.
Advantages of heat lamps:
- Low initial cost
- Easy to install and replace
- Provide both heat and light, which helps piglets find the creep area
- Easy to adjust by raising or lowering the lamp
Disadvantages of heat lamps:
- High energy use. A 250-watt bulb running continuously uses 6 kilowatt-hours per day. If you have 20 farrowing crates, that is 120 kilowatt-hours per day just for creep heating.
- Fire hazard if not installed properly
- Heat only the area directly under the lamp, so the rest of the creep area may be cold
- Bulbs burn out and need regular replacement
- Can overheat piglets if hung too low
Types of bulbs:
- Infrared bulbs: These produce both light and heat. They are the most common choice. Red bulbs are preferred by some producers because the red light is less disruptive to the sow's sleep cycle than white light.
- Clear bulbs: These produce bright light and more heat. They are not recommended for continuous use because the bright light can stress the sow and the piglets.
- Ceramic heat emitters: These produce heat without light. They are more expensive than infrared bulbs but last longer and do not disrupt the piglets' day-night cycle. Some producers prefer these for the first few days of life.
Heat Mats
Heat mats are electric pads that sit on the floor of the creep area. They warm the floor surface to a set temperature, usually around 90 to 100 degrees Fahrenheit. Piglets lie directly on the mat and stay warm from below.
Advantages of heat mats:
- Warm the piglet's belly, which is where heat loss is greatest
- Use less energy than heat lamps
- Do not create a fire hazard
- Provide consistent temperature across the mat surface
- Do not produce light, so they do not disrupt piglet sleep patterns
Disadvantages of heat mats:
- Higher initial cost than heat lamps
- Piglets must learn to lie on the mat. Some piglets will lie on the cold floor next to the mat instead.
- Can be damaged by the sow if she can reach them
- Require careful cleaning and inspection for damage to the heating element
Radiant Heaters
Radiant heaters, also called radiant brooder heaters, are mounted overhead and direct heat downward. They are similar to heat lamps but use a different heating element and are often more energy efficient. Some radiant heaters use gas, while others use electricity.
Advantages of radiant heaters:
- Heat a larger area than a heat lamp
- More energy efficient than heat lamps
- Provide even heat distribution
Disadvantages of radiant heaters:
- Higher initial cost
- More complex installation
- May require professional installation for gas models
- Can be overkill for small operations
Whole-Room Heating
Some producers choose to heat the entire farrowing room to a temperature that is comfortable for piglets, usually around 85 to 90 degrees, and then use fans to keep the sows cool. This approach is more common in older facilities or in very cold climates. It is expensive because heating a whole room is much less efficient than heating a small creep area. It also puts the sows at risk of heat stress, which can reduce feed intake and milk production.
Whole-room heating alone is rarely the best approach. A better strategy is to keep the room at a temperature that is comfortable for the sow, around 65 to 70 degrees, and use creep heating to create a warm zone for the piglets.
Comparing the Options
| Heating Option | Initial Cost | Operating Cost | Heat Distribution | Fire Risk | Best For |
|---|---|---|---|---|---|
| Heat lamp (250W) | Low | High | Small, focused zone | Moderate | Small to medium operations |
| Heat mat | Medium | Low | Even across mat surface | Low | Operations of any size |
| Radiant heater | High | Medium | Larger zone | Low to moderate | Larger operations |
| Whole-room heating | High | Very high | Whole room | Low | Older facilities, cold climates |
Step-by-Step Setup for Heat Lamps
Heat lamps are the most common choice, so this section covers the step-by-step process for setting them up correctly. The same principles apply to other heat sources, but the specific instructions are for heat lamps.
Step 1: Gather Your Equipment
You will need the following items for each farrowing crate:
- One 250-watt infrared heat lamp bulb (red or clear)
- One reflector fixture with a porcelain socket
- One wire guard to protect the bulb from breakage and to prevent piglets from touching the hot bulb
- A secure method for hanging the lamp, such as a chain, rope, or adjustable bracket
- A thermometer that can measure floor temperature at piglet level
Step 2: Position the Lamp
Hang the lamp so that the bottom of the bulb is 18 to 24 inches above the floor. This is the starting point for newborn piglets. The exact height will depend on the wattage of the bulb, the ambient room temperature, and the type of floor. Use the thermometer to check the floor temperature directly under the lamp and adjust the height until you achieve 90 to 95 degrees at floor level.
Position the lamp in the corner of the creep area, as far from the sow as possible while still being within the creep zone. The goal is to pull the piglets away from the sow, not to heat the sow.
Step 3: Install the Wire Guard
A wire guard is essential. Without it, a piglet can jump up and touch the hot bulb, causing a burn. The guard also protects the bulb from breaking if something falls against it. A broken bulb can start a fire or cut a piglet. Secure the guard firmly to the reflector so that it cannot be knocked loose.
Step 4: Secure the Lamp
Secure the lamp so that it cannot swing or fall. A lamp that swings can hit the sow or the crate. A lamp that falls to the floor can start a fire or burn a piglet. Use a chain or rope that is rated for the weight of the fixture. Check the hanging system daily to make sure it is still secure.
If you are using an adjustable bracket, make sure the locking mechanism is tight. Some producers use a simple hook and chain system, which allows for easy height adjustment. Whatever system you use, make sure it cannot be knocked loose by the sow.
Step 5: Check the Electrical Connection
Plug the lamp into a grounded outlet. Use a heavy-duty extension cord if needed, but keep the cord as short as possible. Check the cord for fraying or damage before each use. Make sure the cord is not lying on the floor where the sow can step on it or where moisture can reach it. Hang the cord out of reach of the sow and piglets.
Use a ground fault circuit interrupter (GFCI) outlet for all electrical equipment in the farrowing house. This protects against electrical shock if moisture gets into the system.
Step 6: Measure the Temperature
Place a thermometer on the floor of the creep area, directly under the heat lamp. Leave it for at least 10 minutes to get an accurate reading. The floor temperature should be 90 to 95 degrees for newborn piglets. If it is too cold, lower the lamp by 2 to 3 inches and recheck. If it is too hot, raise the lamp by 2 to 3 inches and recheck.
Remember that the temperature at floor level is what matters, not the temperature at your waist or head height. A room that feels comfortable to you can still be too cold for a piglet on the floor.
Step 7: Observe Piglet Behavior
After the lamp is set, watch the piglets for a few minutes. Their behavior will tell you if the temperature is right.
- Too cold: Piglets pile up on top of each other directly under the lamp. They are noisy and restless. They may try to burrow under the sow.
- Too hot: Piglets spread out as far from the lamp as possible. They lie flat on their sides and may pant. They may try to move out of the creep area entirely.
- Just right: Piglets sleep comfortably, spread out but close together. They are quiet and relaxed. They move in and out of the creep area freely to nurse.
Step 8: Adjust as Piglets Grow
As piglets grow, they need less heat. At one week of age, lower the floor temperature to about 85 degrees. At two weeks, lower it to about 80 degrees. You can achieve this by raising the lamp by 2 to 3 inches each week, or by switching to a lower wattage bulb.
Some producers use a timer or a thermostat to reduce heat output as the piglets grow. This saves energy and reduces the risk of overheating older piglets.
Setting Up Heat Mats
Heat mats are a good alternative to heat lamps, especially for operations that want to reduce energy costs and fire risk. The setup is simpler than for heat lamps, but there are still important considerations.
Step 1: Choose the Right Mat
Select a heat mat that is rated for use with piglets. The mat should be large enough to accommodate the entire litter. A typical mat is about 24 inches by 36 inches, but you may need a larger mat for large litters. Make sure the mat has a thermostat or a temperature control so you can set it to the correct temperature.
Step 2: Place the Mat
Place the mat on the floor of the creep area, away from the sow's reach. The mat should be flat and secure. Some mats have non-slip backing, which helps keep them in place. If the mat slides around, secure it with clips or tape.
Step 3: Connect the Power
Plug the mat into a GFCI outlet. Check the cord for damage before each use. Make sure the cord is routed so that the sow cannot chew on it or step on it.
Step 4: Set the Temperature
Set the mat temperature to 90 to 95 degrees for newborn piglets. Use a thermometer to verify the surface temperature of the mat. Adjust the thermostat as needed.
Step 5: Encourage Piglets to Use the Mat
Piglets may not immediately understand that the mat is a warm place to lie. You can encourage them by scattering a little feed or some clean straw on the mat. Some producers place a small amount of the sow's feces on the mat to attract piglets, but this is not recommended because it can spread disease. A better approach is to gently place piglets on the mat after they have nursed. They will quickly learn that the mat is a comfortable place to sleep.
Step 6: Monitor and Adjust
Check the mat daily for signs of damage. Look for cracks in the surface, exposed wires, or areas that are not heating evenly. If you find any damage, replace the mat immediately. A damaged mat can cause electrical shock or burns.
Common Mistakes in Piglet Creep Heating
Even experienced producers make mistakes with creep heating. Here are the most common problems and how to avoid them.
Mistake 1: Hanging the Lamp Too High
Many producers hang the lamp too high to reduce the risk of burns or to save energy. The result is that the floor temperature is too low and the piglets are cold. Always measure the floor temperature with a thermometer rather than guessing. A lamp that is hung too high wastes energy because it heats the air instead of the piglets.
Mistake 2: Hanging the Lamp Too Low
The opposite problem is hanging the lamp too low. This can overheat the piglets and cause burns. It also increases the fire risk. If the lamp is close enough to the floor that you can feel significant heat when you put your hand at floor level, it is probably too low. Use the thermometer to get the exact temperature.
Mistake 3: Ignoring Drafts
A heat lamp in a drafty area is nearly useless. The moving air carries the heat away before the piglets can benefit from it. Check for drafts from doors, windows, ventilation fans, and gaps in the crate panels. Block drafts with solid panels or curtains.
Mistake 4: Using the Wrong Bulb
Not all heat bulbs are the same. A 125-watt bulb produces much less heat than a 250-watt bulb. In a cold room, a 125-watt bulb will not be sufficient. Conversely, in a warm room, a 250-watt bulb may be too much. Match the bulb wattage to the ambient room temperature and the age of the piglets.
Mistake 5: Not Adjusting as Piglets Grow
Piglets need less heat as they get older. A lamp that is set correctly for newborns will be too hot for two-week-old piglets. Adjust the lamp height or switch to a lower wattage bulb as the piglets grow. This saves energy and keeps the piglets comfortable.
Mistake 6: Ignoring Fire Safety
Heat lamps are a leading cause of barn fires. The combination of a hot bulb, flammable dust, and dry bedding is dangerous. Always use a wire guard. Keep the lamp away from bedding, curtains, and other flammable materials. Check cords and sockets daily. Never leave a heat lamp running unattended in an empty crate.
Mistake 7: Not Measuring Floor Temperature
Many producers set the lamp height once and never check it again. But the floor temperature changes with the ambient room temperature, the age of the piglets, and the condition of the bulb. Measure the floor temperature at least once a day, preferably at the same time each day.
Mistake 8: Overlooking the Sow
The sow also needs to be comfortable. If the creep area is too hot, the sow may choose to lie in the creep area, crushing piglets. If the room is too cold, the sow may be uncomfortable and eat less. Balance the needs of the sow and the piglets by keeping the room at 65 to 70 degrees and using the creep area to provide the extra warmth piglets need.
Monitoring and Recordkeeping
Good recordkeeping is essential for managing creep heating effectively. Without records, you are guessing. With records, you can identify trends, spot problems early, and make informed decisions.
What to Record
For each farrowing crate, record the following daily:
- Room temperature: The temperature of the farrowing room at sow level.
- Creep area temperature: The floor temperature in the creep area at piglet level.
- Lamp height or thermostat setting: How high the lamp is hung or where the thermostat is set.
- Bulb wattage or mat temperature: What heat source you are using and its output.
- Number of piglets: How many piglets are in the litter.
- Piglet behavior: Whether the piglets are piling, spreading out, or sleeping comfortably.
- Any health problems: Scours, crushing, weakness, or other issues.
- Any equipment problems: Burned out bulbs, damaged cords, malfunctioning thermostats.
How to Use the Records
Review your records weekly. Look for patterns. Are piglets in certain crates consistently colder than in others? Is there a draft from a particular door that shows up in the records? Are piglets in a certain part of the room more likely to have health problems?
Use the records to make adjustments. If the creep temperature is consistently too low in a particular crate, check for drafts or move the lamp lower. If piglets are consistently too hot, raise the lamp or switch to a lower wattage bulb.
Records also help you plan for the future. If you are spending a lot on electricity for heat lamps, the records will show it. You can then decide whether investing in heat mats or radiant heaters would pay off.
Daily Checklist
Use this checklist every day in the farrowing house:
- Check the room temperature and adjust ventilation if needed.
- Check the floor temperature in each creep area.
- Check each heat lamp for proper height, secure hanging, and working bulb.
- Check each cord for damage and make sure it is out of reach of the sow.
- Check for drafts from doors, windows, and ventilation inlets.
- Observe piglet behavior in each crate. Look for piling, panting, or other signs of temperature stress.
- Check for any piglets that are weak, shivering, or separated from the litter.
- Clean any soiled areas in the creep area.
- Record all observations in your log.
Energy Efficiency and Cost Management
Heating a farrowing house is expensive. Heat lamps are one of the biggest energy users in swine production. Here are some strategies to reduce energy costs without compromising piglet comfort.
Use the Right Wattage
A 250-watt bulb is standard, but it is not always necessary. In a well-insulated room with good draft protection, a 125-watt bulb may be sufficient for older piglets. Use the lowest wattage that maintains the correct floor temperature. The thermometer is your guide.
Use Thermostats and Timers
A thermostat can control the heat lamp or heat mat so that it only runs when the temperature drops below the set point. This can save a significant amount of energy, especially in milder weather. Timers can be used to reduce heat output during the warmest part of the day.
Group Farrowing
If you can group your sows so that they farrow at the same time, you can heat the entire farrowing room more efficiently. Instead of heating 20 individual creep areas, you can raise the room temperature for a short period and use less supplemental heat.
Insulate the Building
Good insulation reduces heat loss and makes the entire heating system more efficient. Check the insulation in the walls and ceiling of the farrowing house. Seal any gaps around doors and windows. A well-insulated building pays for itself in reduced energy costs.
Use Heat Mats Where Possible
Heat mats are significantly more energy efficient than heat lamps. A heat mat uses about 60 to 100 watts, compared to 250 watts for a heat lamp. Over a three-week lactation period, the savings can be substantial. If you are building a new facility or replacing equipment, consider heat mats as the primary heat source.
Consider Radiant Tube Heaters
Radiant tube heaters are more efficient than heat lamps because they heat the floor and the piglets directly, rather than heating the air. They also have a longer lifespan than heat lamps. The initial cost is higher, but the operating cost is lower over time.
When to Call a Veterinarian or Extension Agent
Most creep heating problems can be solved with basic management. However, there are times when you should call a veterinarian or your local extension agent for help.
Call a Veterinarian If:
- You see an unusual number of piglets dying in the first few days of life, even though the temperatures appear correct.
- Piglets are shivering or cold even when the floor temperature is in the correct range. This could indicate a health problem that affects the piglet's ability to regulate body temperature.
- You see a pattern of scours or diarrhea that does not respond to standard treatment. Cold stress can make piglets more susceptible to disease, but persistent disease may have another cause.
- Piglets are weak, unable to stand, or failing to nurse even when the creep area is warm.
- You suspect that the sow has a health problem that is affecting her milk production or her behavior toward the piglets.
Call an Extension Agent If:
- You are designing a new farrowing facility and need advice on the best heating system for your situation.
- You want to compare the costs and benefits of different heating options.
- You are experiencing high energy costs and want to improve efficiency.
- You need help developing a recordkeeping system for your farrowing house.
- You want to learn about new technologies or management practices for piglet warmth management.
Questions to Ask When You Call
When you call a veterinarian or extension agent, be prepared with the following information:
- The number of sows in your herd and the number of sows farrowing at any one time.
- The type of farrowing facility you have, including the type of flooring and the ventilation system.
- The heating system you are currently using and how it is set up.
- Your recent records of room temperature, creep temperature, and piglet health.
- Any changes you have made recently, such as new equipment, new feed, or new management practices.
Advanced Considerations
Temperature Gradients Within the Creep Area
The temperature is not uniform across the creep area. It is warmest directly under the heat lamp and cooler at the edges. This gradient is actually useful because it allows piglets to choose their preferred temperature. A piglet that is too warm can move to the edge of the creep area. A piglet that is too cold can move directly under the lamp. This is one reason why heat lamps are so effective: they create a range of temperatures that lets piglets self-regulate.
When you set up a heat lamp, make sure the gradient is not too extreme. If the area directly under the lamp is 100 degrees and the edge of the creep area is 70 degrees, the piglets have a 30-degree range to choose from. That is too wide. The piglets at the edge will be cold. Aim for a gradient of about 10 degrees from directly under the lamp to the edge of the creep area.
The First 24 Hours
The first 24 hours after birth are the most critical for piglet survival. During this time, the piglets are learning to nurse, absorbing colostrum, and adjusting to life outside the womb. They are also at the highest risk of chilling.
For the first 24 hours, set the creep temperature at the high end of the range, around 95 degrees. Check the temperature every few hours and make adjustments as needed. Watch the piglets closely. If they are piling, they need more heat. If they are panting, they need less.
After the first 24 hours, you can gradually reduce the temperature by about 1 degree per day for the first week, then more quickly as the piglets grow and develop the ability to regulate their own body temperature.
Seasonal Adjustments
Creep heating needs change with the seasons. In the summer, the ambient room temperature may be close to the target creep temperature, so you may only need a small amount of supplemental heat. In the winter, the room may be cold and drafty, requiring more heat output.
Adjust your heating strategy seasonally. In the summer, you may be able to use lower wattage bulbs or raise the lamps higher. In the winter, use full wattage and check for drafts more carefully. Also consider that ventilation needs change with the seasons. In the summer, you may need more ventilation to keep the sow cool, but too much ventilation can create drafts in the creep area. Balance ventilation needs with draft protection.
Large Litters
Large litters, especially those with more than 12 piglets, present special challenges for creep heating. The piglets need more space in the creep area, and the heat source needs to cover a larger area. A single heat lamp may not be sufficient for a very large litter. You may need two lamps or a larger heat mat.
With large litters, also watch for piglets that are pushed to the edge of the creep area and cannot get close to the heat source. These piglets may be at risk of chilling. Provide a larger creep area or add a second heat source to ensure all piglets have access to warmth.
Small or Weak Piglets
Small or weak piglets need extra attention. They have less body fat and less energy than their littermates, so they are more susceptible to chilling. You may need to provide extra heat for these piglets, or you may need to place them in a separate, warmer area until they are strong enough to compete with their littermates.
Some producers use a "hospital pen" or a separate box with a heat lamp for weak piglets. This allows the weak piglets to recover without competition from stronger littermates. Check on these piglets frequently and return them to the sow when they are strong enough to nurse effectively.
Creep Area Cleanliness
The creep area must be kept clean and dry. A wet or soiled creep area is colder than a dry one because moisture conducts heat away from the piglet. It also promotes bacterial growth and disease.
Clean the creep area daily. Remove soiled bedding and replace it with clean, dry material. If you are using heat mats, wipe them down with a disinfectant. If you are using heat lamps, make sure the reflector and guard are clean so that heat can pass through effectively.
Fire Prevention
Fire prevention is a critical part of creep heating management. Heat lamps are one of the most common causes of barn fires. Follow these rules to reduce the risk:
- Use a wire guard on every heat lamp.
- Hang lamps securely so they cannot fall.
- Keep lamps at least 18 inches away from any flammable material, including bedding, curtains, and feed bags.
- Check cords and sockets daily for damage.
- Use GFCI outlets for all electrical equipment.
- Do not use extension cords unless absolutely necessary, and use only heavy-duty cords rated for the wattage of the lamp.
- Never leave a heat lamp running in an empty crate.
- Keep a fire extinguisher in the farrowing house and make sure all employees know how to use it.
- Have a plan for evacuating animals in case of fire.
Frequently Asked Questions
What is the ideal piglet heat lamp temperature for newborn piglets?
The ideal floor temperature in the creep area for newborn piglets is 90 to 95 degrees Fahrenheit for the first week of life. This is the temperature at the floor, not at human height. Use a thermometer placed directly on the floor under the heat lamp to measure it. After the first week, you can reduce the temperature by about 5 degrees per week as the piglets grow and develop the ability to regulate their body temperature.
How high should I hang a heat lamp above piglets?
For a standard 250-watt infrared heat lamp, hang the bottom of the bulb 18 to 24 inches above the floor for newborn piglets. This is a starting point. Always verify with a thermometer at floor level and adjust the height until you achieve 90 to 95 degrees. If the floor is too cold, lower the lamp by 2 to 3 inches. If the floor is too hot, raise the lamp by 2 to 3 inches. Recheck the temperature after each adjustment.
What are the best creep area heating options for a small farrowing operation?
For a small operation, the best options are heat lamps or heat mats. Heat lamps are the cheapest to buy and easiest to install. They are ideal if you have only a few farrowing crates and want a simple, flexible solution. Heat mats cost more upfront but use less electricity and are safer because they do not create a fire hazard. If you are concerned about energy costs or fire risk, heat mats are the better choice. For small operations, either option works well. The key is to measure the floor temperature and adjust the heat source based on the piglets' behavior.
How can I tell if my piglets are too cold or too hot?
Watch the piglets' behavior. If they are too cold, they will pile up on top of each other directly under the heat lamp. They will be noisy, restless, and may try to burrow under the sow. If they are too hot, they will spread out as far from the lamp as possible, lie flat on their sides, and may pant. If the temperature is just right, the piglets will sleep comfortably, spread out but close together. They will be quiet and relaxed, and they will move freely between the creep area and the sow to nurse.
Can I use a regular household light bulb for piglet heating?
No. Regular household light bulbs do not produce enough heat for piglets. They also produce bright light that can stress the sow and piglets. Use only infrared heat bulbs or ceramic heat emitters rated for animal use. A 250-watt infrared bulb is the standard choice for piglet creep areas. These bulbs are designed to produce heat efficiently and are available at farm supply stores.
How much electricity does a heat lamp use?
A 250-watt heat lamp running continuously uses 6 kilowatt-hours per day. If you have 20 farrowing crates with a lamp in each, that is 120 kilowatt-hours per day. At an electricity rate of 15 cents per kilowatt-hour, that is 18 dollars per day just for creep heating. Over a typical 21-day lactation period, that is 378 dollars per farrowing group. This is why energy efficiency is important. Using thermostats, timers, and heat mats can significantly reduce these costs.
When should I turn off the heat lamp in the creep area?
Do not turn off the heat lamp abruptly. Reduce the heat gradually as the piglets grow. At one week of age, lower the floor temperature to about 85 degrees. At two weeks, lower it to about 80 degrees. You can achieve this by raising the lamp or switching to a lower wattage bulb. Most producers keep some heat in the creep area until weaning, even if it is just a low level of supplemental heat. The piglets will use the warm area to sleep comfortably, which helps them grow and stay healthy.
What should I do if the heat lamp keeps burning out?
If you are replacing heat lamp bulbs frequently, check the following: first, make sure you are using the correct wattage for the fixture. A fixture rated for 250 watts will overheat if you use a higher wattage bulb. Second, check the socket for corrosion or damage. A damaged socket can cause the bulb to burn out quickly. Third, check the voltage at the outlet. If the voltage is too high or too low, it can shorten bulb life. Fourth, consider the vibration level in the farrowing house. Constant vibration from fans or equipment can cause the filament to break. If you have checked all of these and the problem continues, consider switching to heat mats, which do not have bulbs to replace.
