Farrowing Crate Dimensions and Sow Comfort Design Guide

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

Key Takeaways

Optimal farrowing crate width is determined by the sow's hip width plus 2 to 4 inches (5 to 10 cm) of clearance, preventing injury and allowing comfortable lying/standing while restricting full turns. Standard inside widths range from 22 to 26 inches (56 to 66 cm), with adjustable models offering a broader range (18 to 30 inches / 46 to 76 cm) for individual sow fitting.
Crate length should accommodate the sow's ability to stand fully extended and lie flat, typically 72 to 84 inches (183 to 213 cm) total length, to prevent joint stiffness and diagonal lying which compromises piglet safety.
Piglet safety is paramount, with creep areas of 8 to 12 inches (20 to 30 cm) on each side providing a protected zone, and bar spacing of 1.5 to 2 inches (3.8 to 5 cm) vertically allowing piglet passage while preventing entrapment.
Sow comfort is influenced by flooring (plastic-coated expanded metal preferred for traction and drainage), temperature (60-70°F / 16-21°C for sows, 90-95°F / 32-35°C for piglets in creep areas), and access to water and feed.
Crate replacement should be considered when structural integrity is compromised by rust, adjustment mechanisms fail, or when sows consistently exceed 90% of the crate width, indicating a need for larger or adjustable dimensions.

Farrowing crates are the most debated piece of equipment in swine production. Get the dimensions wrong and you face crushed piglets, stressed sows, and higher labor demands. Get them right and you create a system where the sow can stand, lie down, and nurse without injury, while piglets have a safe zone that keeps them out of harm's way. This guide covers the full range of farrowing crate dimensions, sow comfort design principles, and practical steps for adjusting your setup to fit your herd. It is written for commercial pork producers, independent farmers, farm managers, and agricultural students who need concrete numbers and actionable guidance, not theory.

At a Glance

Standard crate width: 22 to 26 inches (56 to 66 cm) inside measurement for most sows
Standard crate length: 72 to 84 inches (183 to 213 cm) total
Adjustable width models: 18 to 30 inches (46 to 76 cm) range, adjusted via side panels or ratcheting mechanisms
Creep area width: 8 to 12 inches (20 to 30 cm) on each side of the sow
Bar spacing: 1.5 to 2 inches (3.8 to 5 cm) vertical bars, 9 to 10 inches (23 to 25 cm) horizontal opening for piglet passage
Sow comfort indicators: lying time, posture changes, skin lesions, lameness, and nursing behavior
Critical safety rule: never adjust a crate with a sow inside
Replacement trigger: consider replacing crates when sows consistently exceed 90 percent of the width or when rust compromises structural integrity

Why Farrowing Crate Dimensions Matter

The farrowing crate exists to solve one problem: sows accidentally crushing their piglets. Before crates became standard, sows in open pens crushed between 15 and 30 percent of piglets born alive. With properly designed crates, that number drops to 5 to 10 percent. The crate confines the sow enough that she cannot flop down suddenly or roll fully onto her side, while giving piglets an escape route.

But the crate is not just a safety device. It is also the sow's home for three to four weeks. She eats, drinks, sleeps, and nurses inside that space. If the crate is too narrow, she develops shoulder sores and joint problems. If it is too wide, she can turn around or lie diagonally, which defeats the safety purpose. If the bars are spaced wrong, piglets get trapped or the sow injures herself on the metal.

The dimensions you choose affect every performance metric that matters on a pig farm: preweaning mortality, sow body condition score at weaning, days to next estrus, and labor time per sow. A crate that fits the sow properly reduces stress, which reduces cortisol levels, which improves milk letdown and piglet growth. A crate that does not fit creates a cascade of problems that show up weeks later in the breeding barn.

Sow Anatomy and Space Requirements

To set farrowing crate dimensions correctly, you need to understand the sow's body. A mature sow at farrowing weighs between 400 and 600 pounds (181 to 272 kg). Her body condition varies by parity, genetics, and feeding program. A first-parity gilt is smaller and narrower than a fourth-parity sow. A sow carrying a large litter has a wider abdomen than one carrying a small litter.

Measure the sow at her widest point, which is usually the hips or the rear flank. Use a flexible tape measure around the widest circumference, then divide by pi (3.14) to get the approximate width. A 500-pound sow typically measures 18 to 20 inches (46 to 51 cm) across the hips. A 600-pound sow measures 20 to 22 inches (51 to 56 cm).

The crate width must be 2 to 4 inches (5 to 10 cm) wider than the sow's hip width. This gives her room to lie down and stand up without scraping against the bars, but not enough room to turn around. A sow that can turn around in her crate will do so, and that creates a dangerous situation for piglets and increases the risk of the sow getting stuck.

Height is less critical than width and length, but it still matters. The top bar of the crate should be 36 to 42 inches (91 to 107 cm) from the floor. This allows the sow to stand fully without hitting her back, while keeping her from climbing over. The bottom bar should be 6 to 10 inches (15 to 25 cm) from the floor, low enough to prevent piglets from crawling under but high enough to allow manure and debris to pass through.

Standard Farrowing Crate Dimensions

The industry has settled on a range of standard dimensions that work for most commercial herds. These numbers come from decades of practical experience and equipment manufacturer specifications, not from a single regulatory standard.

Width

Inside width is the distance between the two side panels where the sow stands. The standard range is 22 to 26 inches (56 to 66 cm). Narrow crates at 22 inches suit gilts and smaller sows. Wide crates at 26 inches suit mature sows and heavy breeds. Most commercial crates are adjustable within this range, allowing you to match the crate to the sow.

If the crate is too narrow, the sow cannot lie down comfortably. She will spend more time standing, which increases the risk of crushing piglets when she finally lies down. She may also develop pressure sores on her hips and shoulders from rubbing against the bars. If the crate is too wide, she can turn around, and she may lie diagonally, which blocks the creep area and increases crushing risk.

Length

Total length includes the sow area plus the front gate and rear gate. The sow area itself is typically 60 to 72 inches (152 to 183 cm). The front gate adds 6 to 10 inches (15 to 25 cm), and the rear gate adds 6 to 10 inches. Total crate length runs 72 to 84 inches (183 to 213 cm).

A sow needs enough length to stand fully extended and to lie flat without her head pressed against the front gate or her rear against the back gate. If the crate is too short, she cannot stretch out, which causes joint stiffness and increases the time she spends standing. If the crate is too long, she can lie at an angle, which reduces the effective safety of the side bars.

Height

Most crates have a top rail at 36 to 42 inches (91 to 107 cm). This is high enough to contain the sow but low enough for workers to reach over and handle piglets. The bottom rail sits at 6 to 10 inches (15 to 25 cm) from the floor. The space between the bottom rail and the floor allows manure to pass through for cleaning but is small enough to keep piglets from escaping.

Bar Spacing

Vertical bars on the sides of the crate should be spaced 1.5 to 2 inches (3.8 to 5 cm) apart. This spacing prevents the sow from catching her legs between bars while allowing piglets to pass through to the creep area. Horizontal bars, if used, should have a 9 to 10 inch (23 to 25 cm) opening between the bottom rail and the first horizontal bar. This opening lets piglets move freely between the sow area and the creep area while keeping the sow confined.

The rear gate bars should be spaced 4 to 6 inches (10 to 15 cm) apart. This allows the sow's rear to be accessible for cleaning and observation while keeping her contained. The front gate should have a feed trough opening that is 12 to 16 inches (30 to 41 cm) wide and 10 to 12 inches (25 to 30 cm) high, sized to fit the sow's head comfortably.

Adjustable Farrowing Crate Systems

Fixed-width crates are cheaper and simpler, but they force you to match the crate to the average sow. Adjustable crates let you fit each sow individually, which improves comfort and reduces injury. The extra cost of an adjustable system is often recovered in reduced culling and lower mortality.

Types of Adjustable Systems

Ratcheting side panels: The most common adjustable system. One side panel is fixed, and the other moves in and out using a ratcheting mechanism. You can adjust the width from outside the crate without entering the sow area. This is the safest and easiest system to use.

Sliding panels with pins: Both side panels can move, and you secure them with pins at set intervals. This system is cheaper than ratcheting but requires you to enter the crate area to adjust, which is more dangerous.

Hydraulic or pneumatic systems: Used in large commercial operations. These allow width adjustment with a lever or button, but they are expensive and require maintenance. They are rarely justified for operations under 500 sows.

How to Adjust for Individual Sows

Set the crate width before the sow enters. Do not try to adjust the crate with a sow inside. This is a serious safety hazard for both you and the animal.

Measure the sow's hip width with a flexible tape measure while she is in the gestation barn.
Add 2 to 4 inches (5 to 10 cm) to that measurement to get your target crate width.
Adjust the crate to the target width before moving the sow into the farrowing room.
Observe the sow for the first 24 hours after she enters the crate.
If she seems cramped, adjust the crate wider before she farrows. If she has too much room and seems likely to turn, narrow it slightly.

For gilts, start with the narrow end of the range, around 20 to 22 inches (51 to 56 cm). For mature sows, start at 24 to 26 inches (61 to 66 cm). Adjust up or down based on the individual animal.

When Adjustable Crates Are Worth the Cost

Adjustable crates cost 20 to 40 percent more than fixed-width crates. They are worth the investment when:

You have a mixed parity herd with gilts and mature sows farrowing in the same room
You are buying new equipment and plan to keep it for 10 years or more
You have a history of shoulder sores or lameness in your farrowing room
You are trying to reduce culling rates in older sows

They are not worth the cost if you have a uniform herd where all sows fall within a narrow weight range, or if you are on a tight budget and can manage with fixed-width crates sized to your average sow.

Sow Comfort Design Principles

Dimensions are only part of the equation. How the crate is designed and installed affects sow comfort just as much as the numbers. A crate with perfect dimensions but a slippery floor, sharp edges, or poor ventilation will still cause problems.

Flooring

The floor is the surface the sow stands and lies on for 24 hours a day. It must provide traction, drainage, and comfort. Plastic-coated expanded metal is the most common choice. It provides good traction, is easy to clean, and does not conduct heat away from the sow as quickly as bare metal. Concrete floors with a roughened surface work well but are harder to keep clean. Fully slatted floors allow manure to fall through, which keeps the crate cleaner but can cause leg injuries if the slats are too wide or have sharp edges.

Slat width should be 4 to 5 inches (10 to 13 cm) with gaps of 0.75 to 1 inch (1.9 to 2.5 cm). Wider gaps can trap hooves and cause leg injuries. Narrower gaps do not allow enough manure to pass through, which leads to dirty crates and increased disease pressure.

Mats and Bedding

A rubber mat in the sow area reduces pressure on the sow's shoulders and hips. This is especially important for older sows and for operations that do not use bedding. The mat should cover the full width of the sow area and extend from the front gate to about two-thirds of the way to the rear gate. Leave the rear third uncovered so manure falls through the slats.

If you use bedding, choose straw or wood shavings. Bedding provides cushioning and warmth, but it complicates manure handling and can increase dust levels. Many operations use bedding only in the creep area and leave the sow area bare.

Temperature and Ventilation

Sows in farrowing crates cannot move to find a comfortable temperature. You must control the environment for them. The ideal temperature for a lactating sow is 60 to 70 degrees Fahrenheit (16 to 21 degrees Celsius). Above 75 degrees, the sow reduces feed intake, which reduces milk production and increases weight loss. Above 85 degrees, she may stop eating entirely and her body temperature rises to dangerous levels.

Piglets need the opposite: 90 to 95 degrees Fahrenheit (32 to 35 degrees Celsius) for the first week. This is why the creep area has a heat lamp or heating pad. The temperature difference between the sow area and the creep area is one of the most important design features of a farrowing crate. The creep area must be warm enough for piglets while the sow area stays cool enough for the sow.

Ventilation must remove ammonia, carbon dioxide, and moisture from the crate area. Aim for air movement of 20 to 40 cubic feet per minute per sow in cool weather and 100 to 200 cubic feet per minute in hot weather. Inlet vents should be positioned to move air across the sow's head, not directly onto her body.

Water and Feed Access

The sow needs constant access to fresh water. A nipple drinker should be positioned at the front of the crate, 24 to 30 inches (61 to 76 cm) from the floor, angled downward at 15 degrees. Flow rate should be 2 to 4 quarts per minute. Sows drink 4 to 6 gallons per day during lactation, more in hot weather.

The feed trough should be removable for cleaning and refilling. It should be 12 to 16 inches (30 to 41 cm) wide, 10 to 12 inches (25 to 30 cm) deep, and positioned so the sow can reach it without straining. The top edge of the trough should be 12 to 16 inches (30 to 41 cm) above the floor, depending on the height of the sow.

Creep Area Design

The creep area is the piglet safety zone on each side of the sow. It must be large enough for the litter to lie down together but small enough to keep them away from the sow when she lies down. Each creep area should be 8 to 12 inches (20 to 30 cm) wide and run the full length of the sow area.

The creep area is divided into two zones: the lying zone and the elimination zone. Piglets naturally separate their sleeping area from their waste area. The lying zone should have a heat source and a solid floor or mat. The elimination zone should have slatted flooring to allow waste to fall through. This design reduces the need for daily cleaning and keeps piglets healthier.

Step-by-Step Guide to Setting Up Your Farrowing Crate

Follow these steps to set up a farrowing crate that balances sow comfort with piglet safety.

Step 1: Measure Your Sows

Before you buy or adjust crates, know your sow population. Measure 20 to 30 sows across all parities in your herd. Record hip width, body weight, and parity. This gives you the range of sizes you need to accommodate.

If your sows range from 16 to 22 inches (41 to 56 cm) in hip width, you need crates that adjust from 20 to 26 inches (51 to 66 cm). If your sows are uniform at 18 to 19 inches (46 to 48 cm), fixed-width crates at 22 inches will work for most of the herd.

Step 2: Choose the Right Crate Type

Match the crate type to your herd and your management style.

Fixed-width crates: Choose this if your herd is uniform and you want the lowest equipment cost. Size them to your largest sows, not your average sow.
Adjustable crates with ratcheting panels: Choose this if you have mixed parities or a history of shoulder sores. The extra cost is justified by reduced injuries and longer sow life.
Free-access or loose-housing systems: Choose this if you are transitioning to group farrowing or if your market requires higher welfare standards. These systems are more complex and require more management skill.

Step 3: Position the Crate in the Room

The crate should face the center aisle or a service aisle so you can access the front gate for feeding and the rear gate for cleaning. Leave 3 to 4 feet (0.9 to 1.2 m) of aisle space between rows of crates so you can move a sow in or out with a sorting panel.

The rear of the crate should be 6 to 12 inches (15 to 30 cm) from the back wall. This gives you access to the sow's rear for cleaning and observation. The front should be close enough to the front aisle that you can reach the feed trough without entering the crate.

Step 4: Install Flooring and Mats

Install the flooring before you place the crates. Check that slats are level and gaps are uniform. If you are using mats, place them in the sow area after the crate is installed. The mat should fit snugly against the side panels so the sow cannot get a hoof under the edge.

Step 5: Set the Width for Each Sow

Using your sow measurements, set the width for each crate before the sow enters. Write the target width on a card or whiteboard at each crate so all workers know the setting. Recheck the width after the sow enters and adjust if needed.

Step 6: Test the Adjustment Mechanism

If you have adjustable crates, test the mechanism before each farrowing group. A ratcheting panel that sticks or a pin that will not seat is a safety hazard. Lubricate moving parts and replace worn pins or springs before they fail.

Step 7: Set Up the Creep Area

Install heat lamps or heating pads in the creep area 24 hours before the sow farrows. Set the temperature to 90 to 95 degrees Fahrenheit (32 to 35 degrees Celsius). Check that the heat source is securely mounted and cannot fall into the creep area.

Step 8: Check Water and Feed Systems

Test the nipple drinker for flow rate. Clean the feed trough and fill it with fresh feed. Check that the feed is the correct lactation ration for your herd. The sow should be eating a lactation diet from the day she enters the farrowing crate.

Step 9: Bring the Sow In

Move the sow into the crate gently. Use a sorting panel to guide her, never a prod. Once she is in the crate, close the rear gate and observe her for a few minutes. She should settle down within 30 minutes. If she is agitated, check that the crate is not too narrow and that she has no obvious source of discomfort.

Step 10: Monitor and Adjust

Check the sow twice daily during the first 48 hours. Look for signs of discomfort: excessive standing, repeated attempts to turn around, rubbing against the bars, or vocalization. If you see these signs, adjust the crate width or check for other problems such as a sharp edge or a misaligned floor panel.

Common Mistakes in Farrowing Crate Setup

Even experienced producers make mistakes when setting up farrowing crates. Here are the most common problems and how to avoid them.

Mistake 1: Setting the Crate Too Wide

Producers often err on the side of too much room, thinking it is more comfortable for the sow. This backfires. A crate that is too wide allows the sow to turn around, which is dangerous for piglets and stressful for the sow. She may also lie diagonally, which blocks the creep area and increases crushing risk.

Fix: Set the width to the sow's hip width plus 2 to 4 inches (5 to 10 cm). Do not exceed 4 inches of extra width unless you have a specific reason.

Mistake 2: Setting the Crate Too Narrow

The opposite problem is more common with gilts. Producers use the same crate for a 400-pound gilt and a 600-pound sow without adjusting the width. The gilt has some extra room, but the sow is cramped.

Fix: Adjust the crate for each sow. If you cannot adjust, size the crate to the largest sow in the group and accept that gilts will have extra room. Better yet, sort sows by size and use different crates for different groups.

Mistake 3: Ignoring Flooring Problems

A crate with perfect dimensions sits on a floor that is slippery, uneven, or has sharp edges. The sow slips when she lies down, which causes her to flop and increases crushing risk. Sharp edges on slats or mats cause shoulder and hoof injuries.

Fix: Inspect the floor before each farrowing group. Replace damaged slats, grind down sharp edges, and clean mats thoroughly. A textured surface is essential for traction.

Mistake 4: Poor Creep Area Design

Some producers make the creep area too small or position the heat source incorrectly. Piglets cannot all fit in the creep area, so some lie next to the sow and get crushed. Or the heat source is too weak, so piglets pile up against the sow for warmth.

Fix: Make the creep area at least 8 inches (20 cm) wide on each side. Use a heat lamp rated for the size of the area and position it so the warm zone covers the entire lying area. Check the temperature with a thermometer, not your hand.

Mistake 5: Forgetting the Rear Gate

The rear gate is a safety feature and a management tool. Some producers leave the rear gate open or remove it to make cleaning easier. This allows the sow to back out or piglets to escape into the aisle.

Fix: Always close and latch the rear gate. Use the rear gate to guide piglets back into the crate during processing. If you need better access for cleaning, use a crate with a removable rear gate that locks securely.

Mistake 6: Not Adjusting for Parity

A first-parity gilt is not a small version of a mature sow. She has a different body shape, different behavior, and different nutritional needs. Using the same crate settings for all sows ignores these differences.

Fix: Group gilts together in the farrowing room and use narrower crate settings for them. This also makes it easier to give gilts extra attention during farrowing and early lactation.

Mistake 7: Neglecting Maintenance

Farrowing crates take abuse. Sows rub against the bars, manure corrodes the metal, and pressure washers wear down coatings. A crate that was safe when installed may have sharp edges or weakened welds after five years of use.

Fix: Inspect crates between farrowing groups. Look for rust, sharp edges, loose bolts, and worn coatings. Repair or replace damaged parts immediately. Keep a maintenance log for each crate.

Decision Thresholds for Crate Replacement

Farrowing crates are a long-term investment, but they do not last forever. Use these thresholds to decide when to repair or replace.

Structural Integrity

Inspect the crate for rust, especially at weld points and where the frame meets the floor. Surface rust can be cleaned and painted, but rust that has eaten through the metal is a structural failure. If you can push a screwdriver through any part of the frame, replace the crate.

Check the adjustment mechanism on adjustable crates. If the ratcheting mechanism no longer holds its position or the pins will not seat, the crate is unsafe. Replace the mechanism or the entire crate.

Sow Fit

Track how many sows in your herd exceed 90 percent of the crate width. If your standard crates are 24 inches (61 cm) wide and your sows now measure 22 inches (56 cm) across the hips, they have only 2 inches of extra room. This is the minimum acceptable clearance. If your sows consistently measure above 90 percent of the crate width, you need wider crates.

Injury Rates

Keep records of shoulder sores, hip injuries, and lameness in the farrowing room. If more than 5 percent of sows develop shoulder sores that do not heal before weaning, your crate design is contributing to the problem. This is a signal to add mats, widen the crate, or replace worn equipment.

Crushing Losses

Preweaning mortality from crushing should be below 8 percent of piglets born alive. If crushing losses exceed 10 percent and you have ruled out sow health problems, the crate design is likely a factor. Check the width, the bar spacing, and the creep area before replacing equipment.

Age of Equipment

Well-maintained steel crates last 10 to 15 years. Plastic-coated crates last 8 to 12 years before the coating wears through. If your crates are older than this and showing signs of wear, replacement is more cost-effective than continued repair.

Monitoring Sow Comfort and Performance

You cannot manage what you do not measure. Set up a simple monitoring system to track sow comfort and crate performance.

Daily Observations

Walk the farrowing room twice daily and record the following for each sow:

Posture: Is she lying on her side, lying on her chest, or standing? A sow that spends more than 20 percent of the day standing may be uncomfortable.
Behavior: Is she eating normally? Is she aggressive when you approach? Is she grinding her teeth or chewing on the bars?
Skin condition: Check her shoulders, hips, and rear for redness, hair loss, or open sores.
Milk letdown: Does she allow piglets to nurse without getting up? Sows that consistently stand during nursing may be in pain.

Weekly Records

Once a week, weigh or body condition score each sow. A sow that loses more than 1.5 body condition points during lactation is losing too much weight. This affects her next litter and her long-term health.

Track feed intake per sow per day. A lactating sow should eat 10 to 14 pounds (4.5 to 6.4 kg) per day. If intake drops below 8 pounds (3.6 kg), investigate the cause. It may be the crate, the temperature, or a health problem.

Litter Performance

Weigh piglets at birth and at weaning. Average daily gain should be 0.4 to 0.6 pounds (0.18 to 0.27 kg) per day. If gains are below this range, the sow may not be milking well, which can be a comfort issue or a nutrition issue.

Recordkeeping System

Use a simple spreadsheet or a paper log. For each crate, record:

Crate number and width setting
Sow ID, parity, and entry date
Farrowing date and number of piglets born alive
Number of piglets weaned and preweaning mortality
Sow body condition score at entry and at weaning
Any injuries or health problems
Feed intake per day

Review these records monthly. Look for patterns. If sows in a specific row or a specific crate type have more injuries or higher mortality, investigate that equipment.

When to Call a Veterinarian or Extension Agent

Most farrowing crate problems are management issues you can solve yourself. But some situations require professional help.

Call a Veterinarian If

Sows show signs of lameness that does not improve within 48 hours of crate adjustment
More than 10 percent of sows in a farrowing group develop shoulder sores
Preweaning mortality from crushing exceeds 15 percent despite correct crate setup
Sows refuse to eat for more than 24 hours after entering the crate
You see signs of infection at pressure points, including swelling, heat, or discharge
Piglets are being born with injuries consistent with trapping in the crate

Call an Extension Agent or Equipment Specialist If

You are designing a new farrowing room and need help with crate layout and ventilation
You are considering switching from fixed to adjustable crates and want a cost analysis
You need help developing a recordkeeping system for sow comfort metrics
You are experiencing unexplained increases in crushing losses and have ruled out health problems
You want to evaluate alternative farrowing systems such as free-access or group housing

What to Have Ready Before You Call

Write down the following information before contacting a professional:

Number of sows in the affected group and their parities
Crate type, age, and width settings
Preweaning mortality rate for the last three groups
Sow injury rates and types of injuries
Feed intake and body condition data
Any changes you have made to the crates or the farrowing room

This information helps the professional diagnose the problem faster and gives you a concrete plan to follow.

Frequently Asked Questions

What is the standard width for a farrowing crate?

The standard inside width is 22 to 26 inches (56 to 66 cm). Narrow crates around 22 inches suit gilts and smaller sows. Wide crates around 26 inches suit mature sows. The correct width for an individual sow is her hip width plus 2 to 4 inches (5 to 10 cm) of clearance.

How do I know if my farrowing crate is too narrow?

Watch the sow for signs of discomfort. She may spend more time standing, have difficulty lying down, rub against the bars, or develop skin lesions on her hips and shoulders. If she has less than 2 inches (5 cm) of clearance on each side, the crate is too narrow.

Can a farrowing crate be too wide?

Yes. If the crate is more than 4 inches (10 cm) wider than the sow's hip width, she may be able to turn around. A sow that turns in her crate is dangerous to piglets and can get stuck. She may also lie diagonally, which blocks the creep area.

How often should I adjust the crate width?

Adjust the width for each sow before she enters the crate. Do not adjust the crate with a sow inside. If you have a uniform herd, you may only need to adjust crates between groups. If you have mixed parities, adjust for each individual sow.

What is the best flooring for a farrowing crate?

Plastic-coated expanded metal is the most common and generally the best choice. It provides good traction, is easy to clean, and is more comfortable than bare metal. Concrete with a roughened surface works well but is harder to keep clean. Fully slatted floors work if the slat width and gap are correct.

How much space does a piglet need in the creep area?

Each creep area should be 8 to 12 inches (20 to 30 cm) wide and run the full length of the sow area. The lying zone should have a heat source and a solid floor or mat. The elimination zone should have slatted flooring to allow waste to fall through.

Should I use mats in my farrowing crates?

Rubber mats in the sow area reduce pressure on the shoulders and hips, especially for older sows. They are worth the cost if you have a history of shoulder sores or if your sows are heavy. Mats require regular cleaning to prevent bacteria buildup.

How long do farrowing crates last?

Well-maintained steel crates last 10 to 15 years. Plastic-coated crates last 8 to 12 years before the coating wears through. Replace crates when rust compromises structural integrity, when the adjustment mechanism fails, or when your sows consistently exceed 90 percent of the crate width.
