Calf Barn Manure Management: Gutter, Flush, and Scraper Systems

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

Key Takeaways

• Calf barn manure management systems (gutter, flush, scraper) directly impact calf health by reducing pathogen exposure from scours-causing agents (e.g., Cryptosporidium, E. coli) and minimizing ammonia buildup that weakens respiratory defenses, thereby mitigating risks of pneumonia.
• Gutter systems, suitable for smaller barns with slopes, rely on gravity and manual or mechanical (auger/chain) removal, requiring moderate labor and a consistent 1-2% slope for effective drainage to prevent pooling and bacterial growth.
• Flush systems, ideal for large barns, utilize high water volumes (50-100 gallons per flush) and a 2-4% alley slope for rapid, complete waste removal with low daily labor, but demand substantial water resources and careful climate management to prevent freezing.
• Scraper systems, effective for flat floors, employ mechanical blades to push manure to a collection point without water, but necessitate smooth concrete surfaces to prevent blade wear and require moderate to high labor for operation and maintenance of mechanical parts.
• Regardless of system choice, daily visual checks of calf health and bedding moisture, along with a written maintenance log for all equipment and a backup plan for power outages, are critical for operational success and disease prevention.

Raising healthy calves starts with a clean, dry environment. Manure management is not just about keeping the barn presentable. It directly affects calf health, labor costs, bedding use, and the safety of the people working inside the facility. This guide compares the three most common methods for moving manure out of a calf barn: gutter systems, flush systems, and scraper systems. It is written for dairy producers, calf raisers, farm managers, and agricultural students who need to choose a system, improve an existing one, or troubleshoot a failing setup. You will learn how each system works, what it costs to run, where it fails, and how to match a system to your barn layout, climate, and labor force.

At a Glance

Practical takeaways:

• Match the system to your barn's slope and floor type before you buy equipment.
• Gutter systems work best when you can maintain a consistent drop from the bed pack to the collection channel.
• Flush systems require a large holding tank and a pump sized for your alley length and width.
• Scraper systems need a flat, smooth floor. Rough concrete destroys blades and chains.
• No system replaces daily visual checks of calf health and bedding moisture.
• Keep a written maintenance log for every pump, motor, chain, and blade.
• Always have a backup plan for manure removal during power outages or equipment failure.

Understanding the Problem: Why Calf Barn Manure Management Matters

Calves are born without a fully developed immune system. They depend on passive immunity from colostrum and then on a clean environment to reduce pathogen exposure. Manure is the primary vehicle for many calfhood diseases, including scours caused by rotavirus, coronavirus, Cryptosporidium, and various strains of E. coli. When calves lie in soiled bedding or breathe air heavy with ammonia from decomposing urine, their respiratory defenses weaken. Pneumonia becomes a constant threat.

The physical layout of the barn determines which manure removal system is practical. A barn built on a slope can use gravity to move liquid. A barn on flat ground needs mechanical help. The local climate matters too. In cold regions, flush systems can create ice on floors and in alleys during winter. In dry regions, water conservation may rule out flushing altogether. Your labor situation is equally important. A scraper system requires someone to operate the tractor or winch on a schedule. A flush system requires less daily attention but needs regular maintenance on pumps and valves.

The goal of any manure management system is to remove waste from the calf living area quickly and completely, without stressing the calves or endangering workers. The system should also move manure to a storage area or treatment facility that meets local environmental regulations. A system that works in July may fail in January if it was not designed for freezing temperatures. A system that works with 20 calves may be overwhelmed when the barn expands to 100 calves.

Calf Barn Gutter Systems

A gutter system is the most traditional method for removing manure from a calf barn. It consists of a channel or trough built into the floor behind or below the calf stalls. The channel collects manure and urine, and workers remove the material on a regular schedule. The gutter can be open to the room or covered with grates. Some gutters are designed to be cleaned with a hand tool, while others use a mechanical auger or chain to move material to one end of the barn.

Design and Layout

The gutter runs along the back of the calf pens or stalls. The floor of the pen slopes slightly toward the gutter so that urine and liquid manure drain away from the calf resting area. The gutter itself slopes toward a collection point, usually at one end of the barn. This slope is critical. Without it, liquid pools in the gutter and creates a breeding ground for flies and bacteria.

A typical gutter is 12 to 18 inches wide and 8 to 12 inches deep. The exact dimensions depend on the number of calves and how often you plan to clean. A larger gutter holds more waste between cleanings but is harder to clean thoroughly. A smaller gutter requires more frequent attention but is easier to keep clean.

The gutter floor should have a minimum slope of 1 to 2 percent toward the collection point. This means a drop of 1 to 2 feet for every 100 feet of gutter length. If your barn floor is flat, you may need to build up the floor or cut a deeper channel at the end to create the necessary pitch.

Cleaning Methods

There are three common ways to remove manure from a gutter:

Manual cleaning. This is the simplest and least expensive method. A worker uses a square shovel or a specialized gutter scraper to push manure to the collection point. The material is then loaded into a spreader or storage area. Manual cleaning works well for small barns with fewer than 20 calves. The downside is labor. Cleaning a gutter by hand takes 15 to 30 minutes per day for a small barn, and the work is physically demanding.

Auger systems. An auger sits in the bottom of the gutter and rotates to move manure along the channel to a collection pit or cross auger. The auger is powered by an electric motor and can run on a timer or be started manually. Auger systems are effective for gutters up to 100 feet long. They reduce labor compared to manual cleaning but require regular maintenance. Manure can wrap around the auger flights, and straw or other bedding can jam the mechanism.

Chain and flight systems. A chain with attached flights or paddles runs through the gutter and pulls manure to the collection point. The chain is driven by a sprocket at one end and returns through a separate channel or through the same channel in the opposite direction. These systems are common in tie-stall barns and work well for gutters up to 200 feet long. They are more expensive than augers but handle straw and fibrous manure more effectively.

Step-by-Step Gutter Installation

If you are installing a new gutter system, follow these steps:

1. Determine the collection point. Choose the end of the barn where manure will exit. This should be close to your storage area or manure spreader access point.
2. Calculate the slope. Measure the length of the gutter run. Allow at least 1 foot of drop per 100 feet of length. Mark the high end and low end on the barn floor.
3. Excavate the channel. Cut the concrete or dig out the floor to the required depth. The channel should be slightly wider than your cleaning equipment.
4. Form the gutter. Use forms to create the channel walls. The walls should be smooth and straight. A rounded bottom is easier to clean than a square bottom.
5. Pour the concrete. Use a high-strength mix with a smooth finish. Trowel the surface to remove voids where manure can collect.
6. Install the cleaning mechanism. If using an auger or chain, mount the drive unit at the collection end and the idler at the far end. Follow the manufacturer's instructions for alignment and tension.
7. Test the system. Run the auger or chain with water to check for jams and to verify that material moves to the collection point.
8. Install grates or covers. If the gutter is in a walkway or where calves could step into it, install a sturdy grate that can support the weight of a person and a calf.

Common Gutter Mistakes

The most common mistake is insufficient slope. If the gutter is flat or has low spots, liquid pools and creates a foul environment. The second most common mistake is making the gutter too narrow. A narrow gutter is hard to clean and overflows quickly. The third mistake is using a cleaning mechanism that is undersized for the barn. An auger that is too small or underpowered will jam constantly. The fourth mistake is ignoring the collection point. If the manure pile at the end of the gutter blocks the flow, the entire system backs up.

Another frequent error is placing the gutter on the wrong side of the pen. Calves naturally dung and urine in a specific area, usually the corner farthest from the feed alley. Watch your calves for a few days to identify the high-traffic elimination area before pouring concrete. A gutter in the wrong location does not capture manure and becomes a nuisance.

Calf Barn Flush Systems

Flush systems use a large volume of water to wash manure down a sloped alley or gutter and into a collection channel. The water is released from a tank or a series of nozzles at the high end of the alley. The surge of water carries manure to a cross channel at the low end, which leads to a storage lagoon or separator. Flush systems are common in large dairy operations because they require very little daily labor and remove manure quickly and completely.

How a Flush System Works

A flush system has five main components:

• A water source, which can be fresh water, recycled lagoon water, or a combination
• A storage tank or reservoir at the high end of the barn
• A release valve or gate that opens to release the water
• A sloped alley or floor that directs the water and manure to a collection channel
• A collection channel and solids separator or storage facility

The flush tank is filled continuously or on a timer. When the valve opens, the full volume of water is released at once. The water surges down the alley at a depth of several inches and at a speed that carries manure, bedding, and hair to the collection point. The alley must have a consistent slope of 2 to 4 percent. A slope steeper than 4 percent may cause water to channel and miss manure. A slope less than 2 percent may leave manure behind.

Water Requirements

Flush systems use a large amount of water. A typical flush uses 50 to 100 gallons per flush for a 10-foot-wide alley that is 100 feet long. If you flush two or three times per day, that is 10,000 to 30,000 gallons per day for a single alley. Larger barns with multiple alleys can use over 100,000 gallons per day.

Most operations recycle water from a lagoon or settling basin. Fresh water is added only to replace losses from evaporation, solids removal, and seepage. Recycled water contains bacteria and nutrients, but it is acceptable for flushing because the goal is to move manure, not to sanitize the floor. However, recycled water can carry pathogens. If calves are in direct contact with the flushed floor, you must consider the disease risk. Some operations flush calf barns with fresh water and reserve recycled water for adult cow alleys.

Step-by-Step Flush System Installation

1. Assess your water source. Calculate how much water you can supply per day. Do not plan a flush system if your well or municipal supply cannot deliver the required volume.
2. Design the alley slope. The floor of the calf area must have a minimum slope of 2 percent. If your existing barn is flat, you may need to pour a new floor with a built-in slope.
3. Install the collection channel. The low end of the alley must have a channel wide enough to handle the full surge of water. A channel that is too small will overflow and flood the barn.
4. Build the flush tank. The tank should hold enough water for one complete flush. The outlet should be at the bottom of the tank or through a large gate that opens quickly. A valve that opens slowly will not create the surge you need.
5. Install the release mechanism. This can be a manual gate, a timer-controlled valve, or an automated system that flushes when the barn reaches a set temperature or when a sensor detects manure buildup.
6. Route the water to storage or treatment. The collection channel must lead to a lagoon, pit, or separator. Do not discharge flush water to a stream or ditch without checking local regulations.
7. Test the system. Run a flush with clean water to check the flow pattern. Adjust the slope or add guide walls if the water channels or leaves dry spots.

Flush System Maintenance

Flush systems require regular maintenance to operate reliably. The flush valve is the most critical component. A valve that sticks open drains the tank and floods the barn. A valve that sticks closed means no flush occurs and manure builds up. Inspect the valve weekly and clean any debris from the seat.

The alley floor must be kept free of obstructions. A bale of straw, a dropped feed bucket, or a calf that lies in the alley can block the flow and create a dam. Check the alley before each flush and remove any large objects.

The collection channel can become clogged with straw, hair, and manure solids. Inspect the channel weekly and remove any buildup. If you use a solids separator, clean the screens or augers according to the manufacturer's schedule.

Common Flush System Mistakes

The most common mistake is undersizing the water supply. A system that works for 20 calves will not work for 100 calves. The second mistake is using too little water per flush. A weak flush moves the manure only partway down the alley, leaving a smear that dries and becomes very difficult to remove. The third mistake is insufficient slope. A floor that is nearly flat will not allow water to carry manure effectively. The fourth mistake is flushing too frequently or too rarely. Flushing too often wastes water and keeps the floor constantly wet. Flushing too rarely allows manure to dry and stick to the concrete.

A serious mistake in calf barns is flushing while calves are in the pen. The surge of water is loud and can startle calves. In cold weather, the wet floor can chill calves and increase the risk of pneumonia. Some operations move calves to a separate area before flushing. Others use a solid floor that drains away from the calf resting area so the flush does not wet the bedding.

Calf Barn Scraper Systems

Scraper systems use a mechanical blade or a series of blades to push manure along an alley to a collection point. The scraper can be mounted on a skid steer or tractor, or it can be a stationary system with a cable or chain that pulls a blade back and forth across the floor. Scraper systems work well in barns with flat floors and are popular in operations that want to avoid the water use of flush systems.

Tractor-Mounted Scrapers

The simplest scraper system is a blade attached to a skid steer or tractor. The operator drives down the alley, pushing manure to a cross channel or collection pit. This method requires no permanent installation and can be adapted to any barn layout. The downsides are labor and scheduling. Someone must operate the machine on a regular schedule, often two or three times per day. In cold weather, the operator must work in the cold. In warm weather, the operator is exposed to flies and odors.

Tractor-mounted scrapers work best in barns with wide alleys that allow the machine to turn around. A dead-end alley requires the operator to back out, which is slow and difficult. If you use this method, keep the alley clear of feed bunks, waterers, and other obstructions.

Stationary Scraper Systems

A stationary scraper system has a blade that moves back and forth along a fixed path. The blade is pulled by a cable or chain that is driven by an electric motor. The system is installed in the floor or along one side of the alley. When the motor runs, the blade moves down the alley, pushing manure to a collection pit. When it reaches the end, it reverses and returns to the starting position.

Stationary scrapers can be set on a timer to run several times per day. They require very little daily labor, but they need regular maintenance. The cables stretch and need adjustment. The blades wear down and need replacement. The drive motor and gearbox need lubrication and inspection.

Step-by-Step Scraper System Setup

1. Evaluate your floor. The floor must be smooth and flat. Cracks, spalled concrete, and expansion joints can catch the blade and cause damage. Repair any damage before installing a scraper.
2. Choose the blade path. The scraper should travel the full length of the alley and deposit manure in a cross channel or pit at one end. The pit should be large enough to hold the manure between removals.
3. Install the drive unit. The motor and gearbox should be mounted at one end of the alley, protected from manure and weather. The cable or chain runs along the alley to a pulley or sprocket at the far end.
4. Mount the blade. The blade should be slightly narrower than the alley and should have a rubber or polyurethane edge that conforms to the floor. A rigid steel blade will not clean as well and will damage the floor.
5. Set the timer. Start with two or three scraper runs per day. Adjust the frequency based on how quickly manure accumulates and how clean the floor stays.
6. Test the system. Run the scraper with the alley empty to check for jams and to verify that the blade travels the full length. Watch for areas where the blade lifts off the floor.

Scraper System Maintenance

The most important maintenance task is checking the blade edge. A worn blade leaves a thin layer of manure on the floor, which dries and becomes a source of ammonia and bacteria. Replace the blade when the edge shows significant wear, usually every 3 to 6 months depending on use.

The cable or chain needs regular inspection. A stretched cable can slip off the pulley and cause the blade to stop. A broken chain can cause the blade to jam and the motor to overheat. Check the tension monthly and adjust according to the manufacturer's instructions.

The drive motor and gearbox should be serviced according to the manufacturer's schedule. Keep the motor clean and free of dust and manure. Make sure the electrical connections are protected from moisture.

Common Scraper System Mistakes

The most common mistake is installing a scraper on a rough or damaged floor. The blade catches on every crack and joint, causing constant jams and rapid blade wear. The second mistake is using a blade that is too narrow. A narrow blade leaves a strip of manure along the walls, which builds up over time. The third mistake is setting the timer incorrectly. Running the scraper too often wears out the blade and motor. Running it too rarely allows manure to accumulate and dry.

Another mistake is placing the collection pit in the wrong location. If the pit is too small, it overflows and manure spreads back onto the alley. If the pit is too deep or has steep sides, it is difficult to empty with a loader. The pit should be sized to hold at least two days of manure production and should be accessible from outside the barn for emptying.

Comparing the Systems: Decision Thresholds

Choosing the right system depends on your specific situation. Use these thresholds to guide your decision.

Choose a Gutter System If:

• You have fewer than 50 calves.
• Your barn has a natural slope or you can build one into the floor.
• You have labor available for daily cleaning.
• You want to minimize water use.
• You are on a limited budget and can do the installation yourself.

Choose a Flush System If:

• You have more than 50 calves or plan to expand.
• You have a reliable water source that can deliver 50 to 100 gallons per flush per alley.
• You want to minimize daily labor.
• You have a lagoon or storage facility for the flush water.
• Your climate is warm enough that freezing is not a major concern, or you can design the system to drain completely in winter.

Choose a Scraper System If:

• Your barn has a flat floor with smooth concrete.
• You want to avoid the water use of a flush system.
• You have a tractor or skid steer available for a mounted scraper.
• You are willing to perform regular maintenance on cables, chains, and blades.
• You have a collection pit or cross channel at one end of the alley.

Cost Considerations

Gutter systems are the least expensive to install. A simple concrete gutter with manual cleaning costs only the price of the concrete and the shovel. Adding an auger or chain increases the cost but reduces labor. For a 100-foot gutter, expect to pay $3,000 to $8,000 for an auger system installed.

Flush systems have the highest installation cost. The flush tank, valve, piping, and collection channel can cost $10,000 to $30,000 per alley, depending on the size and complexity. Operating costs include electricity for the pump and the value of the water used. If you recycle lagoon water, the water cost is lower, but you must maintain the lagoon and pump system.

Scraper systems fall in the middle. A tractor-mounted scraper blade costs $500 to $2,000. A stationary scraper system for a 100-foot alley costs $8,000 to $20,000 installed. Operating costs include electricity for the motor and replacement blades and cables.

Labor Comparison

Gutter systems require the most labor, especially if you clean manually. Plan for 15 to 30 minutes per day for a small barn. Auger and chain systems reduce this to 5 to 10 minutes per day for checking and starting the mechanism.

Flush systems require the least daily labor. Once the timer is set, the system runs automatically. Plan for 10 to 15 minutes per day to check the valve, inspect the alley, and verify that the collection channel is clear.

Scraper systems require moderate labor. A tractor-mounted scraper takes 20 to 40 minutes per cleaning, two or three times per day. A stationary scraper takes 5 to 10 minutes per day for inspection, plus periodic maintenance.

Monitoring and Recordkeeping

No manure removal system works perfectly without oversight. You must monitor the system daily and keep records of maintenance and problems. A written log helps you spot patterns and address issues before they become serious.

Daily Checks

Walk the calf barn at the same time each day. Look for:

• Manure buildup in the gutters, alleys, or collection channels.
• Wet spots in the calf bedding that indicate poor drainage.
• Flies around the manure collection area.
• Unusual odors, especially ammonia.
• Calves with soiled legs or tails.
• Signs of scour or respiratory disease in the calves.

Check the mechanical components of your system. For a gutter, verify that the auger or chain is moving and that the collection point is not blocked. For a flush system, confirm that the tank is full and the valve operates correctly. For a scraper, check that the blade travels the full length and that the cable or chain is not frayed.

Weekly Checks

Once per week, do a more thorough inspection. Check the blade edge on a scraper and the auger flights on a gutter system. Look for wear on chains, sprockets, and pulleys. Verify that the flush valve closes completely and does not leak. Check the collection pit or cross channel for solids buildup that could clog the outlet.

Recordkeeping

Keep a simple log with the date, the system component checked, and any problems found. Note the action taken to fix the problem. This log helps you track maintenance intervals and identify recurring issues. For example, if you replace the scraper blade every 3 months consistently, you can schedule the replacement before it fails.

Record the amount of water used for flushing. A sudden increase in water use may indicate a leaking valve or a stuck flush mechanism. A sudden decrease may indicate a blocked pipe or a failing pump.

Track the health of your calves. Record cases of scours, pneumonia, and other diseases. If you see a spike in disease after changing your manure removal schedule, the two may be related. Review your records monthly to identify trends.

When to Adjust the System

If you notice manure buildup in a specific area, adjust the system to address it. For a gutter, increase the frequency of cleaning or add a second cleaning pass in the problem area. For a flush system, increase the water volume or adjust the direction of the water flow. For a scraper, adjust the timer to run more frequently or repair the blade.

If calves are consistently dirty, the system is not removing manure effectively. Check that the bedding is dry and that the calf resting area is elevated above the manure collection area. If the problem persists, consider adding more bedding or redesigning the pen layout.

Common Mistakes and How to Avoid Them

Mistake 1: Ignoring the Floor Slope

Every manure removal system depends on a properly sloped floor. A gutter needs slope to drain. A flush alley needs slope to carry water. A scraper needs a flat, smooth floor to operate without jamming. Before you install any system, verify the slope and condition of your floor. Use a long level or a laser level to check the grade. Fix any low spots or rough areas before proceeding.

Mistake 2: Undersizing the Collection System

The collection point is the bottleneck of any manure removal system. If the collection pit is too small, it overflows. If the cross channel is too narrow, it clogs. Size the collection system for your peak production, not your average production. During spring and fall, when calves are larger and eat more, manure volume increases. Design for these peaks to avoid overflow.

Mistake 3: Neglecting Winter Conditions

Cold weather changes how manure removal systems perform. Flush systems can freeze if water remains in the alley or pipes. Scraper systems can have blades that stick to a frozen floor. Gutter systems can have augers that jam when manure freezes. Plan for winter by insulating pipes, draining flush systems when not in use, and using a de-icing agent on scraper blades.

Mistake 4: Forgetting About Ventilation

Manure removal is closely tied to air quality. Even a perfectly cleaned barn can have high ammonia levels if ventilation is poor. Ammonia irritates the respiratory tract and makes calves more susceptible to pneumonia. Ensure your barn has adequate ventilation to remove moisture and gases from the manure collection area. In winter, you may need to balance ventilation with heat retention.

Mistake 5: Skipping Safety Training

Manure removal systems involve moving machinery, electricity, and large volumes of water. Workers who operate these systems need training on safe procedures. Never allow anyone to put a hand or foot near a moving auger or chain. Lock out electrical power before servicing any motor. Post warning signs near flush valves and collection pits.

When to Call a Veterinarian or Extension Agent

Most manure management problems are mechanical and can be solved with adjustments or repairs. However, some situations require professional help.

Call a Veterinarian If:

• You see a sudden increase in calf scours or pneumonia cases.
• Multiple calves show signs of dehydration or weight loss.
• Calves are consistently dirty and you cannot identify the cause.
• You suspect that the manure removal system is contributing to disease spread.

A veterinarian can help you determine if the manure handling system is a disease risk. They can test water sources, evaluate bedding moisture, and recommend changes to your cleaning schedule.

Call an Extension Agent If:

• You are planning a new barn or major renovation.
• You need help calculating water requirements for a flush system.
• You are unsure about local environmental regulations for manure storage.
• You want to compare the costs of different systems for your specific operation.

Extension agents have access to research-based information and can provide objective advice. They can also connect you with other producers who have installed similar systems and can share their experiences.

Frequently Asked Questions

How often should I clean the calf barn gutter?

Clean the gutter at least once per day. In warm weather, when flies are active and manure decomposes faster, clean twice per day. The goal is to remove manure before it attracts flies or generates ammonia. If you use an auger or chain system, run it once in the morning and once in the evening. If you clean manually, schedule the cleaning at the same time each day so it becomes a routine.

Can I use recycled lagoon water for flushing a calf barn?

Yes, but with caution. Recycled water contains bacteria from adult cow manure, which can include pathogens that affect calves. If you use recycled water, flush the alley when calves are not present and allow the floor to dry completely before calves return. Some operations use recycled water for the main flush and follow with a fresh water rinse to reduce pathogen load. Discuss the disease risks with your veterinarian before using recycled water in a calf facility.

What is the minimum slope for a flush alley?

The minimum slope is 2 percent, which is a drop of 2 feet per 100 feet of length. A slope of 3 to 4 percent works better and reduces the amount of water needed per flush. Slopes steeper than 5 percent can cause water to channel and miss manure, so avoid excessive slope.

How much water does a flush system use per day?

A typical flush uses 50 to 100 gallons per flush for a 10-foot-wide alley that is 100 feet long. If you flush three times per day, that is 150 to 300 gallons per day for that alley. Larger barns with multiple alleys use much more. Most operations recycle water to reduce fresh water use. Calculate your daily water requirement before installing a flush system to ensure your water source can meet the demand.

My scraper blade leaves a thin layer of manure on the floor. What should I do?

A thin layer of manure usually means the blade edge is worn or the blade is not making full contact with the floor. Check the blade edge for wear and replace it if needed. Verify that the blade is properly adjusted and that the mounting hardware is tight. If the floor is rough or has low spots, the blade may not contact the surface evenly. Repair the floor or add a flexible edge to the blade that conforms to the surface.

Can I install a flush system in an existing barn with a flat floor?

Yes, but you will need to create a slope. This may involve pouring a new concrete floor with a built-in slope, which is a major renovation. An alternative is to use a scraper system, which works on a flat floor. If you are set on a flush system, consult with a concrete contractor who has experience with dairy barn floors.

How do I prevent the flush system from freezing in winter?

Completely drain the flush tank, pipes, and valves after each use. Insulate the tank and pipes if they are exposed to cold air. Some operations use a heated valve or a small heater in the tank to prevent freezing. If the alley freezes, the flush water can turn to ice and create a hazard for calves and workers. Consider switching to a scraper system during the coldest months if freezing is a persistent problem.

What is the best way to handle manure from a calf barn during a power outage?

Keep a backup plan ready. For a gutter system, you can clean manually with a shovel. For a scraper system, you can use a tractor-mounted blade if you have one. For a flush system, you may need to use a portable pump or gravity drain to move water and manure. Have a generator available to power critical equipment. Plan for at least 24 hours without power and make sure you can remove manure and provide fresh water to calves during that time.
