Feedlot Winterization and Cold Weather Preparation

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

Key Takeaways

Cold stress significantly impacts cattle performance, reducing average daily gain by 10-30% and decreasing feed efficiency by diverting energy from growth to thermoregulation. Factors like wind, moisture, and mud can elevate the lower critical temperature from 18-20°F to as high as 40°F.
Windbreaks are critical for mitigating cold stress; a single windbreak can reduce wind speed by 50-75%, dramatically lowering the energy cattle expend to stay warm. Natural windbreaks (conifers) and artificial porous barriers (50-60% porosity) are most effective when placed strategically upwind of resting and feeding areas.
Nutritional requirements increase in cold weather, necessitating a 10-25% increase in dietary energy, often achieved by increasing high-energy grains or adding fat supplements. Warm water (40-65°F) is crucial for maintaining feed intake and digestion, as cold water can reduce consumption.
Dry bedding, with a minimum of 6-12 inches of straw, corn stalks, or wood shavings, is paramount for insulation and disease prevention. Mud destroys the insulating properties of a cattle's coat, increasing heat loss and the risk of foot rot and lameness.
Proactive health management is vital, with respiratory disease incidence spiking due to cold air irritation and increased pathogen transmission in crowded shelters. Prompt veterinary attention is required for signs of severe respiratory distress, frostbite, hypothermia, or lameness.
A comprehensive winter emergency plan addressing power outages, water system failures, blizzards, and equipment breakdowns is essential. This includes having backup generators, alternative water sources, adequate feed/bedding reserves, and clear communication protocols with staff and veterinarians.

Winter presents one of the most demanding seasons for feedlot operators. Cold temperatures, snow, ice, and wind challenge cattle health, weight gain, and operational efficiency. Proper feedlot winter preparation reduces stress on animals, prevents costly health problems, and keeps your operation running smoothly when temperatures drop. This guide covers the essential steps for winterizing your feedlot, from facility assessment and windbreak installation to feeding adjustments and emergency planning. It is written for feedlot owners, managers, and farm staff who want practical, actionable strategies for cold weather management.

At a Glance

Assess facilities early: Inspect pens, fences, and water systems before the first hard freeze.
Install or repair windbreaks: Wind protection reduces cold stress more than any other structural change.
Adjust rations for cold: Increase energy intake by 10 to 25 percent during severe cold events.
Ensure water never freezes: Cattle drink more in winter when water is warm and accessible.
Plan snow removal routes: Keep feed alleys, gates, and handling facilities accessible.
Provide dry bedding: Mud and moisture increase heat loss and disease risk.
Monitor body condition weekly: Identify thin cattle early and adjust management.
Have an emergency plan: Power outages, blizzards, and equipment failures require a written response plan.
Call a veterinarian for health concerns: Respiratory disease and frostbite need prompt professional attention.

Why Feedlot Winter Preparation Matters

Cold weather affects cattle performance and health in ways that go beyond simple discomfort. Cattle are homeothermic animals, meaning they maintain a constant internal body temperature. When environmental temperatures drop below their lower critical temperature, they must burn energy to stay warm. For cattle with a dry, winter coat, the lower critical temperature is around 18 to 20 degrees Fahrenheit. However, wind, moisture, and mud can raise this threshold dramatically. A wet, muddy cow in a 20 degree wind may experience cold stress at temperatures as high as 40 degrees Fahrenheit.

The economic impact of cold stress is significant. Energy diverted to maintaining body heat is energy not used for weight gain. Research from northern plains feedlots shows that cattle experiencing prolonged cold stress can reduce average daily gain by 10 to 30 percent compared to cattle in comfortable conditions. Feed efficiency also declines because cattle consume more feed but convert it less efficiently when they are cold stressed.

Health risks also increase in winter. Respiratory disease, particularly bovine respiratory disease complex, spikes during cold weather. Cold air irritates the respiratory tract, and cattle huddled together in shelters or sheds increase pathogen transmission. Frostbite can affect ears, tails, and teats, particularly in newborn calves and young stock. Mud and ice create slipping hazards that lead to injuries, lameness, and reduced feed intake. Hypothermia is a real risk for young calves and for cattle that become wet and cannot dry off.

Beyond animal welfare and performance, winterization protects your infrastructure. Frozen water lines, broken pumps, and ice-damaged fences cost money and time to repair. A proactive approach to winter preparation prevents these failures before they happen.

Assessing Your Feedlot Before Winter Arrives

Start your winter preparation with a thorough facility assessment. Walk every pen, alley, and building with a checklist. Look for problems that will become worse once snow and ice arrive. August and September are ideal months for this assessment because you have time to make repairs before the first hard freeze.

Pen and Fence Inspection

Walk the perimeter of every pen. Check for broken posts, sagging wire, and gaps that allow cattle to escape. Snow can hide fence problems, and cattle pushed by wind may test fences they normally ignore. Repair or replace damaged sections now. Pay special attention to gate latches and hinges. Frozen latches are a common winter frustration, and a gate that will not open can delay feeding or veterinary care.

Check for low spots in pens where water collects. These areas become mud holes and ice patches in winter. Grade pens to improve drainage, and consider adding gravel or limestone to high-traffic areas around bunks and waterers. Rock pads provide a drier surface and reduce mud buildup.

Water System Inspection

Water is the most critical nutrient for cattle, and winter water delivery is a common point of failure. Inspect all water lines for leaks, cracks, and inadequate insulation. Exposed pipes need heat tape or insulation. Check water heaters and tank heaters to ensure they function properly. Clean water tanks and remove sediment before winter.

Consider the location of your water sources. Waterers placed in open, windy areas are more likely to freeze. If possible, position waterers on the south side of buildings or windbreaks. Insulated, heated waterers are a worthwhile investment for northern feedlots. They cost more upfront but save labor and prevent dehydration.

Test your water system under cold conditions before you need it. Run water through the lines and verify that heaters keep water above freezing. A dry run in October can reveal problems you can fix before a November cold snap.

Building and Shelter Inspection

If you have barns, sheds, or three-sided shelters, inspect their condition. Check roofs for leaks and structural damage. Snow loads can collapse weak roofs, so repair any sagging or damaged areas. Inspect siding and roofing for gaps that create drafts. While some ventilation is necessary, direct drafts on resting cattle are harmful.

Clean out buildings before winter. Remove accumulated manure, old bedding, and debris. A clean, dry surface provides better insulation and reduces disease pressure. Stockpile bedding materials such as straw, corn stalks, or wood shavings where they will stay dry and accessible even in deep snow.

Handling Facility Readiness

Your working chute, head gate, and handling pens see heavy use in winter for processing, treatment, and pregnancy checks. Test all equipment now. Lubricate moving parts, replace worn cables, and ensure hydraulic systems are full and functioning. Cold weather makes equipment brittle and more prone to failure. A broken chute in January with a sick animal waiting for treatment is a serious problem.

Consider adding lighting to handling facilities. Winter days are short, and you may work cattle in low light conditions. Good lighting improves safety for both cattle and handlers.

Windbreaks and Shelter for Cattle

Wind is the single greatest contributor to cold stress in cattle. A 20 mile per hour wind increases the effective cold by 20 to 30 degrees Fahrenheit. A windbreak can reduce wind speed by 50 to 75 percent over a distance of 10 to 20 times the windbreak height. This reduction dramatically lowers the energy cattle need to stay warm.

Natural Windbreaks

Trees and shrubs provide excellent wind protection. A row of dense conifers such as spruce, pine, or cedar offers year-round protection. Deciduous trees provide less winter protection because they lose their leaves, but they still slow wind somewhat. Plant windbreaks on the prevailing winter wind side of your feedlot, typically the north and northwest sides.

If you have existing tree windbreaks, maintain them. Remove dead or diseased trees. Thin overly dense stands to allow some air movement, which prevents snow from drifting excessively. A solid windbreak with no gaps is more effective than several scattered rows.

Artificial Windbreaks

Where natural windbreaks are not available or established, artificial windbreaks are effective. Solid board fences, metal panels, and snow fence can all reduce wind speed. The most effective artificial windbreaks are 50 to 60 percent porous, meaning they allow some wind to pass through. Solid barriers create turbulence on the leeward side and may cause snow to drift heavily.

A common design uses horizontal wooden slats with gaps between them, or a combination of solid panels and snow fence. Install windbreaks perpendicular to prevailing winter winds. Position them 50 to 100 feet upwind of feeding areas and resting sites. A single windbreak can protect a substantial area, but multiple windbreaks placed strategically throughout the feedlot provide better overall protection.

Three-Sided Shelters

Three-sided sheds with the open side facing south or east provide excellent protection from north winds. These structures allow cattle to escape wind and precipitation while still having access to fresh air. The open side should face away from prevailing winter winds. Orient the shed so the opening faces south or southeast to capture winter sun.

Bedding is essential in shelters. Provide deep straw or other bedding to create a dry, insulated resting surface. Cattle lying on dry bedding lose far less body heat than cattle lying on cold, wet ground. Add fresh bedding regularly throughout winter, not just at the start of the season.

Snow Fence Management

Snow fence is a temporary or semi-permanent windbreak that also controls snow drifting. Properly placed snow fence can keep snow out of pens, feed alleys, and handling areas. Install snow fence upwind of areas you want to protect. The fence causes snow to drop on the downwind side, creating a drift that extends about 10 times the fence height.

Position snow fence carefully. A fence placed too close to a feed alley or gate will create a drift in the wrong place. Plan your snow fence layout in late summer or early fall before the ground freezes.

Feeding Strategies for Cold Weather

Cattle nutritional needs change dramatically in winter. As temperatures drop, cattle require more energy to maintain body condition and continue gaining weight. Understanding these changes and adjusting your feeding program is essential for winter performance.

Understanding Lower Critical Temperature

The lower critical temperature is the temperature below which cattle must expend extra energy to stay warm. For cattle with a dry, heavy winter coat, this is approximately 18 to 20 degrees Fahrenheit. However, several factors raise this threshold:

Wet or matted hair raises the lower critical temperature to near 40 degrees Fahrenheit.
Mud on the hair coat reduces insulation and increases heat loss.
Wind increases heat loss and raises the effective cold.
Thin body condition provides less insulation and energy reserve.
Young calves and older cattle are more sensitive to cold.

When the effective temperature, accounting for wind and moisture, drops below the lower critical temperature, feed intake increases automatically. Cattle eat more to fuel their increased energy needs. However, the energy density of the ration must also increase to support both maintenance and growth.

Adjusting Ration Energy

For every degree Fahrenheit below the lower critical temperature, cattle require roughly 1 to 2 percent more energy. During severe cold events with wind and moisture, energy needs can increase 20 to 40 percent above normal maintenance requirements.

Practical adjustments include:

Increase the proportion of corn or other high-energy grains in the ration.
Add fat or oil supplements to boost energy density without increasing feed volume.
Feed more forage to increase heat production through fermentation, but balance this against the need for concentrated energy.
Increase feeding frequency during extreme cold to keep feed fresh and encourage intake.

Work with a nutritionist to formulate a winter ration that matches your feed inventory and cattle class. The winter ration is not simply the summer ration fed in larger amounts. The balance of energy, protein, minerals, and fiber changes with cold stress.

Feed Delivery in Cold Weather

Cold weather affects how you deliver feed. Frozen feed, snow-covered bunks, and icy roads all complicate feeding. Plan your feeding schedule to minimize these problems.

Feed in the afternoon or evening during extreme cold. Cattle digest feed overnight, and the heat generated by digestion helps them stay warm.
Clean bunks regularly. Frozen, spoiled feed reduces intake and can cause digestive upset.
Break up frozen feed before delivery. Large frozen chunks are difficult for cattle to eat and can cause choking.
Use feeders that protect feed from snow and wind. Bunk covers or feeders with roofs reduce feed waste.
Consider feeding a total mixed ration to ensure consistent nutrient intake.

Monitor feed intake closely. A drop in intake during cold weather is a warning sign. Cattle that stop eating are at risk of hypothermia and disease. Investigate any significant intake reduction immediately.

Water Intake and Temperature

Water intake directly affects feed intake. Cattle that do not drink enough water eat less and gain less. In winter, cattle may reduce water intake if water is too cold or if they must break ice to drink.

Research shows that cattle prefer water in the 40 to 65 degree Fahrenheit range. Warm water increases intake, which supports higher feed intake and better digestion. Heated waterers that maintain water above freezing are valuable investments.

Provide at least one waterer or tank for every 50 to 75 cattle. Space water sources throughout the feedlot so cattle do not have to walk long distances in cold weather. Check water flow rates regularly. A partially frozen line or a dirty tank can reduce water availability without being obvious.

Bedding and Mud Management

Dry bedding is one of the most important winter management tools. Bedding provides insulation, keeps cattle clean and dry, and reduces disease pressure. Mud, on the other hand, is a major cause of cold stress and reduced performance.

Bedding Materials

Several materials work well for cattle bedding:

Straw is the gold standard. Wheat straw and barley straw provide excellent insulation and absorb moisture well.
Corn stalks are a good option where available. They provide reasonable insulation but break down faster than straw.
Wood shavings and sawdust work well, especially in wet conditions. They absorb moisture and provide a dry surface.
Hay that is too low quality for feeding can serve as bedding, though it breaks down quickly.

Apply bedding generously in areas where cattle lie down. A minimum of 6 to 12 inches of fresh bedding is recommended for winter. Add more bedding as the original layer becomes wet or packed. The goal is to keep cattle dry and clean at all times.

Managing Mud

Mud is more than a nuisance. Mud on a cattle coat destroys its insulating properties. A mud-caked coat that is wet against the skin can cause heat loss three to five times greater than a clean, dry coat. Mud also increases the risk of foot rot, lameness, and mastitis in cows.

Prevent mud before it forms. Grade pens to drain water away from high-traffic areas. Install rock pads around bunks, waterers, and gates. These pads provide a firm, dry surface that resists mud formation.

If mud develops despite your efforts, address it promptly. Add bedding to create a dry path through muddy areas. Consider moving cattle to drier pens if mud becomes severe. Rotating cattle between pens allows muddy pens to dry and recover.

Snow Removal from Pens

Snow removal in pens is a balance between leaving snow as insulation and removing it to keep pens usable. A light snow cover can provide some insulation and is generally not a problem. Deep snow, however, makes walking difficult, buries feed, and creates drifts that block access.

Priority areas for snow removal:

Feed alleys and bunk lines
Waterers and water tanks
Gates and handling facilities
Entry roads and driveways
Areas around windbreaks and shelters

Use a tractor with a blade or snow blower to clear these areas promptly after each snowfall. Waiting for snow to melt is not a viable strategy in most northern feedlots. A single large snowfall can shut down operations if you are not prepared.

Develop a snow removal plan before winter. Know which equipment you will use, who will operate it, and which areas get cleared first. Keep fuel and spare parts on hand for snow removal equipment.

Health Management in Cold Weather

Winter creates specific health challenges for feedlot cattle. Understanding these risks and monitoring cattle closely reduces disease and death loss.

Respiratory Disease

Bovine respiratory disease is the leading cause of illness and death in feedlot cattle, and winter conditions increase the risk. Cold air damages the respiratory lining, making cattle more susceptible to viral and bacterial infection. Stress from cold, shipping, and handling suppresses the immune system.

Prevention strategies include:

Vaccinate cattle before winter according to your veterinarian's protocol.
Avoid handling cattle during extreme cold events when possible.
Provide adequate ventilation in shelters without creating drafts.
Reduce stocking density to minimize stress and pathogen spread.
Monitor cattle daily for coughing, nasal discharge, depression, and reduced feed intake.

Early detection is critical. Cattle with respiratory disease eat less and lag behind the group. Identify sick cattle quickly and treat them according to your veterinary protocol.

Frostbite

Frostbite affects ears, tails, teats, and scrotums in extreme cold. Young calves and thin cattle are most at risk. Frostbitten tissue appears pale or white initially, then becomes red and swollen as it thaws. Severe frostbite can cause tissue death and permanent damage.

Prevention focuses on keeping cattle dry and sheltered. Provide windbreaks and bedding. Ensure newborn calves are dried quickly and placed in a warm environment. Check ears and tails during extreme cold events.

If you suspect frostbite, do not rub or massage the affected area. Warm the tissue gradually with warm water, not hot water. Contact your veterinarian for guidance.

Hypothermia

Hypothermia occurs when a cow's body temperature drops below normal. It is most common in newborn calves, thin cattle, and cattle that become wet in cold weather. Signs include shivering, lethargy, weakness, and a low body temperature.

Treatment involves warming the animal gradually. Move it to a warm, dry area. Provide warm fluids if the animal can swallow. Contact your veterinarian immediately. Severe hypothermia requires professional treatment.

Lameness and Injuries

Ice and frozen ground increase the risk of slips, falls, and leg injuries. Cattle moving through icy gates or across frozen waterers can injure themselves. Lameness reduces feed intake and can lead to secondary infections.

Prevent ice in high-traffic areas. Spread sand, gravel, or wood ash on icy patches. Keep gates and alleys clear of ice. Inspect cattle regularly for lameness and treat injuries promptly.

Foot Rot

Foot rot is more common in wet, muddy conditions, which winter often creates around waterers and bunks. The bacteria that cause foot rot thrive in mud and manure. Cattle standing in wet conditions for long periods are at higher risk.

Prevention includes keeping cattle dry, providing clean bedding, and maintaining dry areas around water sources. Treat foot rot early with antibiotics according to your veterinarian's protocol. Prompt treatment prevents complications and reduces recovery time.

Monitoring and Recordkeeping

Winter requires vigilant monitoring. Small problems that go unnoticed can become serious quickly in cold weather. Establish a daily monitoring routine and keep records that help you track performance and identify trends.

Daily Observations

Walk the feedlot at least once daily, ideally twice. Look for:

Cattle behavior: Are cattle eating, resting, and moving normally?
Feed intake: Is feed disappearing at the expected rate?
Water availability: Are waterers working and ice-free?
Cattle condition: Are any cattle thin, lame, or showing signs of illness?
Facility condition: Are fences, gates, and shelters intact?
Bedding condition: Is bedding dry, or is it wet and packed?

Use the same route each day so you cover all areas consistently. Note anything unusual in a notebook or digital record.

Body Condition Scoring

Body condition scoring is a systematic way to assess whether cattle are maintaining adequate fat reserves. The scale runs from 1 to 9, with 1 being emaciated and 9 being obese. Most feedlot cattle should maintain a score of 4 to 6 depending on stage of production.

Score cattle at the start of winter and then monthly throughout the season. Cattle losing condition need increased energy in the ration. Cattle gaining excessive condition may need a lower-energy ration. Adjust feeding accordingly.

Weather Tracking

Keep a daily log of temperature, wind speed, precipitation, and snow depth. This information helps you understand how weather affects cattle performance. It also helps you anticipate problems. If a severe cold front is forecast, you can adjust feeding and bedding before the storm arrives.

Several weather apps and websites provide forecasts specific to your location. Use these to plan daily operations. Pay attention to wind chill forecasts, which account for the combined effect of temperature and wind.

Feed Records

Track feed delivery and intake daily. Record what you feed, how much, and what the cattle consume. This information is essential for adjusting rations as weather changes. It also helps you identify problems early. A sudden drop in intake often signals illness or a feed quality issue.

Health Records

Maintain individual health records for every animal treated. Record the date, symptoms, treatment, and outcome. These records help you track disease patterns and evaluate treatment effectiveness. They also provide valuable information for your veterinarian.

Common Mistakes in Feedlot Winter Preparation

Even experienced operators make mistakes in winter preparation. Recognizing common errors helps you avoid them.

Waiting Too Long to Prepare

Many operators wait until the first snowstorm to begin winter preparation. This is too late. Repairs that are simple in September become difficult and dangerous in January. Start your winter preparation in late summer and complete it before the first hard freeze.

Ignoring Wind Protection

Wind is the biggest factor in cold stress, yet many feedlots have inadequate wind protection. A feedlot with no windbreaks will see significantly poorer cattle performance than one with good wind protection. Investing in windbreaks is one of the most cost-effective winter improvements you can make.

Feeding the Same Ration Year-Round

Cattle nutritional needs change dramatically with weather. Feeding a summer ration in January leaves cattle short on energy. Work with a nutritionist to adjust rations for winter conditions.

Letting Water Freeze

Frozen water is a critical failure. Cattle that cannot drink will stop eating and quickly become dehydrated. Check waterers multiple times daily during cold weather. Have backup plans for water delivery if your primary system fails.

Underestimating Bedding Needs

Many operators do not use enough bedding. A thin layer of bedding that becomes wet and packed provides little insulation and may actually increase cold stress. Use generous amounts of bedding and add more regularly.

Overcrowding Shelters

Cattle crowded into shelters create heat and humidity, which can increase respiratory disease. Provide adequate space per animal and ensure ventilation. A shelter that is too crowded is worse than no shelter at all.

Failing to Have an Emergency Plan

Winter emergencies happen. Power outages, blizzards, equipment breakdowns, and water system failures all require a rapid response. Operators without a written emergency plan waste time and make poor decisions under pressure.

Developing a Winter Emergency Plan

Every feedlot needs a written emergency plan for winter. This plan should cover the most likely emergencies and define specific actions for each one.

Power Outages

Power outages affect waterers, heaters, lighting, and ventilation. Have a backup generator that can power critical systems. Test the generator monthly and keep fuel on hand. Know how to manually operate water systems if the generator fails.

Water System Failure

If your primary water system fails, you need a backup. Options include:

A second water source such as a tank filled from a hydrant or hauled water.
Portable water tanks that can be filled and moved to pens.
A generator-powered pump that can draw from a pond or well.

Identify backup water sources before you need them. Practice setting up backup systems so you can do it quickly in an emergency.

Blizzard Conditions

Blizzards can shut down roads and make it impossible to reach the feedlot. If you have employees, establish a communication plan. Designate someone to check on cattle if the primary operator cannot get there.

Keep a supply of feed, bedding, and fuel on hand for at least three to five days of severe weather. A snowstorm that lasts a week should not catch you unprepared.

Equipment Failure

Tractors, feed trucks, and snow removal equipment can fail in cold weather. Keep spare parts and maintain equipment before winter. Have a plan for renting or borrowing equipment if your primary equipment fails.

Animal Health Emergency

Severe weather can trigger health emergencies such as hypothermia outbreaks or respiratory disease spikes. Your emergency plan should include contact information for your veterinarian and a clear protocol for calling them. Know which animals are at highest risk and check them first during extreme weather.

When to Call a Veterinarian

Some health problems require professional veterinary care. Do not delay calling your veterinarian when you see serious signs. Early intervention saves lives and reduces treatment costs.

Call a veterinarian immediately if you observe:

Multiple cattle with severe respiratory signs including labored breathing, deep coughing, or nasal discharge.
Cattle unable to stand or walk.
Signs of severe hypothermia such as lethargy, weakness, or unresponsiveness.
Frostbite affecting large areas of tissue.
Calving difficulties in cold weather.
Unusual deaths or a pattern of illness that does not respond to treatment.
Any animal in severe pain or distress.

Your veterinarian can also help with preventive care. Schedule a pre-winter herd health check to review vaccination protocols, parasite control, and nutrition. A veterinarian who knows your operation and your cattle is an invaluable resource during winter emergencies.

When to Call an Extension Agent

Extension agents provide educational support and can help you improve management practices. Contact your local extension office for:

Information on winter feeding strategies and ration formulation.
Guidance on windbreak design and installation.
Recommendations for bedding management and mud control.
Workshops and publications on cold weather cattle management.
Help interpreting weather data and planning for severe events.

Extension agents can also connect you with other specialists such as agricultural engineers, economists, and nutritionists. They are a free resource that many operators underuse.

Economic Considerations for Winter Management

Winter management decisions have direct economic consequences. Understanding the costs and benefits of different practices helps you allocate resources effectively.

Cost of Cold Stress

The economic cost of cold stress includes reduced weight gain, poorer feed efficiency, increased health problems, and higher death loss. A 10 percent reduction in average daily gain over a 120 day winter feeding period can reduce final weight by 30 to 50 pounds per animal. At current cattle prices, this can represent a significant loss per head.

Cost of Prevention

Prevention costs money too. Windbreaks, heated waterers, bedding, and extra feed all have costs. However, these costs are typically small compared to the losses from cold stress. A windbreak that costs several thousand dollars can save many times that amount in improved cattle performance over its lifetime.

Return on Investment

Evaluate winter improvements as investments. Calculate the expected benefit in reduced losses and improved performance, then compare this to the cost. Many winter improvements pay for themselves in one or two winters.

Prioritize improvements that address your biggest weaknesses. If wind is your main problem, invest in windbreaks first. If mud is the issue, focus on drainage and rock pads. If water freezing is a recurring problem, invest in better water systems.

Frequently Asked Questions

How much extra feed do cattle need in cold weather?

Cattle need roughly 1 to 2 percent more energy for every degree Fahrenheit below their lower critical temperature. During severe cold events with wind and moisture, energy needs can increase 20 to 40 percent above normal. Work with a nutritionist to adjust your ration formulation and feeding amounts during cold spells.

What is the best windbreak for a feedlot?

A porous windbreak that blocks 50 to 60 percent of the wind is most effective. Natural tree windbreaks, particularly dense conifers, work well. Artificial windbreaks made of wooden slats with gaps, or a combination of solid panels and snow fence, are also effective. Place windbreaks perpendicular to prevailing winter winds, 50 to 100 feet upwind of feeding and resting areas.

How often should I check waterers in winter?

Check waterers at least twice daily in winter, and more often during extreme cold events. A waterer can freeze or malfunction quickly, and cattle can become dehydrated within hours. Consider installing low-temperature alarms on critical water systems so you know immediately when a heater fails.

What is the best bedding material for cattle in winter?

Straw is the gold standard for cattle bedding because it provides excellent insulation and absorbs moisture well. Corn stalks, wood shavings, and low-quality hay also work. Apply a minimum of 6 to 12 inches of fresh bedding and add more as the original layer becomes wet or packed.

How do I know if my cattle are cold stressed?

Signs of cold stress include shivering, huddling together, reduced feed intake, reduced water intake, and seeking shelter. Cattle with wet or muddy coats are at higher risk. Monitor body condition and behavior daily. If cattle are losing condition or showing signs of respiratory disease, cold stress may be a contributing factor.

Should I bring cattle into a barn during extreme cold?

Not necessarily. Many feedlot cattle do well outside if they have adequate wind protection, dry bedding, and sufficient feed. Barns can create humidity and respiratory disease problems if not properly ventilated. Three-sided shelters with the open side facing south or east are often better than fully enclosed barns. Provide shelter but avoid overcrowding and poor ventilation.

What temperature is too cold for feedlot cattle?

Cattle with a dry winter coat can handle temperatures down to around 18 to 20 degrees Fahrenheit without extra energy needs. However, wind, moisture, and mud raise this threshold dramatically. A wet, muddy cow can experience cold stress at 40 degrees Fahrenheit. There is no absolute temperature that is too cold, but cold stress increases as temperatures drop and conditions worsen.

How do I prevent water from freezing in cattle tanks?

Use insulated, heated waterers designed for livestock. These maintain water above freezing with minimal energy use. For open tanks, use floating tank heaters or submersible heaters. Insulate exposed pipes with heat tape or foam insulation. Place waterers on the south side of buildings or windbreaks to reduce wind exposure.
