Cattle Windbreak Design for Winter Shelter

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

Key Takeaways

Cattle experience cold stress when wind chill drops below their lower critical temperature (approximately 20-30°F for a dry winter coat), leading to increased energy expenditure for thermoregulation, reduced weight gain, and poorer body condition.
Windbreaks reduce wind speed by 50-80% for a leeward distance of 10-20 times their height, with optimal protection occurring within 5-10 times the height; a 50-60% porous design is superior to solid structures, preventing turbulent downdrafts.
Strategic placement 50-100 feet from feeding and water sources, oriented perpendicular to prevailing northwest or north winter winds, maximizes windbreak utilization and efficacy.
A 10-12 foot tall constructed windbreak or a mature tree windbreak (30-40 feet) is recommended to provide adequate protected area, with 20-30 square feet per cow recommended for three-sided sheds.
Wet hair significantly diminishes insulation, making wind protection critical during precipitation; monitoring body condition scores, feed intake, and cattle behavior are essential for assessing windbreak adequacy.
Immediate veterinary consultation is advised for signs of hypothermia, frostbite, or respiratory disease outbreaks in cattle, even with wind protection, as these indicate severe cold stress or secondary complications.

Winter weather takes a real toll on beef cattle. When wind chill drops below the lower critical temperature, cows burn extra energy just to stay warm, which means they eat more, gain less, and enter calving season in worse condition. A well designed cattle windbreak reduces cold stress, cuts feed costs, and improves animal welfare. This guide covers the science behind cold stress, step by step windbreak planning and construction, common design errors, and how to monitor whether your shelter is working. It is written for cow calf producers, stocker operators, and anyone planning a new cattle windbreak or improving an existing one.

At a Glance

Cattle experience cold stress when wind chill drops below the lower critical temperature, roughly 20 to 30 degrees Fahrenheit for cows with a dry winter coat.
A windbreak reduces wind speed by 50 to 80 percent for a distance of 10 to 20 times the windbreak height on the leeward side.
Solid fences create turbulent downdrafts. A 50 to 60 percent porous windbreak performs better for cattle comfort.
Place windbreaks 50 to 100 feet from feeding areas and water sources to encourage cattle use.
Orient windbreaks perpendicular to the prevailing winter wind direction, usually from the northwest or north.
A single row of trees or a slatted fence works well. Multiple rows of conifers give year round protection.
Provide 20 to 30 square feet of protected area per cow for a three sided shed, or rely on open windbreaks with adequate bedding.
Wet hair removes insulation value. Wind protection matters most when precipitation accompanies wind.
Monitor body condition scores, feed intake, and cattle behavior to judge if your windbreak is adequate.
Call a veterinarian if cattle show signs of hypothermia, frostbite, or respiratory disease despite wind protection.

Understanding Cold Stress in Cattle

Cattle are remarkably tolerant of cold when they have a dry coat, adequate nutrition, and shelter from wind. The trouble starts when wind strips away the insulating layer of air trapped in the hair coat. A cow that is comfortable at 20 degrees Fahrenheit with no wind can be severely stressed at 20 degrees with a 30 mile per hour wind. Wind chill is the real enemy.

The Lower Critical Temperature

Every animal has a thermoneutral zone, the range of temperatures where it does not have to expend extra energy to maintain body heat. For beef cattle, the lower critical temperature depends on coat condition, body condition, and feed intake. A cow with a heavy winter coat, good body condition, and a full rumen has a lower critical temperature around 18 to 20 degrees Fahrenheit. A thin cow with a wet, muddy coat has a lower critical temperature closer to 40 degrees.

When the effective temperature, which combines air temperature and wind chill, drops below the lower critical temperature, the cow must burn body fat or dietary energy to stay warm. This is called cold stress. For every degree below the lower critical temperature, a cow's energy requirement increases by roughly 1 percent. A 10 degree drop below the critical temperature raises energy needs by about 10 percent. Over a long winter, that extra energy demand translates directly into pounds of feed.

Wind Chill Effects

Wind removes the warm air trapped in the hair coat and accelerates heat loss from the skin surface. The effect is dramatic. At 20 degrees Fahrenheit with no wind, a cow loses heat at a manageable rate. Add a 20 mile per hour wind and the effective temperature plunges to near zero. The cow now needs substantially more energy just to maintain body temperature.

Wind also dries out the skin and eyes, increasing the risk of frostbite on ears, tails, and teats. Young calves are especially vulnerable because they have a higher surface area to body weight ratio and less body fat. A windbreak that cuts wind speed by half can raise the effective temperature by 10 to 20 degrees, which is often the difference between a cow maintaining condition and a cow losing weight.

Precipitation and Hair Coat Insulation

Rain and wet snow are more dangerous than dry cold. A wet hair coat loses most of its insulating value because water conducts heat away from the body far faster than air. A cow with a dry, fluffed coat can handle extreme cold. The same cow with a soaked coat can become hypothermic at temperatures well above freezing.

This is why windbreaks matter most during storms. A windbreak cannot keep rain off a cow, but it can reduce the wind driven rain and snow that soaks the coat. Combined with a roofed area or natural tree cover, a windbreak provides a dry zone where cattle can recover from exposure.

Body Condition and Cold Tolerance

Thin cows are far more vulnerable to cold stress. Body fat acts as insulation and as an energy reserve. A cow with a body condition score of 3 or lower has less fat to burn and less insulation against cold. The same wind that a BCS 6 cow shrugs off can be life threatening to a BCS 3 cow.

Cattle that are accustomed to cold gradually develop a thicker coat and higher metabolic rate. This acclimatization takes several weeks. A sudden cold snap in early fall, before cattle have grown their full winter coat, can cause more stress than a much colder spell in January.

Planning Your Cattle Windbreak

Good windbreak design starts with observation. Walk your pasture on a windy day and note where cattle gather. They already know where the best natural shelter is. Look for the spots where snow drifts form, where trees provide cover, and where cattle bunch up against fences. These observations tell you where a windbreak will be used.

Assess Prevailing Winds

Most of the northern United States and Canada experience prevailing winter winds from the northwest or north. But your specific location may differ. A valley may channel winds from a different direction. Hills and tree lines can deflect wind. Spend time on your farm during winter storms and record wind direction. Use a simple weather station or observe the direction snow drifts form.

The windbreak must be oriented perpendicular to the prevailing wind direction. If winter winds come mostly from the northwest, build the windbreak running northeast to southwest. If winds shift between north and west, a windbreak angled to cover both directions works better than a single straight line.

Determine the Protected Zone

A windbreak reduces wind speed on the leeward side for a distance of 10 to 20 times the windbreak height. A 12 foot tall fence protects cattle for about 120 to 240 feet downwind. The strongest protection is within 5 to 10 times the height, so a 12 foot fence gives the best shelter within 60 to 120 feet of the fence.

Trees grow taller over time, so a tree windbreak eventually protects a larger area. A mature conifer windbreak at 40 feet tall can protect an area 400 to 800 feet downwind. Plan your layout with the mature height in mind, not the height at planting.

Match Windbreak Type to Your Operation

There are three main types of cattle windbreaks: living windbreaks of trees and shrubs, constructed fences and panels, and natural landforms such as hills and existing tree lines. Many operations combine two or more types.

Living windbreaks are the most durable and cost effective over the long term. They require several years to become established but then provide decades of service. Constructed windbreaks give immediate protection and can be moved or modified. Natural landforms cost nothing but are fixed in location.

Your choice depends on your timeline, budget, and pasture layout. A stocker operation that moves cattle frequently may prefer portable panels. A cow calf operation with permanent pastures is better served by a tree windbreak.

Consider Cattle Flow and Facility Layout

A windbreak only works if cattle use it. Place windbreaks near water, feed, and handling facilities. Cattle will not walk far from feed and water just to escape wind. The ideal setup has the windbreak between the prevailing wind and the feeding area, so cattle can eat in the sheltered zone.

If you feed hay in a specific area, position the windbreak 50 to 100 feet upwind of the hay rings. This creates a protected feeding zone. Cattle will stand in the sheltered area while eating and will return to it between trips to water.

Water sources need protection too. A water tank in an exposed location forces cattle to leave the shelter to drink. If possible, position the water tank within the protected zone or provide a separate windbreak near the tank.

Plan for Snow Drift Management

Windbreaks catch snow. That is part of their job, but drifting snow can bury fences, block gates, and make feeding areas inaccessible. A porous windbreak deposits snow over a wider area rather than in a single deep drift. This is another reason to avoid solid fences.

Place windbreaks at least 100 feet from roads, gates, and feeding areas that must stay open. If snow accumulation is a recurring problem, plan for a snow fence or additional windbreak further upwind to catch snow before it reaches your working areas.

Constructed Windbreak Options

Constructed windbreaks provide immediate protection and are often the best choice for operations that need shelter this winter. Several designs work well for cattle.

Slatted Wood Fence

A slatted wood fence is the classic cattle windbreak. Use boards or planks with gaps between them so the fence is 50 to 60 percent solid. The gaps allow some wind to pass through, which reduces turbulence on the leeward side.

Build the fence 10 to 12 feet tall. Use pressure treated posts set at least 3 feet deep, spaced 8 to 10 feet apart. Attach horizontal rails or vertical boards. Common designs use vertical boards with 2 to 4 inch gaps, or horizontal boards spaced 4 to 6 inches apart.

The key is the porosity. A solid fence creates a vacuum effect on the leeward side that pulls wind down and creates turbulence. Cattle avoid the turbulent zone. A porous fence slows wind without creating the downdraft, and cattle will stand right behind it.

Metal Panel Windbreak

Metal livestock panels, the same type used for corrals, can be mounted on posts to create a windbreak. These panels are typically 16 feet long and 5 feet tall. Stack two panels vertically to reach 10 feet. The gaps between the panels and the corrugated surface provide some porosity.

This is a fast and inexpensive option. It works well for temporary windbreaks around feeding areas. The main drawback is that metal panels are more solid than ideal, so they create more turbulence. Adding gaps between panels or using panels with perforations improves performance.

Snow Fence and Fabric Windbreak

Commercial snow fence material, which is typically wooden slats or plastic mesh with 50 percent porosity, can be mounted on posts to create a windbreak. This material is lightweight, inexpensive, and effective. It is not as durable as wood or metal but works well for seasonal protection.

Heavy duty woven fabric windbreak material is also available from agricultural suppliers. This fabric is designed for livestock shelter and is available in rolls. Mount it on a post and cable system. The fabric provides good wind reduction while allowing some air passage.

Portable Windbreak Panels

For operations that rotationally graze or move cattle frequently, portable windbreak panels are a practical choice. These are typically 10 to 12 foot long panels mounted on skids or wheels. They can be moved with a tractor or ATV to wherever cattle are located.

Portable panels are more expensive per foot than permanent fences but offer flexibility. They also allow you to experiment with placement before committing to a permanent structure. Many producers use portable panels for calving areas, moving them to protect each new calf crop.

Three Sided Shed

A three sided shed provides the highest level of protection because it blocks wind and provides a roof. The open side faces away from the prevailing wind. Sheds are more expensive than open windbreaks but are essential for calving areas and for operations in extreme cold regions.

Build the shed with the open side facing south or east, away from the prevailing northwest wind. Provide 20 to 30 square feet per cow. The shed should be deep enough that cattle can stand fully inside, typically 16 to 24 feet deep. The roof should have adequate slope to shed snow and should extend beyond the walls to keep precipitation out.

Bedding is critical in a shed. Provide straw, wood shavings, or other absorbent material. Clean out wet bedding regularly. A shed with wet, dirty bedding can cause more problems than no shed at all because it promotes foot rot and respiratory disease.

Living Windbreak Design

Tree windbreaks are the most cost effective long term solution for cattle shelter. A well designed tree windbreak lasts 50 years or more with minimal maintenance. The main drawback is the establishment period, which can take 5 to 10 years before the windbreak provides meaningful protection.

Tree Species Selection

Choose tree species that are hardy in your region, grow well in your soil, and provide dense winter cover. Evergreen conifers are the best choice because they retain their needles through winter. Good options include:

Eastern red cedar is hardy, drought tolerant, and grows in poor soils. It provides dense cover but can be slow growing. It is a good choice for the Great Plains and Midwest.

Ponderosa pine is a tough, adaptable tree that handles wind and drought. It grows faster than cedar and provides good cover. It works well in the western states.

White spruce and Norway spruce are excellent windbreak trees for the northern states and Canada. They grow well in cold climates and provide dense, low growing branches that reach the ground.

Austrian pine is a good choice for the central and southern plains. It tolerates heat, drought, and alkaline soils.

In addition to the main windbreak rows, plant a few deciduous trees and shrubs. These fill gaps, provide wildlife habitat, and add diversity. However, deciduous trees lose their leaves in winter, so they do not provide winter wind protection on their own.

Windbreak Layout and Spacing

A single row of conifers can provide adequate wind protection if the trees are dense and well maintained. For better protection, plant multiple rows. A typical design uses three to five rows.

Space rows 12 to 20 feet apart. Within a row, space trees 8 to 12 feet apart. The exact spacing depends on the species and how large the trees grow at maturity. Dense spacing gives quicker protection but requires thinning as trees grow.

Plant the windbreak perpendicular to the prevailing wind. The windbreak should extend well beyond the area you want to protect. A good rule is to make the windbreak at least 50 feet longer than the protected area on each end.

Establishment and Care

Tree planting is best done in early spring or fall when soil moisture is adequate. Prepare the planting site by controlling weeds and grass before planting. Grass competition is the leading cause of young tree death.

Use tree shelters or weed barrier fabric to protect young trees from grass, wind, and animal damage. Fence the windbreak to keep cattle out until trees are established. Cattle will browse and trample young trees, killing them quickly.

Water young trees during dry periods for the first two to three years. After establishment, most windbreak trees are drought tolerant and need no supplemental water.

Plan to prune or thin the windbreak as trees mature. Dense, crowded trees become weak and may break in storms. Remove dead or diseased trees promptly.

Combining Trees and Fence

Many operations combine a constructed fence with a tree windbreak. The fence provides immediate protection while the trees grow. Once the trees are established, they take over the windbreak function and the fence can be removed or left in place.

This approach is cost effective because you get protection from year one and a permanent solution within a decade. Position the fence slightly upwind of the tree row so the fence takes the initial wind force while the trees establish.

Windbreak Placement Strategies

Where you place the windbreak is as important as what you build. The goal is to create a sheltered zone where cattle can rest, feed, and access water without being exposed to wind.

Distance from Feeding Areas

Place the windbreak 50 to 100 feet upwind of your feeding area. This puts the sheltered zone directly over the feed. Cattle will stand in the protected area while eating. If the windbreak is too far from the feed, cattle will not use it. If it is too close, snow drifts may bury the feed.

For hay rings or bale feeders, position the windbreak so the feeding area is within 5 to 10 times the windbreak height on the leeward side. For a 12 foot fence, that puts the ideal feeding zone 60 to 120 feet downwind.

Orientation to Water

Cattle need water every day, even in winter. If the water source is exposed, cattle will leave the shelter to drink and then stand in the wind while they are at the tank. Position the water tank within the sheltered zone or provide a small windbreak specifically around the tank.

A simple approach is to place a portable windbreak panel between the prevailing wind and the water tank. This gives cattle a sheltered spot to stand while drinking. Some producers build a small roof over the water tank to keep snow out and reduce freezing.

Calving Area Protection

Calving areas need the highest level of protection. Newborn calves are extremely vulnerable to cold stress. A calf born in a 20 degree wind can die of hypothermia within hours if it cannot dry off and nurse.

Place calving areas in the most sheltered location available. A three sided shed is ideal. If you use an open windbreak, position it close to the calving area and provide plenty of bedding. Have a plan for bringing calves indoors if severe weather hits.

Multiple Windbreaks for Large Pastures

A single windbreak only protects a limited area. In a large pasture, cattle may not walk a mile to reach the windbreak. Consider multiple windbreaks distributed across the pasture so cattle are never far from shelter.

A good rule is to place windbreaks so that no point in the pasture is more than a quarter mile from shelter. This may mean two or three windbreaks in a large pasture. Smaller, strategically placed windbreaks are more effective than one large windbreak in a corner.

Common Windbreak Design Mistakes

Many cattle windbreaks fail because of simple design errors. Knowing these mistakes helps you avoid them.

Building a Solid Fence

The most common mistake is building a solid, airtight fence. Solid fences create strong turbulence on the leeward side. Wind hits the fence, is forced upward, then drops down behind the fence in a violent eddy. Cattle feel this downdraft and avoid the area immediately behind the fence.

The solution is porosity. Build the fence so 40 to 50 percent of the surface is open. This allows wind to pass through and creates a calm zone downwind. The protected area is actually larger behind a porous fence than behind a solid fence.

Making the Windbreak Too Short

A windbreak that is only 5 or 6 feet tall protects a very small area. The protected zone extends 10 to 20 times the height, so a 6 foot fence protects only 60 to 120 feet. This is barely enough for a few cattle.

Build windbreaks at least 10 to 12 feet tall. For tree windbreaks, plant species that will reach 30 to 40 feet at maturity. Taller windbreaks protect more area and provide better shelter.

Placing the Windbreak Too Far from Cattle Activity

A windbreak in the middle of a pasture that cattle never visit provides no benefit. Cattle are creatures of habit. They spend time where feed and water are located. Place windbreaks near these activity centers.

If you feed hay in one location all winter, build the windbreak there. If you rotate feeding areas, use portable windbreaks that move with the feed.

Forgetting About Snow Drifts

All windbreaks catch snow. A solid windbreak creates a deep drift directly behind the fence. This drift can bury the fence, block gates, and make the sheltered area unusable.

Porous windbreaks spread snow over a wider area, creating shallower drifts. Place windbreaks far enough from roads and gates that drifting snow does not block access. Plan to plow or clear snow from critical areas.

Using Windbreaks That Are Too Dense

A tree windbreak that is too dense creates the same problem as a solid fence. The trees block all wind, creating turbulence on the leeward side. The windbreak also catches snow in a narrow band, creating deep drifts.

Thin tree windbreaks to maintain 40 to 60 percent density. Remove lower branches if they create a solid wall. The goal is to slow wind, not stop it completely.

Ignoring the Water Source

Cattle will not use a windbreak if they have to cross an exposed area to reach water. A windbreak that protects the feeding area but leaves the water tank exposed is only half effective.

Provide wind protection at the water source. This can be a small windbreak panel, a natural tree line, or a roof over the tank. Cattle that can access water without leaving the sheltered zone will spend more time in the protected area.

Building Windbreaks Only for the Worst Storm

Design your windbreak for the average winter day, not just the worst blizzard. Cattle need shelter from the wind every day, not only during storms. A windbreak that is only useful in a blizzard will not help cattle maintain condition during the long, windy weeks of a normal winter.

Aim for a windbreak that cattle use daily. If cattle are not standing behind the windbreak on a normal windy day, the design or placement is wrong.

Decision Thresholds for Windbreak Investment

Not every operation needs the same level of wind protection. Your location, herd size, and calving season all influence how much you should invest in windbreaks.

Climate Zone Considerations

Operations in the northern plains and mountain west face more severe winter weather and need more substantial windbreaks. A cow in North Dakota experiences far more cold stress than a cow in Tennessee. Match your windbreak investment to your local climate.

If your average winter temperature is below 20 degrees Fahrenheit and winds regularly exceed 15 miles per hour, invest in a high quality windbreak. If winters are mild with temperatures rarely below freezing, a simple windbreak or natural tree line may be sufficient.

Herd Size and Calving Season

Large herds need more protected area than small herds. A windbreak that shelters 50 cows may be inadequate for 200 cows. Calculate the protected area and match it to your herd size.

Calving season is the most critical time for wind protection. If you calve in January or February, invest in a three sided shed or high quality windbreak. If you calve in April or May, when weather is milder, a basic windbreak may be enough.

Feed Cost Analysis

Windbreaks pay for themselves through reduced feed costs. A cow under cold stress eats more to maintain body temperature. Reducing cold stress reduces feed intake.

Estimate the potential savings: if a windbreak reduces cold stress enough to cut feed intake by 5 percent, and you feed 100 cows for 100 days, the savings can be substantial. Compare this to the cost of the windbreak to determine your payback period.

Temporary versus Permanent Solutions

If you need protection immediately, build a temporary windbreak from panels or snow fence. This gives you time to plan and plant a permanent tree windbreak. Many operations use temporary windbreaks for several years while trees become established.

Temporary windbreaks are also useful for testing placement. Build a portable windbreak and observe where cattle use it. Once you know the best location, install a permanent structure.

Monitoring Windbreak Effectiveness

A windbreak is not a set and forget investment. Monitor its effectiveness throughout the winter and make adjustments as needed.

Observe Cattle Behavior

The best indicator of windbreak effectiveness is cattle behavior. Cattle that are comfortable will spread out and rest in the sheltered zone. Cattle that are cold will bunch up, stand with their tails to the wind, and show signs of distress.

Walk your pasture on windy days and observe where cattle are standing. If they are not using the windbreak, something is wrong. The windbreak may be in the wrong location, too short, or too dense.

Track Body Condition Scores

Monitor body condition scores through the winter. Cattle that are maintaining or gaining condition are getting adequate protection and nutrition. Cattle that are losing condition despite adequate feed may be suffering from cold stress.

Body condition scoring is a simple visual assessment. Score cows on a 1 to 9 scale, with 1 being emaciated and 9 being obese. A score of 5 is ideal for most beef cows. Check body condition at the start of winter and again at calving.

Monitor Feed Intake

Track how much feed cattle consume. An unexpected increase in feed intake can indicate cold stress. Cattle eating more but not gaining condition are burning energy to stay warm.

If feed intake rises sharply during cold snaps, your windbreak may not be providing adequate protection. Consider adding supplemental wind protection or increasing the energy density of the ration.

Check for Signs of Cold Stress

Learn to recognize the signs of cold stress in cattle. Early signs include shivering, huddling, and reduced activity. More severe signs include frostbite on ears and teats, lethargy, and reluctance to move.

Cattle with frostbitten ears may have swollen, discolored tissue that later turns black and sloughs off. Frostbitten teats can prevent calves from nursing. These are serious conditions that require veterinary attention.

Document Winter Conditions

Keep a simple log of winter weather conditions and cattle response. Note the temperature, wind speed, precipitation, and how cattle behaved. This record helps you identify patterns and make informed decisions about windbreak improvements.

Record the date, weather conditions, and any observations about cattle behavior or condition. Over several winters, this log becomes a valuable planning tool.

When to Call a Veterinarian or Extension Agent

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

Signs of Hypothermia

Hypothermia is a medical emergency. A cow with hypothermia has a body temperature below 100 degrees Fahrenheit. Signs include severe shivering that progresses to stiffness, weakness, and unconsciousness. The cow may stop eating and drinking and may isolate herself from the herd.

If you suspect hypothermia, move the cow to a warm, dry area immediately. Provide warm water and high energy feed if the cow can eat. Call a veterinarian right away. Hypothermia can be fatal if not treated promptly.

Frostbite Cases

Frostbite occurs when tissue freezes, usually on the ears, tail, teats, or scrotum. The affected tissue appears pale or waxy at first, then becomes swollen and painful as it thaws. In severe cases, the tissue dies and sloughs off.

Mild frostbite may heal on its own, but severe frostbite requires veterinary treatment. A veterinarian can assess tissue damage, manage pain, and prevent infection. Frostbitten teats are especially serious because they prevent calves from nursing.

Respiratory Disease Outbreaks

Cold stress weakens the immune system and makes cattle more susceptible to respiratory disease. If multiple cattle develop coughing, nasal discharge, or labored breathing, call a veterinarian. Respiratory disease can spread quickly through a herd and requires prompt treatment.

Young calves are especially vulnerable. Respiratory disease in calves can cause permanent lung damage and reduced performance. Early veterinary intervention is critical.

Extension Agent Consultation

Your local extension agent can provide valuable guidance on windbreak design, tree species selection, and winter cattle management. Extension agents have access to research based information and local climate data.

Contact your extension office before building a windbreak. They can help you select appropriate tree species, calculate protected area, and connect you with cost share programs. Many states offer financial assistance for conservation practices like windbreaks.

Cost Share and Conservation Programs

Several federal and state programs provide financial assistance for windbreak establishment. The Natural Resources Conservation Service, part of the USDA, offers cost share through the Environmental Quality Incentives Program. This program can cover a portion of the cost of planting trees and establishing windbreaks.

Your local NRCS office can provide information about available programs in your area. Many states also have conservation districts that offer tree seedlings at low cost. These programs can significantly reduce the cost of establishing a living windbreak.

Frequently Asked Questions

How tall should a cattle windbreak be?

A cattle windbreak should be at least 10 to 12 feet tall for constructed fences. This height protects an area 100 to 240 feet downwind. Tree windbreaks should reach 30 to 40 feet at maturity for maximum protection. Taller windbreaks protect a larger area and provide better shelter, so build as tall as practical for your situation.

What is the best material for a cattle windbreak?

The best material depends on your needs. Slatted wood fences are durable and effective when built with 50 to 60 percent porosity. Metal panels are quick to install and work well for temporary windbreaks. Heavy duty fabric windbreak material is lightweight and effective. For a permanent solution, evergreen trees are the most cost effective over the long term.

How far from the windbreak should I place hay feeders?

Place hay feeders 50 to 100 feet downwind of the windbreak. This puts the feeders within the strongest protected zone, which is 5 to 10 times the windbreak height. For a 12 foot fence, the best zone is 60 to 120 feet downwind. This distance also keeps snow drifts from burying the feeders.

Do cattle need a roof or just a windbreak?

Cattle generally do not need a roof if they have a good windbreak and a dry place to lie down. Their winter coat provides excellent insulation when dry. A roof is most important for calving areas and for operations in regions with heavy precipitation. A three sided shed with a roof is the best protection for newborn calves.

How many rows of trees do I need for an effective windbreak?

A single row of dense conifers can provide adequate protection, but three to five rows are better. Multiple rows create a thicker, more effective windbreak and provide better protection if one row suffers damage. Space rows 12 to 20 feet apart and trees within rows 8 to 12 feet apart.

Will a windbreak reduce my feed costs?

Yes, a well designed windbreak can reduce feed costs by lowering cold stress. Cattle under cold stress eat more to maintain body temperature. By reducing wind exposure, you lower the energy cattle need to stay warm. Savings depend on your climate and herd size, but many producers see a meaningful reduction in winter feed intake.

How do I keep snow drifts from blocking my windbreak?

Use a porous windbreak design to spread snow over a wider area. Solid windbreaks create deep, narrow drifts while porous windbreaks create shallower drifts over a larger area. Place windbreaks at least 100 feet from roads, gates, and feeding areas. Plan to plow critical areas after major snow events.

Can I use round bales as a temporary windbreak?

Yes, round bales can serve as an emergency windbreak. Line up bales in a row perpendicular to the prevailing wind. This provides immediate protection, though the gaps between bales let wind through. Place bales two rows deep for better protection. This is a temporary solution, not a substitute for a proper windbreak.
