Windbreaks for Winter

Wind makes cold weather harder on cattle than temperature alone. A good windbreak reduces that load and can cut feed costs and stress.

Why wind matters in winter

Cattle can handle cold if they are dry, well fed and out of the wind. Wind strips away body heat and the effect is worse when hides are wet. A windbreak gives them a place to rest and conserve energy.

Cattle that are cold burn more energy to stay warm, which raises feed needs. That is one reason producers in cold regions invest in shelter and bedding.

Living windbreaks

Rows of trees and shrubs slow wind and trap snow in a controlled place. They take time to establish and need protection from cattle and competing weeds in the early years. Choose species suited to your soil and region.

Your NRCS office, state forestry agency or extension forester can help with species, spacing and design. Many offer technical help or planting advice, and program terms change, so ask what is available.

Keep young trees from becoming the weak link. Fence each row until the trees are tall enough to withstand rubbing, control grass and weeds around the base and replace losses promptly. Gaps in a row let wind funnel through at higher speed, so a missing tree matters more than it looks.

• Plan the layout before planting
• Protect young trees from cattle and weeds
• Use species suited to local soil and climate
• Allow time, because trees take years to work

Built windbreaks

Wooden or steel fences, panels and straw or hay bale walls provide immediate protection. A solid wall can create turbulence on the downwind side, so many designs use gaps or slats to let some air pass through.

Build windbreaks sturdy enough for wind loads and cattle pushing. Place them with the prevailing winter wind in mind, and keep them clear of feed bunks and water.

Straw, hay or panel designs also need regular checks. Bales shift, panels loosen and boards crack under a season of wind. Walk the line after each storm, fix gaps and tighten fasteners before the next one arrives.

Placement and snow

Wind flows over and around a windbreak, so protection extends a certain distance downwind. Place it so cattle can rest in that zone, and leave room for snow to drift where it will not bury water, gates or feed.

Keep access routes clear. A windbreak that traps snow across your feeding area makes chores harder. Walk the site after the first storm and adjust as needed.

If you are unsure, start with a short trial section and watch how snow and cattle behave behind it for a winter. Adjusting a small section is cheaper than rebuilding a long one, and the lessons carry over to the full design.

Bedding, feed and water

Shelter helps more when cattle also have dry bedding, enough feed and open water. A windbreak does not replace a good ration, so talk to your nutritionist about winter feed.

Consider the whole system: wind protection, dry resting area, drainage and reliable water. If any piece is missing, cattle may still struggle.

Check fences and panels for damage after storms, and replace broken boards. Loose panels can injure animals or blow into roads.

Using what you already have

Look around the ranch before buying anything. Existing buildings, terrain breaks, tree lines and stacked hay can all reduce wind. Many ranchers use round bales stacked in a line as a temporary wall, though bales left in place lose feeding value, so ask a nutritionist how to weigh that.

Walk the pasture during a windy day and note where animals bunch up. Cattle show you the calm spots, and the best windbreak sites are often next to them. Adding protection there costs less than rebuilding the whole layout.

• Observe where cattle shelter naturally
• Consider terrain, trees and buildings first
• Weigh the feed value of bales used as walls

Common mistakes

Common mistakes include placing the windbreak too close to the herd, building it too low and ignoring snow drift. Another is forgetting to maintain it.

Ask neighbors what has worked locally. Observing where cattle naturally shelter in storms is a free way to learn where a windbreak would help most.

Think about cost per year of useful life rather than purchase price alone. A cheap panel that blows over each winter costs more than a stronger one built once. Your accountant or lender can help you plan, and your NRCS office can explain technical help or cost-share options that may exist. Program terms change, so ask for current details.
