  • Cold and high winds decrease cattle production due to stress. Wind chill can have a more serious effect than extreme cold. At -18oC, a 22 km/hr wind will make it feel like -34oC.
  • Wind increases heat loss and increases the amount of feed required by cattle for maintenance and gain. Livestock are less efficient at converting feed to energy under prolonged exposure to cold. By using wind protection, you can reduce these losses by up to 50%.
  • Permanent fences, portable fences and shelterbelts can be used to protect loafing, watering and feeding sites.
  • The use of portable windbreak fences allows you to winter livestock on any field with an adequate water or snow source, and control the distribution of nutrients around the field with each move.
  • The most effective windbreak fences are 20% porous and allow some wind to filter through to reduce a downside vacuum. This provides better downwind protection than a solid fence of the same height. Openings greater than 10 inches or boards greater than 10 inches wide are not recommended.
  • A 75-80% density windbreak that is 8 feet high decreases the wind velocity by 15% on the downwind side for 32 feet (4H) and 25% at 80 feet (10H), with some wind protection as far as 12 times the fence height downwind.
  • The amount of hay hauling may be reduced as windbreaks and livestock can be moved to parcels of land adjacent to, or directly on to, hay fields where the bales can be fed as needed.
  • Fall and winter grazing practices such as stockpiling perennial forage, swath grazing and crop residue grazing can be used on open parcels of land that do not have natural shelter.
  • Producers can winter livestock away from riparian areas that have excellent natural shelter, but are environmentally sensitive.
  • Livestock can be wintered on the same site for the entire winter season. In spring, the portable windbreaks can be moved, allowing unhindered access for manure removal equipment.
  • Portable windbreaks can be moved when snow accumulates, eliminating the need for snow removal.
  • On calving grounds, disease build-up can be reduced when the location of the site is moved on a regular basis.
  • Shelterbelts are natural windbreaks that are very effective at protecting cattle as well.
