Livestock performance and survival is affected by wind and temperature. Knowing the purpose of the windbreak is vital to its success. These fences are typically used to prevent snow from drifting in dry lots and driveways further downwind or can be used to collect snow for ponds. Some windbreaks are used primarily as snowfences to collect snow directly on the downwind side. The windbreak will only be as good as it is designed and using the wrong design can cause more harm than good. Installing a windbreak needs to come with the end goal in mind. Constructing windbreaks increases protection for livestock. The presence of wind increases heat loss in livestock during the winter and can penetrate the hair coat allowing cold air to reach the skin, accelerating the loss of heat. Protection from the wind and snow is not always readily available from natural topography or living windbreaks such as tree lines or shrub rows. Shelter for livestock during the winter months can influence the success of calving and a livestock operation. Windbreaks can increase calving success by 2%.A straight, 25-33% porous windbreak will provide protection 8-10 times the height of the fence.
