When the mercury is dropping and the wind is blowing a gale, most people would rather be indoors than outside braving the elements. The same is often true of livestock. I am among those who prioritize keeping all of my animals as comfortable as possible throughout all seasons, and have developed a repertoire of effective ways to keep them warm during the cold of winter. Even if your motivation to keep livestock warm is centered more on avoiding a drop in production or merely basic survival, the following list is a good reference for livestock safety in winter.
1. Time grooming and treatments with intentionality. Avoid shearing and trimming coats when cold weather is approaching, of course. But beyond that, it may not be a bad idea to limit shots, hoof-trimming, and other routine procedures in winter as much as possible. Anything that causes an animal stress can detract from the energy it uses to stay warm and healthy. I am not suggesting a moratorium on livestock handling, but only to try and do the bulk of it in late fall and early spring so as to keep it to a minimum in winter.
2. Give easy access to shelter. Laws in some states specify minimum housing required for livestock. Whether a certain level of shelter is mandated or not, even animals that are adapted to cold often do better if they can get in out of the wind and precipitation. Insulation is great, but could be considered extravagant. If a barn is well-insulated and airtight, it is important to allow for ventilation in order to prevent excess moisture buildup inside and keep healthy air circulating.
3. Provide plenty of clean dry bedding. Depending upon your infrastructure and the type of animals you have, this may include cleaning out waste every day or two before applying fresh shavings, straw or other litter.

Conversely, the dung of certain livestock such as goats and sheep is sufficiently small and dry that it can be allowed to build up over the winter. This creates a thick mattress of composting material which contributes to the animals’ comfort. Whether you clean out regularly or not, a clean dry space is important.
4. Increase protein intake. For ruminants and other herbivores such as cattle, sheep and goats, this is usually accomplished by way of grain. This can be done by switching up to a higher-percentage grain, adding a top-dress of kelp or other supplement, or increasing the amount of grain. Protein for omnivorous animals like pigs and poultry can be fed meat fats as well.
5. Allow communal living. Animals will group together for warmth if they need to do so. Snuggling into the hay, or even moving about in close proximity to one another, will help them create and retain body heat. Sometimes the animals within a herd need to be split up for management reasons, but they all need at least one or two buddies during frigid conditions.
6. Allow them to rely on their own instincts. Animals will gravitate toward warm areas on a cold day if they can. If they have access to sunny barn windows, draft-free zones, or spaces up against buildings or solid fences that reflect the sun, you are likely to find them availing themselves of nature’s hotspots.
7. Use a plastic livestock curtain in doorways. These vertical strips of heavy plastic purchased from farm equipment catalogs — or made at home using clear shower curtains — hang in doorways and are effective barriers to inclement weather. They allow animals to move freely in and out, are loose enough to provide crucial ventilation indoors, limit snowfall beyond the threshold, draw the sun’s heat on cold clear days, and help retain interior warmth.
8. Maintain some dry ground outdoors if possible. Livestock often balk at fording deep snow, possibly because as prey animals they do not want to get bogged down, or because their instincts cause them to avoid expending unnecessary energy, or perhaps they just do not like it. A roofed outdoor area, plowed paddock, or even some shoveled paths to their favorite locations are a plus.
9. Use added heat if absolutely necessary. The best way to do this is to provide heavy-duty water jugs — tightly closed and kick- and chew-proof — of hot water, or bricks heated near the wood stove, for the most frigid snaps. Another way is by using heat lamps, but only with extreme caution. I see at least one news story every winter about a barn fire that started from heat lamp use. It is so easy to make a mistake or for accidents to occur — they end up too close to combustible materials, or the hanging apparatus breaks, or animals knock them over or chew the cords, or the outlets are bad. Except for extenuating circumstances — compromised newborns, animals that are sick or must be isolated, or other extreme situations — the use of heat lamps is probably not worth the risk. Choosing the right breeds, maintaining infrastructure, and facilitating a way for the animals to keep themselves warm naturally are all better choices. If heat lamps must be used, it is vital to use only those that are high quality and are designed for use in a barn.
10. Choose the best breeds for your climate. Some breeds of livestock are more naturally suited to extreme temperatures than are others. Animals with thick coats or other cold-weather adaptations are more likely to thrive in colder regions, but obvious physical attributes do not always tell the whole story. It is helpful to consider where the breed originated or was developed — did it come from the desert, or the tundra? Another consideration is the size of the animal: Very generally speaking, larger animals tolerate cold better than smaller ones, due to the ratio of skin surface to body mass.
Short of bringing livestock into the house, these are some of the best ways to help keep farm animals safe and comfortable in the harshest of winters. Due diligence and a little forward thinking can work together to create an atmosphere that will provide the best possible care for animals and peace of mind for owners.
