What Do Farmers Do With Cows in the Winter? (The Complete Guide)

Winter brings freezing weather to your dairy farm. Cold stress¹ drops milk production and harms animal health. But with the right management and equipment, you can keep your cows safe.

In winter, farmers protect cows by adjusting their diet for extra energy, providing heated drinking water, and managing barn ventilation. They use thick, dry bedding to prevent cold stress and run manure scrapers regularly. Good farm equipment ensures cows stay warm, healthy, and productive during freezing months.

Winter is a tough time for dairy farming. Let us look at the exact steps and tools you need to protect your herd from the cold.

How Do You Manage Barn Ventilation and Temperature in Winter?

Sealing the barn keeps the cold out. But tight spaces trap moisture and hurt cow lungs. You must balance warmth with fresh air to stop sickness.

Farmers manage winter ventilation by opening windows during the warmest part of the day, usually between 11 AM and 2 PM, for one to two hours. For calf barns, only sunny-side windows open. This controls humidity at 60-70% while keeping the temperature around 15°C.

You cannot just focus on keeping the barn warm. You must also remove bad air. If you see water drops on the windows, the humidity is too high. High humidity causes lung problems in cows. We suggest putting barn doors on one side. You can use trees and vines as a wind barrier outside. This blocks the cold wind but still lets the air move.

You should use a roll-up curtain system with an extra plastic film layer outside. This helps keep the barn temperature near 15°C. At NexAgri, we help large farms build these systems. Before winter comes, you must check your equipment. You must make sure the real temperature matches your system settings. We want to keep the humidity between 60% and 70%.

If you seal the barn too tight, the air gets dirty. The cows breathe in bad air and get sick. You must open the windows to let fresh air in. But you cannot open them all the time. You should only ventilate when the sun is out. The best time is between 11 AM and 2 PM. This is when the outside temperature is the highest. You should keep the windows open for one to two hours. You must change this time based on the weather. If you have a calf barn or a pregnant cow barn, only open the windows on the sunny side. If you have a fattening barn, you can open the upper windows on the north and south sides. Do not ventilate when it is very cold in the early morning or late at night.

What Changes Do Cows Need in Their Winter Diet and Water?

Freezing weather drains a cow's energy. If you feed them the same summer diet, they will lose weight and produce less milk. You must change their food and water.

In winter, a cow's food intake increases by 10% to 15%. Farmers must provide extra energy in the feed for every degree the temperature drops. They also use heated stainless steel troughs to stop drinking water from freezing, ensuring cows stay hydrated and healthy.

Cold weather makes cows work harder to stay warm. For every one degree drop in temperature, a cow needs more energy. You must feed them more. In winter, a cow eats 10% to 15% more food than in summer. You should use a farm management software to track this. You can follow professional advice to mix the right feed. Large farms use our heavy-duty TMR feed mixers to mix this extra feed well.

If the cows are cold, they use their food energy to stay warm. They do not use it to make milk. You must give them more energy. You must look at the thermometer every day. If the temperature goes down, the food energy must go up.

Water is just as important as food. Cows will not drink freezing water. If they do not drink, they will not eat. Then they will not make milk. You must use heated drinking troughs. Our factory produces high-quality stainless steel heated troughs for wholesale buyers. When you install heating devices, you must strictly separate the electricity from the water. This stops dangerous electric shocks. You must check the wires on these troughs every week. Water and electricity are a bad mix. You must keep them far apart. If a wire breaks, the cow can get a shock and stop drinking forever.

How Do You Prevent Cold Stress and Injuries in the Barn?

Icy floors cause bad falls. Wet resting areas lead to severe cold stress. If cows cannot lie down comfortably, their rumination stops and their health fails quickly.

Farmers prevent cold stress by adding thick sand and straw bedding so cows lie down more. They use animal-safe ice melt on icy paths. They also ensure manure scrapers run at least twice a day to keep the alleys clean, dry, and safe from slippery ice.

A comfortable cow makes more milk. In extreme cold weather, you must make the cows lie down more. You can add extra sand and straw to their resting beds. We recommend using lying time monitors every day. These monitors check how long the cows sleep. The bedding must stay very dry and clean. This helps their stomachs work well.

Cold stress¹ happens when a cow gets too cold for too long. This makes her weak and sick. The best way to stop cold stress is to give her a warm bed. Thick sand and straw hold the heat well. When the cow lies down, she rests her feet and makes more milk. You must check the beds every single day. If the bed is wet, you must change it right away. A wet bed is colder than a dry floor.

Ice is a very big danger on the farm. If the road freezes, you must use an animal-safe ice melt. You can never let your cows slip and fall. Regular salt can hurt their hooves, so you must use the safe kind. You also need to keep the barn floors clean. We suggest running automatic manure scrapers at least two times a day. We manufacture these scrapers, so we know that clean floors mean healthy hooves. If manure freezes on the floor, the cows cannot walk. You also need good teamwork on the farm. You must coordinate your vet and breeding workers. You must reduce the time cows spend locked in our headlocks to keep them comfortable.

How Should You Adjust Milking Routines in Freezing Weather?

Milking in winter brings a hidden danger. Wet teats exposed to freezing air will crack and bleed. This pain ruins milk let-down and leads to dangerous infections.

During winter milking, farmers must make sure the cow's teats are completely dry before letting them leave the parlor. This simple step stops frostbite and cracking. Keeping the milking parlor warm and dry also protects the cows and keeps the equipment working perfectly.

The milking parlor needs special care in the cold. The biggest risk to your cows is frostbite on their teats. After you finish milking the cow, you must wait. Do not let the cow walk out into the cold wind right away. You must wait until her teats are completely dry. If you use a dip, use a special winter dip. This keeps the skin soft.

Winter milking takes more time. You cannot rush the process. When the teat is wet, the cold wind turns the water into ice. The skin cracks and bleeds. This hurts the cow very much. She will not let her milk out the next time. You must dry the teat with a clean towel. You must keep her in the warm parlor until she is fully dry.

At NexAgri, we build complete Herringbone and Rotary milking parlors for big farms. We know that cold weather affects the milking machines too. You must check your vacuum systems more often. You must check the pulsators and claws. Cold weather makes metal and rubber act differently. The vacuum pump works harder in the cold. Cold rubber tubes can become very stiff. The rubber liners get hard and lose their shape. A hard liner hurts the cow and slows down the milking. You should replace old rubber liners before winter starts. This keeps the milking process gentle and safe.

Conclusion

Winter farming demands careful ventilation, increased feeding, heated water, and dry bedding. By using the right equipment and management steps, you can keep your cows healthy and highly productive.
