Winter is a busy period for cattle farmers and one of the most challenging times for calves during their first months of life. Young animals have weaker immunity and have more difficulty maintaining their body temperature. A poorly prepared barn can quickly lead to respiratory diseases and diarrhea. The good news is that most problems can be prevented by taking care of the barn and preparing a prevention plan well before winter, preferably in autumn.

The Microclimate in the Barn Is More Important Than a High Temperature

Many farmers tightly close the barn in winter to keep it warm. This is a common mistake. Lack of ventilation increases humidity and ammonia levels, which irritates calves’ respiratory tracts and promotes the growth of microorganisms. The barn should be well ventilated, but without drafts at the level where the animals are lying down. A dry, thick layer of bedding is also essential, allowing the calf to “burrow” into it.

During severe frosts, calf jackets can be helpful. In cold weather, it is also important to remember that calves have higher energy requirements, which means providing an appropriately increased amount of milk or milk replacer. Animals must also have constant access to unfrozen water.

Symptoms That Should Not Be Ignored

Respiratory diseases in calves can develop quickly, and delayed treatment can permanently weaken the animal and negatively affect its growth rates. A veterinarian should be called if you notice:

• coughing and discharge from the nose or eyes,
• rapid or labored breathing,
• fever, lethargy, and drooping ears,
• reluctance to drink milk or eat,
• diarrhea or clear signs of dehydration (sunken eyes, a dry nose).

A quick response when the first calf becomes ill can often help limit the spread of disease throughout the group.

Prevention Planned Together with a Veterinarian

It is best to prepare for winter before the frosts arrive. It is worth discussing a vaccination program against respiratory diseases and diarrhea with your veterinarian. Equally important is ensuring that calves receive colostrum during the first hours of life, as this plays a crucial role in developing immunity during the following weeks.

An autumn farm visit is also a good opportunity to assess the buildings, ventilation system, and feeding program, as well as to establish what steps should be taken if the first cases of illness appear in the herd.

How Does VetFile Make Herd Care Easier?

In winter, quick access to a veterinarian and well-organized treatment are essential. This is where VetFile can help — a platform that connects farmers and animal owners with veterinarians:

• Find a veterinarian in your area. The search engine on vetfile.pl helps you find a veterinarian specializing in cattle and check the services they offer.
• Remote consultation. If you are unsure whether symptoms require an in-person visit, you can use an online consultation via chat, phone call, or video call.
• Convenient appointment scheduling. Veterinarians using VetFile can provide an online booking calendar and send SMS and email reminders, for example about vaccination appointments.
• Organized herd records. The system allows veterinarians to create and manage a herd and maintain the Livestock Treatment Book, with the option to print it, ensuring that the treatment history is complete and readily available.
• Access in the field. The program operates in the cloud, so veterinarians can access herd data during farm visits using a phone or tablet with an internet connection.

A well-prepared barn, careful observation of calves, and preventive care planned together with a veterinarian are the best ways to get through winter without losses in the herd. The earlier you take care of ventilation, bedding, and vaccinations, the fewer surprises you will face during the coldest months.
