Ventilating A Retrofitted Stanchion Barn For Calves

By Jessica Getschel, B.S.

There’s nothing more picturesque than a dairy farm with a big red barn on a cobblestone foundation. Many of these barns, referred to as stanchion, tiestall or bank barns, were built decades ago and tell stories of families who have been dairy farming for generations.

Over the years, many farmers have moved out of these older barns and into modern freestall barns for a variety of reasons: expanding herd size, new cow comfort recommendations or a new milking system, to name a few. This departure leaves a vacant building prized for its emotional value to the farm.

Understanding The Principles Of Calf Barn Ventilation

By Jessica Getschel, B.S.

Understanding the basic principles of calf barn ventilation is essential in evaluating the many different ventilation options available today. There is no single ventilation system that will work for every situation because each calf barn is unique in its structure and layout.

The goal of a properly designed ventilation system should be to provide clean, fresh air at all times for healthy calf development. Ventilation is responsible for removing accumulated heat, moisture, air borne pathogens and noxious gases from the animal’s environment. These factors support the rationale behind ventilating year round, as moisture, pathogens and gases are constantly being released and a buildup of these factors leads to respiratory stress in calves.

Key Design Features To Consider Before Building A New Calf Barn

By Jessica Getschel, B.S.

Proper barn planning saves time and money. For every decision, it is important to understand its associated ramifications. In calf barns, housing style and pen configuration decisions impact ventilation options, which in turn affects the overall success of the barn. Before building a calf barn, think about the ventilation requirements for every season. Allocate at least 10 percent of the overall building cost for the purchase of a well thought out ventilation system and ask these three questions as you consider your ventilation options:

  • Will the system deliver a consistent source of fresh air into the barn during all seasons?
  • Will the system effectively control the airspeed at calf level?
  • Can the ventilation system rapidly adjust to the changing weather conditions of spring and fall when there are warm days and cool nights?

By Ryan Leiterman, D.V.M.

Cold temperatures are here and winter is quickly approaching. As the temperatures drop, calf barns are closed up and the ventilation rates are turned down. As an industry we do this reflexively, but is it what’s best for the calves?

Studies show that pre-weaned calves raised in hutches have lower pneumonia rates when compared to calves raised in barns. Even calves raised in calf barns equipped with modern ventilation systems can experience increased respiratory disease rates when compared to their hutch-raised counterparts.

What are the benefits of a pre-engineered positive pressure tube system?

Crystal Creek® is now handling pre-engineered tube systems. These duct systems have reduced set up and production time, lower material waste and use bulk shipments for lower freight costs; making the ducts less expensive when compared to a customized duct. Pre-engineered duct systems do not require a ventilation designer to engineer the system, further reducing costs.

Come Meet Dr. Leiterman

Discuss your calf barn ventilation needs at Wisconsin Farm Technology Days August 25-27, 2015 in Sun Prairie and at World Dairy Expo Sept 29-Oct 3, 2015 in Madison, WI.

 Dr. Leiterman is a dairy veterinarian experienced in calf barn ventilation design and analysis. He holds degrees in both Agricultural Engineering and Veterinary Medicine.

 During his time in practice, Dr. Leiterman has experienced first-hand how a properly designed ventilation system can improve calf health and calf raising profitability.  Producers are encouraged to consider all factors that will improve the quality of the air the calves will breathe. As a calf barn ventilation engineer and a veterinarian, Dr. Leiterman has designed over 100 calf barns across the United States. Seeing different types of operations has given him the opportunity to learn various calf barn construction techniques that can improve air quality and reduce construction costs.
