L Series Pole Barn Kits
L Series pole barn kits provide more square footage for shorter building sites without the requirement of expensive clear span trusses required when widening buildings to gain floor space. A lean to addition works too but this configuration provides plenty of eave height throughout the building compared to a shed addition.
These configurations can be relocated to the center of the building, eave height can be changed, and width and length adjusted as necessary to meet your requirements.

L shaped barns are very common on farms. The barn is often situated
to form a sheltered yard type arrangement. The main wing should be used to serve the animals, with the ell being used for feed
ing, or storage space.
Introducing fresh air into the barn is critical for comfort of animals. Controlled ventilation allows fresh air in while maintaining a comfortable environment for the animals living there.
Ventilation keeps odor down, removes carbon dioxide, and evaporates moisture. A single dairy cow breathes more than 200 pounds of air in a 24 hour period. Since the blood is purified when it passes through the lungs, this is critical to keeping stock healthy. Not only that, excessive carbon dioxide reduces animal production, causes sluggish behavior, and is generally something to be avoided.
An average cow produces 11 1/2 pounds of water per day via exhaling, through the pores of the skin, and out the kidneys. A badly ventilated barn will seem steamy on cold mornings. Damp barns lead to sickness like pneumonia. It is possible to calculate the amount of air required for animals. A horse requires 71 cubic feet of air per minute, a cow 59 cu ft, a pig 23 cu ft, and sheep require 15 cu ft.
Agricultural Ventilation Systems
Exhaust type ventilation systems provide a partial vacuum within a building to induce the introduction of air into the structure. These fans should have sealed motors and bearings with heavy duty blades to stand up to a dusty corrosive environment. The Air Movement & Control Association tests and rates fans. They provide ratings that can be relied upon to determine air delivery volumes. Remember that air temperature impacts air volume delivery.
This table depicts the estimatated air delivery required for various farm animals to achieve optimum performance and health.
|Ventilation per animal Unit
(CU FT / MINUTE)
|Farm Animal||Desired Temp ° F||Winter Minimum||Winter Typical||Summer|
|Horse Per 1000 lbs||55||25||100||200|
|Beef Per 1000 lbs||55||15||100||200|
|Poultry Per Pound||55 - 60||.125||0.5||1|
|100 pound pig||60||5||20||48|
|Sow With Litter||60-80||20||20||210|
Some general guidelines for slot locations in buildings are:
• 30' Width or less use either a center ceiling slot or a slot along the outside of one wall.
• 30-48' Width use slots at the top of both outside eave walls.
• Greater than 48' wide use slots on both eave walls (top slots) and one or more center ceiling slots.
Just like humans, comfortable animals produce better!
