Roll-Over type curtain systems can be described as poly curtains that cover the sidewall ventilation openings on a livestock housing building when closed. When ventilation air is needed for temperature control & fresh air supply, the curtain can be opened from the top downwards to provide some, or more, opening as needed to let air into & through the building.

The all new No-Main Curtain is the lowest maintenance curtain on the market and operates without the use of a main cable. The No-Main system is very popular with farmers with large sidewall openings and long barns. Curtain systems can be arranged in a number of different configurations, catering to a wide variety of building and ventilation setups.

The Weather Stop curtain system is designed to close in large doors and openings on open front barns, commodity buildings, storage sheds and pavilions  allowing some air movement.

With modern milking herds, cows are milked 2 to 4 times per day. The milking herd is moved into the holding area then into the milking parlour. These parlours are highly automated and able to milk 20 to 100 cows at one time. This is done with manpower and semi-automatic equipment or with robotic assist. Since the density of animals in both the holding area and then the parlour is so high it becomes paramount to have excellent ventilation.

Altra-Air Sailfin HVLS fans blanket a very large area with constantly moving air to create an expansive comfort zone. As a result, this large ceiling fan can create an evaporative cooling effect of 3 to 4 degrees Celsius throughout the facility.

Free stall barns are typically split into a separate dry cow barn and the main barn containing the milking herd. The milking herd moves freely from their resting pak along concrete alleys that are scraped or flushed (to remove manure) to the feed bunks. The milking cow is usually tagged to automatically identify her for feed rations and milk productivity. Cows eat freely from the feed bunks which contains a total mix ration (TMR). The herd will be scheduled to be milked 2 to 4 times daily in the milking parlour which will be accomplished manually with semi-automatic milking equipment or with robotic milkers.

Tie Stall barns are still preferred in many areas since it lends itself to more direct contact with each animal, better health care and less aggression between animals. Modern automation with pipeline milking, automatic takeoffs, scrapers and stable cleaners and automatic ration distribution mean labour can be reduced.
