Electronic Controls For Swine Buildings, Douglas G. Overhults, R. S. Gates
Agricultural Engineering Extension Updates
This fact sheet discusses the use of electronic controllers to maintain the environment within swine barns. There are some special considerations when using electronic controllers to replace traditional control systems. Three main items are addressed in this fact sheet: 1) the selection of a controller, 2) installation considerations, and 3) protection against controller failure.

Full-Wall Ventilation For Dairy Free Stall Barns, Larry M. Turner, John P. Chastain
Agricultural Engineering Extension Updates
Heat stress should be a greater concern than winter cold for dairymen in Kentucky. Heat stress can cause drops in milk production and breeding efficiency, which result in lower profits for the dairyman. The use of an open sidewall free stall barn can help relieve heat stress by allowing improved ventilation of the barn in summer. The benefits of full-wall ventilation include both improved air movement and some potential increase in evaporative cooling. The increased airflow through the barn increases convective cooling of the cows and carries off a greater amount of excess heat and moisture than conventional barns with …
