Swine it # 55: How to optimize tunnel ventilation in pig barns - Dr Brett Ramirez
"When managing tunnel ventilation, we need to make sure we have wind. If there's no wind, we're effectively not providing any cooling, and the big driver of that is our fans. With that comes making sure our fans are performing optimally: belts are tight, functioning, clean, cones, and shutters are on. A lot of times, shutters can get dirty over winter, and if they don't get cleaned off by the time summer rolls around and pays to keep those shutters clean because they can knock down airflow over 15%"
