Adjusting Minimum Ventilation Using Relative Humidity Meters

Most broiler producers understand that ammonia levels above 30 ppm can have an adverse effect upon broiler health and performance. The problem is knowing exactly what 30 ppm smells like. To further complicate matters, a person's ability to determine the presence of ammonia decreases over the years. So even if someone knows what 30 ppm ammonia smells like today, a couple of years down the road 50 ppm ammonia may smell like what 25 ppm smelled like a few years ago.
