New colorimetric sensors indicating levels of airborne ammonia in animal facilities have been introduced on the market. LITMUS Ammonia Indicators (LAI) monitor average ammonia levels over 4 and 24 hour periods. Two years of collaborative R&D between LITMUS, animal growers, academic institutions and industry professionals resulted in the creation of the LAI.
Jack Lewis, President of LITMUS FQI, said, “A key issue in maintaining healthy animals is to quickly and accurately measure the average levels of ammonia in animal facilities. LAIs replace the very subjective practice of sniffing or using other devices which are expensive and inherently inaccurate.”
LAI requires no interpretation and allows operating adjustments to control ammonia levels. Nicole Klosterman, Bio-Mos/De-Odorase Brand Manager at Alltech, Inc., said: “We use LAI, the first technology available that will measure ammonia levels based on a 24 hour average to prove that putting De-Odorase in the feed will lower standard ammonia levels.”
LAI is calibrated to target measurement thresholds of ammonia of 25 parts per million (ppm) and 50 ppm. Animals grown in these environments are larger, healthier and a better grade of animal with better feed conversion.
