Studies* have shown that high ammonia concentration in broiler production results in a higher FCR, lower gain, and poorer welfare. All of which have a major impact on the financial yield of the production. In fact, ammonia concentrations as low as 25 ppm can reduce bird weights at 28 days of age by 2-7% while 50 ppm ammonia has been shown to reduce bird weights from 16-19%.
Early action benefits the welfare and productivity of the broilers, which is why it is highly beneficial to continuously monitor ammonia levels.
Research in this area** shows that an increased concentration can cut profits by $3,000 or more per batch in a livestock house with 25,000 broilers.
DOL 53 is an ammonia sensor specifically designed for continuous measurement of ammonia (NH3) concentration in livestock houses. The sensor can accurately measure the level of ammonia in both low and high concentration and has a negligible cross sensitivity to other gasses.
Award winning ammonia sensor
In 2016, DOL 53 won a silver medal at the Innovation Award at EuroTier, which is the world’s leading trade fair for animal production. The competition is judged by an independent international committee of recognized consultants, scientists, and practitioners appointed by the DLG (German Agricultural Society).
Scientists from The Department of Poultry Science at the College of Agricultural and Environmental Sciences of the University of Georgia completed a total of four trials. Their final report confirms that “the DOL 53 ammonia sensor performed extremely well in initial poultry house field trials”.*
