  • Improved animal welfare

Earn at least USD 3000 extra per batch with the award-winning DOL 53 Ammonia Sensor for livestock

Studies* have shown that high ammonia concentrations in broiler production lead to higher FCR, lower weight gain and poorer welfare. All significantly affect financial returns. Even low ammonia concentrations up to 25 parts per million can reduce bird weight at 28 days by 2-7%, while 50 parts per million has been shown to reduce bird weight by 16-19%.

Early action supports broiler welfare and performance, making continuous ammonia monitoring highly useful. Research in this field** shows that elevated concentrations can reduce profits by USD 3000 or more per batch in a house with 25 000 broilers.

DOL 53 is an ammonia sensor specially designed for continuous measurement of ammonia (NH3) concentrations in livestock houses. It accurately measures both low and high ammonia concentrations and has minimal cross-sensitivity to other gases.

Award-winning ammonia sensor

In 2016, DOL 53 received a silver medal in the Innovation Award at EuroTier, the world's leading livestock exhibition. The competition is judged by an independent international committee of recognized consultants, scientists and practitioners appointed by DLG (German Agricultural Society).

Scientists from the Department of Poultry Science at the University of Georgia's College of Agricultural and Environmental Sciences completed a total of four trials. Their final report confirms that “The DOL 53 ammonia sensor performed extremely well during initial field testing in a poultry house”.
