Presentation / Conference Contribution
Demmers, T. (2022, August). Can AI imaging technology be used for monitoring specific behaviours in broiler flocks. Presented at 10th European Conference on Precision Livestock Farming (ECPLF22), University of Veterinary Medicine Vienna, Vienna

Commercial poultry production, e.g. optimum bird growth, requires an optimally controlled environment, which is currently based upon temperature, humidity, CO2 and air pressure, whilst water and feed consumption are also measured.
PLF systems exist... Read More about Can AI imaging technology be used for monitoring specific behaviours in broiler flocks.

Presentation / Conference Contribution
Demmers, T. (2022, August). 238 ECPLF Demmers 2022 Final Version After Review. Presented at 10th European Conference on Precision Livestock Farming, Veterinärmedizinische Universität Wien, Austria

The Chinese poultry industry continues to use cages for growing both broiler and layer chickens in most commercial facilities with no plans to ban their use in the immediate future. In contrast, cages have been banned and are being phased out in Euro... Read More about 238 ECPLF Demmers 2022 Final Version After Review.
