Can AI imaging technology be used for monitoring specific behaviours in broiler flocks (2022)
Presentation / Conference Contribution
Demmers, T. (2022). Can AI imaging technology be used for monitoring specific behaviours in broiler flocks.

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.

Associations between behaviour and health outcomes in conventional and slow-growing breeds of broiler chicken (2021)
Journal Article
Abeyesinghe, S., Abeyesinghe, S., Chancellor, N., Hernandez Moore, D., Chang, Y., Pearce, J., …Nicol, C. (2021). Associations between behaviour and health outcomes in conventional and slow-growing breeds of broiler chicken. animal, 15(7), Article 100261. https://doi.org/10.1016/j.animal.2021.100261

Broiler chickens are prone to a range of complex health and welfare issues. To support informed selection of welfare traits whilst minimising impact on production efficiency and to address a major gap in understanding, we systematically explored asso...

Neural predictive control of broiler chicken and pig growth (2018)
Journal Article
Demmers, T. G. M., Cao, Y., Gauss, S., Lowe, J. C., Parsons, D. J., & Wathes, C. M. (2018). Neural predictive control of broiler chicken and pig growth. Biosystems Engineering, 173, 134-142. https://doi.org/10.1016/j.biosystemseng.2018.06.022

Active control of the growth of broiler chickens and pigs has potential benefits for farmers in terms of improved production efficiency, as well as for animal welfare in terms of improved leg health in broiler chickens. In this work, a differential r... Read More about Neural predictive control of broiler chicken and pig growth.

Exposure to environmental stressors result in increased viral load and further reduction of production parameters in pigs experimentally infected with PCV2b (2015)
Journal Article
Patterson, R., Nevel, M., Diaz, A. V., Martineau, H. M., Demmers, T. G. M., Browne, C., …Werling, D. (2015). Exposure to environmental stressors result in increased viral load and further reduction of production parameters in pigs experimentally infected with PCV2b. Veterinary Microbiology, 177(3-4), 261-269. https://doi.org/10.1016/j.vetmic.2015.03.010

Porcine circovirus type 2 (PCV2) has been identified as the essential, but not sole, underlying infectious component for PCV-associated diseases (PCVAD). Several co-factors have been suggested to convert an infection with PCV2 into the clinical signs...

Effect of transportation duration of 1-day-old chicks on postplacement production performances and pododermatitis of broilers up to slaughter age (2013)
Journal Article
Bergoug, H., Guinebretiere, M., Tong, Q., Roulston, N., Romanini, C. E. B., Exadaktylos, V., …Michel, V. (2013). Effect of transportation duration of 1-day-old chicks on postplacement production performances and pododermatitis of broilers up to slaughter age. Poultry Science, 92(12), 3300-3309. https://doi.org/10.3382/ps.2013-03118

This experiment studied the effect of transportation duration of 1-d-old chicks on dehydration, mortality, production performance, and pododermatitis during the growout period. Eggs from the same breeder flock (Ross PM3) were collected at 35, 45, and...

Development and application of a novel environmental preference chamber for assessing responses of laboratory mice to atmospheric ammonia
Journal Article
Green, A. R., Wathes, C. M., Demmers, T. G. M., Clark, J. M., & Xin, H. W. Development and application of a novel environmental preference chamber for assessing responses of laboratory mice to atmospheric ammonia

A novel environmental preference chamber (EPC) was developed and used to assess responses of laboratory mice to atmospheric ammonia. The EPC features 1) a test chamber with 4 individually ventilated, mutually accessible compartments; b) automated tra...
