Developing new methodology for extracting precision phenotypes from on-farm technology: A systemic modelling approach using accelerometers to derive behavioural indicators for dairy cow health and feeding status.
My specific objectives are to:
- Develop generic, real-time methods for efficient filtration and extraction of the biological signal from accelerometer-based sensor technologies for feeding activity and locomotion in individual cows
- Create generic models that integrate information from diverse sensors to provide robust biological indicators and novel phenotypes for both nutritional status and health status
- Determine the utility of the above methods in detecting off-feed situations and lameness at an early stage
I am a biologist with special interest in animal behaviour and welfare. In 2007 I achieved my PhD in biomechanical gait analysis using pigs as subjects. During my scientific career (2002 to 2013 at Aarhus University, Denmark) my main achievements so far have been to partake in the development of a dairy cow energy balance model which has the potential to become an important on-farm tool for the management of individuals. Furthermore, through my research with objective gait analysis of quadrupeds, I know the effects of lameness on both the behaviour and gait of cows. Importantly, I possess extensive experience with several precision livestock farming technologies that can be employed in monitoring animals automatically at the individual level, such as force plates, pressure mats, videos, feeding stations etc. I seek to valorise the opportunities that arise from combining data technology and biology for precision phenotyping and thereby provide improved tools for better management and improved genetic selection strategies.
