The application of multi-omics approaches to the tracking and assessment of the gastrointestinal microbiome for rumen, GIT and animal health. To evaluate the impact of feed, feed-management and feed additives on AMR, host-microbe crosstalk, immunity and the mitigation of production related diseases.
Current research and/or projects
My current projects are based on understanding the feed-microbiome-host interactions, specifically with regard to developing knowledge in the area of animal and rumen health. The diverse approaches used in these studies make use of the ever increasing molecular and bioinformatic tools available and have applied knowledge and techniques from human medical research to improve the health and sustainability of animal agriculture.
Research and/or project statements
- Role of the gastrointestinal microbiome in animal immunity and productivity
- Evaluate feed management in transition on metabolic disorders, rumen dysbiosis and immunity
- Determining the impact of the energy to protien ratio in forages on the adherent ruminal microbes and their metabolism
- Impact of feed additives on the host-microbiome crosstalk
