Research and/or project statements
- Residual feed intake (RFI) and methane production in cattle, and the general improvement of efficiency and sustainability of beef production.
- Control of gene expression via dietary means (nutrigenomics).
- Different genetic potentials for individual responses to changes in diet (nutrigenetics).
- Permanent gene expression changes that can be programmed in the next generation due to nutrition and/or other factors affecting the parental generation (epigenetics).
By utilizing changes in gene expression due to diet and/or other treatments, we can tease out a clearer understanding of how biological systems function and then apply this knowledge to improve beef production.
