GplusE at EAAP Annual Meeting 2016

Why is an easily-measurable phenotypes that can supplement or correlate with and replace or improve traditional phenotypes needed? The preferred matrix in which to measure new phenotypes is milk, as it is more easily accessible than blood and allows low-cost, automated repeat sampling with potential for “in-line” sampling and analytical technologies. Genotype and Environment (GplusE) is five year project funded by the European Union has begun work in this area. The end result of GplusE will be a comprehensive, integrated identification of genomic – phenotypic associations relevant to dairy production across Europe.

In the GplusE project, milk data will be collected in a two-step approach: 1) verification of theoretically or less well documented new biomarkers and (2) collection of a large and broad-encompassing dataset covering all relevant biomarkers across a range of herds with differing genotypes management conditions. Presently the verification step has been completed with three novel phenotypes – glycans, metabolites and MIR spectra.

logo_EAAPA joint session between the Cattle and Genetic Commissions and GplusE will discuss the significance of the current results to date and what this means in terms of scientific development and policy implications at the EAAP 2016 Annual Meeting in Belfast, UK in a session entitled: Novel milk-based phenotypes for use in breeding and management applications in dairy production. The session will take place on 30th August from 14:00 – 18:00.

Prof Mark Crowe (GplusE co-ordinator, University College Dublin, Ireland) and Prof. Georg Thaller (Kiel University) will co-chair the session. Prof Crowe will give a brief introduction to the session followed by 11 presentations including the following:

  • Andreia SANTORO (University College Dublin, Ireland) Potential for novel glycan measurements in milk as biomarker phenotypes for dairy traits
  • Amélie VANLIERDE (Walloon Agricultural Research Centre and University of Liège, Belgium) Potential of milk MIR spectra to develop new health phenotypes for dairy cows in the GplusE project
  • Klaus INGVARTSEN (Aarhus University, Denmark) Potential for novel metabolite measurements in milk as biomarker phenotypes for dairy traits
  • Clément GRELET (Walloon Agricultural Research Centre and University of Liège, Belgium) OptiMIR: Use of MIR spectra to predict multiple cow status as advisory tools for dairy farms
  • Geoff POLLOTT (Royal Veterinary College, UK) Novel milk phenotypes based on a biological model of lactation
