    Fate of amino acids from absorption to milk protein

    10/4/18 | 11:12 AM time | Leipziger Messe

    At ISRP 2019, Dr Hélène Lapierre, a research scientist at the Sherbrooke Research and Development Centre in Québec and part of Agriculture and Agri-Food Canada, will explore how protein and energy intake affect amino acids.

    Dr Lapierre joined AAFC in 1984 when she began her PhD, after which she did a post-doc at the Beltsville USDA Center. She has been working at the Sherbrooke Centre since and received two research fellowships from OECD to work at the Rowett Research Institute in the UK and at the INRA of Theix in France.

    Her research aims to improve the efficiency of nitrogen utilisation through a better knowledge of intermediary metabolism of dairy cows. To achieve this goal, Dr Lapierre has developed an integrated approach using multi-catheterised cows and stable isotopes to determine both the supply from the diet and the utilisation of nutrients. She has authored or co-authored more than 150 peer-reviewed papers, 250 scientific publications and extension papers and received invitations to present at scientific and extension meetings in North and South America, Europe, China and New-Zealand. The results of her research target a reduction in feed costs for dairy farmers and a reduction in nitrogen losses to the environment.

    At ISRP 2019, she will give a lecture on "The Fate of Amino Acids from Absorption to Milk Protein: Impact of Protein and Energy Supply".
