Workshops

Workshops

On Tuesday, 4 September, three workshops will be organized on the following topics:

› Workshop A, Research priorities for assessing and mitigating Green House Gases emissions from herbivores

     10:40 - 12:10 in the Lecture Hall

› Workshop B, Evaluation of animal performances and products quality: a current state of methods and indicators

     10:40 - 12:10 in the Volcano room

› Workshop C, Agroeocology and herbivores farming systems: current state and perspectives

     10:40 - 12:10 in the Lake room

Each workshop will be introduced by offered papers selected from the pool of submitted one-page abstracts in the relevant topics.

Workshop A, Research priorities for assessing and mitigating Green House Gases emissions from herbivores

This workshop will be coordinated by Diego Morgavi (INRA, France)

The topic will be introduced by short presentations updating current international initiatives for mitigating GHG and with a state-of-the-art summary of the tools and techniques available to measure and estimate emissions.  Two research works offered to the 10th ISNH will be presented as examples:

  • Including bioactive legumes in grass-based silage to improve performances and reduce methane emissions in sheep. Vincent Niderkorn (INRA, France)
  • Effect of basal diet on the methane mitigation effect from dietary fat supplementation. Pablo Alvarez (Univ. Melbourne, Australia)

The workshop will then be followed by exchanges with the audience on the role and priorities of research for decreasing the environmental footprint of ruminant production. 

Workshop B, Evaluation of animal performances and products quality: a current state of methods and indicators

The workshop coordinated by Brigitte Picard  and Bruno Martin (INRA,  France) will be introduced by two communications of 10 minutes each :

  • Saliva samples as non-invasive proxies to determine the rumen 18-carbon fatty acid composition of dairy cows suffering or not from subacute ruminal acidosis. Lore Dewanckele (Gent Univerity, Belgium)
  • Exploring the effects of dietary lipid content and digestibility on lipophilic contaminants transfer from feed to milk in dairy cow: insights from a physiologically-based toxicokinetic modelling approach. Sylvain Lerch (Université de Lorraine, Vandoeuvre-lès-Nancy, France)

                                                                                        
The exchanges will then focus on new approaches and techniques for the study of this thematic in order to share experiences.

 

Workshop C, Agroeocology and herbivores farming systems: current state and perspectives

The ultimate goal of this workshop coordinated by Eliel Gonzalez-Garcia, Maryline Boval and Bertrand Dumont (INRA, France) is to share a rich discussion around the role of agroecology in promoting sustainable herbivores farming system for the future. After some dissertations related to the topic, presented in the introductive session by recognized speakers, the workshop will start by a short introduction:

  • Agroecology and ecosystem services: how to progress from concepts to operational? by Maryline Boval (INRA, AgroParis Tech, Paris, France)

Two illustrative case studies from contrasted edaphoclimatic (i.e. temperate and tropics) and systems (i.e. grassland and silvopastoral) conditions will then be presented:

  • How grassland management impacts legume species and their potential ecosystem services delivery? by Morgane Campion (Walloon Agricultural Research Center, Gembloux, Belgium)
  • Silvopastoral systems with wild sunflower shrubs (Tithonia diversifolia) as alternative for competitive and sustainable milk production in high tropic: experience in Colombia by Joaquin Angulo & Liliana Mahecha (Univ. Antoquia, Medellin, Colombia)

Further exchanges with the audience must help to answer key questions such as i) How to apply the principles of agroecology in herbivores farming systems? ii) What makes the difference between herbivorous species and across latitudes? iii) How to conciliate productivity and ecosystem services in those systems, based on an agroecological approach? iv) Which benefits from agroecology and ecosystem services for the farmer and the society?
