The RQR-GDR Repro partnership grant offered to Drs. Jocelyn Dubuc (UdeM) and Nicole Picard-Hagen (École Nationale Vétérinaire de Toulouse) by the RQR in 2020 has enabled the implementation of research work on “the identification of prepartum blood metabolite concentrations associated with the subsequent occurrence of placental retention and endometritis during the postpartum period in dairy cows” and the production of the following 2 publications (with more to come):

1. Herd-level associations between the proportion of elevated prepartum nonesterified fatty acid concentrations and postpartum diseases, reproduction, or culling on dairy farms. J. Denis-Robichaud, I. Nicola, H. Chupin, J.-P. Roy, S. Buczinski, V. Fauteux, N. Picard-Hagen, R. Cue, and J. Dubuc: https://www.sciencedirect.com/science/article/pii/S2666910224000085
2. Association between prepartum nonesterified fatty acid serum concentrations and postpartum diseases in dairy cows. I. Nicola, H. Chupin, J.-P. Roy, S. Buczinski, V. Fauteux, N. Picard-Hagen, R. Cue, and J. Dubuc: https://www.sciencedirect.com/science/article/pii/S0022030222005525

Congratulations to all the authors and collaborators on this project!

The meeting of dairy producers of the bovine ambulatory clinic, Faculty of Veterinary Medicine, UdeM was held on January 31, 2024 in Saint-Hyacinthe. RQR was one of the event’s sponsors. Several RQR members gave lectures:

• Christian Vigneault (Collaborator, BOVITEQ) et al. on assisted reproduction in 2023
• Véronique Ouellet (ULaval) on heat stress in dairy cows in Quebec
• Marianne Villetaz-Robichaud (UdeM) on cow comfort in the era of the new code of practice
• Annie Fréchette (DSAHR) on new health management software and services
• Véronique Fauteux et al (CHUV Bovin, UdeM) on raising awareness of carbon neutrality on dairy farms
• Mauricio Badillo et al (CHUV Bovin, UdeM) on new developments in pharmacy

Congratulations for this knowledge transfer activity. See souvenirs below.

Dr. Nicolas Gevry (UdeS) and Dr. Bruce Murphy (UdeM) obtained a grant of  $937 125 from CIHR for their project titled ” The fertility clock: Regulation of the maintenance and depletion of the ovarian reserve”. Their study will focus on the mechanisms of SF-1 activation of the primordial follicles and its role in preventing ovarian aging and depletion of the ovarian reserve.

Congratulations!

The “Producers meeting” was held on February 1, 2023 at the St-Hyacinthe Convention Center. A total of 120 people including 100 dairy producers were present. Dr. Jocelyn Dubuc presented research content in reproduction applicable to producers. The meeting was a great success for knowledge mobilization.

The RQR, Op+Lait and CHUV supported the event.

Congratulations!
