Fin de l’élimination des poussins mâles d’un jour : le choix du sexage in ovo

Sophie Rehault-Godbert, Marie Bourin, Joël Gautron, Maxime Quentin

Published in 2023

Scientific review that recaps the French decree banning the killing of male chicks from laying-hen lines, and sets out the three possible alternatives. Of these, in ovo sexing is the only route that is currently technically and economically viable, and this is presented in depth.

Review: Space allowance for growing pigs: Animal welfare, performance and on-farm practicality

K.L. Chidgey

Published in 2023

Scientific review of the scientific basis for the most common approaches to determining minimum space allowances for growing pigs. It examines the various factors that influence and interact with their spatial requirements. It stresses the need for further research replicating commercial conditions to ensure that recommendations deliver positive welfare outcomes in a way that is both practical and relevant.

Domestic dog lineages reveal genetic drivers of behavioral diversification

Emily V. Dutrow, James A. Serpell, Elaine A. Ostrander

Published in 2022

Scientific paper to identify genetic factors in canine behavior and understand the relationships between dog breeds and the behaviors that define them. Genetic analysis shows that the diversification of canine behavior pre-dates the creation of modern breeds and that canine genetic diversity is associated with the co-expression of neurodevelopmental genes.

Welfare issues and potential solutions for laying hens in free range and organic production systems: A review based on literature and interviews

Claire Bonnefous, Anne Collin, Laurence A. Guilloteau, Vanessa Guesdon, Christine Filliat, Sophie Réhault-Godbert, T. Bas Rodenburg, Frank A. M. Tuyttens, Laura Warin, Sanna Steenfeldt, Lisa Baldinger, Martina Re, Raffaella Ponzio, Anna Zuliani, Pietro Venezia, Minna Väre, Patricia Parrott, Keith Walley, Jarkko K. Niemi, Christine Leterrier

Published in 2022

Scientific review identifying an increased risk to free-range hens of microbial and parasitic infections, heat stress and predation. They do, however, have better bone quality and show less evidence of pecking behaviors. The review sets out existing preventive strategies and identifies missed opportunities to use genetics and prenatal and nutritional factors to prevent these welfare issues in free-range systems.
