• Welfare assessment of racehorses provides a baseline for continued monitoring · 2026

  Résumé de la publication : Racehorse welfare continues to be a focus of stakeholders both within and outside of the industry, and there is a need for evidence‐based animal welfare data. Objectives To gather data on racehorse welfare through a combination of animal‐based observations and information about…

• Method: Modelling resource acquisition and allocation – extension and calibration of a cow model to a sheep · 2026

  Résumé de la publication : Simulation models are suitable to investigate how complex systems respond to changes. This is of particular interest regarding animal feed efficiency as this trait must be evaluated throughout the entire lifetime and thus is affected by trade-offs between physiological functions. The aim…

• The composition of the lactation diet but not the previous rearing feeding level affects the response to an oral drench of propylene glycol in primiparous lactating dairy goats · 2026

  Résumé de la publication : The aim of this experiment was to study if different growth trajectories during rearing influence adaptive capacity to metabolic challenges during lactation. Sixteen female Saanen goats were selected at weaning and given either a high growth trajectory diet (High GT, n=8) or…

• Lactation persistency of dairy cows fed low metabolizable protein diets with two different starch contents and degradability levels crossed with rumen-protected amino acid supplies · 2026

  Résumé de la publication : Reducing the CP and MP content of diets allows to improve dairy cow nitrogen and MP efficiencies. However, when CP ( 13-14%) and MP (95 g/kg DM of Protein Digestible in the Intestine, PDI) contents are reduced, DMI, milk yield and milk…

• BeefPOP: a physiologically based toxicokinetic model describing the fate of polychlorinated biphenyls in growing beef cattle · 2026

  Résumé de la publication : Polychlorinated biphenyls (PCBs) are persistent organic pollutants that bioaccumulate in livestock and threaten food safety. Understanding PCB kinetics in farm animals is essential for effective risk management. This study introduces BeefPOP, a mechanistic model that couples fugacity and physiologically based toxicokinetic concepts…
