Review: Exploring correctness, usefulness, and feasibility of potential physiological operational welfare indicators for farmed insects to establish research priorities

M.G. Johnson, M. Barrett

Published in 2025

Study evaluating the correctness, usefulness and feasibility of physiological and somatic indicators currently used to assess welfare in vertebrates for the assessment of insect welfare, taking into account their particular biological characteristics. It proposes a priority list of indicators for validation in insect welfare research, allowing the welfare of farmed insects to be assessed in a reliable, useful and feasible  way.

Measuring minds: Understanding the mental states of dairy cattle in different management conditions

Heather W. Neave

Published in 2025

Review of a symposium on the  assessment of how the mental states of dairy cattle (positive emotions and cognitive functions in particular) are affected by management practices. It highlights the behavioral, physiological and cognitive indicators available and the potential of emerging automated on-farm monitoring technologies.

Characterisation of facial expressions and behaviours of horses in response to positive and negative emotional anticipation using network analysis

Romane Phelipon, Léa Bertrand, Plotine Jardat, Fabrice Reigner, Kate Lewis, Jérôme Micheletta, Léa Lansade

Published in 2025

Study using network analysis to identify specific behaviors and facial expressions in horses based on their anticipation of a positive or negative experience. These indicators can be used to better assess the emotional state and welfare of equines.

Healthy cows, happy farmers? Exploring the dynamics of mastitis and farmer well-being

Lind Nina, Hansson Helena, Emanuelson Ulf, Lagerkvist Carl-Johan

Published in 2025

Study showing that cow health influences the psychological welfare of dairy farmers. This connection is reinforced by the farmers' perceptions of the disease (in this case mastitis) and their sense of control over it.

Observational study: effect of varying transport durations and feed withdrawal on the physiological status and health of dairy calves

van Dijk, Luca L., Siegmann, Susanne, Field, Niamh L., Sugrue, Katie, van Reenen, Cornelis G., Bokkers, Eddie A. M., Conneely, Muireann, Sayers, Gearoid

Published in 2025

Study evaluating the impact of transport and fasting on the physiology and health of unweaned calves. The results show that the physiological changes observed on arrival were related more closely to the duration of feed deprivation rather than that of transport, although muscle fatigue was more marked in calves that had travelled the longest.

The Interface of Caretaker and Animal Well-being As a Critical Component of Sustainability

Edwards-Callaway, L. N. & Sullivan, P. A.

Published in 2024

Study exploring welfare, both human and animal, as one of the pillars of sustainability in the farmed animal industry. This pillar is often neglected in favor of the environmental and economic pillars.

Effects of space allowance on behaviour during lairage, stress physiology, skin lesion scores, and meat quality of market pigs transported in an actively ventilated vehicle in the winter

Vanessa Pasquale, Luigi Faucitano, Nicolas Devillers, Sabine Conte, Renée Bergeron

Published in 2024

Study evaluating the impact of winter transport on pig pwelfare and meat quality. The results show that the location of pigs in the vehicle (upper vs. lower deck) has a greater effect than the space available, influencing their behavior, meat quality and certain blood parameters. Pigs transported in the upper deck are exposed to colder temperatures, affecting muscle brightness and behavior.

Impact of musical rhythm on blood, physiological and welfare parameters in stabled horses

Fernanda Yumi Ueno de Oliveira, Agnês Markiy Odakura, Maria Fernanda de Castro Burbarelli, Caio César dos Ouros, Ibiara Correia de Lima Almeida Paz, Jaqueline Murbach Braz, Rodrigo Garófallo Garcia & Fabiana Ribeiro Caldara

Published in 2024

Study evaluating the effect of two styles of classical music (slow and moderate tempo) on the welfare of horses during social isolation. Both music styles increased serotonin levels, but the moderate tempo music also influenced certain blood indicators, such as calcium and hemoglobin levels. These results show that music can contribute to the welfare of horses in the stable.
