Published in 2023

Scientific paper to examine the effects of the complete elimination of painful procedures and of reducing weaning stressors in the living conditions of piglets on a commercial farm. This form of management resulted in improved innate immunity at weaning, fewer and less severe body lesions but more tail lesions than in the control pigs.

Innovation across 13 ungulate species: problem solvers are less integrated in the social group and less neophobic

Alvaro L. Caicoya, Alina Schaffer, Ruben Holland, Lorenzo von Fersen, Montserrat Colell, Federica Amici

Published in 2023

Scientific paper on the problem-solving abilities of 13 ungulate species. Using a foraging task, it tests whether individual factors (neophobia, social integration, sex, age, status) and socio-ecological factors (dietary range, fission-fusion dynamics, domestication, group size) are predictors of participation and performance in the task.

Development of a data-driven method for assessing health and welfare in the most common livestock species in Switzerland: The Smart Animal Health project

Beat Thomann, Hanno Würbel, Tahibault Kuntzer, Christina Umstätter, Beat Wechsler, Mireille Meylan, Gertraud Schüpbach-Regula

Published in 2023

Article describing how a method was developed to assess health and welfare on individual Swiss livestock farms using information from agricultural databases and supervised machine learning. This method made it possible to score the animal health and welfar management performance of farms in a way comparable to on-farm assessment by trained staff.

Published in 2023

EFSA opinion identifying fifteen highly relevant negative welfare consequences, the most common being respiratory disorders, inability to engage in exploratory or foraging behavior, gastroenteric disorders and group stress. It recommends a space provision of at least 3m2 per calf, keeping the calf with its mother for a minimum of 24 hours, after which calves should be kept in stable groups and soft bedding should be provided.

Advancing the quantitative characterization of farm animal welfare

Harriet Bartlett, Andrew Balmford, Mark A. Holmes, James L. N. Wood

Published in 2023

Paper developing welfare indicators for use in life cycle assessment (LCA) and different ways of aggregating them, then testing them on British pig farms. It shows that farms in the same LCA class have the same types of quality labels, and that the details of the way in which LCA welfare measures are established have little impact on the classification of farms based on their welfare levels.

Visual perception of emotion cues in dogs: a critical review of methodologies

Catia Correia-Caeiro, Kun Guo, Daniel S. Mills

Published in 2023

Scientific review revealing that research on the visual perception of emotions in dogs focuses on facial emotional cues, often ignoring whole-body information, and pointing to the interpretive errors that can arise as the result of poor study design and incorporation of biases such as anthropomorphism. It suggests that new technologies nevertheless offer a way to resolve data collection issues, offering useful perspectives in this area of study.

Published in 2023

EFSA opinion identifying the most important factors impacting on the welfare of laying hens: bone lesions, group stress, inability to avoid unwanted sexual behavior, inability to engage in comfort behavior, inability to engage in exploratory or foraging behavior, isolation stress, predation stress, resting problems, movement restriction, skin disorders, soft tissue lesions and integument lesions. It proposes animal-based measures to assess them, and sets out the risks related to different farming systems. Measures to prevent risks and mitigate welfare consequences are proposed. Recommendations are made to address specific welfare issues for laying hens.
