Published in 2023

EFSA opinion that identifies 19 major welfare consequences for broilers, animal-based measures to assess them, risks related to different farming systems and animal-based measures to assess them. Measures to prevent risks and mitigate welfare consequences are proposed. Recommendations are made to address specific welfare issues for broilers. Indicators for monitoring the welfare of broilers at slaughter are proposed.

Cleaner fish recognize self in a mirror via self-face recognition like humans

Masanori Kohda, Redouan Bshary, Naoki Kubo, Shumpei Sogawa

Published in 2023

Scientific article showing that the cleaner fish (Labroides dimidiatus) is able to recognize itself in a mirror and in a photograph, and to distinguish itself from its relatives, which proves that it has the necessary cognitive capacities to build a mental image of itself.

Outside enclosure and additional enrichment for dairy goats

Knut Egil Bøe, Rebecca Ehrlenbruch, Inger Lise Andersen

Published in 2012

A scientific paper investigating the effects of access to an outdoor pen and environmental enrichment on the activity pattern and social behavior of Norwegian dairy goats kept on slatted floors with limited space. It shows that the goats prefer to use the outdoor pen when they are active, and view branches as an attractive enrichment.

Resting pattern and social interactions in goats—The impact of size and organization of lying space

Inger Lise Andersen, Knut Egil Bøe

Published in 2007

Scientific paper showing that the time Norwegian dairy goats spent resting and their resting habits depended more on the size than the lay-out of the lying space, while social interactions depended more on the lay-out than on the size of the lying space.

Lauri Torgerson-White, Walter Sánchez-Suárez

Published in 2022

Scientific review on the current status of welfare assessment methods in aquaculture, comparing them with those for terrestrial animals, and offering recommendations for future research that would allow account to be taken of fish welfare at the level of the individual.

Glucocorticoids in relation to behavior, morphology, and physiology as proxy indicators for the assessment of animal welfare. A systematic mapping review

Inga Tiemann, Lisa B. Fijn, Marc Bagaria, Esther M. A. Langen, F. Josef van der Staa3, Saskia S. Arndt, Cathalijn Leenaars, Vivian C. Goerlich

Published in 2023

A systematic review of the literature to determine whether glucocorticoid levels are a relevant indicator of animal welfare. It found that interventions that supposedly affect glucocorticoid levels do not always do so, and when they do, the changes in level are not always accompanied by changes in the associated welfare endpoints of behavior, morphology and physiology.

Effect of Heat Stress on the Behavior of Lactating Cows Housed in Compost Barns: A Systematic Review

Authors: Karen Dal' Magro Frigeri, Matheus Deniz, Flávio Alves Damasceno, Matteo Barbari, Piotr Herbut, Frederico Márcio Corrêa Vieira

Published in 2023

Scientific review of the effect of heat stress on the behavior of lactating cows housed in composted bedding barns. It revealed that the most commonly used indicator of thermal comfort is the temperature and humidity index; that thermal stress increases drinking, moving, agonistic behaviors and dyspnea, and decreases feeding behaviors and lying time.

Domestic hens succeed at serial reversal learning and perceptual concept generalization using a new automated touchscreen device

Rachel Degrande, Fabien Cornilleau, Léa Lansade, Plotine Jardat, Violaine Colson, Ludovic Calandreau

Published in 2022

Scientific paper testing the effectiveness of an automated device for performing cognitive tests in domestic fowl: a simple test, a serial instruction reversal learning task; and a more complex test, and a delayed sample matching task. The results reveal the behavioral flexibility and conceptual understanding of domesticated hens. They also demonstrate the value of using automated devices to improve our knowledge of farm animal cognition.
