Z. Parr-Cortes, C. T. Müller, L. Talas, M. Mendl, C. Guest, N. J. Rooney

Published in 2024

Scientific article confirming that dogs can discriminate between human odors emitted during positive or negative emotions with no other cues. The results also show that olfactory signals of human stress affect dogs' behaviors when approaching a bowl of food placed in an ambiguous location and may affect their learning.

Behaviour and welfare assessment of autochthonous slow-growing rabbits: The role of housing systems

Laura Ozella, Stefano Sartore, Elisabetta Macchi, Isabella Manenti, Silvia Mioletti, Barbara Miniscalco, Riccardo Crosetto, Patrizia Ponzio, Edoardo Fiorilla, Cecilia Mugnai

Published in 2024

Scientific article evaluating the effect of three housing systems (traditional single cages, group farming and a mixed system) on the welfare of slow-growing rabbits. Group-housed rabbits exhibited a wider range of behaviors, but were also associated with higher levels of salivary and hair corticosterone indicating stress. Younger rabbits were more active while mature rabbits displayed more agonistic behaviors.

Evaluation of candidate data-based welfare indicators for calves in Switzerland

Sibylle Zwygart, Barbara Lutz, Beat Thomann, Dimitri Stucki, Mireille Meylan, Jens Becker

Published in 2024

Article showing that the four principles of Welfare Quality that indicate good animal welfare, namely "good feed", "good housing", "good health" and "appropriate behavior", are not reflected in routinely available data on veal calf farms in Switzerland, even though data for health status assessment is available. If animal welfare is to be inferred from routine data, there is a need to adapt data collection strategies and animal identification methods.

Family pigs' and dogs' reactions to human emotional vocalizations:a citizen science study

Fanni Lehoczki, Paula Pérez Fraga, Attila Andics

Published in 2024

Scientific article on a study testing whether the emotional contagion provoked in dogs by human sounds of distress is the result of their selection for cooperation with humans or is rooted in the universal signals of emotion. The authors compared the reactions of dogs and pigs to recordings of human crying and humming. Dogs became agitated when listening to crying, which the authors interpret as emotional contagion, while pigs were stressed by humming, which the authors interpret as neophobia (fear of the new).
