Burlap and buddies: the effects of social enrichment (preweaning mixing) and object enrichment (burlap) on piglet behavior and welfare in the postweaning environment

Ashlyn Scott, Arielle Le Heiget, Reyna Stefanson, Jamie Ahloy-Dallaire, Meagan King

Published in 2024

Scientific article demonstrating that early social enrichment encourages socialization with unfamiliar conspecifics during post-weaning, while object enrichment (burlap) allows pigs to divert their attention and limits aggressive behavior and the biting of conspecifics. Both types of enrichment can improve pig behavior and welfare after weaning.

Dairy farmers' preferences for immediate versus late calf separation

Albert Boaitey

Published in 2024

Analysis of a survey carried out in the US to gain an understanding of dairy calf farmers' perceptions of the practice of allowing prolonged contact between mother and calf. The survey concludes that the foster cow system was the preferred alternative to conventional early separation, followed by restricted suckling systems. The lowest-ranked alternative system was free contact between calf and mother.

Exploration of skin redness and immunoglobulin A as markers of the affective states of hens

Delphine Soulet, Anissa Jahoui, Rodrigo Guabiraba, Léa Lansade, Marie-Claire Blache, Benoît Piégu, Gaëlle Lefort, Vanaique Guillory, Pascale Quéré, Karine Germain, Frédéric Lévy, Scott A. Love, Aline Bertin, Cécile Arnould

Published in 2024

Scientific article reporting that hens display increased redness of the facial skin in situations eliciting positive or negative affective states, with high-intensity negative situations resulting in the highest degree of redness. Meanwhile, situations could produce minor changes in immunoglobulin A concentrations. The authors conclude that changes in facial skin redness do indeed reflect variations in the hens' affective states and can be used as a marker when assessing the quality of the human-hen relationship.

The potential of pumice as a litter material and its influence on growth performance, carcass parameters, litter quality traits, behavior, and welfare in broiler chickens

Duman, M., Şekeroğlu, A. & Tainika, B

Published in 2024

Scientific study showing the potential of pumice as a bedding material to improve the zootechnical performance, behavior and welfare of broiler chickens. The article concludes that acid pumice, either on its own or mixed with wood shavings, would provide a reliable litter material, replacing wood shavings.

Assessing Giraffe Welfare During Seasonal Habitat Changes in Northern US Zoos

Razal, C., Bryant, J., & Miller, L.

Published in 2024

Multi-criteria study of behavioral observations, hormonal monitoring and decubitus rates as a means to assess giraffe welfare, comparing summer outdoor habitats and winter indoor quarters at several zoological institutions. The results suggest that housing giraffes indoors does not compromise their welfare, since positive effects were observed in both indoor and outdoor surroundings.

Producer perceptions of dairy calf management, behavior, and welfare

S.B. Doyle, C.L. Wickens, J.M.C. Van Os, E.K. Miller-Cushon

Published in 2024

Results of a survey to gain an understanding of dairy calf farmers' perceptions of the management, behavior and welfare of their animals. Farmers seemed to attach great importance to the welfare of their calves. Those who installed group housing were more interested in the subjective welfare of their calves. Individual perceptions of animal welfare would appear to depend on the respondents' practical experience.

Catcalls: exotic cats discriminate the voices of familiar caregivers

Crews T, Vonk J, McGuire M.

Published in 2024

Scientific study on whether undomesticated Felidae species recognize familiar human voices by exposing them to audio playbacks of familiar and unfamiliar humans using the cats' names and measuring the latency, intensity and duration of the cats' responses. The results suggest that close human contact rather than domestication is associated with the ability to distinguish between human voices, and that less social species may have socio-cognitive abilities similar to those of more gregarious species.
