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.

Trade-offs in the externalities of pig production are not inevitable

Bartlett H, Zanella M, Kaori B, Sabei L, Araujo MS, de Paula TM, Zanella AJ, Holmes MA, Wood JLN, Balmford A

Published in 2024

Scientific study examining the trade-offs between environmental costs (land use, GHG emissions and use of antimicrobials) and animal welfare costs in pig farming systems. Despite the common view that trade-offs are unavoidable, the study suggests that a focus on reducing impacts within existing systems rather than changing farming type offers the best way to avoid these trade-offs and mitigate externality costs.

Ad libitum feeding systems for lactating sows: effects on productivity and welfare of sows and piglets

Sarah C. Gorr, Christine Leeb, Werner Zollitsch, Christoph Winckler, Thomas D. Parsons

Published in 2024

Scientific article evaluating the effects of three ad libitum feeding systems on the productivity and welfare of suckling sows. Results show that sows fed ad libitum convert feed more efficiently for better piglet growth without additional weight loss. With these systems, sows spend more time feeding, which would meet the pigs' behavioral need to forage.

Fowl language: AI is learning to analyze chicken communications to help us understand what all the clucking's about

Suresh Neethirajan

Published in 2024

Popular science article on the benefits of an AI tool to interpret the complex vocal linguistic system used by chickens. Combined with an analysis of non-vocal cues, the tool would make it possible to understand the birds' emotional states. This interpretation of different chicken vocalizations could lead to improved farming practices and a change in how we view our relationship with animals.

Air bubble curtain improves the welfare of captive rainbow trout fry and fingerlings

Océane Amichaud, Thomas Lafond, Georgina Lea Fazekas, Aude Kleiber, Thierry Kerneis, Axel Batard, Lionel Goardon, Laurent Labbé, Sophie Lambert, Sylvain Milla, Violaine Colson

Published in 2024

Scientific article showing that the repeated diffusion of bubbles in a tank improved the welfare of rainbow trout. The short-term (~7 weeks) and long-term (~21 weeks) enrichment effects were similar to those observed with more conventional environmental enrichment (provision of plants and shelter). The fish were less aggressive, less fearful and showed enhanced learning abilities.

Research Note: Welfare and stress responses of broiler chickens raised in conventional and animal welfare-certified broiler farms

Kwon Byung-Yeon, Lee Hyun-Gwan, Jeon Yong-Sung, Song Ju-Yong, Kim Sang-Ho, Kim Dong-Wook, Kim Chan-Ho, Lee Kyung-Woo

Published in 2024

Study comparing the welfare of broilers reared on conventional and welfare-certified farms. Chickens on the certified farm scored lower hock burn and feather dirtiness and had better gait scores, although corticosterone levels in feathers were higher, warranting further study.
