La douleur et la souffrance des poissons sont-elles suffisamment considérées en aquaculture et pêche ?

Marie-Laure Bégout

Published in 2024

Article following on from the FRCAW report on the slaughter of farmed fish. Ifremer reviews the capacity of fish to feel pain, their legal status, and appropriate slaughter methods. Making pre-slaughter stunning compulsory in France would require investment and an overhaul of the way businesses organize their work, but other countries such as Norway have already done so.

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.

The behavior and welfare of neglected species: some examples from fish and mammals

Bukhari SSUH, Parkes RSV, Sneddon LU, McElligott AG

Published in 2024

Synthesis of concepts and methods for assessing animal welfare through the study of behavior, illustrated by work on certain "neglected" species (buffalo, camels, donkeys, mules and lumpfish). The authors conclude that there is an extreme lack of balance in the species generally studied in research on animal welfare.

What We (Don't) Know about Parrot Welfare: A Systematic Literature Review

Andrea Piseddu, Yvonne van Zeeland, and Jean-Loup Rault

Published in 2024

Synthesis of the scientific literature examining potential welfare indicators applicable to pet parrots. The study identifies indicators such as behavioral changes (activity level, social interactions, exploration), body measurements (weight, plumage condition) and abnormal behaviors. These results serve as a starting point for work on a species that is rarely studied.

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.
