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.

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.

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.

Animal welfare review: Sows are more vulnerable towards transport than most other pig categories

EU Reference Centre for Animal Welfare Pigs (EURCAW-Pigs)

Published in 2024

Article on a summary report published by EURCAW-Pigs showing that sows are the pig category most affected by transport. The three risks specific to sows are: sensitivity to heat stress, a lack of transport suitability that is strongly connected to the poor general health of a large proportion of cull sows compared with average finisher sows, and the tendency of sows to fight when mixed with unfamiliar conspecifics.

Veal calf welfare and rearing 

Didier Bastien, Magdéléna Chanteperdrix, Virginie Lefoul, Christophe Martineau, Etienne Labussière, Manuel Tourtier

Published in 2024

Article summarising papers on veal calves given at the 74th European Animal Science Congress (EAAP). The presentations discussed work to identify societal expectations, establish the impact of different housing and feeding methods, evaluate changes in antibiotic use and develop tools for assessing biosecurity on farms.

Pain Mitigation Strategies for Disbudding in Goat Kids

Preet Singh, Dinakaran Venkatachalam, Kavitha Kongara, Paul Chambers

Published in 2024

Scientific synthesis of pain-reduction strategies for kids during disbudding on the farm. The authors conclude that current good practice to reduce pain during disbudding would be the use of sedation/analgesia with an alpha-2 agonist and placement of a two-point cornual nerve block, followed by an NSAID for postoperative pain.

Environmental enrichments and data-driven welfare indicators for sheltered dogs using telemetric physiological measures and signal processing

Tiziano Travain, Teddy Lazebnik, Anna Zamansky, Simona Cafazzo, Paola Valsecchi, Eugenia Natoli

Published in 2024

Scientific article comparing the effects of different types of enrichment on the welfare of male dogs in shelters. The results show that intraspecific social enrichment provided by the presence of a female dog is the best stimulus compared with the presence of either entertaining objects or a human. It improves both sleep quality and the cyclicity of a set of measured physiological parameters.
