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.

Providing elevated structures in the pullet rearing environment affects behavior during initial acclimation to a layer aviary

Allison N. Pullin, Christina B. Rufener, Suzanne T. Millman, John F. Tarlton, Michael J. Toscan

Published in 2024

Scientific article reporting that hens with access to elevated platforms during the rearing phase make better use of the space in laying aviaries when they are first transferred there than those reared on the ground. The latter acclimatize within 1-2 weeks, but continue to make little use of the highest level of the aviary.
