Knowledge of lateralized brain function can contribute to animal welfare

Lesley J. Rogers

Published in 2023

Scientific review of the relationship between hemispheric lateralization and behavior in animals. Experiments have shown an association between right-limb preference and positive cognitive bias, and left-limb preference and negative cognitive bias. Animals with weak lateralization tend to be more stressed, fearful and aggressive than those with strong lateralization.

Reducing Weaning Stress in Piglets by Pre-Weaning Socialization and Gradual Separation from the Sow: A Review

Céline Van Kerschaver, Diana Turpin, Joris Michiels, John Pluske

Published in 2023

Scientific review of alternative piglet management strategies to reduce weaning stress. These include the pre-weaning grouping of piglets from different litters and intermittent suckling. Their effects on post-weaning pig behavior, performance, mortality, gastrointestinal function and immunocompetence are described.

Effects of improved early-life conditions on health, welfare, and performance of pigs raised on a conventional farm

S. Gavaud, K. Haurogné, A. Buchet, I. Garcia Vinado, M. Allard, A. Lehébel, M. Leblanc-Maridor, J.M. Bach, C. Belloc, B. Lieubeau, J. Hervé

Published in 2023

Scientific paper to examine the effects of the complete elimination of painful procedures and of reducing weaning stressors in the living conditions of piglets on a commercial farm. This form of management resulted in improved innate immunity at weaning, fewer and less severe body lesions but more tail lesions than in the control pigs.
