Exploring the relationship between whole carcass condemnations and farm animal welfare: A rapid scoping review

Christine Kuo, Emma G. Gardner, Murray Gillies, Marianne I. Parent

Published in 2026

Literature review showing that data on carcass rejection at abattoirs can serve as an indirect indicator of animal welfare, but studies remain largely European and focus primarily on poultry. Their main focus is on links between animal health status on farms and carcass rejection, whereas research on other welfare factors (diet, housing, behavior, transport) is limited.

Animal Board Invited Review: Intrinsic hedonic value, complexity, and possibility for action as essential characteristics of a welfare-friendly environment for animals

I. Veissier, C. Terlouw, R. Botreau, V. Deiss, S. Cowie

Published in 2026

Study examining how the hedonic value of the environment determines animal welfare. Welfare depends on a balance between positive emotions, environmental complexity and opportunities for behavioral expression: these factors must be optimized (rather than maximized), since an excess or a deficiency of any one of them can be harmful to welfare, with the optimal level varying by individual.
