Effects of age and feeding protocols on the metabolic and physiological condition of unweaned calves during and after long-distance transport

Susanne Siegmann, Luca L. van Dijk, Niamh L. Field, Gearoid Sayers, Katie Sugrue, Cornelis G. van Reenen, Eddie A. M. Bokkers, Muireann Conneely

Published in 2026

Study on the effects of long journeys and the fasting involved on the physiological condition of young, unweaned calves. Provision of 4 L of milk before transport slightly improves their energy balance and hydration compared to 2 L, but only partially offsets the negative effects of long-distance transport.

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.
