Fecal glucocorticoid metabolites as stress biomarkers in common buzzards (Buteo buteo) across rehabilitation phases: Implications for raptor welfare

Taking wildlife into human care is a balancing act between benefits and harms, as handling and captivity can cause chronic stress that can lead to permanent physiological changes. Therefore, it is necessary to investigate stress levels during the rehabilitation of...

Role of illumination and light colour temperature in the preference behaviour of weaned piglets

This study investigated the preference behaviour of 24 four-week-old weaned piglets under different lighting conditions (0 lux with 0 Kelvin vs. 80 lux with 3000 Kelvin vs. 6500 Kelvin). Two trials with 12 piglets each were conducted over five weeks...

Identification and validation of operational pain indicators in anurans

Amphibian welfare, particularly pain assessment in anurans, remains understudied despite their ecological and biomedical significance. This study aimed to identify and validate operational pain indicators for adult anurans under professional care. A four-phase approach was used: a systematic literature review,...

Environmental enrichment influences the relationship between lateralization and neophobia in zebrafish larvae

Neophobia, the aversion to novelty, is a conserved survival trait that influences individuals’ decision-making. In many species, juveniles showed less avoidance of novelty than adults, likely due to their limited experience and their need to gather environmental information. A challenging...

Impact of different stocking densities on growth performance, welfare and physiology of Litopenaeus vannamei in RAS

Optimal stocking density allows shrimp farmers to maximise profit while maintaining animal welfare. To date, holistic assessments of chronic crowding stress effect on Litopenaeus vannamei are lacking regarding biological impairments, stress-related behaviors, and recovery capacity. Twelve tanks of a recirculation...

Intertwining of the IGF system and animal welfare

To date, husbandry categories are defined based on the human concept of animal needs, however, to objectively assess animal welfare in defined husbandry systems, animal-related indicators must be evaluated. Here, we studied the impact of differential housing conditions on factors...

The influence of different light spectra on broiler chicken endocrine systems and productivity

In birds, light can penetrate the cranial bones and reach deep brain regions, where non-visual photoreceptors, especially in the hypothalamus, detect spectral and photoperiodic cues. Alongside retinal photoreception, deep-brain light sensing contributes to circadian entrainment and regulates melatonin secretion by...

Environmental exposure to the common trunk of mammalian appeasing pheromone modulates social behavior and reduces fight wounds in male mice

Aggression among group-housed male laboratory mice poses significant challenges for animal welfare and scientific outcomes. Semiochemicals, such as mammalian appeasing pheromones, have shown potential in modulating social behaviors in various species. This study aimed to evaluate the effects of a...

Fish welfare in recirculating aquaculture systems (RAS): The imperative for environmental enrichment (EE)

Aquaculture has become the fastest-growing food production sector worldwide, recently surpassing wild-capture fisheries in total output. This rapid expansion underscores the need to ensure sustainability through robust animal welfare standards. Recirculating Aquaculture Systems (RAS) are increasingly adopted due to their...

Pasture heterogeneity improves donkey welfare: Effects of structural variation, species diversity, and sward height on herd emotional states

Grazing environment plays a key role in the welfare of domestic herbivores. In the UK, donkeys are typically kept on species-poor, agriculturally improved grasslands that offer limited dietary and behavioural opportunities. Obesity, driven by low exercise levels and unsuitable diet,...
