Eliminating light-at-night contamination during a lab animal facility renovation

Relocating laboratory animal research from one animal facility room to another in advance of major renovations can be a daunting task for scientists and animal care personnel alike. This is especially so regarding controlled lighting and the elimination of light-at-night...

Evaluation of an acute osmotic stress in European sea bass via skin mucus biomarkers

European sea bass is a marine teleost which can inhabit a broad range of environmental salinities. So far, no research has studied the physiological response of this fish to salinity challenges using modifications in skin mucus as a potential biological...

Feeding cats for optimal mental and behavioral well-being

In this article, we review cats' feeding behaviors, and discuss ways of feeding cats that promote physical and mental/behavioral health, while providing cats with choices that allow expression of preferences. We address the management of several feeding issues that cat...

Field assessment in single-housed cats of litter box type (covered/uncovered) preferences for defecation

Cats living without any outdoor access have to use litter boxes to eliminate. A lack of cleanliness is one of the main reasons for which cat owners consult their veterinarian. What has been identified as one of the major causes...

Floor substrate preferences of chickens: A meta-analysis

Environmental enrichment promotes sensory and motor stimulation for species-typical behaviors, which in turn enhance animal well-being. For farmed Galliformes, housing systems often limit enrichment to bedding and litter, that simultaneously act as material for dustbathing and foraging. Therefore, this meta-analysis...

Food preference and nutrient composition in captive bonobos (Pan paniscus)

Food preference has been studied in a range of Hominoidea in the wild and in captivity, allowing for interspecific comparisons. Chimpanzees (Pan troglodytes) and gorillas (Gorilla gorilla gorilla) prefer low-fibre, high-sugar foods, suggesting that frugivory and their dietary overlap are...

High laboratory mouse pre-weaning mortality associated with litter overlap, advanced dam age, small and large litters

High and variable pre-weaning mortality is a persistent problem in laboratory mouse breeding. Assuming a modest 15% mortality rate across mouse strains, means that approximately 1 million more pups are produced yearly in the EU to compensate for those which...

How dietary diversity enhances hedonic and eudaimonic well-being in grazing ruminants

Ruminants evolved in diverse landscapes of which they utilized, by choice, a diverse arrangement of plants (grasses, forbs, and trees) for food. These plants provide them with both primary (carbohydrates, protein, etc.) and secondary (phenolics, terpenes, etc.) compounds (PPC and...
