Effect of novel high-fat diet feeding methods on food wastage, weight gain, hair coat grease accumulation, and scratching behavior in C57BL/6NCrl mice

Soft-pelleted, high-fat diets (HFD) are greasy and crumble easily leading to food wastage and hair coat grease accumulation when mice are fed using commercially available feeders. The ideal HFD feeder design should reduce food wastage, facilitate mouse weight gain, and...

Behavioral or nutritional drive: Which motivation affects rates of food grinding in CD1 mice?

Wire mouse feeders used in laboratory mouse cages typically hold enough food to feed 5 mice for two weeks. However, some mice gnaw the food provided into powder, which they do not ingest. The ground-up food fills the cage, resulting...

Analysis of individually ventilated cage (IVC) microenvironments during 21-d cage change frequency for mice using two different bedding types

The Guide for the Care and Use of Laboratory Animals provides recommendations on sanitation frequencies for rodent caging equipment; however, it allows for performance standards to be used when extending this frequency for individually ventilated cage (IVC) caging. Our institution...

Light cycle phase effects on behavioral responses to stress exposure in rats

Animal models enable investigation of the impact of stress on emotional-behavioral performance to facilitate understanding of posttraumatic stress symptoms experienced in humans. Refinement of animal stress models could lead to a reduction in the number of subjects needed to detect...

Behavioral differences of shelter dogs under fluorescent versus LED lighting

Fluorescent lighting is used in a wide variety of applications, most commonly because of its energy and heat saving capabilities. However, the flicker that accompanies fluorescent light can negatively impact humans and animals. Detrimental behavioral and physiological consequences have been...

Hide-and-seek: Examining hide preferences and behavior patterns of reptiles through 24-hour monitoring (2025)

Providing animals in zoos with private, out-of-view areas is a basic need for many species but has been rarely studied systematically. Recent research on reptiles has highlighted the welfare benefits of complex environments but, as these studies typically include private...

A cross-sectional study to investigate associations between flooring substrates and prevalence of limb and paw abnormalities of dogs housed in commercial breeding facilities (2025)

Understanding the impact of environmental and management factors on the health and behavior of dogs housed in commercial breeding (CB) facilities is critical to their welfare. The specific aims of the study were to assess (a) associations between combinations of...
