Naked Mole rat modular housing system

Naked Mole-rats have been studied in laboratories for decades due to their unique behavior and physiology. They are one of a few species of mammals that maintain a hive social structure, are highly resistant to cancer, and can survive and...

Using restaurant glassware and flatware wash racks for washing water bottles and cage accessories

In the event of an emergency resulting in our automatic watering system being shut off, we identified the need to increase the number of rodent water bottles we have on hand. Once we realized we had a limited number of...

Compressed paper column housing enrichment for Naked Mole-rats

Naked Mole-rats are relative newcomers in the research world. Due to the complexity of their natural subterranean tunneling system, it has been difficult to replicate in the laboratory environment. Housing standards often differ from the hard solidified lateritic loam soils...

Modernization of wall guard railing for safe enrichment in feline housing facilities

Creatively adapting older lab animal housing spaces to improve psychological well-being, welfare, and safety for animals is necessary to meet expectations for animal enrichment. Traditional lab animal facilities are designed to have functional, flexible, durable, and sanitizable housing spaces. Many...

Environmental enrichment: Dissociated effects between physical activity and changing environmental complexity on anxiety and neurogenesis in adult male Balb/C mice

Several factors, including environmental modifications, stimulate neuroplasticity. One type of neuroplasticity consists in the generation of new neurons in the dentate gyrus of the hippocampus. Neurogenesis is modulated by environmental enrichment (ENR, tunnels plus running wheel) and affected by the...

A multicentre study on spontaneous in-cage activity and micro-environmental conditions of IVC housed C57BL/6J mice during consecutive cycles of bi-weekly cage-change

Mice respond to a cage change (CC) with altered activity, disrupted sleep and increased anxiety. A bi-weekly cage change is, therefore, preferred over a shorter CC interval and is currently the prevailing routine for Individually ventilated cages (IVCs). However, the...

Pivotal role of micro-CT technology in setting up an optimized lung fibrosis mouse model for drug screening

Idiopathic pulmonary fibrosis (IPF) is a progressive disease with no curative pharmacological treatment. The most used animal model of IPF for anti-fibrotic drug screening is bleomycin (BLM)-induced lung fibrosis. However, several issues have been reported: the balance among disease resolution,...

Systematic review of animal-based indicators to measure thermal, social, and immune-related stress in pigs

The intense nature of pig production has increased the animals' exposure to stressful conditions, which may be detrimental to their welfare and productivity. Some of the most common sources of stress in pigs are extreme thermal conditions (thermal stress), density...

Dairy cows value an open area for lying down

As dairy cows are being housed for longer periods, with all-year-round housing growing in popularity, it is important to ensure housed environments are meeting the needs of cows. Dairy cows are motivated to access open lying areas, although previous motivation...

Introduction of gloved hand to cage induces 22-kHz ultrasonic vocalizations in male albino rats

Rodents emit ultrasonic vocalizations (USVs) above the human hearing threshold of ~ 20 kHz to communicate emotional states and to coordinate their social interactive behavior. Twenty-two kHz USVs emitted by adult rats have been reported in a variety of aversive...
