Use of a toy soak to maximize staff efficiency in cage wash operations

The Guide for the Care and Use of Laboratory Animals emphasizes that the primary aim of environmental enrichment is to enhance animal well-being. At our facility, at the end of a two-week cycle in a rodent cage, enrichment accessories and...

Comparison of three environmentally friendly enrichments in single-housed Sprague Dawley rats

Numerous studies have shown the negative side effects the lack of enrichment has on the overall health of animals in research. This lack in data may lead to unnecessary risks for welfare issues, like the single housed lab rats that...

Overcoming the hurdles of lab animal enrichment: Natural behaviors vs. scientific need

The Animal Resources Core (ARC) at the Abigail Wexner Research Institute (AWRI) at Nationwide Children's Hospital (NCH) faces many of the same challenges other institutions manage in terms of enrichment for laboratory animals. A Behavior Assessment Team (BAT) was developed...

Plasma metabolomics supports non-fasted sampling for metabolic profiling across a spectrum of glucose tolerance in the Nile rat model for type 2 diabetes

Type 2 diabetes is a challenge in modern healthcare, and animal models are necessary to identify underlying mechanisms. The Nile rat (Arvicanthis niloticus) develops diet-induced diabetes rapidly on a conventional rodent chow diet without genetic or chemical manipulation. Unlike common...

Why all healthy laboratory animals should be rehomed, no matter how small

This paper explores the ethical imperative of rehoming all healthy animals of sentient species after experiments have finished or when they have become otherwise redundant. We take into account disparate perspectives in animal ethics and see how they point in...

Chronic social comparison elicits depression- and anxiety-like behaviors and alterations in brain-derived neurotrophic factor expression in male rats

Social comparison is a fundamental human characteristic; however, long-term social comparison may induce psychological stress and can lead to depression and anxiety. Recent studies have shown that nonhuman primates compare themselves with others; however, no studies have investigated whether social...

Behavioral correlates of 50-kHz ultrasonic vocalizations in rats: Progressive operant discrimination learning reduces frequency modulation and increases overall amplitude

Ultrasonic vocalizations (USVs) in rats are thought to contain ecological signals reflecting emotional states. These USVs are centered on 50-kHz, and frequency modulation (FM) is hypothesized to indicate positive emotion; however, results from recent studies are inconsistent with this hypothesis....

A mild stressor induces short-term anxiety and long-term phenotypic changes in trauma-related behavior in female rats

Introduction: Anxiety and anxiety-influenced disorders are sexually dimorphic with women being disproportionately affected compared to men. Given the increased prevalence in women and the documented differences in anxiety and trauma behavior between male and female rats this paper sought to...
