Use of air-activated thermal devices during recovery after surgery in mice

Laboratory mice (Mus musculus) are susceptible to hypothermia, especially during anesthetic events, disease states, and exposure to environmental stressors. Thermal support devices for small mammals are numerous, but often require a power source and may be impractical to use for...

Effect of environmental enrichment on aggression in BALB/cJ and BALB/cByJ mice monitored by using an automated system

Aggression among mice remains a common undesirable problem in laboratory settings, and animal welfare and scientific outcomes may become compromised depending on the severity of aggression. This study evaluated the effect of cage enrichment comprising a bilevel, mounted 'mezzanine' compared...

Analgesic efficacy and hematologic effects of robenacoxib in mice

NSAID analgesics may confound models that require inflammation to mimic disease development in humans. This effect presents a challenge for veterinary staff and investigators, because surgery is often necessary to create mouse models of disease and NSAID are first-line analgesics...

Refinement of perioperative feeding in a mouse model of vertical sleeve gastrectomy

Provision of liquid enteral nutrition (LEN) during the perioperative period is standard practice for rodents undergoing bariatric surgery, yet these diets are associated with several challenges, including coagulation of the liquid diet within the delivery system and decreased postoperative consumption....

Out like a light? The effects of a diurnal husbandry schedule on mouse sleep and behavior

Sleep disruption in humans, caused by shift work, can be detrimental to physical and behavioral health. Nocturnal laboratory mice may experience a similar disruption caused by human daytime activities, but whether this disruption affects their welfare is unknown. We used...

Using cageside measures to evaluate analgesic efficacy in mice (Mus musculus) after surgery

Recent studies have revealed some of the most frequently used analgesics in mice are not effectively treating postoperative pain. Our laboratory sought to compare and assess the validity and reliability of 2 cageside pain assessments that we recently developed for...

A good death? Report of the second Newcastle meeting on laboratory animal euthanasia

Millions of laboratory animals are killed each year worldwide. There is an ethical, and in many countries also a legal, imperative to ensure those deaths cause minimal suffering. However, there is a lack of consensus regarding what methods of killing...

Effects of various cleaning agents on the performance of mice in behavioral assays of anxiety

Cleaning behavioral equipment between rodent subjects is important to prevent disease transmission and reduce odor cues from previous subjects. However, the reporting regarding the cleansing procedures used during such experiments is sporadic and often incomplete. In addition, some investigators are...

Effects of nesting material on the toxicologic assessment of cyclophosphamide in Crl:CD1(ICR) mice

The provision of nesting material benefits mice by reducing cold stress, improving feed conversion, increasing litter size, and improving adaptive immunity. The effects of toxins are sensitive to environmental changes, and the introduction of novel items can alter results in...
