Weight as an indicator of enclosure suitability in Livingstone’s fruit bats (Pteropus livingstonii)

Obesity is common in zoo animals, and both dietary management and the provision of adequate opportunities for exercise are needed to tackle it. We used 30 years of records from Jersey Zoo to compare the weight and forearm length of...

Pharmacokinetic evaluation of a topical extended-release analgesic in mice

Mice often undergo painful procedures and surgeries as part of biomedical research protocols. Buprenorphine, a partial μ-opioid receptor agonist and κ receptor antagonist, is commonly used to alleviate the pain associated with such procedures. Due to its pharmacokinetic profile, buprenorphine...

Voluntary wheel running as an effective intervention in the management of excessive food usage in CD-1 mice (Mus musculus)

Some mice demonstrate excessive food-grinding behaviors in which food pellets are broken down into crumbs (orts). This is considered abnormal behavior and is undesirable in a research environment, as it is thought to potentially be a stereotypic behavior suggestive of...

Refined tamoxifen administration in mice by encouraging voluntary consumption of palatable formulations

Drug administration in preclinical rodent models is essential for research and the development of novel therapies. Compassionate administration methods have been developed, but these are mostly incompatible with water-insoluble drugs such as tamoxifen or do not allow for precise timing...

The use of rabbits used to propagate human lice for research

The globally important human diseases of trench fever, epidemic typhus, and relapsing fever are vectored by the human louse Pediculus humanus humanus. Although these conditions are epidemically quiescent at present, they persist in socially dysfunctional situations of war, deprivation, and...

Sedation efficacy of midazolam in conjunction with ketamine and alfaxalone in female laboratory guinea pigs (Cavia porcellus)

Guinea pigs have been integral as models used in biomedical research, making significant contributions to nutritional, auditory, immunologic, and hypersensitivity studies, and necessitating the routine need for sedation in laboratory settings. The ketamine-xylazine (KX) combination has been the standard sedation...

Effect of adopting a timothy hay–based diet at weaning or in adulthood on urinary tract parameters in strain 13/N guinea pigs (Cavia porcellus)

Type of feed is an important consideration in herbivore colony management, yet limited studies report on the effects of diet on common conditions such as urolithiasis in guinea pigs. Urolithiasis is a well-documented cause of lower urinary tract disease in...

Can you dig it? The impact of a movable substrate “dig pit” on naked mole rat (Heterocephalus glaber) behavior and welfare

Zoos are often limited by exhibit design in the opportunities they can provide animals to express natural behaviors; however, the opportunity to perform certain natural behaviors is key to supporting good animal welfare. Traditionally, in zoos, naked mole rats (Heterocephalus...

Effects of supplemental diet during breeding on fertility, litter size, survival rate, and weaning weight in mice (Mus musculus)

The addition of supplemental diets to laboratory animals, specifically rodents, is a common practice for the provision of additional nutritional support. We set out to investigate whether the use of commercially available supplemental diets during breeding affected fertility rate, litter...

Evaluation of efficacy of 2 extended-release bupivacaine products in a porcine model of incisional pain

Extended-release (ER) local anesthetics are often incorporated in multi-modal analgesia or as an alternative when the effect of systemic analgesics may confound research. In this study, we compared the analgesic efficacy of 2 ER bupivacaine anesthetics with different ER mechanisms,...
