Jacob, G., Katti, H., Cherian, T. et al. 2021. A naturalistic environment to study visual cognition in unrestrained monkeys. eLife 10, e63816.

Macaque monkeys are widely used to study vision. In the traditional approach, monkeys are brought into a lab to perform visual tasks while they are restrained to obtain stable eye tracking and neural recordings. Here...

Neto, T., Faustino-Rocha, A. I., Gil da Costa, R. M. et al. 2022. A quick and low-intensity method for oral administration to large numbers of mice: A possible alternative to oral gavage. Laboratory Animals 56(2), 185-190.

Oral administration of medication to experimental animals is a cause of significant stress. When coupled to animals who are already under strenuous circumstances due to the disease being modelled, there is a significant risk for...

Chesler, K. C., Motz, C. T., Bales, K. L. et al. 2022. Voluntary oral dosing for precise experimental compound delivery in adult rats. Laboratory Animals 56(2), 147-156.

Preclinical drug studies routinely administer experimental compounds to animal models with the goal of minimizing potential adverse events from the procedure. In this study, we assessed the ability to train adult male Long Evans rats...

Zevnik, B., Jerchow, B., Buch, T. 2022. 3R measures in facilities for the production of genetically modified rodents. Lab Animal 51(6), 162-177.

Sociocultural changes in the human–animal relationship have led to increasing demands for animal welfare in biomedical research. The 3R concept is the basis for bringing this demand into practice: Replace animal experiments with alternatives where...

Martin-Flores, M., Sakai, D. M., Marra Muto, R. et al. 2022. A flexible endotracheal tube introducer improves first-attempt success of intubation in cats by novice anesthetists. Journal of the American Veterinary Medical Association

OBJECTIVE: To test whether the use of a flexible endotracheal tube introducer (ETI) facilitates intubation of cats by veterinary students with little or no experience. ANIMALS: 125 healthy cats. PROCEDURES: Cats were sedated with dexmedetomidine...

O’Neil, B. A., Linklater, A. K J. 2022. Supplemental reflective blankets and wool socks help maintain body temperature in dogs undergoing celiotomy procedures: A prospective randomized controlled clinical trial. Journal of the American

OBJECTIVE: To compare results for body (esophageal) temperature measurements obtained during celiotomy in normothermic (presurgical) canine patients receiving routine heat support versus routine heat support plus supplemental support (consisting of covering the thorax in a...

Barkus, C., Bergmann, C., Branco, T. et al. 2022. Refinements to rodent head fixation and fluid/food control for neuroscience. Journal of Neuroscience Methods 381, 109705.

The use of head fixation in mice is increasingly common in research, its use having initially been restricted to the field of sensory neuroscience. Head restraint has often been combined with fluid control, rather than...

Bailey, K. T., Jantre, S. R., Lawrence, F. R. et al. 2022. Evaluation of active warming and surgical draping for perioperative thermal support in laboratory mice. JAALAS 61(5), 482-494.

Surgical procedures are commonly performed using mice but can have major effects on their core body temperature, including development of hypothermia. In this study, we evaluated active perioperative warming with and without surgical draping with...

LeFors, J. E., Anderson, L. M., Hanson, M. A. et al. 2022. Assessment of 2 hair removal methods in New Zealand white rabbits (Oryctolagus cuniculus). JAALAS 61(3), 296-303.

Rabbits are frequently used as surgical models in research. However, studies assessing the effects of various hair removal methods on wound healing and surgical site infection (SSI) in rabbits are sparse. Here we evaluated the...

Ahrens Kress, A. P., Zhang, Y., Kaiser-Vry, A. R. et al. 2022. A Comparison of blood collection techniques in mice and their effects on welfare. JAALAS 61(3), 287-295.

Multiple methods are used to collect blood from mice; these methods have different effects on animal welfare. This study compared blood collection from facial, chin, and saphenous locations with regard to various parameters, including the...
