Hurtado-Parrado, C., Cardona-Zea, Á, Arias-Higuera, M. et al. 2019. Behavioral patterns of laboratory Mongolian gerbils by sex and housing condition: A case study with an emphasis on sleeping patterns. Journal of Veterinary Behavior 30, 69-79.

The behavioral patterns of Mongolian gerbils (Meriones unguiculatus) housed individually and in same-sex groups (siblings) were characterized. Gerbils were continuously video-recorded 24 hours (day 1) and 120 hours (day 5) after housing conditions were established...

Leenaars, C. H. C., Pels, E. G. M., Joosten, R. N. J. M. A. et al. 2019. Wistar rats do not show preference for either of two commonly used nutritionally sound food rewards in a T-maze. Journal of Veterinary Behavior 31, 22-27.

Food rewards are commonly used as positive reinforcement in rodent behavioral experiments. Bioserv dustless precision pellets and Noyes formula P precision pellets are both used for this purpose in behavioral experiments in multiple laboratories, as...

Schneider, B. M., Erhard, M. H., Scheipl, F. et al. 2016. Comparison of 2 gentling programs for laboratory rats: Effects on the behavior toward humans. Journal of Veterinary Behavior 12, 73-81.

Gentling can reduce the fear reactions of young laboratory rats toward people long term. We were able to show this outcome in a previous study that involved a successful but elaborate gentling program. In the...

Franchi, V., Aleuy, O. A., Tadich, T. A. 2016. Fur chewing and other abnormal repetitive behaviors in chinchillas (Chinchilla lanigera), under commercial fur-farming conditions. Journal of Veterinary Behavior 11, 60-64.

Fur chewing is a behavioral disorder frequently reported in chinchillas kept for fur-farming purposes. Rodents kept in barren cages usually develop some form of abnormal repetitive behavior, which can indicate a past or present welfare...

Windsor, Z., Bate, S. T. 2019. Assessing the safety and suitability of nesting material for singly housed mice with surgically fitted head plates. Heliyon 5(7), e02097.

Nesting material, for example shredded paper, is a common form of enrichment for laboratory mice. However, there has been limited research performed regarding its apparent safety when given to mice fitted with exteriorised devices such...

Taylor, J. L., Noel, P., Mickelsen, M. 2019. Evaluation of a 16-week change cycle for ventilated mouse cages. JAALAS 58(4), 443-449.

The methods and conditions for housing research mice have been the subject of many discussions and publications in recent years. At our institution, we began to explore these matters with the goal of reducing stress...

Taitt, K. T., Kendall, L. V. 2019. Physiologic stress of ear punch identification compared with restraint only in mice. JAALAS 58(4), 438-442.

Social housing of laboratory rodents is recommended whenever possible to encourage natural behavior and social dynamics. Several identification methods are used to distinguish rodents from one another. One of the most common means of identifying...

Moffitt, A. D., Brignolo, L. L., Ardeshir, A. et al. 2019. The role of emotional contagion in the distress exhibited by grouped mice exposed to CO2. JAALAS 58(4), 430-437.

The 2013 AVMA Guidelines for the Euthanasia of Animals recommends a chamber volume displacement rate of 10% to 30% per minute (v/min) when euthanizing small laboratory rodents with CO2. Group euthanasia of mice is a...
