Head, V., Eshar, D., Nau, M. R. 2017. Techniques for nonterminal blood sampling in black-tailed prairie dogs (Cynomys ludovicianus). JAALAS 56(2), 210-213.

Black-tailed prairie dogs (Cynomys ludovicianus) are used as an animal model for research on gallbladder stones and several infectious diseases. A comprehensive, instructive resource regarding the appropriate techniques for venipuncture and collection of nonterminal blood...

Rapp-Santos, K. J., Altamura, L. A., Norris, S. L. et al. 2017. Comparison of saliva collection methods for the determination of salivary cortisol levels in rhesus macaques (Macaca mulatta), cynomolgus macaques (Macaca fascicularis)

The ability to quickly and accurately determine cortisol as a biomarker for stress is a valuable tool in assessing the wellbeing of NHP. In this study, 2 methods of collecting saliva (a commercial collection device...

Moore, E. S., Cleland, T. A., Williams, W. O. et al. 2017. Comparing phlebotomy by tail tip amputation, facial vein puncture, and tail vein incision in C57BL/6 mice by using physiologic and behavioral metrics of pain and distress. JAAL

Tail tip amputation with minimal restraint is not widely used for mouse phlebotomy. In part, this infrequency may reflect policies influenced by tail tip amputation procedures for genotyping, which involve greater handling and tissue removal...

Hoffman, J. F., Fan, A. X., Neuendorf, E. H. et al. 2018. Hydrophobic sand versus metabolic cages: A comparison of urine collection methods for rats (Rattus norvegicus). JAALAS 57(1), 51-57.

A common method for urine collection from rats requires the use of a metabolic cage, thus exposing animals to extended periods of isolation in an unfamiliar cage with a wire-mesh floor. A new method involving...

Frohlich, J. R., Alarcón, C. N., Toarmino, C. R. et al. 2018. Comparison of serial blood collection by facial vein and retrobulbar methods in C57BL/6 mice. JAALAS 57(4), 382-391.

Many biomedical research protocols for mouse models involve serial blood collection and analysis. Two common techniques for serial blood collection in this species are the retrobulbar (RB, also called retroorbital) and facial vein (FV) methods...

Gaskill, B. N., Stottler, A. M., Garner, J. P. et al. 2017. The effect of early life experience, environment, and genetic factors on spontaneous home-cage aggression-related wounding in male C57BL/6 mice. Lab Animal 46(4), 176-184.

Aggression is a major welfare issue in mice, particularly when mice unfamiliar to each other are first placed in cages, as happens on receipt from a vendor, and following cage cleaning. Injuries from aggression are...

Joyce-Zuniga, N. M., Newberry, R. C., Robbins, C. T. et al. 2016. Positive reinforcement training for blood collection in grizzly bears (Ursus arctos horribilis) results in undetectable elevations in serum cortisol levels: A preliminary investigat

Training nonhuman animals in captivity for participation in routine husbandry procedures is believed to produce a lower stress environment compared with undergoing a general anesthetic event for the same procedure. This hypothesis rests largely on...

Amen, E. M., Brecheisen, M., Sach-Peltason, L. et al. 2017. Refinement of a model of repeated cerebrospinal fluid collection in conscious rats. Laboratory Animals 51(1), 44-53.

The cannulation of the cisterna magna in rats for in vivo sampling of cerebrospinal fluid serves as a valuable model for studying the delivery of new drugs into the central nervous system or disease models...

Harikrishnan, V. S., Hansen, A. K., Abelson, K. S. P. et al. 2018. A comparison of various methods of blood sampling in mice and rats: Effects on animal welfare. Laboratory Animals 52(3), 253-264.

This study was conducted to investigate the effects of blood sampling on animal welfare in a total of 60 NTac:SD rats and 72 C57BL/6NTac mice of both sexes. Blood was sampled either by sublingual vein...

Rodrigues, M. V., de Castro, S. O., de Albuquerque, C. Z. 2017. The gingival vein as a minimally traumatic site for multiple blood sampling in guinea pigs and hamsters. PLOS ONE 12(5), e0177967.

Laboratory animals are still necessary in scientific investigation and vaccine testing, but while novel methodological approaches are not available for their replacement, the search for new, humane, easy, and painless methods is necessary to diminish...
