Oddsdóttir, C., Jónsdóttir, H. K., Sturludóttir, E. et al. 2024. The effect of repeated blood harvesting from pregnant mares on haematological variables. Animals 14(5), 745.

Studies have been carried out on the effect of large-volume blood harvesting from horses, but they were performed on nonpregnant horses of various breeds other than Icelandic horses. This study aimed to investigate the effect...

Colloff, A., Baker, S. E., Beausoleil, N. J. et al. 2024. Use of an expert elicitation methodology to compare welfare impacts of two approaches for blood sampling European badgers (Meles meles) in the field. Animal Welfare 33, e17.

In the UK and Republic of Ireland, the European badger (Meles meles) is considered the most significant wildlife reservoir of the bacterium Mycobacterium bovis, the cause of bovine tuberculosis (bTB). To expand options for bTB...

Alstrup, A. K. O., Thea Pinholt Lillethorup, Landau, A. M. et al. 2024. The arterial blood sampling associated with PET imaging studies can lead to post-scan complications in Göttingen minipigs. Scandinavian Journal of Laboratory Animal Science 50, 6

When disease progression or treatment effects are investigated, pigs are frequently used for imaging studies. We recently showed that prolonged anesthesia with intensive blood sampling and road transportation affect internal organs in non-recovery imaging studies...

Lawton, S. B., Grobe, C. C., Reho, J. J. et al. 2024. Differences in fluid, electrolyte, and energy balance in C57BL/6J mice (Mus musculus) in metabolic caging at thermoneutral or standard room temperatures. JAALAS 63(2), 190–200.

The Guide for the Care and Use of Laboratory Animals recommends mice be pair or group housed and provided with nesting materials. These provisions support social interactions and are also critical for thermoregulatory behaviors such...

Thiel, A., Hertel, A. G., Giroud, S. et al. 2023. The cost of research: Lasting effects of capture, surgery and muscle biopsy on brown bear (Ursus arctos) movement and physiology. Animal Welfare 32, e75.

Animal models are a key component of translational medicine, helping transfer scientific findings into practical applications for human health. A fundamental principle of research ethics involves weighing the benefits of the research to society against...

Stærk, K., Langhorn, L., Andersen, T. E. 2023. Clean-catching urine from pigs: A method for collecting quality specimens for urinalysis and microbiological culturing in a laboratory environment. Laboratory Animals 57(3), 293–303.

Urine is an important biological specimen for assessing various metabolic functions and drug clearance. In urinary tract infection research, urine is particularly important as urinary bacterial titres constitute the main diagnostic outcome for assessing the...

George, A. J., Harmsen, B. J., Ford, J. A. et al. 2023. Evaluation of submental blood collection in mice (Mus musculus). JAALAS 62(1), 92–98.

The submental route is an option for nonterminal and serial blood collection in mice. This study compared the submental route to the maxillary route (also referred to as the submandibular route). The study used male...

Lelláková, M., Pavľak, A., Lešková, L. et al. 2023. Monitoring blinks and eyelid twitches in horses to assess stress during the samples collection process. Journal of Applied Animal Welfare Science 26(4), 530–539.

To assess stress in horses, a method of monitoring eye blinks (full and half) and eyelid twitches while collecting saliva and blood samples before and after annual intensive police training was carried out. This noninvasive...

Kaleel, K. L., Secoura, P. L., Muñoz-Pérez, J. P. et al. 2024. Endoscopy and rectal enema for fecal collection in wild sea turtles (Chelonia mydas, Eretmochelys imbricata) in a field setting. Zoo Biology 43(1), 55–60.

Forty-seven free-ranging sea turtles (46- Chelonia mydas, 1- Eretmochelys imbricata) were examined via novel use of an endoscopy combined with a rectal enema to obtain large fecal sample volumes. The cloaca was insufflated using an...

Jessica, C.-G., Buendía-González, L., Ruiz-Gómez, M. L. et al. 2024. A minimally invasive procedure for blood extraction from Xenopus laevis allows follow up studies without euthanasia. Journal of Applied Animal Welfare Science 27(1), 192–199.

Blood extraction is extremely important for the development of scientific research; however, the existing methods for amphibian´s blood sampling are invasive, mainly leading to the euthanasia of the animal. Therefore, less intrusive methods that allow...
