Refinement Database

Database on Refinement of Housing, Husbandry, Care, and Use of Animals in Research

This database, created in 2000, is updated every four months with newly published scientific articles, books, and other publications related to improving or safeguarding the welfare of animals used in research.

Tips for using the database:

  • This landing page displays all of the publications in the database.
  • Use the drop-down menus to filter these publications by Animal Type, Setting, and/or Topic.
  • Clicking on a parent category (e.g., Rodent) will include publications relating to all the items in that category (e.g., Chinchilla, Gerbil, Guinea Pig, etc.).
  • You may also add a keyword to further narrow your search.
  • Please note that at this time, only publications dated 2010 or later (with some exceptions) can be filtered by Animal Type and Topic, and only publications dated 2020 or later (with some exceptions) can be filtered by Setting. Most publications older than 2010 can only be searched by keyword. 
Bellini, L., Schrank, M., Veladiano, I. A. et al. 2023. Retrospective comparison of the effects of laryngeal mask and endotracheal tube on some cardio-respiratory variables in pet rabbits undergoing anaesthesia for elective gonadectomy. Acta Veterinaria Scandinavica 65(1), 10.

Endotracheal intubation in rabbits is challenging and supraglottic airway devices, such as laryngeal masks (LMA), represent an alternative as they are easy to insert, and do not stimulate the larynx requiring therefore a lighter plane...

Kaiser, S., Korte, A., Wistuba, J. et al. 2023. Effects of castration and sterilization on baseline and response levels of cortisol—A case study in male guinea pigs. Frontiers in Veterinary Science 9, 1093157.

An uncontrolled reproduction of animals in human hands should be avoided. To meet this goal, animals are widely castrated, i.e., the gonads are completely removed. Since the gonads are the most important source of sex...

Mauthe von Degerfeld, M., Serpieri, M., Bonaffini, G. et al. 2023. Intranasal atomization of ketamine, medetomidine and butorphanol in pet rabbits using a mucosal atomization device. Animals 13(13), 2076.

A non-invasive method of drug delivery, intranasal atomization, has shown positive results in human medicine and in some animal species. The objective of this study was to evaluate the effects of intranasal atomization, compared to...

Kim, S., Kim, N., Kim, H. et al. 2023. Various endoscopic approaches for removal of proventricular foreign bodies in parrots—Three case reports. Animals 13(24), 3839.

Although the use of incision-free endoscopy for foreign body (FB) removal in dogs and cats has been extensively documented, its application in birds remains limited. Thus, we present the endoscopic removal of gastrointestinal (GI) FBs...

Mandour, A. S., Farag, A., Helal, M. A. Y. et al. 2023. Non-invasive assessment of the intraventricular pressure using novel color M-mode echocardiography in animal studies: Current status and future perspectives in veterinary medicine. Animals 13(15), 2452.

The assessment of diastolic function has received great interest in order to comprehend its crucial role in the pathophysiology of heart failure and for the early identification of cardiac events. Silent changes in the intraventricular...

Torcivia, C., McDonnell, S. 2022. Efficacy of lidocaine topical solution in reducing discomfort reaction of horses to intramuscular vaccination. Animals 12(13), 1659.

Vaccinations via intramuscular injection are a key component of preventative health care in horses. Development of problematic behavioral aversion to injections is quite common. Our clinical impression has been that topical anesthetic applied to injection...

Arena, I., Marliani, G., Sabioni, S. et al. 2021. Assessment of horses’ welfare: Behavioral, hormonal, and husbandry aspects. Journal of Veterinary Behavior 41, 82-90.

Horse practitioners have difficulties with undesirable behaviors exhibited by their horses (Equus caballus), such as cribbing, weaving, or head shaking. It has been suggested that most of behavioral disorders originate from the animals’ attempt to...

Dalla Costa, E., Dai, F., Lecchi, C. et al. 2021. Towards an improved pain assessment in castrated horses using facial expressions (HGS) and circulating miRNAs. Veterinary Record 188(9), e82.

Background: Pain in horses is an emergent welfare concern, and its assessment represents a challenge for equine clinicians. This study aimed at improving pain assessment in horses through a convergent validation of existing tools: we...

Szymczyk, K., Gabriel, S., Zegre Cannon, C. 2020. Removing the blindfold in blind intubation: A summary of tips and tricks for successful rabbit intubation. Laboratory Animal Science Professional 8(5) (September/October), 76-81.

Intubation in rabbits can be difficult due to their unique anatomical features. Large incisors, long narrow oral cavities, thick tongues, and limited mobility of the temporomandibular joint make laryngeal visualization difficult. It is the hope...
