A jugular bleeding technique in rabbits

When studying pharmacokinetics in rabbits, researchers must often take multiple blood samples from conscious rabbits. Researchers usually collect these samples via the auricular vein, typically through a port or an indwelling catheter. The authors have developed an easy and efficient...

Clinical biochemistry parameters in C57BL/6J mice after blood collection from the submandibular vein and retroorbital plexus

Collection of blood from the submandibular vein allows simple and rapid processing of many animals without anesthesia and facilitates rapid recovery with no signs of pain and discomfort in the mice. Here we compared the submandibular vein and retroorbital plexus...

Quality of blood samples from the saphenous vein compared with the tail vein during multiple blood sampling of mice

A large number of methods for obtaining blood from mice have been published. In our facility, saphenous venepuncture is considered the method of choice for bleeding mice and is believed to have a number of welfare advantages when performed correctly....

Comparative analysis of blood sampling techniques in the rat

Blood sampling is one of the most common procedures performed on laboratory animals as part of scientific research. As an ongoing commitment, our institution has identified a need to improve the current blood sampling method in rats from both a...

Glucocorticoid metabolites in rabbit faeces – Influence of environmental enrichment and cage size

The concentration of glucocorticoid metabolites (GCM) in rabbit faeces has been suggested as a non-invasive indicator of stress. In the present study, GCM concentrations were measured in faeces of fattening rabbits kept in groups of eight, at seven different stocking...

The choice of bedding substrate, route of blood collection, and method of glucose determination all affect fasting blood glucose levels in C57BL/6 mice

This study compared 4 bedding substrates (corncob, paper, hardwood chip, and wire-bottomed cage inserts) and 2 routes of blood collection (lateral tail vein and retroorbital sinus) in 6 male C57BL/6NCrl mice. Mice were maintained with ad libitum food and water...

Training rhesus macaques for conscious blood sampling in six steps

Step 1 Gently squeeze the animal about halfway towards you. Hold the animal in place for about 1 to 2 seconds.We use this time to talk to the animal calmly in a gentle voice. When the time is up, release...

Training time required to collect a variety of biological samples using primarily positive reinforcement training methods

Positive reinforcement training (PRT) methods can be applied to gain the voluntary cooperation of laboratory primates with the collection of biological samples. Information will be provided on training techniques used and the amount of training time required for various sample...

Operant conditioning with laboratory beagles

There is increased regulatory emphasis on positive reinforcement training for husbandry, research procedures, and restraint devices. We practice acclimation, association, and positive reinforcement training with our beagle colony with goals to reduce stress for dogs and improve efficiency for personnel....

Validation of a refined technique for taking repeated blood samples from juvenile and adult mice

Repeated blood sampling from laboratory animals is desirable in certain experimental designs and also for reducing the number of animals used in research. Biochemical methods for analysing blood samples require only small blood volumes to be collected (typically 20-40 μL)....
