Abstract
A new and effective restraint device was developed for chinchillas that can be used for auditory brain response testing. This device allowed the testing to be repeated more frequently because a lengthy period between successive sessions under anesthesia was not necessary. The reliability and rate of data collection increased. The need for anesthesia was eliminated. The device was simple to use, inexpensive to construct, durable and easily disinfected. The device was constructed of a polyvinyl-chloride (PVC) pipe, a PVC cap, a brass hinge and latch, a brass rod, and steel nuts. A section of pipe formed the body of the restrain, while the cap was modified to accommodate the chinchilla's head. The brass rod was bent into a nose band which kept the head in a natural position. The response of the animals to the use of this restraint was deemed to be excellent. Once in the restraint with the nose positioned in the nose band and the cap latched behind the head, chinchillas were found to sit quietly without movement. Chinchillas remained immobilized for several hours without signs of restlessness, distress, or injury to the nose or the rest of the body. High quality auditory brain response measurements can be obtained without the mortality associated with the use of anesthesia.
