Fur chewing and other abnormal repetitive behaviors in chinchillas (Chinchilla lanigera), under commercial fur-farming conditions

Fur chewing is a behavioral disorder frequently reported in chinchillas kept for fur-farming purposes. Rodents kept in barren cages usually develop some form of abnormal repetitive behavior, which can indicate a past or present welfare problem. Fur chewing may not...

Alternatives to carbon dioxide—Taking responsibility for humanely ending the life of animals

Carbon dioxide (CO2) is commonly used to kill rodents. However, a large body of research has now established that CO2 is aversive to them. A multidisciplinary symposium organized by the Swiss Federal Food Safety and Veterinary Office discussed the drawbacks...

Anesthetic and postanesthetic effects of alfaxalone–butorphanol compared with dexmedetomidine–ketamine in chinchillas (Chinchilla lanigera)

Effective and safe anesthetic protocols are required for a variety of surgical and diagnostic procedures in chinchillas. Alfaxalone, a new anesthetic agent in the United States, can be administered intramuscularly and subcutaneously and is therefore potentially useful as an anesthetic...

Analgesic efficacy and safety of buprenorphine in chinchillas (Chinchilla lanigera)

Buprenorphine is routinely used in chinchillas at reported doses of 0.01 to 0.1 mg/kg IM or SC. However, these dose recommendations are based on anecdotal reports or extrapolation from studies in other species. Therefore, the purpose of this study was...

Analgesic efficacy and safety of hydromorphone in chinchillas (Chinchilla lanigera)

Limited information is available regarding the efficacy of opioid analgesics in chinchillas. Here we sought to evaluate the analgesic efficacy and safety of hydromorphone in chinchillas. In a randomized, controlled, blind, complete crossover design, hydromorphone was administered at 0.5, 1,...

Relationship of thyroid and adrenal function to fur-chewing in the chinchilla

The fur-chewing chinchillas showed increased thyroid activity (P < 0·5), increased adrenalcortical function (P < 0·05) and decreased rectal temperature (P < 0·01). This study suggested that increased endocrine activity could be due to the loss of insulation over the...

Sound and its significance for laboratory animals

Several methods of varying accuracy have been used to assess what sounds small laboratory animals such as rodents are capable of hearing. Most rodents can detect sounds from 1000 Hz (the frequency of the Greenwich Time Signal) up to 100000...

Stress-induced Cushing’s syndrome in fur-chewing chinchillas

One of the most serious problems in the chinchilla industry is 'fur-chewing', when the chinchilla bites off areas of its own or some other animal's fur. The condition generally develops in both genders at the age of 6-8 months. In...
