Euthanasia

Assessment of pain associated with the injection of sodium pentobarbital in laboratory mice (Mus musculus)

The AVMA Guidelines for the Euthanasia of Animals considers injection of barbiturates to be an acceptable method of euthanasia in rodents but states there is a potential for pain when administered intraperitoneally. This study examined the potential for pain in...

The role of emotional contagion in the distress exhibited by grouped mice exposed to CO2

The 2013 AVMA Guidelines for the Euthanasia of Animals recommends a chamber volume displacement rate of 10% to 30% per minute (v/min) when euthanizing small laboratory rodents with CO2. Group euthanasia of mice is a common practice, and grouping strangers...

Disaster planning for animals in hazardous agent containment units

Disaster response planning for laboratory animal facilities is a time- and personnel-intensive undertaking. This article outlines numerous considerations in formulating a plan for disaster response in a high containment animal unit. The planning process is discussed around a set of...

Anesthesia and euthanasia of brine shrimp (Artemia franciscana)

Invertebrates are often overlooked as laboratory animals, yet they are commonly used in toxicology, developmental, cellular and molecular biology, and radiation studies with euthanasia as an endpoint. Little is known regarding appropriate euthanasia methods for invertebrate species, particularly for Artemia....

Humanely ending the life of animals: Research priorities to identify alternatives to carbon dioxide

The use of carbon dioxide (CO2) for stunning and killing animals is considered to compromise welfare due to air hunger, anxiety, fear, and pain. Despite decades of research, no alternatives have so far been found that provide a safe and...

Physiological and behavioral indicators to measure crustacean welfare

The purpose of this project was to determine how neural circuits were affected during warming by examining sensory neurons, the neuromuscular junction, and the cardiac function and behavior of the commercially important crustacean species, the red swamp crayfish (Procambarus clarkii)....

Efficacy of a novel mechanical cervical dislocation device in comparison to manual cervical dislocation in layer chickens

The main objective of this study was to assess the efficacy of mechanical cervical dislocation using the Koechner Euthanasia Device Model C (KED) in comparison to manual cervical dislocation in layer chickens. Laying hens and/or roosters in three different age...

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...

Evaluation of euthanasia of sheep with intravenous saturated salt solutions to enable the collection of whole, intact brains

Captive bolts or firearms are unsuitable for euthanasia of livestock when an intact brain is required for diagnostics. Injectable barbiturates can be used, but this method carries risk of poisoning animals eating the carcase. Intravenous saturated salt solutions have been...

Refinement of intraperitoneal injection of sodium pentobarbital for euthanasia in laboratory rats (Rattus norvegicus)

Background: The Canadian Council on Animal Care and American Veterinary Medical Association classify intraperitoneal (IP) pentobarbital as an acceptable euthanasia method in rats. However, national guidelines do not exist for a recommended dose or volume and IP euthanasia has been...
