Pain and animals

Animals and Pain

In addition to the initial question of the right that humans have to impose constraints on animals for the sake of furthering knowledge (Monamy, 1996), experimenters are duty bound to question their methods for assessing the suffering of experimental animals (Veissier, 1999). This questioning is essential on two accounts. On the one hand, as regards ethics, we are straight away aware of the fac...

Nociception and Pain in Animals

Recent evidence has shown that fi sh display aversive behavioral and physiological reactions and a suspension of normal behavior in response to noxious stimuli that cause pain in other animals and humans. In addition to these behavioral responses, scientists have identifi ed a peripheral nociceptive system and recorded specifi c changes in the brain activity of fi sh during noxious stimulation....

Pain in aquatic animals.

Recent developments in the study of pain in animals have demonstrated the potential for pain perception in a variety of wholly aquatic species such as molluscs, crustaceans and fish. This allows us to gain insight into how the ecological pressures and differential life history of living in a watery medium can yield novel data that inform the comparative physiology and evolution of pain. Nocicep...

Recognition and Alleviation of Pain in Animals

Identifying and preventing pain in animals

Animals are routinely subjected to painful procedures, such as tail docking for puppies, castration for piglets, dehorning for dairy calves, and surgery for laboratory rats. Disease and injury, such as tumours in mice and sole ulcers on the feet of dairy cows, may also cause pain. In this paper we describe some of the ways in which the pain that animals experience can be recognized and quantifi...
