Animal testing, also known as animal experimentation, animal research, and in vivo testing, is the use of non-human animals, such as model organisms, in experiments that seek to control the variables that affect the behavior or biological system under study. This approach can be contrasted with field studies in which animals are observed in ...
Fortrea primate-testing lab, Vienna, Virginia, 2004–05. Most of the NHPs used are one of three species of macaques, accounting for 79% of all primates used in research in the UK, and 63% of all federally funded research grants for projects using primates in the U.S. [25] Lesser numbers of marmosets, tamarins, spider monkeys, owl monkeys, vervet monkeys, squirrel monkeys, and baboons are used ...
Transgenic animal production consists of injecting each construct into 300–350 eggs, typically representing three days' work. Twenty to fifty mice will normally be born from this number of injected eggs. These animals are screened for the presence of the transgene by a polymerase chain reaction genotyping assay. The number of transgenic ...
In 2010, a new EU directive was published on the protection of animals used for scientific purposes, repealing the old directive 86/609/EEC on January 1, 2013, with the exception of Article 13 (statistical information on the use of animals in experiments) which has been repealed on May 10, 2013.

However, the lack of an adaptive immune system and the simplicity of its organs prevent C. elegans from being used in medical research such as vaccine development. [3] The fly D. melanogaster is the most widely used animal in genetic studies. This comes from the simplicity of breeding and housing the flies, which allows large numbers to be used ...
One of Pavlov’s dogs with a saliva-catch container and tube surgically implanted in its muzzle, Pavlov Museum, 2005. The history of animal testing goes back to the writings of the Ancient Greeks in the 4th and 3rd centuries BCE, with Aristotle (384–322 BCE) and Erasistratus (304–258 BCE) one of the first documented to perform experiments on nonhuman animals.

Winders, an animal-testing opponent who has criticized Neuralink, said the inspector general has primarily focused in recent years on dog fighting and cockfighting actions when applying the Animal ...
Refinement: use of methods that alleviate or minimize potential pain, suffering, distress, or lasting harm and improve welfare for the animals used. The 3Rs have a broader scope than simply encouraging alternatives to animal testing, but aim to improve animal welfare and scientific quality where the use of animals cannot be avoided. In many ...
