Use
In laboratory animal husbandry, there is a huge demand for animals that have been kept in disease free conditions and housed in barrier units such as Individually Ventilated Cages. This is very important because when animals are used for scientific research, particularly drug-related research, the animals must provide accurate and valid results. Using an animal that is ill may cause the severity limit to be exceeded. If the animal already has a disease and then undergoes experimentation of a substance that also produces effects on the animals health, it could potentially worsen the effects of the agent being tested causing the animal to experience more suffering than necessary. The animals may produce false results which may prove vital at a later stage, e.g., in drug trials on humans. Not only that, the experiment will have to be performed again and the previous animals would have ended up being killed. Special caging systems are often used alongside many other barriers to keep unwanted materials out of range of the animals.

Famous quotes containing the word use:
“... it is use, and use alone, which leads one of us, tolerably trained to recognize any criterion of grace or any sense of the fitness of things, to tolerate ... the styles of dress to which we are more or less conforming every day of our lives. Fifty years hence they will seem to us as uncultivated as the nose-rings of the Hottentot seem today.”
—Elizabeth Stuart Phelps (1844–1911)
