Experimental model

Experimental model (or animal disease model)

Animals that are employed to model the development and progression of diseases, and to test new treatments before they are given to humans, are used in experimental modelling. Animals with transplanted human cancers or other tissues are called xenograft models.

Training animals to take their own medication is one method to reduce stress under experimental conditions. This monkey has been given a syringe with juice carrying the medication and he will take the juice voluntarily. Although we can force most of our experimental animals to do what we want, it is always better to have their cooperation. The level of stress on the animals, technicians, and investigators is less when force is not needed.
