We are enjoying a better quality of life and the subsequent development of new medicines and treatments through animal research. Animal testing is necessary in some studies because some animals have same physiological and genetic behavior as humans. Some people believe that animal have full right of life so animal experimentation should be ended but others believe that although animal experimentation is wrong but we can’t neglect the useful information derived from animal testing helping for advancing medical science . Animals must be used for research in an ethical framework because they can feel the pain and pleasure. One view is if animal doesn’t have anatomy and capabilities as humans only then it can be used for research process. The middle ground is animal experiments should be carried out only if there is no alternative . There should be best possible treatment for animals used in study .All the information derived from the study must be useful. There should be proper use of anesthesia and there should be proper training for handling animals in laboratory.
The development of alternative methods like human robot and methods for engineering tissue samples are intended to replaces the animal animal testing as it is reduces the time and cost and number of animal used in research.
