Other mammals commonly found in research are guinea pigs, rabbits, hamsters, and farm animals such as pigs and sheep. Most of these animals are specifically bred and raised for research.Researchers choose the species that best parallels the biology of what they want to study.For example, sheep provide a model to study osteoarthritis, a breakdown of cartilage that occurs as people age, causing pain and inflammation in the joints.pecies such as dogs, cats, and non-human primates account for less than 1% of all mammals in research.
