Pigs are really common in biomedical testing. They are physically a similar size and weight to humans. They also reach maturity in about 6 months. Much cheaper to raise than primates, and more likely to get approval for testing. My friends in biomed grad school named one of theirs cyber pig because it has about 30 different experiments ran on it before it was killed, and afterwards it was portioned out for further tests.
