But slaughterhouses have come to realize they can demand more for the animals, so biology instructors may be forced to rely on dissection stand-ins. The Scientist reported that there are two main reasons why prices have increased so dramatically. Since I've spent considerable time developing a lab manual of the pig and computer tutorials, I'm holding my breath on this one. David Brown, a professor of biology at Point Loma Nazarene University, cites yet another advantage to dissecting fetal pigs. We have considered other animals as alternatives but have found student sympathy and consequent acceptance of fetal pigs to be much to our advantage.
Few students have pet pigs.
Cats, birds, dogs, fish and others seem to have more animal rights problems.
