The Drost Project Visual Guides from Veterinarian Maarten Drost at the University of Florida provides stunning visual guides to theriogenology, which is the study of animal reproduction. The species the Drost Project focuses on presently are cow (bovine), buffalo (bubaline), sheep (ovine), pig (porcine), and horse (equine). A guide to dog (canine) reproduction is under development as well. The visual guides include photos from theriogenologists around the world, and the sections devoted to each animal are well laid out and easy to use. Each section provides photos for multiple topics, including "Female Reproductive System", "Male Reproductive System", "Accidents of Gestation", "Abortion", "Reproductive Management", and "Teratology" (birth defects). Additionally, a printable version of each photo is offered for educational use. Be forewarned that the photos on this site are very graphic and may be disturbing to a visitor unfamiliar with this area of veterinary medicine. Regardless, the site is a valuable one, particularly to those persons in veterinary science.
