Ogling ostriches is an activity that has been traced to zoo-like collections of animals as far back as 1500 B.C., but in some countries interest in the birds is strictly business. In the past five years, ostriches have captured the fancy of U.S. agricultural entrepreneurs aiming to corner the lucrative leather, feather and gourmet meat markets. Teams of farmers, breeders, nutritionists and veterinarians need to work together to ensure the health of domestic ostrich stock, says retired UC Davis professor Dr. Murray Fowler. Another species with growing herds is the Llama. Nearly wiped out during the Spanish conquest of Central and South America, Llamas became popular in this country nearly two decades ago. On Saturday afternoon, July 27, and Sunday morning, July 28, Fowler will review llama and ostrich health care basics for other veterinarians. Fowler's first professional patient was a camel on the set of Cecil B. DeMille's motion picture set for the "Ten Commandments." Since then, the zoological veterinary medical expert has written what is believed to be the only comprehensive book on llama medicine, as well as numerous other publications on nearly every facet of zoological medicine.
