Emma was born on August 30 weighing in at a healthy 75 lbs. She was cloned using the same technology that resulted in Millie, UT’s first bovine clone and the United States’ first Jersey clone produced using an adult somatic cell.

Emma was cloned to research the genetic basis of mastitis resistance among dairy cattle. Mastitis infections cause billions of dollars annually in lost revenue to the dairy industry due to lost production, investments in animal care, and in milk that has to be discarded. Her genetic twin,Tennessee Maid (Tenn. Khan DFF Maid), is a cow known to be susceptible to mastitis.

“Emma” is an acronym that stands for UT’s efforts at experimental manipulation for mastitis abatement.

On April 15, 2002, at approximately 9 months of age, Emma was euthanized by veterinarians in the UT College of Veterinary Medicine. The young cow was suffering from severe complications associated with rumenitis, a digestive disorder well known among dairy cattle and other ruminants.
