Mad Cow Disease?

Let's guess; near Area 51?

ALBUQUERQUE, N.M. (AP) -- One of Orlando Romero's calves has a leg up on the other 25 calves born within the last two weeks on his ranch east of Tucumcari. The calf was born with an extra leg, with two hooves, growing from its back.

....The week-old calf's extra leg does not touch the ground. It is attached to the calf's back between the shoulder blades, and hangs to its right side.

The branch-like growth is the only major difference between the copper-colored calf and the rest of the herd, said Shane Jennings, a neighbor who first spotted the heifer.

....Milton Thomas, professor of beef cattle physiology and genetics at New Mexico State University in Las Cruces....said extra body parts are a freak occurrence.

....Thomas said extra appendages result of a cellular mix up during the replication of genetic material in early embryo development. Certain cells will develop into tissues such as muscles or organs, but some receive skewed signals and grow into unnecessary parts.
