Question/Problem:

What is that white mark on a mustang’s neck?

 Answer:   

Mustangs are all freeze-branded along the left side of their necks upon capture.  This painless procedure uses liquid nitrogen to permanently alter the color of the horse’s hair and is less traumatic than traditional hot-iron branding.  A mustang’s brand includes multiple pieces of information: the registering organization (e.g. the US government), the horse’s date of birth, and his identification number. Within the identification code is a sequence corresponding to his state of origin.
