Swine Identification 



The following are APHIS-approved means of swine identification (see table 6 for 

 swine breed codes): 



• Official eartags when used on any swine. 



• USDA backtags when used on swine moving to slaughter. 



• Official swine tattoos when used on swine moving to slaughter if the use of the 

 official swine tattoo has been requested by a user or the State animal health official 

 and APHIS authorizes its use in writing based on a determination that the tattoo 

 will be retained and visible on the carcass of the swine after slaughter so as to 

 provide identification of the swine. 



• Tattoos of at least four characters when used on swine moving to slaughter except 

 sows and boars. 



• Ear notching when used on any swine if the ear notching has been recorded in the 

 book of record of a purebred registry association. 



• Tattoos on the ear or inner tlank ot an\' swine it the tattoos have been recorded in 

 the book of record of a swine registry association. 



• For slaughter swine and feeder swine, an eartag or tattoo bearing the Premises 

 Identification Number assigned by the State animal health official to the premises 

 on which the swine originated.

Equine Identification 



With the current high level of interest within the horse industry regarding equine 

 census estimates and potential disease movement, new methods for equine 

 identification are rapidly being researched and developed. Many breed registries 

 are either contemplating change or are in the process of changing the methods 

 by which they identify horses. For that reason, specific breed requirements for 

 identification are not listed here. Instead, this manual describes equine identification 

 technologies currently available, in production in the United States, or in the late 

 stages of development. You should consider multiple technologies when you are
