Identification Systems
Animal Science 1
Competency 11.0
Differentiate identification systems used in the animal industry.
Objectives
11.01: Define identification systems including branding, ear notching, and tagging that are used in the animal industry.11.02: Select animals according to a given identification system.
Branding
Uses a metal instrument to burn or to freeze a mark on the animalThe original use was to show ownership NOT individual animal identification numbers
Branding
Provides a permanent method of identifying animals.
Animals are usually branded prior to weaning.
The Beef Improvement Federation recommends the use of a lettering system to represent the year of birth. This reduces the number of items that are
branded on the animal. Provides uniformity for all breeds. Example: 2013= A, 2014=B, 2015=C, etc.
Ear Tagging
Uses special pliers to attach plastic pieces with numbers on themEasy to read from front view but is less permanent than some systems
Ear Tagging
Tags are made of plastic or metal. The same lettering system representing the year of birth can also be used on ear tags.
Ear Notching
Uses a special notching tool to cut little “V” notches on animal’s ears
Tattooing

Tattooing
Uses a special tool to put inked numbers in ears, lips or other locationsIt is permanent, simple and relatively painless to use
Tattooing
Utilizes a lettering system to represent the year of birth. More difficult to read than other systems.
Animal Identification
Use the information in the references to learn what the numbering systems mean and how to read the codes.
Angle Brand System
Uses two square with one rotated an eighth of a turn “O” on the brand is horizontal double
bars =
“1” is vertical double bars II
Ear Notching
View animal by standing behind it to determine the left and right ears.
Ear Notching
Right Ear Notches indicate litter number
Ear Notching
Left Ear Notches indicate individual number
Ear Notching
What the notches mean: Notch on bottom of ear near the
head: 1 Notch on bottom near tip of ear: 3 Notch on the tip of ear: 81 Notch on top near tip: 9 Notch on top near head: 27
Ear Notching
The left ear only has notches in the 1, 3, and 9 spots. Two notches can be made at each of these places.27 and 81 are not needed for individual numbers in the litter.
