AnimalIdentification Systems

Identification Systems

• Branding cattle

• Ear Tagging

cattle

goats

• Tattooing cattle

rabbits



Branding

Used mainly for cattle

Two types Freeze Branding

Hot Iron Branding

Uses a metal instrument to burn or freeze a mark onthe animal’s hide

Damage to hides is a problem with all types of branding.

Originally used to show ownership

Ear Tagging

Use special instruments Easy to read from the front view

Not permanent

Can be lost or removed



Ear Tagging and tattooing



Tattooing

Uses a special tool to put inked numbers in ananimal’s skin

Most commonly found in the ear

Can be used on the lips or other locations

Permanent

Simple and relatively painless Hard to read from a distance



Tatooing



Tatooing and tagging



Numbering SystemsSystem One

This system utilizes a three or four digit number for each animal.The first number represents the year of birth. The remaining numbers represent the

individual animal’s own number.

921 or 9021

9 = year of birth, '99

21 or 021 = individual animal’s numberWith this system all calves born in

1999 or in the '99 would have numbers starting with 9

(i.e., 901, 902, 903, etc.).

Following this system, 2000 calf numbers would start at 021 (or 0021) and 2001 calves



System Two

System two is similar to the first

system. The animal number is branded above the

year of birth or written with a dash or a slash.In this example 21 is the animal number and 9 is

the year of birth.

21

9 or 21/9 or 21-9



System Three

It is similar to the first two systems. The

main difference is the year of birth is

represented by a letter.

J21, J021, 21J or 021J

J represents year of birth, '99

21 or 021 represents the calf ’s number



System Four

This system assigns consecutive numbers to ani-

mals in the herd. When 99 or 999 or a

predetermined number is reached, then the

numbers can be restarted at 1.



System Five

Mostly on the right and left thigh or ear of animal

Right thigh/ear—birth serial number+first

letter of farm name Left thigh/ear---last no. of year (right side) +

quarter (left side)

E.g 42---- 2002---4th quarter



Electronic markers

Electronic markers are available whereby a smallmicro-chip is implanted at a convenient site e.g. nextto the tail head or in the thick neck muscles.

An instrument which must be pointed at the implantsite from a relatively short distance, is used to readthe signalled identity number of the animal

emanating from the microchip. Where this system is available it is very useful, but

microchips can become faulty.



DNA finger printing

With modern technology, the genetic make-up of an animalcan be recorded. In cattle, these images are unique and can beused to identify animals by sending a sample of blood orother appropriate tissue to a laboratory with the required

equipment.

Although not a technique which can be used for routineidentification, it can be used for example where an animal isslaughtered and the thieves leave the animal’s skin behind,taking only some or all of the meat.

With DNA finger printing the relevant meat can be identifiedas belonging to the skin and its identifying brand.
