A livestock farmer is expected to establish the identity of an animal as soon as the animal is born or some days after birth. A lot of farmers have ignored animal identification which is very important. Giving names to farm animals may serve the purpose to an extent for a small heard, but may not be feasible for a large herd or farm with many animals. So it is important to put some sort of identification marks on each animal present on a farm. Some of the importance of identification includes:
- It makes record keeping easy for a livestock farmer or animal breeder.
- It makes treatment or culling of sick or unproductive animals easy.
- It makes it easy for a breeder to select replacement stock for the next breeding season.
There are various methods that can be used to identify an animal. These include ear tagging, ear tattooing, number tagging, branding and ear notching.
1. Ear tagging
Ear tags are metals pieces that have letters or numbers engraved on them. They are of two types and they include; self-piercing tags and the ones that require that a hole is made in the ear of the animal using an ear punch. Normally, these tags are inserted within one-third of the way out from the base of the animal’s ear and the upper edge of the animal’s ear with the number at the top.
2. Ear Tattooing
Ear tattooing is another method of putting an identification mark on animals with light coloured ears. It involves punching several small holes with a die (specifically meant for tattooing) in the form of letters or numbers through the skin on the inside of the animal’s ear and they are then filled with tattoo ink. This should form a permanent mark if done properly. The standard is to start marking with “001” till it reaches “999”. The demerit/disadvantage of using this identification method is that there is a need for catching the animals and cleaning the inside of the ear before the identification marks can be read.
3. Number tagging
Some farmers prefer using large metal tags that can be seen and read at a distance rather than using ear tagging or tattooing identification method on their animals. Number tagging involves fastening metal tags to neck chains and putting the chain around the neck of each animal. The disadvantage of this method is that these metal tags may get lost.
Branding is the most common identification method used in animal husbandry. It is normally done when the animals are very young or before they are weaned. This method involves gentle press of a heated number or symbol on the body of the animal. This causes partial burning of the skin tissue and results in a permanent scar showing the number or symbol.
Branding can also be done using a cold stamping iron. Here, a branding liquid is used and the stamp is dipped in the branding liquid and applied on the animal’s body the same way the hot iron is done. The wound takes longer to heal up under this type of branding.
The disadvantage of branding method is that a permanent damage is caused to the branded animal’s skin, thus reducing the value of its skin or hide. I always recommend the lower part of the animal’s thigh as the best place for branding as that part is of very low value.
5. Ear Notching
This is an easy method of identifying animals and it involves making notches cut in the ears of the animals. A notch represents a number based on its location (on the bottom, top or end of the ear as well as the ear it is in). This method is commonly used on pigs, rabbits, goats and sheep.
For poultry birds, you can use light aluminum wing tags carrying either individual or group numbers. This is done a day after hatching, and a separate numbered or coloured leg band may be used when the birds are matured.
