Procedure
Methods of Identification
- Ear Tagging
- Plastic or metal tags are attached to the ear of the pig
- Each tag carries a unique number or code
- Most common and widely used method in commercial farming
- Easy to read from a distance
- Ear Notching
- A permanent method where notches are cut into specific positions of the ear
- Each position represents a number following a standard notching system
- Commonly used for litter and individual identification in piglets
- Should be done within the first few days of birth
- Tattooing
- Ink is injected into the inner ear or skin using a tattooing instrument
- Provides a permanent and tamper-proof form of identification
- Commonly required for purebred and show animals
- Numbers or letters are used as identification codes
Steps in the Identification Process
- Restrain the pig properly to avoid injury to the animal and handler
- Select the appropriate identification method based on age and purpose
- Clean and disinfect the area (ear or skin) before applying identification
- Apply the tag, notch, tattoo, or microchip as per standard procedure
- Disinfect the area after the procedure to prevent infection
- Record the identification number along with the following details:
- Date of birth
- Breed
- Sex
- Litter number
- Dam and sire information
- Weight at birth
- Update records regularly with health, feeding, and growth data
- Inspect identification marks/tags periodically to ensure they are intact and readable
Important Points to Remember
- Identification should be done as early as possible, ideally within the first 3–7 days of birth
- Always use sterile equipment to prevent the spread of disease
- Replacement tags should be applied immediately if a tag is lost
- All identification records should be kept in a register or digital database
