  1. Ear Notching in Swine

  2. Reasons for ear notching • A permanent ID system • Individual identity for all animals • Inexpensive means of identification • Enables producers to keep an accurate set of records

  3. When to ear notch • Task is much easier if pigs can be notched when their tails are docked, or at 1-3 days old • If you allow pigs to become large (100 lbs), the task can become considerably demanding mentally and physically.

  4. Equipment needed • Notchers • Disinfectant to dip the notchers in • Spraying larger pigs with a wound dressing can be helpful http://www.neogen.com/7500-01.htm

  5. Safety • Notching equipment must be kept clean at all times • Must be cleaned with a clean tooth brush between litters and then dipped in fresh surgical spirit or alcohol • Fresh alcohol must be used each day the notching equipment is in operation

  6. Safety • After use the notching equipment should be cleaned in hot soapy water using the tooth brush to clean • The notching equipment should then be placed in surgical spirit for 10 minutes • Store dry within a plastic bag to stop any dust getting on them • Do not sterilize by boiling as this will blunt the cutting surface

  7. Safety • If notching ears on older or larger pigs, it may be necessary to house them in separate pens until the notches heal. • Pen mates not notched maybe attracted to the bloody notches and start ear biting.

  8. Safety • Avoid making notches too shallow, as they may become hard to read or possibly heal shut. • Leave at least 1/4 inch between notches • Avoid making notches too close to the head. • Putting the notches in the right locations

  9. Principles of the system • Refer to right and left from the pig's perspective. • Same as yours if you are standing in back of the pig • Reversed if you face the pig • The pig's right ear is called the litter ear. • When a sow has a litter, all pigs in the litter receive identical notches on the right ear.

  10. Principles of the system • The left ear in pigs is like the first name for humans, every pig in the litter gets his own unique notch in the left ear. http://www.boarsemen.com/boarpen/earpart1.htm

  11. Principles of the system • Instead of names though, pigs are identified by numbers. • 1, 3, 9, 27 quadrants, and an 81 may be notched at the very tip of the ear • Two notches are allowed in each quadrant http://www.boarsemen.com/boarpen/earpart1.htm

  12. Principles of the system • All the numbers in the left ear are added to identify the individual pig within that litter. • All numbers in the right ear are added to make the litter number. • With this system every number from 1 through 161 can be created on each ear.

  13. Except for the 81 notch, there can be two notches at each of the four locations 9 9 27 9 81 27 9 3 3 3 3 1 1 1 1 Right Ear Litter Number Left Ear Pig Number

  14. Principles of the System • Minimum of one notch on each ear • Maximum of 9 notches on an ear • This shows a pig with the maximum on the litter ear and the minimum on the pig ear. http://www.boarsemen.com/boarpen/earpart1.htm

  15. Example #1 • The right ear is 1+1+3+3+9+9+27+27+81 which equals 161. • This pig came from litter #161 on your farm. • The left ear adds up to 1. • This was the first pig notched in that litter. First pig in litter # 161 http://www.boarsemen.com/boarpen/earpart1.htm

  16. Example #1 • This pig's notch is written "161-1" • This pig's notch is pronounced "one sixty one dash one" http://www.boarsemen.com/boarpen/earpart1.htm

  17. Example #2 http://www.boarsemen.com/boarpen/earpart2.htm

  18. What are this pig’s numbers? http://www.boarsemen.com/boarpen/earpart2.htm

  19. Answers • 82-9 • The litter ear adds up to 82 • Individual, or pig ear, is 9 http://www.boarsemen.com/boarpen/earpart2.htm
