Racing Pigeon AB Pigeon Detection

TL;DR: AB pigeons (substituted birds) are a cheating tactic in pigeon racing. This guide covers how DNA comparison identifies substitution and safeguards fair competition.

“AB pigeon” is a hated cheating method — using two similar-looking pigeons to share one identity, one resting while the other races. AB pigeon detection uses DNA identification to make substitution impossible.

What Is an AB Pigeon?

An “AB pigeon” lets multiple birds share the same leg-ring identity:

• Bird A races while Bird B rests
• Frequent swapping keeps the racing bird fresh
• Similar appearance defeats visual checks

How DNA Identification Works

Sanshi Bio uses 58 loci for individual identification:

1. Build a gene profile before the race (gene ID card)
2. Re-sample and test after the race
3. Compare the two genetic profiles
4. Mismatch proves substitution

DNA is each pigeon’s inborn, unforgeable identity.

FAQ

Does AB pigeon detection require a pre-race profile?

Yes. Establish a 58-locus profile before the race, then re-sample winners for comparison.

How is AB-pigeon testing done?

Sample and profile racers pre-race, then re-sample winners post-race — a genotype mismatch indicates substitution.

Can leg rings prevent AB pigeons?

Rings can be swapped or duplicated. Genetic identity based on DNA is unforgeable and far more reliable.

Key Takeaways

1. AB pigeon is substitution fraud — replacing the racing bird with a same-name, same-ring double.
2. DNA comparison catches it — genetic identity cannot be forged.
3. Pre-race identity verification — sample before basketing, compare after the race.
4. Works with gene ID cards — one builds identity, the other verifies it.
5. Protects race fairness — eliminates ‘look-alike’ substitution.
