Qué es un certificado de ADN de aves y por qué es importante

En Laboratorio de pruebas de ADN de aves SENO, we frequently provide what’s known as a bird DNA certificate — a genetic “passport” that uniquely identifies an individual bird based on its DNA. Much like human fingerprinting, these certificates document multiple genetic markers across a bird’s genome, offering unambiguous proof of identity and lineage.

1. What Is a Bird DNA Certificate?

A ADN de aves certificate is a formal document that includes a tested bird’s genetic profile from specific DNA markers — typically Single Nucleotide Polymorphisms (SNPs) o Short Tandem Repeats (STRs). These genomic loci are carefully chosen because they vary between individuals, making each certificate as unique as a human fingerprint.

1.1 Why It Matters

• Individual Identification: Even visually similar birds, such as siblings or same-colored parrots, can be differentiated by their DNA.

• Global Standardization: Using loci recognized by international bodies like the International Society of Animal Genetics (ISAG), bird DNA certificates serve as legally and scientifically valid identification documents.

For example, common markers:

• Gen CHD (avian sexing): used to distinctly identify males versus females via Z/W chromosome differentiation.

• Pigeon STR panel: including locus PG1–PG7, plus CHD, is accepted in parentage and individual identity testing.

• Feather SNP panels: target specific nucleotide differences across the genome for precise individualization.

According to Animal Genetics, DNA profiles using STR microsatellites are “99.99% effective in detecting parentage and individual identity

2. How Do We Make a Bird DNA Certificate at SENO?

Producing a reliable bird DNA certificate involves three key steps:

2.1 Genotyping DNA Loci: SNP vs STR

• STR (Microsatellite) Method

• Repeats of short DNA motifs (e.g., “CA” repeats) in variable lengths.

• Multiplex PCR amplifies several markers simultaneously.

• Gene-welfare bodies like ISAG endorse STR loci for avian parentage and identity tests.

• SNP-Based Profiling

• Single letter changes in the DNA code at hundreds of sites.

• Offers high-throughput, standardized, and digitally comparable data.

• Increasingly adopted across livestock and wildlife genetics.

2.2 Sample Requirements

We accept:

• Plumas (root present): ~10–20 feathers.

• Blood samples: via EDTA-coated capillaries.

• Buccal/swab samples, or other tissues.

Animal Genetics recommends ~10 plucked feathers to generate accurate profiles.

2.3 Certificate Content

Each bird DNA certificate includes:

1. Unique Sample ID / QR Code

2. Genetic Marker Data (allele sizes or SNP calls across 10–20 loci)

3. Laboratory & Testing Date

4. Methodology specification: STR or SNP

5. Analytical Confidence Score (>99% certainty)

DNABird, for example, includes QR-verified certificates to support traceability.

3. Why Make a Bird DNA Certificate?

3.1 Parentage Testing

Bird breeders use DNA certificates to determine precise lineage. SENO’s tests are 99 %+ accurate when parents’ samples are available. Studies on pigeon STR panels reflect global standards.

3.2 Scientific Research

• In conservation biology, SNP panels have revealed population structure in Saker falcon across Eurasia using as few as 36 exonic SNPs nature.com.

• Genetic mark–recapture (DNA tagging) aids non-invasive monitoring in wild bird studies.

3.3 Authentication in Trade

• Racing pigeons: DNA certificates verify parentage and authenticity in competitive events.

• Exotic parrots: Certificates validate ownership, pedigree, and legality, especially for species regulated under CITES.

• Stolen Birds: Legal usage of DNA certificates to recover and identify lost or stolen avian individuals.

Example: Animal Genetics offers DNA data banking for stolen birds gendika.com+13avian2.animalgenetics.com+13icar.org+13.

4. How Much Does It Cost?

At SENO, our pricing is transparent and competitive:

Compared internationally:

• Animal Genetics (USA): ~$50 per STR panel (includes parentage).

• Gendika (EU): €45 (~$48) for a feather-based parentage test and certificate.

• DNABird (Canada): ~$17.50 for sex with QR certificate(basic sexing, not parentage).

SENO’s cost advantage: SNP-based certificates at $60 provide higher data resolution at lower cost than competitors, all while ensuring accuracy.

5. Science & Credibility Behind Our Method

• SNP vs STR

• STR: Highly polymorphic, standard for parentage & identity

• SNP: More reproducible, genome-wide coverage. Proven effectiveness in avian population studies, like Exonic vs Intronic SNP work on Saker falcon

• Certification Standards

• We align with ISAG y ICAR guidelines for STR and SNP certification in animal genetics.

• Turnaround & Accuracy

• Typical processing time: 5–7 business days

• Confidence level: >99.9% for identity, >99% for parentage

6. Real Cases from SENO

• Racing Pigeon Club

Members upload the feather/tracheal swab. We provide:

• STR panel confirming lineage to the prized racing lineage.

• SNP certificate used in international sales and registry.

• Parrot Rescue

A rescued African grey parrot, lacking documentation, received an SNP certificate, enabling its legal rehoming and screening.

• Conservation Project

Working with NGOs, we issued DNA certificates for wild kestrel chicks to monitor individual lifespan and survival.
