Veterinary genomics & companion-animal diagnostics

01Overview and value chain

Markers: [EC: Veterinary Genomics & Direct-to-Consumer Biotech | OECD: Biotech & Health | Regulator: FDA (USA), EMA (EU), NMPA (China)]

Veterinary genomics and companion-animal diagnostics applies human-grade high-throughput genotyping and sequencing to pet dogs and cats, turning a cheek-swab sample into a screen of 250+ inherited disease risks, a breed-ancestry breakdown across 350+ breeds, and a trait panel covering coat, body size and blood group. The technology stack rests on three pillars: SNP microarray genotyping on custom Illumina BeadChips packing 230,000+ markers per dog, targeted next-generation sequencing (NGS), and GWAS-grade bioinformatic pipelines aligned to the CanFam4 reference genome. The market is concentrated and fast-moving: the two US leaders alone have collectively tested more than 6 million animals, turnaround sits at 2–4 weeks, and a 2026 $160 million deal saw the world’s largest animal-health company absorb a global network of five genomics laboratories across five countries.

The key directions of veterinary genomics and companion-animal diagnostics are:

1. Genetic health-risk screening (Genetic Health Risks): detection of carrier status for 250+ inherited conditions — MDR1/ABCB1 drug sensitivity in herding breeds, HCM in Maine Coons, PKD in Persians, PRA blindness — reported as clear, carrier or at-risk.
2. Breed ancestry identification (Breed Ancestry): percentage decomposition of mixed-breed animals against reference databases of 350–365+ recognised breeds, varieties and wild canids, at 99% marker accuracy.
3. Trait and physical-feature analysis (Traits): coat colour and length, shed factor, predicted adult weight, and blood group from a single genotype.
4. Oral microbiome and predictive wellness (Predictive Wellness): sequencing of the feline oral microbiome linked to gingivitis risk, extending genetics into a prognostic companion-animal health score.

Value chain levels

Cross-cutting technologies of the sector:

• Illumina Infinium BeadChip (SNP Microarray): 230,000+ silicon beads each carrying a 50-mer probe, read by two-channel laser fluorescence on the iScan.

02US

The United States is the world’s largest commercial market for veterinary genetics, concentrating the technology giants and integrating DNA testing into the largest national veterinary-clinic chains.

Embark & Wisdom Panel duopoly, Zoetis consolidation, clinical integration

• Embark Veterinary leadership: founded 2015 in partnership with the Cornell University College of Veterinary Medicine, Embark runs custom Illumina BeadChips at 230,000+ markers, screens 270+ health risks across 350+ breeds, and has tested more than 1 million dogs at 99% breed-identification accuracy.
• Wisdom Panel and Mars Petcare: owned by Mars via Kinship Partners and headquartered in Vancouver WA, Wisdom Panel operates the industry’s largest database at 5 million+ animals across 50+ countries, screening 265+ conditions and 51 traits with results in 2–3 weeks.
• Zoetis consolidation: the world’s largest animal-health company (NYSE: ZTS) acquired cat-genomics pioneer Basepaws in 2022, and on 2 March 2026 signed a $160 million deal for Neogen’s animal-genomics business — five laboratories across the US, Brazil, Australia, China and the UK serving 120+ countries.

03CN

China is building a domestic companion-animal genomics sector on top of the world’s largest sequencing capacity, driven by a young generation of cat owners in tier-1 cities.

National sequencing houses, university genetics R&D, Shenzhen DTC startups

• Sequencing-house pet services: the country’s major genomic-service providers have launched consumer sub-brands offering low-cost pet DNA testing built on domestic NGS platforms rather than imported SNP chips.
• University genetics research: animal-genetics departments at institutions such as China Agricultural University run large studies to identify disease loci specific to endemic Asian cat and dog breeds.
• Shenzhen DTC cluster: a dense cluster of direct-to-consumer biotech startups offers point-of-care PCR and LAMP-based genetic tests for veterinary clinics, complementing chip-based screening with rapid in-clinic panels.

04EU

The European Union foregrounds the ethics of purebred-animal breeding, weaving mandatory DNA testing into the rules of kennel and feline associations.

Kennel Club mandatory screening, accredited labs, Helsinki biobank R&D

• UK Kennel Club mandatory screening: The Kennel Club requires DNA testing for inherited disease before admitting certain breeds to registered breeding, excluding mutation carriers from reproduction.
• Accredited reference laboratories: Genomia (Czech Republic) is a leading ISO 17025-accredited central-European pet and livestock DNA centre, developing custom PCR panels for breeders across dogs, cats, horses and birds.
• Helsinki canine biobank: the University of Helsinki runs one of the world’s largest canine genetic biobanks, identifying candidate genes for epilepsy, anxiety and skeletal dysplasia in northern breeds.

05Leading companies and research institutes

06Tech stack and innovations

The veterinary DNA-testing stack is built on solid-phase hybridisation genotyping, automated wet-lab robotics and statistical bioinformatics.

1. Cheek-swab DNA isolation (Saliva DNA Isolation):
   • collection tubes hold lysis-preserving buffer that stabilises DNA at room temperature for up to six months before the sample reaches the lab.
   • Hamilton Microlab STAR robots dose protease and magnetic silica Dynabeads into each well, wash under chaotropic salt and elute clean genomic DNA.
2. SNP microarray hybridisation (Illumina Infinium BeadChip):
   • the sample is whole-genome-amplified, fragmented and hybridised onto a custom BeadChip carrying 230,000+ 50-mer probes for 20 hours at 48 °C.
   • single-base extension with fluorescent ddNTPs is read by the two-channel Illumina iScan laser, calling homozygous-wild-type, heterozygous or homozygous-mutant genotypes at every marker.
3. Bioinformatic association and GWAS (Bioinformatic Association):
   • NGS reads are aligned to the CanFam4 (dog) or Felis_catus_9.0 (cat) reference assemblies and variants are called with GATK HaplotypeCaller.
   • quality-filtered variants are matched against curated disease-association databases and combined into polygenic risk scores for multifactorial traits.

Stage 1: Sample receipt and barcode registration

A saliva kit mailed by the owner arrives at the robotic lab; an operator scans the 12-digit 2D tube barcode, which syncs instantly to the owner’s LIMS account, and the tube is racked onto the automated deck.

Stage 2: Hamilton robotic DNA extraction

A Hamilton Microlab STAR unscrews the 96-tube rack, doses lysis buffer with proteinase K, incubates at 56 °C for 20 minutes, then adds magnetic silica Dynabeads; after magnetic washes the robot elutes clean genomic DNA, verified on a Qubit fluorometer to ≥10 ng/µL at A260/280 ≥1.8.

Stage 3: BeadChip hybridisation

The purified DNA is whole-genome-amplified, enzymatically fragmented and dispensed onto a custom canine BeadChip of 230,000+ silicon beads; the chip hybridises for 20 hours at 48 °C so pet DNA binds its complementary probes, then is washed to strip non-hybridised material.

Stage 4: Enzymatic extension and iScan readout

The chip moves to a staining chamber where single-base extension adds fluorescent ddNTPs; after drying, the Illumina iScan laser excites each bead and reads red versus green fluorescence, converting the signal into a raw IDAT genotype file.

Stage 5: Bioinformatic variant calling

The IDAT files are imported by Illumina GenomeStudio for genotype clustering, then a GATK/PLINK pipeline aligns calls to the CanFam4 reference and flags pathogenic variants such as the ABCB1 drug-sensitivity mutation.

Stage 6: LIMS verification and veterinary DNA passport

Called variants are matched against clinical databases in the LIMS; any high-risk call is manually confirmed by an on-duty geneticist before the system generates the interactive owner-portal report and a PDF veterinary passport with diet and screening recommendations, and emails the owner.
