Various What Is Genomic & Parentage Testing for Dairy Cattle?
By Various
Last reviewed: December 2025
Genomic and parentage testing uses DNA analysis to determine genetic merit, confirm parentage, and identify genetic conditions in dairy cattle.
Overview
Genomic testing has revolutionized dairy cattle selection by enabling genetic merit predictions from a young age. Unlike traditional breeding values that require production records, genomic predictions use DNA markers to estimate potential.
A tissue sample - typically from an ear notch or tail hair - is analyzed for thousands of genetic markers. These markers are compared to reference populations to predict performance for production, health, fertility, and type traits.
Parentage testing confirms the sire and dam of each animal, correcting pedigree errors that affect breeding decisions. Many genomic tests include parentage verification automatically.
Snapshot
Description: Genomic and parentage testing uses DNA analysis to determine genetic merit, confirm parentage, and identify genetic conditions in dairy cattle.
Who It's For: Dairy farms seeking to make breeding and culling decisions based on genetic information rather than just pedigree.
What It Does Best: Provides accurate predictions of genetic potential and definitive parentage confirmation from a simple tissue sample.
Why It Matters: Genomic information enables better selection decisions, faster genetic progress, and reduced inbreeding.

Buying Considerations
Important factors to consider when evaluating What Is Genomic & Parentage Testing for Dairy Cattle?:
- Testing Laboratory Accreditation: Choose ISAG-certified labs ensuring quality standards and international recognition. Verify lab participates in proficiency testing programs with >99.5% accuracy rates.
- Trait Panel Comprehensiveness: Evaluate panels covering production, fertility, health, and conformation traits. Premium panels include 60+ traits while basic panels cover 20-30 core traits affecting profitability.
- Sample Collection Method: Hair samples cost $5-8 more than tissue samples but offer easier collection. Nasal swabs provide middle-ground option with good DNA quality and moderate cost.
- Turnaround Time Requirements: Standard processing takes 10-14 days while rush services (3-5 days) cost 50-75% premium. Consider breeding calendar timing when selecting service speed.
- Data Integration Capabilities: Ensure results integrate with existing herd management software. API connectivity and standardized data formats reduce manual entry and improve decision-making workflow.
