Genomic testing
Find out how genomic testing affects sire indexes and what it means for selection in your herd.
Genomic testing analyses DNA obtained from tissue, hair or blood to predict an animal’s genetic potential for production, health, fertility and feed efficiency. It helps identify genetically superior heifers early, verify parentage and detect recessive genetic defects, accelerating genetic progress in the herd.
Benefits
Early selection
Identify an animal's potential before it joins the milking herd.
Accuracy
Obtain reliability comparable to performance data from several dozen offspring.
Health and disease screening
Test for genetic defects and traits associated with disease resistance.
Targeted mating
Breed your highest-value heifers with sexed semen, and use beef sire semen for lower-ranking animals.
