Evaluating Your Seedstock Herd
Every calf crop represents genetic progress in your seedstock operation, building on the best your operation has to offer. Take your selection decisions to the next level through genomic technology.
AGI’s suite of test options are used to establish GE-EPDs to measure genetic merit for breeding stock, and can also determine parentage or test for genetic conditions — important capabilities in the management of your herd.
Genomic testing technology has evolved since genomic profile results were first incorporated into Angus EPDs in 2010.
The hundreds of thousands of HD tests submitted by Angus breeders to date have helped improve and
regularly calibrate genomics programs to interpret markers, increase accuracy
and allow for the development of low-density (LD) tests, as well as the
GeneMax suite of tests for commercial users of Angus genetics.
The availability of HD and LD tests gives Angus cattle producers several
options in genomic testing, available through AGI’s partnering labs GeneSeek
and Zoetis and accessible through AAA Login
Determining which is right for your operation depends on several factors.
High density (HD)
Most advanced genomic testing option
Regardless of provider, genotype results are equivalent in their contributions to calculating GE-EPDs.
Ideal for high-impact parents who are likely to have progeny tested using LD tests (ex: highly used AI sires)
Low density (LD)
More affordable with nearly the same level of accuracy as HD tests
Through imputation, results are indistinguishable from HD tests (the correlation between HD and LD genomic predictions is .99).
Makes testing more animals feasible and is suitable for most animals
Note: Selecting which test and company is in an individual decision, and AGI may choose to upgrade certain samples that were initially
LD-tested to HD tests to maintain the accuracy of genomics programs.
