Comparison of updated Angus GE-EPD tests

As you may know, both Zoetis and GeneSEEK have updated their genomic tests.

Zoetis still uses about 50,000 SNPs, but have now trained their data set with more animal records and genotypes. The genetic correlations for the Zoetis test range from 0.38 to 0.73. See this Angus Journal article for more information.

GeneSeek now use about 80,000 SNPs in its genomic test. The genetic correlations for the GeneSeek test range from 0.60 to 0.70 for most traits, except milk which is at about 0.4 and calving ease direct which is at 0.34. See this explanation from the American Angus Association.

So, the accuracy differences appear to be pretty small.

Both tests cost $75. If you add genetic abnormality tests, such as AM, NH, or CA, to the Zoetis test, you pay $23.00 per test. If you add an the same genetic abnormality tests to the GeneSeek test, you pay $8.00 per test.
