StrataGEN is a unique, sequential breeding system that offers optimal use of genomic insights to help dairy producers achieve individual breeding goals while also minimizing inbreeding.

Select Sires introduced StrataGEN in April of 2012. StrataGEN uses genomic insights to categorize both daughter‐proven sires and genomic young sires into one of five unique genetic lines, based on common traits they’ve inherited from their ancestors, as confirmed by individual genomic testing.

StrataGEN™Each line is identified with a single color‐ orange, blue, green, yellow or red, for easy understanding and implementation into any dairy breeding program. Inbreeding and the potential financial losses it causes, is a real problem in dairy operations today.

With the intensive use of genomics now being applied to sire selection, the risk of inbreeding is even greater.

StrataGEN™Research has indicated that for each one percent inbreeding increase in a herd, performance is impacted by: ‐24 Lifetime NM$, +.36 days of age at first calving, ‐13 days Productive Life, ‐790 pounds lifetime milk production, ‐25 pounds lifetime protein production and +.26 month first calving interval. All of these issues add up to have a significant impact to a dairy producer’s bottom line.

Select Sires has been developing StrataGEN since genomic testing was perfected. For several years and even multiple generations, Select has been carefully mating and sorting bulls specifically designed to fit each of the five lines.
