StrataGEN development has been under construction for several years, with careful mating and sorting of sires specifically designed to fit the needs of the program. In April 2012 the program was released to combat the rising cost of inbreeding in the dairy industry. StrataGEN uses highly reliable genomic inbreeding data to sort bulls in the Select Sires’ lineup, both proven and genomic young sires, into one of five distinctive genetic lines. These color-coded lines simplify the implementation of StrataGEN on any operation. After consulting with a Select Sires StrataGEN specialist, each herd’s genetic base is identified and a three to five-line rotation is developed based on long-term herd goals and the current inbreeding level of the herd. This one-of-a-kind system can control inbreeding without individual cow matings, making implementation easy.
