Heifer Management Blueprints: Understanding Your Genomic Results

After submitting DNA samples for genomic testing, there comes the daunting task of understanding and utilizing the results. Genomic results are typically organized and sent out in an electronic file. Results are reported 1 – 2 months after the sample is submitted. The spreadsheet will summarize all traits which are reported as Genomic Predicted Transmitting […]

Heifer Management Blueprints: Dairy Heifer Genomics

Genomic testing for cattle, which became commercially available in 2009, predicts traits that are pertinent to dairy operations, such as milk yield, longevity, and fertility. Most artificial insemination (A.I.) companies have been genomic testing bulls for some time, but reasonably low cost genomic tests are now available to test dairy calves and heifers. Genomic testing […]
