Neogen’s new Igenity Dairy Heifer Program offers the dairy cattle industry an unprecedented level of information on the genetic potential of replacement dairy heifers. The new genetic profile uses hair follicles to produce DNA test results that provide information on a heifer’s potential in key traits. Those traits are performance and health traits such as net merit, pregnancy rate, productive life in months and somatic cell score; and yield traits, such as the animal’s milk in fat pounds, fat percentage, protein pounds, and protein percentage; and numerous calving and type traits. The test can be performed soon after a calf is born, and is another tool in the decision-making process for breeding and heifer selection.
The Igenity Dairy Heifer Program uses Neogen’s own GeneSeek Genomic Profiler, or GGP, with more than 19,000 single nucleotide polymorphisms (SNPs), to create the industry’s most comprehensive genomic result. This result is then analyzed by the Center for Dairy Cattle Breeding and the USDA-AIPL to produce genomic-enhanced predicted transmitting ability estimates, or GE-PTA’s.
In addition to the genetic markers from the GGP for use by the USDA-AIPL in the estimation of genetic merit for key production traits, the program provides access to additional information on key results for health, such as freedom from lethal abnormalities, milk composition including casein and lactoglobulin, plus horn poll status. Plus, from a single DNA sample, you can also get a BVD test, coat color test, horn poll test, A2 beta casein test, and even a parentage test completed.
