In this episode, Brad shares his fall updates from western Minnesota before diving into a detailed discussion on genomic testing in dairy herds. Drawing on his experiences from recent farm visits in South Dakota and ongoing University of Minnesota research projects, he explores how producers are using genomics and whether the investment pays off.
Brad explains that while some herds use genomic testing solely to decide which animals to breed to beef, he believes the technology’s value lies much deeper — in improving herd genetics, managing inbreeding, verifying parentage, and advancing traits like health, fertility, and production components. He outlines the major testing companies (Neogen, Zoetis, and Genetic Visions), their costs (around $37–$42 per animal), and the kinds of data producers can expect from each, including A2 status, horned/polled traits, and wellness indices.
The episode also includes two case studies:
- A small grazing herd where genomic testing clarified breed composition, revealed unknown sires, and identified A2 status across mixed-breed animals.
- A university research herd exploring polled genetics and crossbred performance, where Brad questions how well current evaluations reflect the true genetic potential of crossbreds like Normande and Montbéliarde crosses.
Brad closes by summarizing the practical ways to use genomic information — from strategic breeding and heifer selection to developing niche markets like A2 milk products. His key takeaway: genomic testing can be a powerful tool for herd improvement, but it’s only worth the cost when used strategically rather than as a simple breeding filter.
