Genomic study proves profitability, methane reduction

28 minutes

Genetics in the dairy industry are making big strides. Project leaders Lauren Brey and Dr. Dan Weigel share about a collaborative project between Edge Dairy Farmer Cooperative, Farmers for Sustainable Food, Zoetis, and 8 aligned farms, showed how focusing on genetic improvement correlates to not only lifetime profitability but reductions in methane intensity, antibiotic usage and feed use on the farm. Dairy Stream host Joanna Guza dives into the topics below with Lauren and Dan:

1:50: How the project got started

2:43: How the farms were selected

5:04: Dairy Wellness Profit Index and how it was used

7:55: Process of collecting and analyzing the data

9:40: The study had 43 percent reduction in antibiotic usage

13:38: The study had 23 percent reduction in the number of replacement heifers

15:00: The study had 15.8 metrics tons of methane reduced per 1,000-cow herd

16:48: The study had a decrease in feed used

19:52: If farms want to participate, what is the timeline and ROI

22:51: How does the research impact the future of sustainable food

25:00: What’s next for the future of research and genetics

Dr. Dan Weigel

Dan grew up in Iowa on the family farm (Weigeline Holsteins) and graduated from Iowa State University with a BS in Dairy Science. He received both his MS and PhD from Virginia Tech, with his dissertation focusing on the prediction of genetic merit for lifetime profitability in Holsteins. Before joining the R&D group of Zoetis (formerly Pfizer Animal Health) in 1995, Dr. Weigel served as a post-doctoral fellow at the University of Guelph working on the implementation of Multiple Across Country Evaluations (MACE) for conformation traits of Holstein sires. Dr. Weigel’s current role with Zoetis is in Outcomes Research and he also remains active as a breeder of dairy cattle.
