Since genomic testing became commercially available in 2008, more than 8 million U.S. dairy animals have been genotyped for dozens of key genetic traits related to milk production and quality, feed efficiency, reproductive viability and cow health. By optimizing genetics within their herds, dairy producers have successfully bred new generations of cows to produce more milk, butterfat and protein with fewer resources.
The sustainability aspect of dairy genomics is largely an untold story . . . each year, the U.S. dairy industry needs fewer cows to produce the same amount of milk which translates to less methane production, a smaller carbon footprint and less feed required for each unit of milk.” – Corey Geiger
