A new genetic test is going to increase milk production in cows and yield big profits.
While it may take years before widespread genetic testing changes humanity, animals are experiencing a difference today. According to Forbes, a single genetic test for breeding dairy cattle has almost completely replaced older pedigree tests in less than two years. Developed by Curtis Van Tessell at the USDA and performed by Illumina, this test costs only $250, replacing the previous system’s $50,000 price tag! The cheaper testing allows smaller dairy farmers to enter into the profitable business of selling cattle eggs and sperm. Using genetic testing, milk producers predict that the annual increase in US milk production will double to 5%. We’re talking about millions of dollars of increased profit in the United States alone. Van Tessell’s new test demonstrates that the age of widespread genetic evaluation has already started.
When it comes to human genetic testing, Illumina is one of the biggest names in the business. It and competitors like Complete Genomics are aiming to bring whole genome sequencing into the price range of most individuals. Right now, more affordable genetic evaluation can focus on key genes in human DNA. These single nucleotide polymorphisms (SNPs) are cheaper to test – companies like 23andMe use them exclusively to great avail. In Van Tessell’s test, SNP tests are used to keep track of 38,000 key differences that the USDA team discovered were important in dairy cattle breeding. One wonders how whole genome sequencing will affect animal husbandry. The bovine genome was recently mapped in 2009. Could we see even more profitable breeding? Maybe greater acceptance of germline genetic engineering? The reverse also could be interesting: how will attitudes about human genome testing change when genetic evaluation becomes a staple on the farm?
