The University of California, Davis Department of Animal Science recently acquired two Holstein bull calves that are genetically polled as a result of gene-editing techniques. Researchers at the university plan to raise the calves to maturity and mate them to multiple Holstein cows to measure the effects of the gene-edited trait on their progeny.
Gene editing is a relatively new application of molecular biology with potential for rapidly introducing a new or modified genetic trait in animals. News reports recently described how researchers at the University of Missouri have used gene editing to produce a line of pigs that are resistant to Porcine Reproductive and Respiratory Syndrome (PRRS).
The gene-edited calves, named Spotigy and Buri, were bred by Recombinetics, a genetic technology company in Minnesota.
