An MIT Technology Review article published in September states that scientists think they are on the verge of creating new strains of livestock using DNA technology. The science may improve both meat and milk production, while calming consumer concerns.
Genome editing may change the way people view genetically modified livestock, Lisa Henderson reported for The Collegian. The method uses genes from animals that are already in the food supply. Jennifer Bormann, associate professor of animal breeding and genetics at Kansas State University, said that this is the same process that has been used with plants for a long time. She also said that they could do the same thing without using this technology, but it would take a very long time.
“We could do the same thing with traditional breeding by crossing and backcrossing repeatedly to introgress the gene of interest,” Bormann said. “It would just take many generations of crossing and many years.”
