Mooooove over CRISPR chickens, pigs and goats. The powerful gene-editing tool is another step closer to transforming the barnyard.
Researchers at China’s Northwest Agriculture and Forestry University tailored a CRISPR/Cas 9 technique to give cloned dairy cows a leg up against the bacteria behind bovine tuberculosis (Mycobacterium bovis), a threat to cows in many parts of the world. Last year, another group used TALENs, an older gene-editing technology, to create two cows without horns, but this is the first time scientists have reported using CRISPR to insert a gene in cattle.
