From the article:

While the team said that this was the first instance of gene insertion into cattle using a single nicking Cas9, it was far from the first application of genome editing to livestock, or even cows. In May 2016, researchers led by Minnesota-based gene editing firm Recombinetics reported substituting an allele in dairy cattle to eliminate horns, using transcription activator-like effector nucleases (TALENs) to induce HDR. And last fall, another team of scientists from Northwest A&F University reported editing cashmere goats using CRISPR to produce more of the fine hairs used in wool production.
