7 Ways CRISPR Is Being Used That Have Nothing to Do with Human DNA

2. Livestock Enhancement - Creating Disease-Resistant Animals

The livestock industry is experiencing a transformation through CRISPR applications that focus on improving animal health and productivity without compromising welfare. Scientists are editing genes in cattle, pigs, and poultry to create natural resistance to devastating diseases that cost billions in economic losses annually. One groundbreaking example involves editing pig genes to make them resistant to Porcine Reproductive and Respiratory Syndrome (PRRS), a virus that causes significant mortality and economic damage in swine populations globally. Researchers have also successfully created cattle with enhanced resistance to bovine tuberculosis and mastitis, reducing the need for antibiotics and improving overall herd health. Beyond disease resistance, CRISPR is being used to enhance desirable traits such as improved meat quality, increased milk production, and better feed conversion efficiency. These genetic modifications can help reduce the environmental footprint of livestock farming by creating animals that require fewer resources while producing higher yields. The technology also enables the development of livestock adapted to different climates, potentially allowing farming in regions previously unsuitable for certain animals, thereby improving global food security and reducing pressure on existing agricultural lands.
