One thing deterring some consumers from turning to milk as a beverage is lactose content. For lactose-intolerant individuals, a calf born at Inner Mongolia Agricultural University may offer a degree of hope. Named “Lakes,” she is a genetically modified calf that is expected to produce low-lactose milk in a couple of years.
Lab professor Zhang Li extracted fetus fibroblasts from a Holstein that was 45 days pregnant and genetically engineered the fetus by transplanting a lactose dissolution enzyme into the cell, reports Xinhua news service.
Zhang explains, “The enzyme can dissolve lactose—the main sugar found in dairy products—into galactose or glucose to ease digestive disorders among lactose-intolerant people.” Nearly 60% of Chinese are believed to be lactose-intolerant.
