The discovery by New Zealand scientists, reported in the trade magazine Chemistry & Industry, says that Marge and other cows like her have genes that make their milk naturally low in saturated fats. According to a BBC news report, Marge was discovered in 2001 during a screening of milk of a whole bunch of cows by the biotech company ViaLactia. The same genetic tendency turned up in some of Marge's young, raising the tantalizing possibility of breeding a whole fat-free herd. Now the scientists say they plan to have one by 2011.
