News is breaking that Chinese scientists have created genetically modified (GM) cattle using human genes to produce "human-like" milk in a bid to make cow's milk more nutritious. The intention is to produce it on an industrial scale to replace formula milk and breast milk, when normal breast feeding is either not possible or undesirable. The Telegraph newspaper reports that scientists at the State Key Laboratories for AgroBiotechnology at the China Agricultural University have successfully introduced human genes into 300 dairy cows to produce what they call "human-like" cow milk. It is well known that human breast milk contains key nutrients that can help to boost the immune system of babies and reduce the risk of infections. The scientists wanted to find a way to produce an alternative to human breast milk and formula milk on an industrial scale, with the eventual aim of getting this GM "human-like" cow's milk on supermarket shelves.

For most of human history, our relationship with cattle has been about the foods they produce: milk, meat and cheese. Today, a new bovine "product" has captured our interest and may indeed affect the future production of the others. This new product is gas. Cow burps are the most recent in the list of accused contributors to global warming from the livestock sector. However, a simple measurement of methane production does not tell the whole story. A new report by the Soil Association reevaluates greenhouse gas production in agriculture, taking into account the grazing system - not just the "end product." This controversy erupted in recent years as figures emerged about agriculture's contribution to greenhouse gas emissions. As we discussed in our November 16, 2009 blog, "Beware of Bad Science," grassfed cattle actually produce fewer emissions than those finished in feedlots, simply because of the carbon sequestration in their pasture-based systems. The new Soil Association report confirms this and adds new data to support the position.
