Targeted attacks on large-scale intensive dairy systems for their contribution to greenhouse gas emissions are unfounded, according to farm business consultant, Graeme Surtees speaking at the 2010 British Cattle Breeders Conference, Telford. "A recent study showed higher-yileding cows delivered a lower carbon footprint for each litre of milk than low yileders. "For example, a cow producing 5000 litres a year creates a total of 434kg carbon equivalent/litre compared with 290kg/litre for a cow producing 9000 litres a year. Intensive feedlot systems in Wisconsin produce an average 1.38kg of carbon a litre compared with 1.62kg of carbon on New Zealand extensive grazing systems.Freshlogic pty ltd 2010. Release February 8
