An estimated 487,200 tonnes of genetically modified material, by weight, was used in animal feed in Australia in 2006-07, according to an Australian report. This represented about 5% of all feed grains by weight used in that year, with proportions varying across the livestock industries, depending on the feed mix used. It is estimated the chicken-meat industry on average used the largest volume of GM feed grain in 2006-07, followed by the egg and dairy industries.
