Method Value arrived at by dividing 600 million tons of live weight (see comments section below) by the human population on earth (~7E+9 people) equaling 86kg/person.
Comments "Using these totals and appropriate average body weights, [Smil] calculated that this domesticated zoomass rose from at least 170 Mt of live weight in 1900 – when it was more than four times larger than that of all wild terrestrial mammals – to at least 600 Mt of live weight in the year 2000 when it was approximately 25 times the mass of all wild land mammals (primary source)."
