Although accurate population estimates aren't readily available (I can only find charts indicating trends, not numbers per se), one would assume that the wild populations are far greater than commercial livestock, given that much of the US and Europe are actually populated with people. One simply doesn't find vast herds of cattle like you do in Africa--not any more, anyway, i.e., buffalo, antelope, etc. This information seems to apply only to nations that raise commercial livestock, disregarding the enormous populations of natural ruminents that exist in the African continent (wildebeest, hartebeest, impala, etc.).
