To compare: One neolithic human of the very first phase (4000 bc, where 500kg grain was harvested per ha = 3-4-fold of the seed) required about 0.5 ha (1.2 acres). One hunter/gatherer in optimal woodland with optimal hunting strategies required about 1000 ha (for 250-320 kg meat, long term sustainable). Quite efficient, to keep these cows on the 11 acres, because so on the area of one h/g you could keep 225 cows, instead of only 4-5 big game animals, which would be available there naturally. Do you know: Is this grassland only? If it's grassland, is it fertilized (as usual in all Central Europe)? For many years cow-life is this? I mean, are the cows grain fed after some time (to really gain weight) ? Or is it necessary to grow some grain crop on this area which is then fed to the cows? Amadeus
