I'm fully aware of that, which is why I said "domestically FED and raised". >Also, the feeding animal 10KG to get 1KG looks rather wasteful? Depends heavily on what animal product you are producing. Obviously we won't be eating beef all the time. It also depends on what kind of farmland you have available, and what uses those crops have. Where I am (Wales, UK), the combination of the farmer' lobby and the "Welsh culture and heritage" lobby has meant that largely unprofitable sheep farming has been subsidised, and what should be productive wooded hillside makes lamb that no-one wants. I'm not saying that raising animals is always the best use of land.
