It's actually an interesting discussion although probably not the right thread to discuss it on. We are not Organic in the official, inspected by the soil association way, but all our growing is done without harmful chemicals. Our animals however are a different matter. Partly there is no financial incentive to fork out masses of money for inspections but I decided early on that if I feel an animal needs a particular medicine then I'm going to give it rather than wait for permission from a 'body' somewhere down in England. We do use antibiotics if required, although we don't give them prophylactically. We do use wormers as required, following the recommendations of the Mordun Institute, which is the Scottish livestock research body. We do use anti-flystrike products (crovect).
I have seen a sheep keeper who thought he was doing the right thing by not using anti-flystrike products and his sheep were crawling with maggots. We eventually persuaded him that vaseline is not enough, especially when he couldn't catch the animals anyway. Whether that was because he was 'organic' or not I don't know, but 'Organic' should not be treated as meaning 'don't care' - it is a well-thought out and successful way of growing and raising food for human consumption, if its tenets are followed carefully - or so I believe.....
It would be interesting to have the opinion of someone who does raise their animals in a truly 'Organic' way (I hate the word 'organic' because most things on earth are fairly much organic with a slightly different meaning). I'm sure there are methods of good husbandry whereby livestock can be raised without any harmful medications or chemically treated feeds, on mixed farms with an holistic approach, and I would like to learn more about how that is done.
I commented tizaala because you made a huge generalisation - which may or may not be true.....
