I suppose that the thought of culling any wild animal doesn't have much appeal, and, like absenta, I also am confused by the amount of conflicting information on the subject, but a good point was made on Country File recently - with the rarer breed herds that farmers are trying to build up, every beast that has to be destroyed diminishes the chances of the blood line succeeding. Farmers get compensation for the animals they lose, but to lose a good breeding bull, or a cow in calf, perhaps even cows in calf, is a tragedy to a breeding programme that no one can compensate a farmer for. I don't know a lot about cattle - or badgers - but, to me, that makes sense of why farmers are so anxious to try anything to get TB eradicated.
