Animals that require a test in the 30 days after movement will be restricted immediately to the herd into which they have moved. This herd has 30 days to carry out a test on these animals. If after 30 days, the animals have not been tested, the herd that received them will be restricted. Sale of calves under six weeks of age and the purchase in of animals will be permitted. If after another 60 days, the animals have still not been tested, the whole herd will be scheduled for a TB test. If the moved in animal at any point is slaughtered, the restriction will be lifted, except where the herd has been listed for a full test. This allows the opportunity for cull cows to be purchased, fed and slaughtered without incurring the cost of testing.
