Dutch certification.
Pig Progress, June 2003: 11
The Animal Health Service (AHS) chose the use of Ivomec Injection (two injections 14 days apart) as the standard protocol to be used in herds to be certified mange-free. Only 1.5% of herds failed certification - half of the failures were due to import of mange-positive pigs; one fourth due to incorrect or omitted dosing of some pigs; and one fourth to unknown causes. Since 2000 other methods have been accepted by AHS, including use of Ivomec Premix. Use of Dectomax by injection has also been used by AHS, but inexplicable failures have been observed. Starting 8 months after eradication, a certfication as mange-free requires: no clinical signs of mange; no use of miticides since eradication; scratching index <0.4; negative ear scrapings; and any introductions to the herd must be mange-free pigs on mange-free trucks.
