Our herd is tested for CL, CAE, and Johnes once a year. We utilize an accredited lab (WADDL) so we are assured that our results are accurate. We test goats over 1 year of age. Goats under one year will carry the doe’s immunology and therefore, are not appropriate to test.
WADDL provides a nice description of the diseases we are concerned with. You can read more here.
Here is a copy of our 2018 results.
2019 tests were ran via Sage Labs and tested clean.
