The first herd test is in - now what ?At the first herd test, this acts as a rough estimate on the efficacy of your dry cow and the effectiveness of early season management. At the second and subsequent herd tests, this indicates how well infection spread is controlled in the herd.
You might want to treat some cows to reduce the BMSCC. Before treating any cows, ensure that they are still high (i.e. have not self-cured since the test) by using the RMT paddle to look for gelling and sub-clinical infection. A weak reaction in only one quarter means reassess her in a few days. She may self-cure. Consider treating quarters with strong reactions to the RMT. Extended courses of your recommended antibiotics work best. Discuss treatment selection and WHPs with your vet.
