GEOFF ORBELL We are starting to see cases of attaching and effacing Escherichia coli (AEEC) in weaned calves this season. This is likely underdiagnosed in New Zealand as no ante-mortem tests are available, and post-mortem examinations often yield false-negative diagnoses due to intestinal autolysis, or lack of submission of a full range of gastrointestinal samples […]

KATHRYN JENKINS We have had a few enquiries recently regarding how to monitor Cushing’s, and how to diagnose Addison’s disease, when Synacthen (for ACTH stimulation testing) is difficult to obtain. So here is some information for you. Monitoring Cushing’s disease (when treated with Vetoryl/Trilostane): To monitor control of Cushing’s (in the absence of ACTH-stimulation testing), […]
BVD testing doesn’t have to be complicated. We have recently simplified our BVD testing options and updated the tests for various ages groups ensuring all details are up to date with the latest guidelines. Calves <35 days old Up until recently, using antigen ELISA testing in animals less than 35 days-old was not recommended due […]
Now that spring has sprung we thought it a timely to remind you of the recommended trace element panels in our current price book. The suggested panels are examples of appropriate analytes for assessing what is happening in the dairy herd. Testing for trace element status is an important part of mineral supplementation plans on […]
