What Canadian Cows Are Telling Us about Footbaths

By Karin Orsel on

The University of Calgary Lameness Research Team has been hard at work studying the use and effectiveness of footbaths on Alberta dairies.
While there is progress to be made in proper usage, the good news is: Results confirm that footbaths are an effective tool in decreasing the prevalence of digital dermatitis (DD).

How to Detect DD in Pregnant Heifers

By Steve Mason on

Researchers at the University of Wisconsin reported that heifers with pre-partum digital dermatitis (DD) had lower milk production, poorer conception to first service, longer days open and were more likely to have multiple cases of DD. Those researchers recommended that a DD control program should be a priority for pregnant heifers. But before a control program can be implemented, a reliable method of detecting DD in these animals is required. At the 2016 Western Canadian Dairy Seminar, University of Calgary graduate student Casey Jacobs described how she used ‘pen walks’ to detect DD in pre-calf heifers.
