Beware Typhoid Mary in your herd. She may not be showing signs of infection, but could be carrying and shedding Salmonella Dublin, a bacterium that can be transmitted from lactating cows to calves.

There are discussions in dairy industries in many countries about whether it should be an explicit aim to increase longevity. Some assert that retaining cows for longer lactations or more years contributes to sustainability because fewer replacement animals would be needed, reducing the environmental costs of these non-productive animals.

Health events are undesirable events in dairy farms and, in my opinion, are one of the biggest challenges the dairy industry has been facing. Although the incidence of some specific diseases – such as milk fever or clinical ketosis – has decreased in the last 20 years or so, the overall percentage of animals experiencing one or more diseases in the first 60 days after calving hasn’t changed.

Like the speedometer, the dry-off list may include cows that are milking more than expected, and it might be necessary to pump the brakes hard to dry them off successfully. Or, like the blind spot, life happens, holidays and time off intervene, and suddenly, there are more cows on the dry-off list than expected. Automated milking systems and milking system software have some options for managing cows going into the dry period.

From pre-fresh to post-fresh, data from automated monitoring technology empowers dairies to act earlier, manage smarter and achieve stronger returns – one transition cow at a time.

Your cows may not have a crystal ball, but monitoring technology used during the dry period may provide valuable information that can be used to predict the risk of potential health disorders that could affect lactation performance post-calving. Considering dry cows often are “out of sight and out of mind,” monitoring technology can fill the gap by keeping tabs on them 24-7.
