Low-milk-fat syndrome, commonly known as milk fat depression (MFD), has been studied for approximately 170 years. Many hypotheses have been evaluated in order to explain the biological mechanisms by which nutrition could modulate milk fat percentage.

In order to achieve any goal in life, the first step is to believe it is possible. Perhaps your herd is averaging 26,000 or 28,000 pounds of milk. That’s nothing to shake your head at.

Historically high cull cow values, along with increased scrutiny for residues in milk and meat, should have already advanced your decision process for mastitis treatment by now.

A valid veterinary-client-patient-relationship requires that every dairy owner and manager regularly reviews all of the treatment protocols with their attending veterinarian and includes plans to decide which cases are worth treating.

Dairy farmers work from sunup to sundown to establish a herd of high-producing cows, but no farmer is thrilled with the risks and consequences that linger in the shadows.

As farmers, we have to face the facts: High-producing cows are at a significantly greater risk of contracting a mastitis infection.

Just when you think you’ve done everything you can to grow healthy, robust heifers and avoid health challenges such as respiratory disease and scours, there’s more: heifer mastitis.

It can appear in your heifer pens earlier than you think. Exposure to mastitis-causing pathogens happens at several points in heifers’ lives, from birth to calving.

Often, we hear things like, “Perhaps you should change your treatment; maybe the ‘bugs’ on your farm are building up a resistance to what you are using.”

I’ve heard arguments that this could happen and arguments that this is not a concern for dairy farmers. But has anyone ever suggested this about teat dip disinfectants? I don’t think I’ve heard that discussion too many times, if ever.

Mastitis is a complicated and costly problem for the dairy farmer. No simple solutions are available for its prevention. Some aspects are well understood and documented in scientific literature.

Others are controversial and opinions are often presented as facts. However, from the dairy farm perspective, two simple product mandates are required – simplicity in use and cost.

Organic dairy production in the U.S. is regulated by the U.S. Department of Agriculture (USDA) via its National Organic Program (NOP). The NOP was established with the passage of the Organic Foods Production Act (OFPA) by Congress in 1990.
