In the world of dairy farming, maximizing milk quality and cow comfort is paramount. Dr. Andy Johnson, famously known as ‘The Udder Doctor,’ has been at the forefront of this mission. With experience ranging from small farms with 20 cows to large-scale operations with 22,000 cows, Dr. Johnson’s insights have reached dairies across 30 countries and 47 states.
Throughout his career, he has championed the “100 Award,” an accolade granted to dairies that maintain an average of 100 lbs. of milk production under a somatic cell count of 100,000. Remarkably, in the past 15 years, more than 40 dairies have earned this distinction, with 75% achieving it in just the last five years. According to Dr. Johnson, a farm’s cell count is a reflection of its management practices, encompassing factors like housing, milking routines, and equipment maintenance.
Prioritizing Cow Comfort and Hygiene
A key point emphasized by Dr. Johnson is the critical role of environmental cleanliness in preventing infections.
“Cows in a dirty environment will have a higher risk to new infections. Keep cows clean, dry, and comfortable 24 hours a day,” he advises. This was a central message shared with over 300 attendees at the 2025 National Mastitis Council Annual Meeting in Charlotte, N.C.
Dr. Johnson also underscores the importance of a consistent milking routine and proper training for milkers.
“Do not just train one time,” he insists. “Continual training is a must.” This ongoing education is vital for maintaining high standards of milk quality.
Optimizing Milking Routine
Focusing on the milking procedure, Dr. Johnson outlines an ideal routine:
1. Dry wipe and predip: Begin with cleaning and preparing the udder.
2. Strip and dry: Strip teats to promote milk letdown and check for abnormalities, then dry thoroughly.
3. Attach and align: Properly attach the milking unit and align it to ensure efficiency.
Achieving the fastest milking with highest flow rates and optimal milk quality requires adherence to these steps. Proper drying enhances milk speed and reduces clinical mastitis, while complete stripping helps ensure the best let down and early detection of abnormal milk.
“Everyone will benefit by stripping. It just takes an attitude change,” Dr. Johnson notes, pointing out that the most successful herds implement this practice diligently.
He further advises that the optimal lag time between stripping and unit attachment should be at least 90 seconds. Moreover, maintaining clean cow legs—even if there’s a small amount of manure at the foot bottom—is crucial.
“Those little things really do matter,” he notes, emphasizing that attention to detail is rewarded with improved milk quality.
The Importance of Proper Equipment Management
Another critical factor in milking efficiency is the correct management of equipment, particularly the vacuum speed.
“Low vacuum is the number one problem on dairy,” Dr. Johnson states. Ensuring compatibility between vacuum speed and inflations is crucial for achieving swift, high-quality yields. “I’ve got dairies that are getting over 100 lbs. in under three and a half minutes,” he proudly asserts.
Embracing these techniques can lead to substantial improvements in both productivity and quality.
