It began with the idea…

In the fall of 1999, like so many autumn seasons, calf morbidity and mortality were spiking as the weather turned for the worse in Colorado. In discussion with a progressive dairy client, Dr Richard Dumm wanted to explore the notion of pasteurizing the waste milk being fed to his calves — improving the "groceries" while decreasing the "bug" load in the food source. Nothing was available at the time other than $25,000–$50,000 machines. For this 600-cow dairy, the high price was not an option. Using a bit of innovative shop work and a quick study of electronic control systems, the first prototype was constructed and placed in the parlor. The equipment had an eerie resemblance to a moonshine still; nonetheless, the results were almost immediate.

• Calf scours dropped 90%
• Weight gains were noticeable within days
• Mortality rate plummeted (from a rate topping 12%)
• Employees rejoiced!

By early 2000, Dairy Tech LLC was officially registered as a Colorado corporation. Engineers were hired to transform the moonshine-still prototype into something that looked, and behaved, like real equipment. Progress was slow and expensive — but not nearly as slow as the education piece. Rick spent the next four years explaining the idea to colleagues and dairy producers, most of whom had been told for decades that pasteurization wasn't worth the trouble.

First academic validation: a University of Minnesota field trial in 2003. A handful of farms, willing to try the equipment in real conditions. The results were compelling enough to open minds that had been closed for years. So Dairy Tech hit the trade-show circuit and started spreading the word the only way that actually works — one operation at a time.

2006 saw the first colostrum pasteurization trials on a 2,500-cow dairy in Colorado. Prior to that, it was deemed that colostrum could not be pasteurized. With the aid of Dr Sandra Godden at the University of Minnesota, the trials proved that the colostrum was difficult to work with — but that the absorbed levels in the blood of the calf far outweighed those fed raw colostrum. Further studies determined the exact temperatures and times that would yield both a quality product and one protected from degradation. Dairy Tech had become the ONLY company in the world with proven results in the pasteurization of colostrum for cattle.

Even after pasteurization, customers found new ways to contaminate the colostrum between the machine and the calf. A new bucket here. A poorly cleaned bottle there. The system was as weak as its weakest link. The answer was a scientifically designed, single-use aluminum bag. Store, refrigerate, freeze, reheat, feed — all from one sealed bag, then discard. No re-contamination surface. No cross-batch transfer.

• 3,000,000+ bags sold in 2020 alone
• 95% customer retention rate

Even with the bag, dairies were still ruining the colostrum in the last 60 seconds — buckets of hot tap water, guesswork on temperature, proteins damaged or under-absorbed. Too cold and IgG absorption drops; too hot and the proteins denature. MilkWorks™ solved the thaw-and-warm step with a pre-warmed water bath designed around the bag itself (and works with standard 2-quart bottles too). The last 60 seconds finally became as controlled as the first 60.

Oxford Ag launched as a sister line — products you fill with warm water, shake, and feed. No reconstitution math, no calibration, no extra steps for the calf-care employee at 4 AM.

All packaged in the Perfect Udder®.

Research kept showing the same pattern — a second feeding of 2L within 8 to 12 hours of birth materially improved health outcomes and lifetime production. The first feeding gets headlines. The second feeding gets results. Dairy Tech released the 2L Perfect Udder® bag specifically for that critical second feeding.

Small calves need a tube with a smaller safety bulb — gentler on the esophagus, but still wide enough to resist insertion into the trachea. Nobody made one. Dairy Tech's R&D produced an esophageal tube specifically for calves under 66 lbs / 30 kg. Disposable. Biosecure. Still the only one of its kind in the world. The same year, the original Perfect Udder® bag got its patented Center-Seal redesign: 30%+ better heat transfer, faster cooling and heating, easier stacking and storage.

The larger pasteurizers did high volumes well. But the workflow had evolved — most dairies were running individual Perfect Udder® bags, and a pasteurizer designed around the bag itself was overdue. Matilda® was an immediate hit, domestically and internationally. The Perfect Udder® App launched the same year, giving customers a way to interact with her remotely.

Adda™ is the high-volume answer to Matilda's mid-volume win. Stainless-steel enclosure. Swing-away touchscreen controller. Full integration with the Perfect Udder® App. Same mission, scaled up: kill pathogens, simplify the workflow, improve biosecurity, lower costs, raise profits. Today, the scientific community has publicly named Dairy Tech the gold standard in wet-calf management — with units on 20+ university research sites across the US.
