Rescuing Cows from Mastitis and Acidosis

The Challenge

A Herd in Crisis

In May 2022, Vosberg Valley View Farm (VVV) faced a wave of toxic mastitis that threatened to devastate their herd. Feed changes and weather fluctuations disrupted the cows’ systems, and when robotic milking equipment was introduced in June 2022, the stress compounded quickly.

The farm was soon managing sick cows every week. Milk production dropped sharply, cows were dying, and the underlying cause — subclinical acidosis — was quietly making the whole herd more vulnerable to secondary illness.

BY THE NUMBERS — BEFORE MAGNAWAVE
56% of sick cows died

Without intervention, toxic mastitis carried an overwhelming death rate. Cows that survived were often too compromised to return to the milking herd — leaving VVV absorbing the full cost of replacement.

0% of cows with toxic mastitis recovered to full production without an intervention protocol in place.

TRUSTED PEMF TECHNOLOGY

A Whole-Herd Approach

VVV needed an approach that could support recovery at scale, keep sick cows eating and ruminating, and work alongside dietary changes — without adding pharmaceutical burden to an already compromised immune system.

They turned to MagnaWave PEMF. Used alongside adjustments to reduce dietary starch and increase fiber, MagnaWave sessions were incorporated into the care protocol for every cow that showed signs of mastitis or secondary illness due to acidosis.

Supports Circulation

MagnaWave promotes increased circulation, supporting the body’s natural processes at the cellular level.

Non-Invasive

No drugs, no needles. MagnaWave is a drug-free, non-invasive PEMF modality that works with veterinary care.

Supports Recovery

Cows on MagnaWave maintained eating and rumination function during illness — a key factor in preserving body condition and resilience.

STUDY DATA – 18 HEAD OF NORMANDE CATTLE

The Numbers Tell the Story

VVV tracked outcomes across 18 head of Normande Cattle — comparing cows that received MagnaWave as part of their care protocol against those that did not.

The combined effect of reduced death loss, more cows sold with body condition, and dramatically lower replacement costs produced a measurable, sustained economic advantage for VVV.

THE RESULTS

From 56% Deaths to 89% Recovery

MagnaWave didn’t just slow the bleeding — it changed the outcome entirely. Cows that had been dying now left the farm on their own feet, with body condition, loaded onto trailers as recoveries rather than casualties. Cows that recovered went back to work in the milking herd.

VVV has since established new internal protocols combining MagnaWave with herd-specific dietary management. The results set a new benchmark for how dairy operations can approach toxic mastitis and acidosis-related illness.

UNIVERSITY RESEARCH

What the Science Shows

The results at Vosberg Valley View Farm weren’t a fluke. MagnaWave partnered with the University of New Hampshire to study PEMF’s effects on dairy cattle in a controlled research setting — measuring the indicators that matter most to producers: udder health, inflammation, and milk production.

The UNH study enrolled 35 Jersey cows in three groups — control, once-daily PEMF, and twice-daily PEMF — across a 10-day protocol: a 2-day baseline, 3 days of daily sessions, and a 5-day follow-up.

$2B
ANNUAL COST

Mastitis costs U.S. dairy farmers an estimated $2 billion every year in lost production, discarded milk, and replacement animals. For organic operations, the challenge is even greater — antibiotics aren’t an option, leaving producers with few effective tools.

ANIMALS

35 Jersey Cows

Divided into control, once-daily PEMF, and twice-daily PEMF groups with comparable baselines

WHAT WAS MEASURED

4 Key Markers

Milk yield, milk composition (fat, protein, lactose), somatic cell count, and blood inflammation markers

KEY FINDINGS

Somatic Cell Count Decreased

PEMF-treated cows showed a significant reduction in somatic cell count (SCC) compared to the control group — a direct indicator of improved udder health and reduced subclinical mastitis. The reduction persisted even after daily sessions ended.

A Specific Udder-Health Signal

The improvement showed up in the measure that matters most to producers: somatic cell count. Blood markers remained within normal ranges throughout the study, consistent with the healthy status of the enrolled cows.

Milk Production Maintained

PEMF did not reduce milk yield or change milk components — fat, protein, and lactose all held steady. The udder-health improvement came at no cost to productivity or milk quality.

Benefits Lasted Beyond Treatment

Follow-up data showed that improvements in SCC and inflammation markers largely held after active sessions stopped — suggesting a sustained positive effect on the cows' overall wellness and resilience.

MACHINES USED IN THIS STUDY

Built for the Field

Three MagnaWave machines were used throughout this case study, selected for their durability, portability, and power in livestock applications.

Semi 10

Digital · Portable · Strong
A compact digital machine with strong output in a carry-anywhere form factor. Ideal for barn rounds and routine sessions.

Julian

Analog · All-Terrain · Powerful
Built for demanding environments. The Julian’s analog power delivery and rugged construction make it a workhorse for large animal care.

Sol Pro

Analog · Durable · Effective

A reliable, self-contained analog machine built for consistent daily use in livestock and equine settings.

The MagnaWave approach has changed how we think about cow health. We're not just milking cows — we're caring for them. This case study is a testament to what's possible when you combine the right tools with a commitment to your herd.
