Zero milk fever across 450 cows calved

Dave Jones replaced a DCAD transition diet with X-Zelit and reported zero clinical milk fever cases across 450 cows calved — at about the same feed cost, with far fewer transition problems.

Dave explains why he moved from DCAD to X-Zelit

Hear how X-Zelit fitted into Dave’s transition program, why palatability mattered, and what changed across milk fever, mastitis, retained afterbirths and herd health.

From DCAD transition problems to zero milk fever

Dave’s key point was not that X-Zelit was cheaper feed. He described the cost as about the same as the DCAD diet it replaced — but with far fewer problems.

Before

Old transition / DCAD

  • Large clinical and subclinical milk fever incidents
  • Bad-transition problems including mastitis and retained afterbirths
  • Elevated cell count with mastitis load
  • Cows refused the DCAD ration and ate only around half
  • More assists and interventions around calving
After

X-Zelit

  • 0 clinical milk fever cases across 450 cows calved
  • 9 mastitis cases in the first 21 days, around 2%
  • Approximately 9 retained afterbirths, around 2%
  • Cell count averaging under 80
  • Very good herd health and easier calvings reported
The challenge

DCAD palatability was limiting the transition program

Dave described large clinical and subclinical milk fever incidents under the previous transition approach. The DCAD ration created a practical problem: cows did not want to eat the full ration.

In his words, the cows were only eating about half the ration, which made the transition program difficult to rely on when the herd needed it most.

The solution

A transition approach that worked in the real ration

X-Zelit replaced the DCAD diet in Dave’s program. The feed cost was described as about the same, but the practical difference was in the problems that disappeared.

Dave reported that X-Zelit worked even when cows were not eating a full ration — solving the palatability issue that had undermined the previous approach.

The result

Zero milk fever, low mastitis and strong herd health

Across 450 cows calved, Dave reported zero clinical milk fever cases. He also reported 9 mastitis cases in the first 21 days, approximately 9 retained afterbirths, and a cell count averaging under 80.

The broader result was a cleaner transition: very good herd health, easier calvings, fewer assists and the potential for better fertility through fewer retained afterbirths.

Reported outcomes

More than just milk fever

Dave’s testimonial points to a broader transition benefit: fewer fresh cow problems, easier calving and stronger milk quality indicators.

0 clinical milk fever cases
9 mastitis cases in the first 21 days
~9 retained afterbirths reported
<80 average cell count
Very good herd health described
Same cost as the DCAD diet, with fewer problems
Cost model

The value is in the problems that disappeared

Dave’s key economic point was that X-Zelit was about the same feed cost as the DCAD diet it replaced — but with far fewer transition problems. The value comes from fewer clinical cases, fewer fresh-cow issues, easier calvings and stronger milk-quality indicators.

Clinical milk fever 0 cases

Dave reported zero clinical milk fever cases across 450 cows calved.

Mastitis 9 cases

Reported in the first 21 days after calving, approximately 2% of cows.

Retained afterbirths ~9 cases

Approximately 2% of cows, supporting a cleaner transition period.

Cell count <80

Average SCC reported under 80, supporting milk quality and premium potential.

Overall result Same feed cost. Far fewer problems.

X-Zelit replaced the DCAD diet at about the same feed cost, while Dave reported zero milk fever and stronger fresh-cow outcomes.

Beyond milk fever: Dave also described easier calvings, fewer assists, better herd health, fewer retained afterbirths and a low cell count — all contributing to a stronger transition result.
In Dave’s words

What Dave said about X-Zelit

“We’ve calved 450 cows and we haven’t had one case of milk fever.”
“It’s about the same cost, but we’ve had far fewer problems.”
“The cell count is averaging under 80.”
“The herd health has been very good.”
