Not a hint of milk fever across two calvings

Asher and Lydia Whiting introduced X-Zelit into their transition program in Forest, Tasmania and reported no milk fever, no flow packs and no cow losses — even in older, high-risk cows.

Asher and Lydia explain the difference X-Zelit made at calving

Hear how X-Zelit fitted into their feeding routine, helped remove the stress of flow packs and supported older cows through a high-risk calving profile.

From milk fever pressure to calm, confident calving

This was a tough test: older cows, extended lactations and multiple calvings each year. Asher and Lydia described X-Zelit as easy to use and reported a dramatic change in milk fever, flow packs and cow losses.

Before X-Zelit

A lot of milk fever pressure

  • Generally a lot of milk fever
  • Flow packs used regularly
  • Cows down around calving
  • Older cows were considered a “sure thing” for milk fever
  • Milk fever deaths were a real risk
  • Higher mastitis pressure after calving
After X-Zelit

No hint of milk fever

  • No milk fever reported across the last two calvings
  • No flow packs used
  • No dead cows reported
  • Cows over 12 years old calved without milk fever
  • Definitely a reduction in mastitis
  • Cows milking better for longer
The challenge

Older cows, long lactations and repeated calving risk

Asher and Lydia described their previous calving experience as having generally a lot of milk fever, with flow packs used all the time and cows going down.

Their system also created a high-risk profile: older cows, including cows over 12 years old, extended lactations around 360 days and calving three times a year.

The solution

Easy feeding over the first two feeds

X-Zelit fitted into the existing routine. Asher and Lydia described it as actually quite easy: the usual ration, with half a kilo of X-Zelit on top for the first two feeds.

That simple change gave them a practical way to support cows through the calving window without adding unnecessary complexity.

The result

No milk fever, no flow packs and no dead cows

Across the last two calvings, Asher and Lydia reported not even a hint of milk fever. They also said they had not used a flow pack and had not had a dead cow.

The result was not limited to milk fever. They also described a definite reduction in mastitis and cows milking better for longer.

Reported outcomes

Strong results in a high-risk cow profile

The standout is that the result held even in older cows that would previously have been expected to get milk fever.

0 milk fever signs reported
0 flow packs used
0 dead cows reported
12+ yrs older cows calved without milk fever
Reduced mastitis after calving
Longer cows milking better for longer
Farm value

The value is in fewer emergencies and better cows after calving

For Asher and Lydia, the value was not just in reducing milk fever. It was in removing the day-to-day calving pressure: no flow packs, no down cows, no dead cows, fewer mastitis issues and more confidence through repeated calvings.

Milk fever None

Not even a hint of milk fever reported across the last two calvings.

Flow packs None

No flow packs used since introducing X-Zelit.

Cow losses None

No dead cows reported from milk fever pressure.

Mastitis Reduced

A definite reduction in mastitis was reported after calving.

Overall result Calmer calving. Better cows. More confidence.

X-Zelit helped take the pressure out of milk fever management, even in older, high-risk cows.

Beyond milk fever: Asher and Lydia also described peace of mind at calving, fewer emergency interventions and cows milking better for longer.
