🔥 Metabolic chaos doesn’t start at calving. Calving just exposes it.
That’s the bit most farms miss.
Because from the outside, the dry period can look like the quiet part of the season.
The cups are off.
Cows are taking a break.
Everything looks like it has slowed down.
But inside the cow?
It’s not quiet at all.
There’s a biological storm building.
She’s carrying a calf.
Her intake is under pressure.
Her mineral demand is climbing.
Her immune system is under load.
Her rumen is adjusting to feed changes.
Her body is preparing to go from dry cow to milking cow almost overnight.
Then throw in winter crop imbalances, cold snaps, tight feed, lower intakes, walking, crap weather…
And those stresses starts to compound.
So when calving hits, it doesn’t create the chaos.
It reveals it.
That’s when farmers start seeing the signs.
A few too many wobbly ones.
More time spent treating problems.
Cows not milking like they should.
Here’s a mind blowing fact from DairyNZ.
For every obvious clinical down cow, there are 7 subclinical cows.
Still walking.
Still eating.
Still in the herd.
But not firing.
That’s where the cost hides.
The average NZ dairy farm can lose around $75,000 a season through metabolic-related chaos.*
Not in one big invoice.
In lost milk.
Extra treatments.
More hassles at calving.
Cows slower to recover.
And too often, it gets written off as:
“Just one of those seasons.”
But it doesn’t have to be.
