Pasture / feed analysis

Import a lab report to base the mineral and trace-element risks on your own pasture. It’s shared with Feed analysis too.

Example pasture. Import a Hill Labs or Eurofins report (here or in Feed analysis) to see risks for your own pasture.
Facial eczema — preventive zinc
Zinc oxide
12.0g/head/day
Elemental zinc
9.6g/head/day

At 20 mg zinc/kg liveweight/day for a 480 kg beast. Start 2–3 weeks before spore counts rise and continue through the danger period.

Match any product's stated elemental zinc to this daily target — boluses especially vary in payload and release rate.

Prolonged zinc dosing can lower copper status — worth a copper check during an extended facial-eczema programme, especially on high-molybdenum country where copper is already tight.

Zinc is toxic in excess (and poisoning looks like facial eczema). Don’t exceed this preventive rate or dose longer than ~100 days without veterinary advice.
Metabolic & mineral risk
Grass staggers1.4 Ca / P2.1 DCAD269 !K / Na12 Sulfur0.33

DCAD elevated — worth watching for springers near calving. Milk fever (DCAD) matters most for springers; grass staggers for lactating stock.

Trace elements

No trace elements on this analysis. Import a Eurofins report (which includes copper, cobalt, selenium and more) to assess trace-element status here.

Herbage ↔ animal status

Have a liver copper, blood selenium or B12 test? Add the mob result to compare it against this pasture — and catch a copper “lock-up” the pasture alone can’t show.

Indicative risk model for decision support — thresholds follow recognised animal-health and trace-element guidance. Not a substitute for a vet.

Spotting metabolic and mineral risk

See the metabolic and mineral risks your stock are carrying, worked out from your pasture or feed analysis. Feedwise flags the big ones — milk fever and grass-staggers risk by stock class, and trace-element shortfalls — and includes a facial-eczema zinc-dose calculator so you can get the rate right per head.

Common questions

How do you work out the facial-eczema zinc dose?

From the animal's liveweight and the standard preventive zinc rate, giving you a per-head daily amount. It is for prevention planning — confirm dosing and timing with your vet.

What is grass staggers, and how is the risk estimated?

Grass staggers (low blood magnesium) is estimated from the mineral balance of your feed — particularly the potassium, calcium and magnesium relationship that drives magnesium uptake.

What is milk-fever risk based on?

The calcium status and dietary cation–anion balance of the diet around calving or lambing, when demand spikes.

Which trace elements does it cover?

The common ones drawn from your pasture analysis — including selenium, copper, cobalt and zinc.

Is this veterinary advice?

No — it is indicative and is not a substitute for your vet.
