Chloride is left out on purpose: standard lab digestion doesn't recover it, so published feed tables leave it blank and ours would be an estimate. A mineral left out here is one the source table didn't report — not a measured zero.

Where these numbers come from

A 50:50 mix of DairyNZ Facts & Figures Ch.5 “Oats (grazed crop)” and Pacheco et al. (2023) on New Zealand winter-grown Italian ryegrass (PubMed Central PMC10603665).

Grazing stage moves the energy a long way — a young leafy crop will do better than shown.

A dash under c/MJ means the feed isn't bought — grazed pasture and standing crops carry no purchase price, and showing them at zero would read as free.

Does it feed the animal?

A composition on its own can't tell you that. Open the calculator with Greenfeed oats + Italian ryegrass added to the diet, set your stock and how much of it they're getting, and it will tell you what the diet actually supports — and which of energy, protein or gut fill runs out first.

Feedwise gives indicative models for decision support. It is not a substitute for a nutritionist or veterinarian — for animal-health decisions, talk to your vet.
