Greenfeed oats + Italian ryegrass
14% dry matter, 11.5 MJ of metabolisable energy per kg of dry matter, 15% crude protein and 34% fibre (NDF) — the cited reference values behind our calculators.
Also called greenfeed cereal.
Composition
Energy is MJ ME per kg of dry matter. Everything else is a percentage of dry matter.

| Dry matter | 14% |
| Energy (ME) | 11.5 MJ/kg DM |
| Crude protein | 15% |
| Fibre (NDF) | 34% |
| Starch | 4% |

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.
