Lucerne (fresh)
20% dry matter, 9.4 MJ of metabolisable energy per kg of dry matter, 20.6% crude protein and 39% fibre (NDF) — the cited reference values behind our calculators.
Also called alfalfa.
Composition
Energy is MJ ME per kg of dry matter. Everything else is a percentage of dry matter.
| Measure | Value |
|---|---|
| Dry matter | 20% |
| Energy (ME) | 9.4 MJ/kg DM |
| Crude protein | 20.6% |
| Fibre (NDF) | 39% |
| Starch | 0.3% |
| Sugar | 5.6% |
| Fat | 2.9% |
Macro-minerals, % of dry matter

- Magnesium
- 0.25%
- Sodium

- Potassium
- 2.84%
- Sulphur

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
Feedipedia, fresh lucerne (alfalfa) at the vegetative stage (ref. 275).
How it compares
Other forages in the library, ordered by how close they sit to Lucerne (fresh) on energy.
| Feed | DM % | ME | Protein | Fibre | c/MJ |
|---|---|---|---|---|---|
| Lucerne (fresh)this page | 20 | 9.4 | 20.6% | 39% | — |
| Pasture — summer (stemmy) | 25 | 9.5 | 12.5% | 57% | — |
| Pasture hay | 85 | 9 | 10% | 60% | 4.6c |
| Baleage (pasture) | 45 | 10 | 14% | 52% | 2.9c |
| Whole-crop cereal silage | 35 | 8.7 | 10% | 48% | 3.3c |
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 Lucerne (fresh) 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.
