Livestock Unit Calculator

Convert livestock numbers to total Livestock Units (LU), LU per hectare and LU per acre, using the DEFRA Countryside Stewardship Annex 6C conversion table.

On a moorland grazing action? SFI26 and Countryside Stewardship Higher Tier set those limits as a maximum GLU per hectare — 0.04, 0.08 or 0.16 depending on the action. Enter your numbers below and the results compare your figure against each published limit. Grassland actions managed by sward height instead are covered by our Grassland Grazing Checker.

Enter livestock numbers

The seven categories in DEFRA Annex 6C, plus the two the 2026 scheme guidance adds. Leave blank or enter 0 if not applicable.

Pig and poultry are not in Annex 6C. Their values come from the CSHT action guidance, where a Natural England adviser decides the figure for the livestock in question and may use 0.44 and 0.017 — leave them at 0 unless your agreement says otherwise.

Lambs at foot have no separate allocation: DEFRA counts them inside “ewe and lamb”, so count the ewe once and leave the lamb out.

Livestock unit conversion table (DEFRA Annex 6C)

Livestock categoryLivestock Units eachAnimals per 1 LU
Cattle over 2 years1.001
Cattle 6 months to 2 years0.60~1.7
Horse1.001
Pony or donkey0.801.25
Lowland ewe, lamb or ram0.12~8.3
Store lamb, hill ewe, hogg or teg0.0812.5
Goat0.12~8.3

So 1 Livestock Unit ≈ 1 adult cow ≈ 1 horse ≈ 8–9 lowland ewes ≈ 12–13 hill ewes. "Animals per 1 LU" is simply 1 divided by the DEFRA coefficient.

Two more categories in the 2026 scheme guidance

Livestock categoryGLU eachAnimals per 1 GLU
Pig0.44~2.3
Poultry0.017~59

These two are absent from Annex 6C and appear in the Countryside Stewardship Higher Tier action guidance (CSP16, updated 28 April 2026), which introduces the list with the words that a Natural England adviser “will decide on the appropriate value depending on the type and breed of livestock” and may use these figures. Treat them as the adviser’s starting point, not a fixed rate.

How many cattle or sheep per acre?

The calculator gives livestock units per acre; turning that back into animals is one division, because a unit is defined as one adult bovine. Divide your LU/acre by the coefficient for the animal you are asking about:

  • Cattle over 2 years (1.00): 0.5 LU/acre is 0.5 head per acre — one beast per two acres.
  • Cattle 6 months to 2 years (0.60): 0.5 ÷ 0.60 = 0.83 head per acre.
  • Lowland ewes (0.12): 0.5 ÷ 0.12 = 4.2 ewes per acre.
  • Hill ewes, hoggs, tegs, store lambs (0.08): 0.5 ÷ 0.08 = 6.3 per acre.

One hectare is 2.4710538 acres, which is the conversion the calculator uses. Nothing here says how many animals an acre should carry — DEFRA publishes no lowland figure, and the nearest published guide is AHDB’s range below.

How many sheep or cattle per hectare? AHDB’s guide stocking rates

DEFRA sets no lowland figure, but AHDB does give a range, in its grazing manual Planning grazing strategies for better returns (2018, page 14):

Low stocking rateHigh stocking rate
AHDB LU per hectare1–1.52–2.5
AHDB LU per acre0.4–0.60.8–1
Lowland ewes per hectare9–1418–23
Lowland ewes per acre3.7–5.57.4–9.2
Beef cows per hectare1.3–22.7–3.3
Beef cows per acre0.5–0.81.1–1.3
Other cattle over 2 years per hectare1.3–1.92.5–3.1
Other cattle over 2 years per acre0.5–0.81–1.3
Cattle 12–24 months per hectare1.5–2.33.1–3.8
Cattle 12–24 months per acre0.6–0.91.2–1.6

AHDB’s note on the two ends: a high stocking rate uses more of the grass and makes pasture quality easier to hold; a low one makes higher gain per head easier, as long as the pasture is good. It also says the rate moves with land grade, nutrient use, any stewardship agreement and grazing quality.

These are not the livestock units the calculator uses. AHDB counts one LU as the feed energy a mature dairy cow needs for maintenance (from Defra’s 2010 farm business management definitions), so a lowland ewe is 0.11, a beef cow 0.75 and other cattle over two years 0.80. Annex 6C, which the calculator follows, makes every bovine over two years 1.0 and a lowland ewe 0.12. For the same herd of beef cows the Annex 6C figure comes out a third higher than AHDB’s, and for lowland ewes about 9% higher — so to read your stock against this table, count it again in AHDB’s units below. The animal rows are our arithmetic, not AHDB’s print: the per-hectare range divided by AHDB’s figure for that animal (0.11 lowland ewe, 0.75 beef cow, 0.80 other cattle over two years, 0.65 other cattle 12–24 months), then by 2.4710538 for acres. AHDB defines one LU as a mature dairy cow’s maintenance energy, so the first two rows also read as dairy cows per hectare and per acre.

Count your stock in AHDB’s units

For scheme limits and records, the Annex 6C figure at the top of this page is the one that counts. This second count only lets you read your stock against AHDB’s range, using AHDB’s own categories from Table 6 of the manual. Horses, ponies, goats, pigs and poultry are not in that table, so they are left out here, and the table gives no separate figure for lambs at foot.

How many animals can your grass feed?

The ranges above come from experience across many farms. The same AHDB manual also works it out from the grass itself: how much grows in a typical month in England under moderate nitrogen use (Table 1), how much of it a grazing system actually gets eaten (Table 2), and how much each animal eats a day as a share of its liveweight (Table 8). Put in one class of stock and the calculator does that arithmetic.

Frequently asked questions

What is a livestock unit (LU)?

A livestock unit is a standard way of expressing different types and ages of grazing animals on a common scale, so that stocking can be compared across species. In the DEFRA Countryside Stewardship system, one LU corresponds to one adult bovine over two years old, and every other category is a fraction of that (see the table above).

How many sheep count as one livestock unit?

Using the DEFRA Annex 6C coefficients: a lowland ewe, lamb or ram counts as 0.12 LU, so roughly 8–9 of them make one LU. A store lamb, hill ewe, hogg or teg counts as 0.08 LU — exactly 12.5 per LU.

How do I calculate livestock units per hectare?

Convert each group of animals to livestock units using the coefficients above, add them up, then divide the total by your grazing area in hectares. Example: 20 adult cattle (20 LU) plus 100 lowland ewes (100 × 0.12 = 12 LU) on 25 ha gives 32 LU ÷ 25 ha = 1.28 LU/ha. That is exactly what the calculator above does — including the per-acre figure.

What stocking rate is "right" for my land?

This calculator deliberately does not tell you, and neither does DEFRA: Annex 6C publishes the conversion table with no accompanying benchmark, and the only LU/ha figures in DEFRA’s guidance are the moorland action limits (0.04, 0.08 and 0.16 GLU/ha). AHDB’s grazing manual offers a guide — 1–1.5 LU/ha at the low end, 2–2.5 at the high end, in AHDB’s own units (see above) — and says the rate moves with land grade, nutrient use, stewardship agreements and grazing quality. Off moorland, the appropriate rate depends on habitat, soil, rainfall, sward quality and your farm system. Use the number as a comparison point and talk to your agronomist or feed advisor.

Does this check my SFI or Countryside Stewardship limits?

It compares, it does not certify. Moorland grazing actions are written as a maximum GLU per hectare — 0.08 for UPL2 and CUP9, 0.04 for UPL3 and CUP10, 0.16 for CUP8 — so the results above put your figure next to each of them. Other grassland actions are managed by sward height and seasonal rules instead; for those, use our Grassland Grazing Checker. Either way the agreement, the mapped area and the stocking calendar decide compliance, not this page.

Is a GLU the same as a livestock unit?

For these purposes, yes. The 2026 action guidance says grazing livestock units (GLU) and lists the same coefficients as Annex 6C — a cow over two years is 1.0 in both. The 2026 list adds pig (0.44) and poultry (0.017), which Annex 6C does not contain, and notes that a Natural England adviser decides the value that actually applies to your livestock.

Do lambs at foot count separately?

No. DEFRA’s moorland action guidance states that lambs at foot have no separate GLU allocation and are included in the figure shown for “ewe and lamb”. Count the ewe once; do not add her lamb as a second animal.

What about manure nitrogen limits (NVZ)?

The 170 kg N/ha/year livestock manure limit in Nitrate Vulnerable Zones is a separate calculation based on nitrogen produced, not livestock units. If your land is in an NVZ, start with our NVZ checker.

About this calculator

Livestock Unit coefficients are taken verbatim from DEFRA Countryside Stewardship Annex 6C. Contains public sector information licensed under the Open Government Licence v3.0. Crown copyright 2023.

What this tool does: converts livestock numbers to total Livestock Units (LU) and LU per hectare using Annex 6C, the table the schemes use. A separate, optional count does the same in AHDB’s grazing-manual units, only to read your stock against AHDB’s guide range. A third part estimates how many animals of one class a season’s grass growth can feed, using AHDB’s grass-budget tables.

What this tool does not do: recommend whether your stocking rate is appropriate. Suitable LU per hectare depends on habitat, soil, rainfall, sward quality, farm system, and — where applicable — the specific stocking rules of your Countryside Stewardship or Sustainable Farming Incentive agreement.

For decisions about your farm, consult a feed advisor, agronomist or veterinary surgeon. For Countryside Stewardship compliance, check your agreement documents or contact the Rural Payments Agency.

Pig (0.44) and poultry (0.017) come from the Countryside Stewardship Higher Tier action guidance, not from Annex 6C — see CSP16, updated 28 April 2026, where the values are the ones a Natural England adviser may apply. Deer and cattle under 6 months appear in neither list; for those, refer to your agreement schedule.

Scheme limits and payment rates on this page were read from the GOV.UK action pages for UPL2, UPL3, CUP8, CUP9 and CUP10 on 7 September 2026.
