Annual Fodder & Need & Land to Grow It
Feeds cattle
To keep a herd fed year-round you must grow or buy enough green fodder. Enter herd size, daily fodder and yield to get your annual need and the land area — and avoid dry-season shortages.
Plan your fodder land
Next: set aside about 1.4 ha for multi-cut green fodder (e.g. hybrid napier or lucerne) and stagger sowing so cuts land year-round.
Assumes a steady year-round daily intake and the given annual fodder yield; real area varies with crop, irrigation, cutting interval and a buffer for lean months.
Annual fodder — key facts
- Daily total
- animals × daily fodder
- Annual need
- daily total × 365
- Fodder area
- annual tonnage ÷ yield/ha
- Cow intake
- ≈ 25–40 kg green/day
- Multi-cut yield
- 80–250 t/ha/yr irrigated
- Safety margin
- plan 10–20% extra
- Buffer
- conserve hay or silage

Grow enough green, every day of the year
Animals eat every single day, but fodder crops grow in flushes and stall in the dry season. The way to bridge that gap is to plan the whole year at once: how many tonnes of green fodder the herd will eat over 365 days, and how much land you must keep under fodder to grow it. Get the land area right and the herd stays fed through the lean months; get it wrong and you are buying expensive feed when supply is tightest.
This tool gives the daily fodder total, the annual tonnage and the land area from your herd size, daily fodder per head and expected fodder yield per hectare. Use it to size your fodder plots, schedule successive crops, and decide how much surplus to conserve as hay or silage. Pair it with the Pasture Budget, Silage Pit Capacity and Livestock Feed tools for a full feeding plan.

Frequently Asked Questions
What is an annual fodder requirement?+
It is the total green fodder a herd will eat across a whole year. To keep animals fed year-round you must grow or buy enough fodder for every day — the annual figure tells you how many tonnes you need and, crucially, how much land you must keep under fodder crops to grow it.
How is the annual fodder requirement calculated?+
Daily total = number of animals × daily fodder per animal. Annual need = daily total × 365. The land needed = annual tonnage ÷ fodder yield per hectare. For example 10 cattle eating 30 kg green fodder each is 300 kg/day, about 110 tonnes a year, needing roughly 1.4 ha at 80 t/ha yield.
How much green fodder does one animal eat per day?+
A typical adult cow or buffalo eats around 25–40 kg of green fodder daily depending on body weight, milk yield and the dry-feed ration alongside it. Smaller stock eat less. Use your own figure per head — the calculator multiplies it by the herd size and the days in the year.
Why plan a whole year of fodder at once?+
Pasture and fodder crops grow seasonally, but animals eat every day. Planning the full year exposes the gap between peak growth and the lean dry season, so you can set aside enough land, schedule successive fodder crops, and store surplus as hay or silage rather than being caught short when growth stops.
What fodder yield should I use per hectare?+
It depends on the crop and conditions — multi-cut green fodders like hybrid napier or maize can give 80–250 t/ha of green matter a year under irrigation, while rain-fed fodders give far less. Use a realistic local figure; a lower yield simply means you need more land to meet the same tonnage.
How does this help avoid dry-season shortages?+
By sizing the land and tonnage for the entire year, you see early whether your current fodder area can carry the herd through the months when nothing grows. If it can't, you can expand the fodder area, conserve surplus from the flush as silage or hay, or adjust herd numbers before the shortage bites.
Does it work for any livestock or land unit?+
Yes — it works for cattle, buffalo, sheep or goats; just enter the right daily fodder per head and the number of animals. Enter your fodder yield per hectare and the tool reports the land area you need, which you can read across to acres or local units.
Should I add a safety margin?+
It is wise to. Real fodder supply varies with weather, pests and crop establishment, and animals waste some fodder. Many farmers plan 10–20% more land or tonnage than the bare calculation, and treat conserved hay or silage as a buffer for poor seasons.
Are the figures precise?+
They are solid planning figures. Actual consumption shifts with milk yield, body condition and the rest of the ration, and field yields vary year to year. Re-check your daily intake per head and local fodder yields, and revise the plan each season — fodder budgeting is about steering, not exact prediction.
