Broiler Feed Calculator: Phase Split, Tonnage and Cost per Bird
Size a broiler cycle in tonnes and split it across starter, grower and finisher so each phase can be ordered on its own specification and delivery date.

A broiler cycle needs about live weight produced × FCR in feed, split roughly 12% starter, 33% grower and 55% finisher. For 25,000 birds grown to 2.5 kg at FCR 1.62, that is about 98 tonnes: 12 t starter, 32 t grower and 54 t finisher, or 3.9 kg of feed per bird placed.
The formula
- Feed per cycle = surviving birds × target weight × FCR + mortality allowance
- Phase tonnage = feed per cycle × phase share (12 / 33 / 55%)
- Annual requirement = feed per cycle × cycles per year
Worked example — 25,000 broilers, 6 cycles a year
- · 25,000 birds
- · 2.5 kg target
- · FCR 1.62
- · 4% mortality
- · 430 per tonne
- → ≈ 98.3 t per cycle: 11.8 t starter, 32.4 t grower, 54.1 t finisher
- → 3.93 kg of feed and about 1.69 in feed cost per bird placed
- → ≈ 590 t a year — enough volume to tender rather than buy spot
Broiler FCR by target weight
| Category | Typical range | What it means |
|---|---|---|
| 1.8 kg | FCR 1.45–1.55 | Fast cycle, high starter share. |
| 2.2 kg | FCR 1.55–1.65 | Most common commercial target. |
| 2.5 kg | FCR 1.58–1.70 | Balanced cost per kg carcass. |
| 3.0 kg+ | FCR 1.70–1.85 | Heavier birds convert less efficiently. |

Turn the tonnage into offers
Once you know the tonnage, the next step is pricing it. Send the volume and the specification and we run it across qualified manufacturers and ingredient suppliers, then return every offer normalised to landed cost per tonne. Supplier-neutral and free for buyers.
