MCP and DCP inclusion rates in layer and broiler feed — kg per tonne.
Without phytase, broiler diets typically use 8–14 kg of MCP 22% per tonne in starter falling to 4–9 kg/t in finisher, and layer diets 5–9 kg/t in production; DCP 18% is used at roughly 1.20–1.25 times those rates because it carries less phosphorus per kilogram. The rate is set by the available- or digestible-phosphorus target — around 0.45% avP in broiler starter, 0.35% in finisher and 0.32–0.38% for layers — and by the calcium already coming from limestone, since Ca:avP should sit near 2:1 in broilers and the calcium supply for layers is a separate shell-quality decision. A standard phytase dose releasing 0.10–0.15 percentage points of phosphorus removes roughly 4–7 kg of MCP per tonne, which is usually the largest single lever on this line.
- MCP 8–14 kg/t broiler starter, 4–9 kg/t finisher
- DCP ≈ 1.20–1.25× the MCP rate
- avP targets 0.45% → 0.32% by phase
- Phytase removes 4–7 kg MCP per tonne
Financing
Buy feed now, pay on terms
Feed and ingredient purchases are normally financed with six instruments: export credit guaranteed by a government agency, short-term trade finance, letters of credit at sight or deferred, supplier credit, financing against stock and receivables, and public or development-bank programs. Recurring ingredient shipments are typically financed over 30–360 days.
- Export credit (ECA-backed)1–10 years (medium/long-term)
- Commercial trade finance30–360 days (revolving line)
- Letter of credit (sight or usance)Sight, or 30–180 days deferred
- Supplier (vendor) financing60–360 days deferred payment
- Structured commodity financeTied to the inventory and sales cycle
- Public & development-bank programsVaries by program, often concessional
FeedMatch does not lend money and never guarantees approval: the decision, pricing and terms always belong to the independent financing provider.

Short answer
Without phytase, broiler diets typically use 8–14 kg of MCP 22% per tonne in starter falling to 4–9 kg/t in finisher, and layer diets 5–9 kg/t in production; DCP 18% is used at roughly 1.20–1.25 times those rates because it carries less phosphorus per kilogram. The rate is set by the available- or digestible-phosphorus target — around 0.45% avP in broiler starter, 0.35% in finisher and 0.32–0.38% for layers — and by the calcium already coming from limestone, since Ca:avP should sit near 2:1 in broilers and the calcium supply for layers is a separate shell-quality decision. A standard phytase dose releasing 0.10–0.15 percentage points of phosphorus removes roughly 4–7 kg of MCP per tonne, which is usually the largest single lever on this line.
Buy phosphorus, not product
MCP and DCP are priced per tonne of product but used per unit of available phosphorus, and the two grades differ enough that the comparison is never intuitive. Feed-grade MCP carries about 22–22.7% total phosphorus at a high relative bioavailability, while DCP carries roughly 18–18.5% at a slightly lower one. That is a 20–25% difference in delivered phosphorus per tonne of product before either price is considered, and it means a DCP offer must be materially cheaper per tonne to be the better buy. The calcium content moves in the opposite direction — DCP brings around 23–24% calcium against MCP's 15–17% — so switching between them also changes the limestone in your formula, not just the phosphate line.
Phytase is the biggest single lever on the rate
Most of the phosphorus in maize and soybean meal is bound as phytate and largely unavailable to poultry and pigs. A phytase releases part of it, and the enzyme supplier publishes a matrix value — commonly 0.10–0.15 percentage points of available phosphorus at standard dose, more at the higher 'superdosing' rates. Applying that matrix removes roughly 4–7 kg of MCP per tonne of feed. Two cautions apply in procurement: take the matrix from the specific enzyme and dose you actually buy rather than a generic figure, and remember that the matrix is only real if the enzyme survives conditioning — a heat-sensitive product pelleted at 85 °C without post-pellet application may not deliver what the formulation assumed.
Calcium is a separate decision for layers
In broilers, calcium and available phosphorus are formulated together at roughly a 2:1 ratio because excess calcium binds phosphorus and depresses its availability. In layers that logic breaks down: a hen in production needs about 4.0–4.5% dietary calcium for shell formation, supplied mostly as limestone and coarse particles fed to match the overnight shell-deposition cycle, while available phosphorus stays at a comparatively modest 0.32–0.38% and falls through the laying cycle. Treating the layer phosphate inclusion as a fraction of the calcium requirement is a common and expensive error — the two are bought and dosed for different biological jobs.
MCP 22% and DCP 18% inclusion by species and phase (no phytase applied)
| Phase | Inclusion rate | Nutrient target | Note |
|---|---|---|---|
| Broiler starter (0–10 d) | MCP 8–14 kg/t · DCP 10–17 kg/t | avP ≈ 0.45%; Ca ≈ 0.90% | Highest skeletal demand of the cycle. Under-supply here shows as leg problems that later phases cannot correct. |
| Broiler grower (11–24 d) | MCP 6–11 kg/t · DCP 7.5–14 kg/t | avP ≈ 0.42%; Ca ≈ 0.84% | Hold Ca:avP near 2:1 — excess limestone here reduces phosphorus availability. |
| Broiler finisher (25 d+) | MCP 4–9 kg/t · DCP 5–11 kg/t | avP ≈ 0.35%; Ca ≈ 0.76% | The largest tonnage phase, so the phytase decision pays back most here. |
| Pullet rearing | MCP 5–10 kg/t · DCP 6–12 kg/t | avP ≈ 0.40% falling to 0.35% | Pre-lay diets step calcium up sharply while phosphorus stays flat. |
| Layer, peak production | MCP 5–9 kg/t · DCP 6–11 kg/t | avP ≈ 0.38%; Ca 4.0–4.3% | Calcium comes from limestone, not from the phosphate. Include a coarse limestone fraction for overnight shell deposition. |
| Layer, late lay (65 wk+) | MCP 3.5–7 kg/t · DCP 4–8.5 kg/t | avP ≈ 0.32%; Ca 4.2–4.5% | Phosphorus falls while calcium rises — the classic late-cycle adjustment for shell quality. |
Product, regulatory and handling limits
| Item | Detail |
|---|---|
| MCP feed grade | ≈ 22.0–22.7% total P, ≈ 15–17% Ca; high relative bioavailability |
| DCP feed grade | ≈ 18.0–18.5% total P, ≈ 23–24% Ca; slightly lower relative bioavailability |
| Substitution | Replace 1 kg of MCP with about 1.20–1.25 kg of DCP on phosphorus, then rebalance limestone for the extra calcium |
| Contaminant limits | Fluorine and heavy metals are the binding constraints — verify against the destination market limit on every CoA, since phosphate rock origin varies |
What a phytase matrix is worth per tonne
| Basis | Value |
|---|---|
| MCP displaced by a 0.12 pp phytase matrix | ≈ 5.5 kg per tonne of feed |
| At USD 480/t MCP delivered | USD 2.64 saved per tonne of feed |
| At USD 650/t MCP delivered | USD 3.58 saved per tonne of feed |
| Less typical phytase cost | USD 0.60–1.40 per tonne of feed at standard dose |
| Net effect, 20,000 t/yr mill | USD 25,000–60,000 per year, before the limestone rebalance |
Reproduce this with your own prices. A phytase matrix that releases 0.12 percentage points of available phosphorus removes about 5.5 kg of MCP 22% per tonne of feed.
