How to Formulate a Livestock Meal Mix & Calculate True Costs
Home-mixing can cut feed costs by £30–£80 per tonne compared to buying compound feed — but only if the ration is nutritionally balanced and you know your real cost per tonne.

Open Meal Mix CalculatorThe Three Pillars of Ration Formulation
Energy (ME)
Measured in MJ/kg DM. Drives milk production and liveweight gain. Target 11.5–12.5 for high-yielding dairy cows.
Protein (CP)
Essential for milk solids and growth. 16–18% for dairy, 14–16% for finishing cattle.
Fibre (NDF)
Maintains rumen health. Minimum 28–35% depending on production stage to prevent acidosis.
How to Calculate True Cost per Tonne
Don’t forget “hidden” costs: milling electricity, labour, mineral/vitamin premix (usually 1–2%), and transport. Our calculator automatically handles weighted averages.
2026 Typical UK Feed Values
| Ingredient | ME (MJ/kg DM) | CP (%) | NDF (%) | Approx. Cost/t (2026) |
|---|---|---|---|---|
| Rolled Barley | 13.0–13.4 | 11–12 | 18–22 | £220–£260 |
| Soya Bean Meal (Hi-Pro) | 13.3 | 47–49 | 12–15 | £380–£450 |
| Rapeseed Meal | 12.5 | 36–38 | 25–30 | £260–£310 |
| Sugar Beet Pulp | 12.3 | 9–11 | 38–42 | £180–£230 |
Practical Formulation Tips
The 1–2% Rule
Always include 1–2% high-quality mineral/vitamin premix. Deficiencies here can cancel out the benefits of a good energy/protein balance.
Introduce Changes Gradually
Sudden ration changes can cause digestive upsets. Transition over 7–14 days.
Moisture Matters
Test home-grown grain for moisture. Wet grain dramatically reduces energy density.
NDF is Non-Negotiable
Keep effective NDF above 28–32% in most rations to maintain rumen health.

Frequently Asked Questions
How much can I save by home mixing?
Most farms save £30–£80 per tonne compared to buying compound feed, depending on scale and ingredient prices.
What is a good target cost per tonne?
In 2026, a well-balanced dairy TMR typically lands between £220–£280 per tonne depending on performance level and raw material costs.
Should I get my own feed analysed?
Yes — especially home-grown cereals and forages. Lab analysis every 4–6 weeks during the feeding season is recommended.
