Buy Compound Feed or Mix Your Own: How to Work Out Honestly Which Pays

What goes into the cost of your own mix besides grain and meal, why grain from your own barn isn’t free, how to compare by cost per egg and per kilogram of gain, and when mixing your own really pays.

“Compound feed is expensive, and the wheat is ours — so it’s free.” That’s how a lot of people start mixing their own feed. Six months later there are fewer eggs, a pile of premix and meal bags, the grinder has broken, and the savings have vanished. For others, their own mix really does cut the cost of an egg by a quarter. The difference is in how you count.

Your own grain isn’t free

The wheat in your barn could be sold. So its price in the mix is what the elevator or a neighbor would pay for it, not zero. This is the main mistake in the math: “free” grain makes any mix look profitable on paper.

What goes into the cost of your own mix

ItemWhat to count
GrainAt selling price, even if it’s your own
Meal, peas, fish mealAt purchase price including delivery
Premix, limestone, salt, monocalcium phosphateSmall share, noticeable cost
Grinding and mixingElectricity, wear on grinder and mixer
LaborYour hours or a worker’s pay
Losses and storageMice, mold, spills — usually 2–5%

A worked example

One tonne of layer mix. Prices in currency units per kilogram.

Say commercial feed costs 0.32 per kg. Your mix looks 19% cheaper. But that isn’t the answer yet.

Compare on cost per egg

If your mix is weaker in amino acids, hens lay less and eat more per egg.

Commercial feedOwn mix
Price per kg0.320.26
Feed per 10 eggs1.4 kg1.6 kg
Feed cost per 10 eggs0.450.42

A 19% saving per kilogram is only 7% per ten eggs. If your mix took 1.7 kg per ten eggs, the gain would almost disappear. For broilers, count the same way but per kilogram of gain (on feed conversion).

The comparison rule

Feed price per kilogram × feed per 10 eggs = feed cost per ten eggs. Compare only this number, and only on the same flock in the same season.

When mixing your own pays

When it’s better to buy

A common compromise is commercial starter for young birds and your own mix for the adult flock. How to put one together is in the article on rations from your own grain.

Run the numbers in the app

In EggPulse ingredients go into the feed store with their prices, and the recipe shows the cost per kilogram of the mix. After you switch to your own mix, analytics shows feed per 10 eggs, so the same calculation as in the table above runs on your numbers, not an example.
