LOHMANN BROWN-CLASSIC: Turning performance into profit

Efficiency that pays off: why iofc makes the difference

In modern egg production, success is no longer measured by egg numbers alone. Today, profitability is driven by efficiency — and one key indicator stands out: Income Over Feed Cost (IOFC).

Based on recent cage-free Random Sample Test results from 2024–2025 XXIII Ustrasice alternative system test, the LOHMANN BROWN- CLASSIC demonstrates not only strong performance but, more importantly, outstanding economic results under real production conditions.

Strong Performance Meets Economic Efficiency

LOHMANN BROWN-CLASSIC is known for its robustness and adaptability in alternative systems and superior egg quality. The latest results confirm:

Consistent egg output across flocks

Excellent livability under practical farm conditions

Stable feed intake levels

Reliable persistency beyond peak production

Top Shell Strength and Shell colour

However, what truly sets this bird apart is how efficiently it converts feed into economic return. LOHMANN BROWN-CLASSIC exceeded a list of 7 other competitors on the last Ustrasice Test (XXIII alternative system).

When it comes to profitability, egg size and egg mass play a crucial role in the poultry business.

LOHMANN BROWN-CLASSIC’s egg weight reached the highest score, as the chart above shows. Egg weight by itself is not the determining factor. Hen housed production needs to keep up high standards as too.

A well-balanced bird combines outstanding first grade egg weight with a high and persisting production, yielding to the eggmass, the money-maker parameter.

Thanks the balaced genetics of LOHMANN BROWN-CLASSIC, hen housed production was on top of the varieties, making egg mass the highest. As well known in the egg industry since decades, LOHMANN BROWN-CLASSIC eggs set the benchmark for Shell strength and low percentage of downgraded eggs. As seen in the Table, the average Breaking strength of LB-CLASSIC Eggs are well ahead of all other brown strains in this test.

Designed for Real-World Conditions

Under cage-free conditions, where variability in management, climate, and feed quality can impact performance, LOHMANN BROWN- CLASSIC proves to be a reliable and resilient choice. Its ability to maintain:

Stable production

Good body condition

Consistent egg size

Directly contributes to a predictable and strong IOFC across different environments.

IOFC – The True Profit Indicator

While egg numbers and feed intake are important, IOFC brings both together into one decisive metric: IOFC = Egg income – Feed cost

This is the official IOFC formula: IOFC = (0.80 * EM) – (0.20 * FCR * EM) Where EM stands for Egg Mass and FCR stands for Feed conversion Ratio.

For producers, this means:
The LOHMANN BROWN-CLASSIC achieves a high IOFC through an optimal balance of performance and feed efficiency:

Strong egg mass output

Efficient feed conversion

Stable production curves

Market-preferred brown eggs

This combination ensures that every kilogram of feed delivers maximum economic return.

Why IOFC Matters More Than Ever

With increasing feed prices and market volatility, focusing on IOFC is essential:

Feed represents the largest cost in egg production

Small improvements in efficiency create significant financial gains

IOFC allows better comparison between flocks, systems, and genetics

LOHMANN BROWN-CLASSIC helps producers move from performance thinking to profit thinking. Furthermore, when it comes to profitability, the conversion of what a bird eats to what it delivers plays the crucial role.

The bottom line of any profitability analysis in layer production is the Income Over Feed Costs (IOFC).

The IOFC combines the feed conversion with the egg mass and express how much saleable product (eggs) remains after the bird “pays” for the fuel (feed) it used to create it. This is the common way to express the Feed conversion in economic figures (Euro).

IOFC = 0.80 * EM – 0.20 * FCR * EM In other words, it shows how lucrative the bird is and LOHMANN BROWN-CLASSIC stood out, again!

Conclusion: Performance that Pays Off

LOHMANN BROWN-CLASSIC is more than a reliable layer — it is a profit-oriented solution for modern egg production.
