Choosing a layer strain for Pakistani conditions
Lohmann Brown dominates, but most Pakistani farm-gate egg trade is white. Which strain fits depends on your market before it depends on the bird.
A layer decision commits a shed for 72 weeks or more. That is four or five broiler cycles of consequence riding on one choice, and the usual basis for it — whichever strain the nearest hatchery is pushing — deserves better.
Start with the egg, not the bird
The first question is not which strain. It is what colour egg your market pays for.
Most Pakistani farm-gate egg trade is in white eggs. Brown-egg hybrids dominate globally and are what most published material assumes, which makes a lot of international advice quietly wrong here.
| | Brown egg | White egg | | --- | --- | --- | | Typical strain | Lohmann Brown, Hy-Line Brown | Hy-Line W-36 | | Bird size | Larger | Smaller | | Feed to maintain the hen | More | Less | | Cull value at end of cycle | Higher | Lower |
A smaller hen spends less feed staying alive and more of it making eggs. Where the market does not pay a premium for brown, that is a straightforward cost advantage.
The strains actually available
Lohmann Brown is the default commercial layer in Pakistan — 300–320 eggs to 72 weeks, first egg around 19 weeks. Feed programmes, cage systems and vaccination schedules here are largely built around it, which matters more than a marginal performance difference.
Hy-Line Brown is the main alternative, with a strong record on persistence — production falls away more slowly after peak, which matters if you run long cycles.
Hy-Line W-36 is the white-egg option, positioned on feed efficiency.
Novogen Brown publishes very high cumulative egg numbers — up to 395 to 72 weeks. Treat that as a breeder figure under ideal conditions and budget on something more conservative.
Every published egg number assumes the feed specification is actually met. Pakistani commercial rations have tested below breeder specification, and a hen fed below spec will not hit a spec number however good her genetics.
What to ask your hatchery
- Which strain, and can you supply it consistently? A strain you can only get once is not a strain you can build a programme around.
- What was the parent flock age? It affects chick weight and early performance.
- What vaccinations are already done, and on what date? This determines where your own programme starts.
- What is the expected body weight at point of lay? Uniformity at 18 weeks predicts peak production better than almost anything else.
The decision, compressed
Supplying a white-egg market and optimising feed cost per egg: a white layer such as W-36. Supplying a brown-egg market, or wanting the strain your local supply chain is built around: Lohmann Brown. Running long cycles where persistence past peak matters: Hy-Line.
In every case, availability from a hatchery you trust beats a marginal difference on paper.
