Pre-layer feed should be used for a short pe-
riod of time before a flock starts being sup-
plied with phase 1 layer feed. This leads to
a smooth transition from the developer feed
(low calcium and low nutrient density) to a
diet with high calcium and nutrient levels.
It helps to avoid the often reduced appe-
tite/daily feed intake during early produc-
tion. Typically, pre-layer feed contains about
2.0–2.5% calcium. This is too much for a
typical feed for rearing but not enough for a
bird starting to produce eggs. From a nutri-
tional point of view, it’s therefore considered
a compromise and never as “optimal” feed.
Nevertheless, it’s worthwhile to use pre-layer
feed for a short period of time. Correct use
can enhance the uniformity of a pullet flock.
It’s especially beneficial for flocks with very
low uniformity and also aids the develop-
ment of Ca-metabolism in medullar bones.
Since pre-layer feed is a compromise feed for
the short transition period, it cannot supply a
bird in full lay sufficiently. Therefore, it cannot
be used when feed logistics and correct tim-
ing do not work.
Please consider the following recommenda-
tions while using pre-layer feed:
Start using pre-layer feed dependent on
to the birds sexual maturity, age and their
standard body weights.
Use pre-layer feed for about 10 days with a
maximum of 1 kg per bird.
The wrong way to use pre-layer feed is ei-
ther to start using it too early and/or use it
For example if the onset of lay is scheduled
for the 19
weeks of age, you may start feed-
ing the birds with pre-layer feed only after
they are 17 weeks old.
In case of an earlier or later production, ad-
just this schedule accordingly.
