has been reached. A reduced nutrient density

and an increased content of crude fibre (5–

6 %) during this phase is beneficial for

improving eating capacity. The pre-layer diet

has about twice the calcium content of

developer as well as higher levels of protein

and amino acids. Feeding such a diet for

about 10 days prior to the planned start of lay

is therefore beneficial. This diet improves

flock uniformity by providing a better

nutrient supply to late maturing birds and by

enabling early maturing birds to obtain

sufficient calcium for eggshell production of

the first eggs.

Crude Fibre

Crude fibre, sometimes described as insolu-

ble NSP*, may not have nutritional values

for poultry, but it does have other benefits

for a healthy and stable digestive physiol-

ogy. Used in the second half of the rearing

period, it can positively influence the devel-

opment of the digestive tract, the crop size

and the appetite of pullets. This is beneficial

for young layers, especially at the start of

production, when the appetite of the birds

is sometimes not sufficient enough to meet

their nutrient demands.

The tool has been proven to be very

beneficial under varying feeding situations

in a lot of countries. This is the reason

for the implementation of a minimum

recommendation of crude fibre (5–6%) in

the developer feed for



Cereals and their by-products (e.g. bran) or

oil seed by-products (e.g. meal of sunflow-

ers or rapeseed), can be used as a source of

crude fibre. DDGS** can be used as a source

of crude fibre as well. Other raw materials,

which are rich of crude fibre, may be used if

available, but only as long as their inclusion

does not reduce the energy level of the diet.

With a classical corn-soy diet, the recom-

mended crude fibre content can hardly be

achieved. In such cases, other feed ingredi-

ents must be used.

for special use.
