The use of
maize wet-milling agri-products in poultry feeds depends almost entirely on
the nutritive requirements of the class of bird being fed.
In poultry feeds, Gluten-60 is the agri-product
mostly used. It has a high nutrient
density and concentrated energy value as well as high levels of
biologically available even to young chicks). It also includes xanthophyll, which is the
yellow pigment that
makes it desirable in diets for broilers and layers. Research
shows that broilers and layers do not discriminate between feeds containing up to
percent Gluten-60. Neither is performance reduced at those high levels,
provided that diets are balanced for the essential amino acids
The relations between Gluten-60 and both yolk colour and skin colour are as follows.
Note that for skin colour, 0 is light and 10 is dark.
Skin colour = 2,9 + (0,43 x Gluten-60 inclusion %)
Yolk colour = 6,5 + (0,27 x Gluten-60 inclusion %)
For both skin colour and yolk colour, evaluations were based on the DSM colour fan.
The relatively high levels of linoleic acid (1.32%) in Gluten-60 makes it useful for young
chicks, because they have a high requirement for essential fatty acids.
For Monogastrics,
Gluten-20 has relatively high fibre levels and is therefore restricted
to formulations for laying hens, pullet rearing, and broiler breeders. Levels of between
and 15 percent may be used in balanced diets without affecting feed efficiency
or egg production.
Gluten-60 is very suitable as an ingredient of pig feed and may be included at levels of
up to 8 percent in grower rations.
Gluten-20 can be used at levels of up to 15 percent in pig feeds without suppressing the
conversion ratio or performance of the feed. The availability or quantity of tryptophan
may limit its application, however.
When the amino acid of the diet is balanced,
growing and finishing swine can utilize up to 30 percent in their diets.
