And how do they work?
The aim should be to kick-start the digestive
system of the young chick as soon as possible. Food
particle size and feed presentation will play a significant role in this. The diets are often in the form
of crumbs or mini pellets and should be highly palatable and dust free.
"Dextrose is included as a source of fast energy,"
Dijkslag said. "We make use of egg powder as a highly
digestible form of protein as well as adapting the amino
acid profile of the diet."
The ideal ratio of total sulphur amino acids to lysine
ratio for young chicks has been the focus of investigations.
By supplying pure amino acids, the chick doesn't have
digest protein before benefiting. Their source may also be
important; for example, those forms of methionine that
are passively absorbed may be particularly suited to the
still maturing gut.

There is a lot of interest in increasing the robustness
of chicks and, as such, producers are testing super prestarters. Many nutritionists, while believing in the aims
of broiler super pre-starters, are not seeing large-scale
commercial use. "Investment also needs to be made
in chick placement and management," Garland said.
"Seeing a benefit at seven days does not always carry
through to slaughter."
Logistically, the use of super pre-starters needs some
consideration. Its specialized nature means a standard feed
mill would not have the specialist raw materials or equipment or expertise necessary to produce such a diet. This
means higher handling costs and coordination with more
than one feed supplier.
