lating to an energy requirement when
using a formulation software.
Previous research at Kansas State
University demonstrated that when diets
were balanced by energy for every 1%
added fat, PDI was reduced by 10% to
14%. However, it is important to keep in
mind that this response will depend on
pelleting parameters such as conditioning temperature and time, die specifications, production rate, etc.
In addition to added fat, proteins and
starch are altered during the conditioning

When pelleting
feed, there are many
factors than can
influence subsequent
pellet quality. These
factors must be
considered when
trying to optimize
pellet quality.

and pelleting process and can potentially
lead to changes in binding properties. Diets containing high protein can denature
and plasticize under pelleting conditions
and form a harder pellet, increasing pellet
durability. The influence of protein and
starch on pellet quality is dependent on
their functional properties, with raw protein and pre-gelatinized starch improving
pellet quality compared to denatured protein and native starch.
Pelleted diets containing high amylase
corn that led to increased gelatinized
starch compared to pelleted conventional corn diets at similar processing parameters, but there was no evidence for
improvement in PDI with the increase
in starch gelatinization. Therefore, the
level of starch gelatinization that occurs
during pelleting may not be enough to
influence pellet quality. This leads to the
hypothesis that proteins or the protein
starch interactions may play a larger
role in influencing pellet quality.
This agrees with previous research
that demonstrated an improvement in
PDI when crude protein content was increased by 3.9% or 4.7%.
Pelleting feeds plays an important role

Pelleting feed plays an important role in
optimizing animal performance.

in optimizing animal performance and
improving feed handling characteristics
like increased flowability and bulk density with reduced ingredient segregation.
Improving pellet quality has a positive
influence on the observed response on
swine and poultry performance.
When pelleting feed, there are many
factors that can influence subsequent
pellet quality. These factors must be considered when trying to optimize pellet
quality. However, actions taken to improve pellet quality come at a cost via increased ingredient cost, increased energy
consumption, or reduced production rate.
Therefore, it is important to calculate
the overall economic impact when determining the optimal pellet quality and
how to achieve it.
