The majority of commercial broiler diets have been through
the pelleting process. However, the durability of pellets
can be variable, resulting in levels of fines as high as 50%.
Incidences of high levels of fines in the field are associated
with poor liveweight and FCR. To maximize performance,
the accumulation of fine particles in the feed
should be minimized.
It is important to establish the modern broiler’s response to
high levels of fines. The following two trials, conducted by
Aviagen, tested both extreme levels of fines and levels commonly
seen in the field.
