Feed Delivery Systems

Is it profitable to
grind, crush, or soak
When animals fail to chew grain
thoroughly some of the nutritive
value of the feed is lost because
of reduction of surface area
Fineness of grain – why?
Should be ground medium fine
Swine should be ground more finely
Fine grinding takes more energy
700 t0 800 microns
Time and process can make grains less
Wheat and barley ground to fine can be lost
as dust, or cause digestive problems
Rolling vs Grinding
Rolling grains results in a more uniform
particle size which improves digestibility
Rolling grain is more energy efficient
than using a hammer mill or grinder
Advantage of Pellets
Less waste
Less space needed for storage
Animals may eat more feed in pellet
Chopping or grinding hay is only
advisable if it encourages animals to eat
coarse, stemmy portions that might
otherwise be left
100% Concentrate
Is not advisable because of
digestive troubles in animals,
especially ruminants
Cooked Feed
Advantageous when feeding
Field beans
Cooking removes factors that cause
poor performance in swine
Cooking does not increase the
digestibility or feeding value of other
Soaking Feeds
Advantageous when grain with small or
hard kernels cannot be ground or
If soaked too long, fermentation may
take place or mold will grow which
produces toxins
Fermenting of Feeds
Experiments show that this does not
cause any saving in feed or result in
greater production
