The invention discloses an hydrolyzed puffing
forage and preparation method thereof. The method comprises: choosing the plants with high wood-
fiber content such as
straw, cereal shell, corn core, coconut cover, palm leaf, wood / bamboo scraps,
bagasse, herbage
rhizome and
weed, performing
hydrolysis and puffing treatment for destroying the encapsulation effect of
lignin to
hemicellulose and
cellulose, degrading the
hemicellulose and
cellulose into
small molecule soluble
sugar, and continuously extruding and puffing by force. The continuous forced feeding and discharging technology realizes stable transitions between different pressures. The invention increases
digestion rate greatly, can substitute part of corn and wheat
bran, and can be prepared into complete feeds for different birds or animals in different growth stages by adding
protein forage, salt,
vitamin, mineral elements and aminating agent. The hydrolyzed puffing
forage of the present invention has similar
digestion rate with the conventional grain forage and sweeter taste, reduces cost greatly, alleviates the grain shortage difficulty, and is suitable for pig, cattle, sheep, chicken, duck,
goose, rabbit and specially raised pets.
