The invention relates to a method for preparing muscovy duck feed. The muscovy duck feed comprises the following compositions in percentage by weight: 4 to 6 percent of
soybean meal, 2 to 6 percent of
maize meal, 10 to 12 percent of
sorghum powder, 6 to 8 percent of malt
powder, 14 to 18 percent of white fishmeal, 4 to 6 percent of freshwater
snail meal, 6 to 8 percent of
freshwater shrimp meal, 8 to 10 percent of rice
bran, 4 to 6 percent of chicken
blood meal, 3 to 5 percent of salvinia
meal, 6 to 10 percent of grass seed meal, 2 to 4 percent of
fish liver oil, 1 to 3 percent of salt, 1 to 3 percent of
psoralea, 2 to 4 percent of
pinellia, 1 to 3 percent of unibract fritillary
bulb, 2 to 4 percent of
cyperus rotunus, 1 to 3 percent of
mulberry leaf and 1 to 3 percent of
cassia seed. According to the proportion, the powders are taken out, put in a
multiplex stirrer and stirred; after being taken out, the powders are put in a ring mould type
pulverizer and pulverized; then, the powders are taken out, put in a drier and dried; after being taken out, the powders are put in a ring mould type swelling
machine and swelled; after being taken out, the powders are transferred to a ring mould type hard granulator to generate precipitated hard granular feed; then the feed is sifted by a 80-mesh
sieve; and the weight of each granule is 0.2
gram, namely the feed can be sealed and packaged according to the needed weight.
