The invention relates to a feed for ducks treated to be as raw materials of roast ducks. The feed is prepared from the following raw materials in percentage by weight: 55-65% of corn, 6-16% of
soybean meal, 0-3% of
fish meal, 5-10% of flour, 2-5% of
peanut meal, 2-5% of corn
protein powder, 2.5-3.2% of
vegetable oil, 0.6-1.2% of
calcium hydrogen phosphate, 1.5-1.8% of stone
powder, 0.30% of
sodium chloride, 0.7-1.5% of amino acids, 0.03% of special vitamins for meat ducks, 0.25% of composite trace elements, 0.02% of a complex
enzyme preparation and 0.03% of a green
feed additive. A preparation method of the feed comprises the following steps of (1) performing links of receiving raw materials and performing warehousing; (2) performing the link of mixing ingredients; (3) performing the link of performing
granulation; and (4) performing the link of cooling the feed and packing the cooled feed. The feed is good in color, low in
powder containing rate, consistent in granule length, good in
hardness, and good in
food consumption of meat ducks; after the meat ducks eat the feed, the
growth speed is high, the meat ducks can become full-grown and ready for slaughter in advance, the
body weight is large, and the feed conversion rate is low; the
deposition rate of
subcutaneous fat of the meat ducks at a later stage is high, and the fatness is good; after the meat ducks are slaughtered, the yield of ducks treated to be as raw materials of the roast ducks is high, the hair cleanness is good, and the skins are bright and white; when the roast ducks are made, the meat quality is fine and smooth in mouth feel, and the
flavor is good; and the feed is green and safe.
