Embodiment Construction

[0035] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0036] On the basis of laboratory research on the use of corn gluten meal instead of fish meal in Penaeus vannamei compound feed, formula 1 and formula 2 feeds with a corn gluten meal consumption of 8% were prepared, and the amount of fish meal replaced was 23.5% and 25.0% respectively. The composition of the feed ingredients is shown in Table 1:

[0037] Formulation of table 1 feed

[0038]

[0039] Feed of the present invention can be made by following method:

[0040] (1) According to the weight percentage of the total weight of the feed, 20-26% of white fish meal, 10-13% of soybean meal, 4-10% of peanut meal, 4-7% of yeast, 5-10% of corn gluten meal, and 7-10% of meat powder 11%, rice bran 0-2% raw materials are coarsely crushed;

Abstract

The invention discloses a white-leg shrimp compound feed with partial fish meal replaced with corn protein powder. Metered by the total weight of the feed, the white-leg shrimp compound feed comprises the following components in percentage by weight: 20-26% of white fish meal, 10-13% of soybean meal, 4-10% of peanut meal, 4-7% of yeast, 5-10% of corn protein powder, 7-11% of meat meal, 0.5-1.5% of squid liver paste, 26-31% of flour, 0-2% of rice bran and the like. The invention simultaneously discloses a preparation method and application of the white-leg shrimp compound feed. The corn protein powder is prepared by the steps of: mixing corn steep liquor obtained from the corn starch production with waste liquid generated after the production of lysine and glutamic acid according to a certain proportion, and refining through the processes of enzymolysis, concentration, drying and the like. The use of the corn protein powder is not only beneficial to environmental protection but also beneficial to the reduction of fish meal consumption. In the invention, the used raw materials are easy to obtain, the production process is simple and the quality is stable.

Description

technical field [0001] The invention relates to a feed, in particular to a Penaeus vannamei compound feed which uses corn gluten meal instead of part of the fish meal, its preparation method and application, and belongs to the field of aquatic animal nutrition and feed science in aquaculture. Background technique [0002] The protein source of aquatic feed mainly comes from fishmeal, while the amount of self-produced fishmeal in my country is very small, and a large amount of fishmeal is imported. It is the largest consumer market of fishmeal in the world, and the actual use of fishmeal accounts for nearly 50% of the total amount of fishmeal used in global aquafeeds. In recent years, affected by the decline of global fishery natural resources, the world's fishmeal production has declined year by year. At present, the proportion of fishmeal used in aquatic feed in our country is high and the waste phenomenon is relatively serious, so it has become a new source of pollution. ...
