Abstract

The invention relates to the technical field of preparation of aquatic product feeds and discloses a puffed feed for spotted silver carps in a high-density culture mode. The puffed feed comprises the following ingredients in parts by weight: 25-30 parts of 43% soybean meal, 16-20 parts of 200-type rapeseed meal, 5-7 parts of chicken meal, 18-20 parts of wheat flour, 10-15 parts of rice husk, 4-6 parts of coarse bran and 2-3 parts of omnivorous premix. According to the puffed feed, the problem of the existing feeds for spotted silver carp culture that the growth requirements of the spotted silver carps in the high-density culture mode cannot be met is solved.

Description

technical field [0001] The invention relates to the technical field of aquatic feed preparation, in particular to an extruded feed used in high-density breeding of silver carp and a preparation method thereof. Background technique [0002] The stocking density of the existing silver carp culture is generally 50-80 fish / mu, but in order to improve the breeding output and economic benefits, some farmers will adopt a high-density breeding mode to stock the silver carp, such as the 1215 model. In this mode, the silver carp The stocking density reached 120 / mu. However, it can be seen from the existing silver carp breeding technology that the common silver carp feed on the market is basically low-grade powder, which is wasteful in the feeding process and cannot meet the growth needs of silver carp under the high-density culture mode. . Contents of the invention [0003] Based on the above technical problems, the present invention provides an extruded feed for high-density carp...
