Compound feed for improving flavor and meat quality of grass carp by utilizing fermented silkworm excrement

Abstract

The invention discloses compound feed for improving flavor and meat quality of grass carp by utilizing fermented silkworm excrement, and belongs to the technical field of feed formulas for grass carpbreeding. Preparation methods of fermented silkworm chrysalis and the fermented silkworm excrement comprises the following steps: Step 1, mixing the silkworm chrysalis with soybean meal, mixing the silkworm excrement with peanut bran, wherein the mass ratio of the silkworm chrysalis to the soybean meal is 1: 1, the mass ratio of the silkworm excrement to the peanut bran is 7: 3, and the followingsteps regarding the silkworm chrysalis and the silkworm excrement are carried out separately; Step 2: inoculating microorganisms into the uniformly mixed materials, and adding a carbon source and inorganic salt; and Step 3: carrying out fermentation culture for 24-36 hours, and subjecting fermented products to drying and crushing, thereby obtaining fermented silkworm chrysalis and fermented silkworm excrement, respectively. According to the invention, the grass carp feed contains the fermented silkworm chrysalis capable of improving the growth performance of the grass carp, the fermented silkworm excrement capable of improving the meat quality and flavor of the grass carp and beneficial bacteria capable of reducing the application amount of fish pesticides and antibiotics, so that the grass carp feed can increase economic benefits of farmers, and have a positive effect on promoting the sustainable, healthy and stable development of grass carp aquaculture.

Description

technical field [0001] The invention relates to the technical field of grass carp breeding feed formulation technology, in particular to a compound feed that utilizes fermented silkworm excrement to improve the flavor and meat quality of grass carp. Background technique [0002] Grass carp belongs to the genus Grass carp of Cyprinidae Cyprinidae. Grass carp is commonly known as: grass carp, oil carp, grass carp, white carp, etc. It inhabits rivers and lakes in plain areas, and generally likes to live in the middle and lower layers of water and areas with many aquatic plants near the shore. It is a typical herbivorous fish. Because of its rapid growth and wide source of feed, it is one of the four major domestic fish in freshwater farming in China. [0003] The mulberry fishpond is a traditional three-dimensional ecological agricultural model in the Pearl River Delta region. It has a long history and good comprehensive effects. It is praised by UNESCO as a "model of a virtuo...

Problems solved by technology

[0006] In the past, people used silkworm chrysalis and silkworm excrement extensively, and directly put them into fish ponds to feed fish. However, silkworm chrysalis has a pupa odor, which is not conducive to animal feeding, and it will also accumulate in the carcass, affecting the taste of meat.
