Problems solved by technology

However, at present, seaweed resources are limited and the price is high. If it is produced according to the original formula, it will increase the cost of cultivation
In the original formula, soybean meal is one of the sources of vegetable protein, and its proportion is not large. The main reason is that soybean meal contains a variety of enzyme inhibitors and oily substances. If the proportion is too high, sea cucumbers will have indigestion and loose stools, which will affect the quality of food. Sea Cucumber Survival and Growth
This also restricts the use of soybean meal as sea cucumber feed

Embodiment Construction

[0019] Specific embodiments of the present invention will be described below.

[0020] 1. Preparation of Aspergillus niger spore suspension:

[0021] Inoculate the preserved and rejuvenated Aspergillus niger fungus strains on the PDA medium by punching holes, and cultivate them at 28°C for 3 days. After the hyphae cover the entire plate, rinse the spores on the medium with sterile water A suspension of Aspergillus niger spores (i.e. fungal seed liquid) was obtained.

[0022] Koji fermentation:

[0023] Take a certain amount of soybean meal, add water according to the ratio of material to water 80%, mix well, autoclave at 121°C for 20min, and cool to room temperature. Put it into a fermentation container (sterile), insert the Aspergillus niger spore suspension (10% v / w inoculum), put it in a 31°C incubator, and cultivate it for 2 days. During the cultivation process, stir once every 24 hours and add sterile water (replenish the lost water according to the water content to ma...

Abstract

The present invention discloses a sea cucumber compound feed. The sea cucumber compound feed is characterized in that the compound feed is prepared from the following raw material ingredients in mass percentages: 16-40% of alga, 35-45% of sea mud, 2.7-27% of compound fermented soybean meal, 3-5% of fish meal, 3-5% of shell powder, 1-3% of yeast powder, 0.1-1% of multivitamin and 0.1-1% of polysaccharide. The sea cucumber compound feed is prepared by using the fermented soybean meal to replace a part of the alga, can the reduce farming costs, at the same time can also improve the quality of feed, and lower the feed conversion rates.

Description

technical field [0001] The invention relates to the field of sea cucumber cultivation, in particular to a sea cucumber compound feed. Background technique [0002] The body wall of sea cucumber is rich in collagen and proteoglycans, and has high medicinal and edible value. It is an important treasure of my country's seafood economic resources and has become one of the important industries of mariculture. With the rapid development of sea cucumber farming, the demand for feed is also increasing. In the traditional sea cucumber feed, the seaweed whose main function is to attract food and provide nutrition accounts for a large proportion, generally between 40% and 50%. However, at present, seaweed resources are limited and the price is high. If it is produced according to the original formula, the cost of cultivation will be increased. In the original formula, soybean meal is one of the sources of vegetable protein, and its proportion is not large. The main reason is that soy...
