Example Embodiment

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

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

[0021] The preserved and rejuvenated Aspergillus niger fungus strain was inoculated on the PDA medium by punching, and cultured at 28°C for 3 days. After the hyphae covered the entire plate, the spores on the medium were washed off with sterile water. A suspension of Aspergillus niger spores (ie fungal seed liquid) is obtained.

[0022] Koji fermentation:

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

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...
