Embodiment 1

[0020] Step 1: Feed raw materials are pretreated, dried until the water content is not higher than 15%, and coarsely crushed to 100-200 mesh; wherein, the feed raw materials are kelp powder, fish meal, sea mud, shell powder, and compound vitamins and minerals.

[0021] Step 2: Weigh 5kg of kelp powder, 1kg of fish meal, 3kg of sea mud, 0.75kg of shell powder, and 0.25kg of multivitamins and minerals;

[0022] Wherein, the multivitamins and minerals are the same as those of the basal feed of the prior art in terms of added ingredients and quantity. Provide a kind of preferred mode here, described multivitamin and mineral composition are (mgg -1 ): thiamin hydrochloride0.5, riboflavin1.0, nicotinic acid0.75, pyridoxine hydrochloride 1.5, vitamin B 12 0.05, calcium pantothenate 10, L-ascorbyl-2-monophosphate-Mg50, choline chloride200, menadione2, retinol acetate 0.6, Vitamin E 10, α-cellulose 723.6; MgSO 4 -7H 2 O 100,ZnSO 4 -7H 2 O 3 , CoCl 2 -6H 2 O 1,MnSO 4 -H 2 O 1,...

Embodiment 2

[0029] Step 1: Pretreatment of feed raw materials, drying until the water content is not higher than 15%, and coarsely crushing to 100-200 mesh;

[0030] Among them, the feed raw materials are kelp powder, fish meal, sea mud, shell powder and complex vitamins and minerals.

[0031] Step 2: Weigh 5.5kg of kelp powder, 1kg of fish meal, 2.5kg of sea mud, 0.8kg of shell powder, and 0.2kg of multivitamins and minerals;

[0032] Step 3: After weighing, the raw materials are placed in a mixer and fully stirred, and mixed to obtain the basic feed;

[0033] Step 4: Weigh 0.01kg of sodium alginate and 0.01kg of urea, dissolve them together with 0.25kg of the above-mentioned mixed bacteria powder in 0.35kg of sterile water with a salt content of 1%, and mix the resulting solution into the basic feed; (it can also be dissolved alginate and urea, added to the basal feed along with probiotics).

[0034] Wherein, the mixed bacteria powder is the mixed bacteria powder of Bacillus flexus, B...

Embodiment 3

[0038] Healthy sea cucumbers of similar size were selected as experimental subjects, weighing 5±0.3g. Investigate the difference between the above-mentioned invention fermented feed and common sea cucumber feed on the growth performance of sea cucumber. Among them, the common sea cucumber feed is produced by Dalian Sym Bioengineering Co., Ltd., and its components are 45% eel algae powder, 25% sea mud, 5% fish meal, 20% soybean meal powder, 2% vitamins and minerals, and 3 wheat starch. %. Before the start of the experiment, carry out adaptive temporary breeding. All breeding boxes are aerated for 24 hours, using a flowing water system, avoiding light, changing 30% of the breeding water every day, and sucking low sewage once a week. During the whole experiment, dissolved oxygen ≥ 6mg / l, The water temperature is maintained at 16-18°C, the pH is 7.9-8.1, and the salinity is 30-32ppt. The above-mentioned two feeds were fed at fixed times every day, and the feeding amount was 5% o...

Abstract

The invention discloses a preparation method of a stichopus japonicus microorganism degumming kelp fermented feed. The preparation method comprises the steps: adding microecologics capable of degrading sodium alginate in kelp in a basal feed with the kelp as a main raw material and fermenting, wherein the basal feed comprises the following components in percent by weight: 45-55 percent of kelp meal, 5-15 percent of fish meal, 25-35 percent of sea mud, 5-10 percent of shell powder and 1-5 percent of decavitamin and mineral substances, and the amount of the microecologics is 1-5 percent of the weight of the basal feed. According to the feed disclosed by the invention, the digestibility and utilization rate of stichopus japonicus to the kelp can be remarkably increased, the nutrition and energy level required by the growth of the stichopus japonicus are met, the problem of deficiency of sargassum thunbergii resources of an excellent bait for the stichopus japonicus is effectively solved; and the feed has a raw material value-added function, and is low in cost. Under a better ecological condition, the feed is capable of reducing the damage of the residual bait to a culturing water body, promoting the immunity of the stichopus japonicus to a certain extent, and preventing antibiotics from being used.

Description

technical field [0001] The invention relates to the technical field of feed, and more specifically relates to a method for preparing a low-cost and environment-friendly Apostichopus japonicus microorganism degummed kelp fermented feed with the function of adding value to raw materials. Background technique [0002] At present, sea cucumber is the economic species of mariculture with the highest output value in my country. According to statistics, in 2011, the national annual output value of sea cucumber exceeded 30 billion. As the mode of sea cucumber farming has shifted from extensive to intensive, research on sea cucumber feed has attracted more and more attention from industry insiders. The feed cost of intensive aquaculture accounts for more than 70% of the entire farming cost, while sea cucumber feed and The nutritional problem has always been a bottleneck restricting the healthy development of the sea cucumber aquaculture industry. Among them, the lack of high-qualit...
