[0003] Since the bait needed for artificial cultivation of sea cucumbers mainly feeds on algae such as benthic diatoms, sargassum, and sargassum, the variety is single, and it is easy to cause nutritional deficiencies. Meet the needs of sea cucumber seedlings and growth
Some manufacturers use sea mud, rotten straw filtrate, benthic diatoms, etc. to feed sea cucumbers, which have a certain effect, but because the water quality is easy to deteriorate, sea cucumbers are prone to fester disease, and the survival rate is low
It is difficult to fully meet the nutritional needs of sea cucumbers at each growth stage when using this kind of feed in production, the breeding effect is poor, and it has no general promotion value

[0034] The special compound feed for juvenileginseng produced from alfalfa contains the following components, according to the weight percentage of each component: 25% alfalfa, 14% soybean meal, 8% peanut meal, 10% corn flour, 1% gluten, seaweed 12% powder, 5% fish meal, 15% scallop powder, 5% shrimp powder, 2% yeast, 2% commercially available multivitamins for aquatic products, and 1% commercially available special minerals for aquatic products.
[0035] The alfalfa used is alfalfa hay powder, and its preparation process: the fresh alfalfa grass before the flowering period is harvested and broken into small pieces with a length of 2cm to 3cm, and immediately sent to the dryer by a conveyor, dried at a high temperature of 800°C to 1000°C, and then dried at a high temperature of 800°C to 1000°C. The water content of fresh grass is reduced to 8-15% in a few seconds, and the most suitable range is 10-12%. The dried high-quality...
[0048]The difference between this example and Example 1 is that the percentages by weight of the components in the raw materials are: 28% alfalfa meal, 16% soybean meal, 8% peanut meal, 10% corn flour, 4% gluten, seaweed 8% powder, 3% fish meal, 10% scallop powder, 8% shrimp powder, 2% yeast, 1.5% commercially available multivitamins for aquatic products, and 1.5% commercially available special minerals for aquatic products;
[0049] Its manufacturing method is different from embodiment 1 in that:
[0050] 3) Superfinely pulverize the coarsely pulverized material to more than 120 mesh;
[0051] 4) Use a 120-mesh sieve to sieve the ultra-finely pulverized material, and the material under the sieve is the finished product, which enters the packaging process.
Embodiment 3
[0053] The difference between this example and Example 2 is that the percentages by weight of the components in the raw materials are: 30% alfalfa meal, 11% soybean meal, 14% peanut meal, 5% corn flour, 5% gluten powder, seaweed 3% powder, 5% fish meal, 12% scallop powder, 4% shrimp powder, 6% yeast, 3% commercially available multivitamins for aquatic products, and 2% commercially available special minerals for aquatic products.

Abstract
The invention relates to a sea cucumber feed prepared from alfalfa and a preparation method thereof. The sea cucumber feed comprises the following components in percentage by weight: 25-36 percent of alfalfa, 10-22 percent of bean pulp, 8-14 percent of peanut meal, 4-15 percent of corn meal, 1-8 percent of glutenmeal, 0-12 percent of seaweed meal, 2-8 percent of fish meal, 8-15 percent of scallop skirt meal, 2-15 percent of shrimp meal, 2-10 percent of yeastpowder, 1-4 percent of complex vitamins special for aquiculture and 1-2 percent of mineral substances special for aquiculture. The preparation method comprises the following steps of: (1) weighing the raw materials according to the weight percentage of each component; (2) mixing and roughly crushing the weighed raw materials; (3) carrying out ultramicro crushing on the roughly-crushed materials; and (4) selecting a sieve according to the body size of the sea cucumbers and sieving the materials. The preparation method has a scientific and reasonable formula and a simple and convenient process; and the prepared feed has an appropriate calcium-phosphorus rate and has the effects of remarkably promoting the growth of the sea cucumbers, shorting the culturing cycle and improving the stress resistance capability and the capabilities of saving a great amount of seaweed resources and reducing the pollution to the water body.
Description
technical field [0001] The invention relates to a feed for aquaculture, in particular to a feed for sea cucumber produced from a terrestrial plant alfalfa and a manufacturing method thereof. Background technique [0002] Sea cucumber is favored by consumers because of its unique nutritional value, and the market demand has risen sharply. This market situation in short supply has given birth to the rapid development of sea cucumber artificial breeding. [0003] Since the bait needed for artificial cultivation of sea cucumbers mainly feeds on algae such as benthic diatoms, sargassum, and sargassum, the variety is single, and it is easy to cause nutritional deficiencies. Meet the needs of sea cucumber seedlings and growth. Some manufacturers use sea mud, rotten straw filtrate, benthic diatoms, etc. to feed sea cucumbers, which have a certain effect. However, because the water quality is more likely to deteriorate, sea cucumbers are prone to cankers, and the survival rate is lo...
