Embodiment 1
[0019] Step 1 Feed raw materials are pretreated, dried until the water content is not higher than 15%, and coarsely crushed to 40-60 mesh.
[0020] Step 2 Weigh 2.5 kg of seaweed powder, 2.2 kg of kelp powder, 2.3 kg of fish meal, 1.2 kg of soybean meal, 0.5 kg of sea mud, 0.5 kg of corn flour, 0.2 kg of shell powder, and 0.1 kg of multivitamins and minerals, and place them in a blender. Stir and mix to obtain the basic feed.
[0021] In step 3, weigh 0.5 kg of cassava a-starch and add it to the basic feed obtained in step 2, place it in a mixer, and stir and mix well.
[0022] In step 4, the coarse feed powder obtained in step 3 is processed by using a high-energy vibrating mill capable of producing micro-shearing. The processing time is 10 minutes, and the particle size is 200-300 mesh as detected by a laserparticle size analyzer.
[0023] Step 5: Add water according to the ratio of 1:1 by weight, mix thoroughly, repeatedly extrude through a plodder, and dry at no higher t...

Abstract
The invention relates to an environment-friendly sea cucumber streak feed and a preparation method thereof, and belongs to the technical field of feed. The feed comprises the following raw materials in percentage by weight: 20 to 35 percent of algaepowder, 10 to 20 percent of kelppowder, 5 to 15 percent of fish meal, 10 to 30 percent of bean pulp, 5 to 10 percent of zeolitepowder, 5 to 10 percent of corn meal, 5 to 10 percent of shell powder, 1 to 3 percent of composite vitamin and mineral substance, and plant immune reinforcing agent and microbial preparation added as required. The preparation method comprises the following steps of: pre-treating and drying the raw materials of the feed, coarsely crushing the raw materials to 40 to 60 meshes, then adding a proper amount of auxiliary agent into the coarse powder, treating the mixture by micro shearing-auxiliary agent technology to obtain an ultra-micro powder raw material of 200 to 300 meshes, adding water into the ultra-micro powder raw material in a weight ratio of 1:1, mixing the raw material and the water uniformly, extruding the mixture into streaks, and drying at the temperature of 20 DEG C to obtain the streak feed with different lengths and widths. The feed is suitable for aquatic product culture such as sea cucumber and the like, and has the advantages of environmental protection, long soaking time, low nutrient loss, strong trapping property, quick weight increment and excitability reduction.
Description
technical field [0001] The invention belongs to the technical field of feed, and relates to a nutritional formula and a preparation method of a novel sea cucumber full-price compound feed. Background technique [0002] Sea cucumber meat is fragrant, soft and smooth, high in protein, low in fat, free of cholesterol, rich in nutrition and has medicinal value, and has the same effect of medicine and food. In 2009, the national annual output value exceeded 10 billion yuan, and it has become an important pillar industry for marine aquaculture in Liaoning, Shandong, and Hebei. In the sea cucumber breeding process, whether there is a suitable feed is directly related to the success or failure of the seedlings and the breeding effect. It is imminent to develop a suitable sea cucumber bait and artificial feed. The feed problem is becoming an important potential factor affecting the development of sea cucumber farming. [0003] However, research on the nutritional requirements of sea...
