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 algae powder, 10 to 20 percent of kelp powder, 5 to 15 percent of fish meal, 10 to 30 percent of bean pulp, 5 to 10 percent of zeolite powder, 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 field of feed technology, and relates to a novel nutritional formula of sea cucumber complete compound feed and a preparation method. Background technique [0002] The sea cucumber is fragrant and soft, contains high protein, low fat, and does not contain cholesterol. It is nutritious and has medicinal value. It 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 of marine aquaculture in Liaoning, Shandong, and Hebei in my country. In the process of sea cucumber breeding, whether there is a suitable feed is directly related to the success or failure of seedling breeding and the breeding effect. It is urgent to develop suitable bait and artificial feed for sea cucumbers. Feed problems are becoming an important potential factor affecting the development of sea cucumber breeding. [0003] However, research on the nutritional requ...
