Embodiment 1

[0032] To prepare the health feed used after Apostichopus aestivus in the south moved to the south, take 40% of sargassum powder, 10% of Ulva powder, 3% of spirulina powder, 15% of high-gluten flour, 19% of fermented soybean meal, 3% of white fish meal, Shrimp powder 2%, oyster shell powder 2.5%, multivitamin 0.4%, compound mineral salt 0.6%, montmorillonite 4%, yeast cell wall 0.5%. According to the preparation process and process of the present invention, each component is coarsely pulverized with a particle size of 40 mesh and then mixed according to the formula ratio. During the mixing process, aging treatment is carried out, and the processed raw materials are cooled, dried, and ultrafinely pulverized to 80 After screening, sealing and packaging, the finished feed is made.

[0033] Take the finished feed for breeding comparison experiment:

[0034] 1. The experiment lasted for 8 weeks and was carried out in the culture enclosure of the outdoor pond. During the experimen...

Embodiment 2

[0039] To prepare the health feed for Apostichopus japonicus aestivation in the south, 35% of sargassum powder, 9% of Ulva powder, 5% of spirulina powder, 17% of high-gluten flour, 18% of fermented soybean meal, 5% of white fish meal, Shrimp powder 3%, oyster shell powder 2.6%, multivitamin 0.4%, compound mineral salt 0.6%, montmorillonite 4%, yeast cell wall 0.4%. The finished feed is prepared according to the preparation process and process described in the present invention, wherein, the particle size of coarse grinding of each component is 35 mesh, and the particle size of superfine grinding of raw materials after treatment is 90 mesh. The finished feed was used for breeding comparison experiments, and the main immune indicators of sea cucumbers were tested:

[0040] 1. The experiment lasted for 8 weeks and was carried out in the culture enclosure of the outdoor pond. During the experiment, the water temperature in the pond dropped from 23.1°C to 11.9°C, and the southward...

Embodiment 3

[0045]The finished feed is prepared according to the raw material formula, ratio, preparation process and process described in Example 1 of the present invention.

[0046] The finished feed was taken for comparative breeding experiments, and the digestive enzyme activity of sea cucumbers was tested:

[0047] 1. The experiment lasted for 8 weeks and was carried out in the PVC tank of the indoor controllable breeding system. During the experiment, the water temperature was controlled at 16°C, the salinity varied from 28.7 to 31.4, the average pH value was 7.9±0.5, and the ammonia nitrogen concentration varied from 0.01 to 0.04mg l -1 ;

[0048] 2. Take sea cucumbers after aestivation in the culture pond for experiment, the initial body weight is 16.79±1.05g, and the culture density is 20ind. / m 3 ;

[0049] 3. The sea cucumbers in the experimental group were fed with the feed of the present invention, and the sea cucumbers in the control group were fed with self-prepared compo...

Abstract

The present invention relates to the field of aquatic feeds and particularly relates to a health-care feed used for a stichopus japonicas southward cultivating after an aestivation. The health-care feed comprises the following compositions and dry matter formula in ratios: 30%-40% of sargassum thunbergii powder, 6%-10% of ulva pertusa powder, 3%-5% of spirulina platensis powder, 15%-18% of high gluten flour, 15%-20% of fermented soybean meal, 3%-5% of white fishmeal, 2%-4% of shrimp powder, 2%-3% of oyster shell powder, 0.3%-0.4% of compound vitamin, 0.5%-0.6% of compound mineral salt, 2%-4% of montmorillonite and 0.3%-0.5% of yeast cell wall. By using a scientific formula proportion and adding active ingredients, the health-care feed gives the stichopus japonicas balanced and special nutrition supply in the critical period of the cultivating. The feed is strong in attractant, good in palatability and high in utilization rate, can significantly accelerate the body constitution recovery of the stichopus japonicas cultivating after the aestivation, and effectively improves the growth rate and rate of the weight of skins to total weight. The main feed raw materials are natural ingredients, and the feed does not produce negative impacts on cultivating water bodies and surrounding waters during the use and is green and environment-friendly products.

Description

technical field [0001] The invention relates to the field of aquatic feed, in particular to a health-care feed used after aestivation of sea cucumbers cultured in the south. Background technique [0002] Sea cucumber is known as the first of the "Eight Treasures of Seafood", and it is a nourishing product with the same source of medicine and food. With the improvement of people's living standards and the change of consumption concept, the market demand of sea cucumber is expanding year by year, and the breeding industry is developing rapidly. Especially in recent years, sea cucumber farming has emerged in the eastern and southern coastal provinces of my country. As a new force in the industry, it has changed the market structure and the direction of industrial development. The so-called southward migration of sea cucumbers refers to the cultivation and production of sea cucumbers in non-traditional sea cucumber production areas and natural habitats along the coast of my cou...
