Problems solved by technology

[0006] In view of the common use of feed similar to the adult shrimp stage in the current shrimp breeding period, its nutritional imbalance, poor food attraction, etc., coupled with insufficient consideration of the impact of salinity or temperature stress in the coarsening stage, these may easily lead to slow growth of shrimp seedlings , weak disease resistance and low survival rate

Embodiment 1

[0025] Embodiment 1 provides a kind of special health feed for insect-derived shrimp seedlings, which comprises the following ingredients in parts by weight:

[0026] Black soldier fly extract 17.5%, fish meal 7%, peanut meal 20%, flour 25%, mixed oil (soybean oil and fish oil 2:1) 2.5%, soybean meal 13%, corn meal 15%.

[0027] Among them, the extraction method of the black soldier fly extract is as follows: add distilled water to the black soldier fly oil-removing insect dry powder according to the solid-liquid ratio (g / mL) of 1:10, stir and mix well, and then press the enzyme-to-substrate ratio (enzyme / insect dry powder ) at a mass ratio of 6.5:100 by adding complex enzymes (papain, protease from Bacillus subtilis, flavor protease and chitosanase 1:1:1:1), adjust the pH to 7.5 with 1 mol / L NaOH solution, and place In a constant temperature water bath, the enzyme was hydrolyzed at 52 °C for 4 h. After the enzyme hydrolysis, it was centrifuged at 6500 r / min for 25 min. The fi...

Embodiment 2

[0031] Embodiment 2 provides a kind of special health feed for insect-derived shrimp seedlings, which comprises the following ingredients in parts by weight:

[0032] Black soldier fly extract 15%, fish meal 5%, peanut meal 15%, flour 28%, mixed oil 2%, soybean meal 15%, corn meal 10%.

[0033] Among them, the extraction method of the black soldier fly extract is as follows: add distilled water to the black soldier fly deoiling powder (the deoiling method is the same as in Example 1) at a solid-to-liquid ratio (g / mL) of 1:10, stir and mix, and then Add compound enzymes (papain, Bacillus subtilis protease, flavor protease and chitosanase 1:1:1:1) at a mass ratio of 6.5:100 (enzyme / insect dry powder) and use 1 mol / L Adjust the pH of the NaOH solution to 7.5, place it in a constant temperature water bath, and enzymolyze it at 52 °C for 4 h. After enzymolysis, centrifuge it at 6500 r / min for 25 min. Collect the filtrate for rotary distillation concentration and vacuum freeze-dryin...

Abstract

The invention belongs to the technical field of shrimp feed, and particularly relates to a special insect-derived health-care feed for shrimp fry. The health-care feed comprises the following components in parts by weight: 15-20% of black soldier fly dry powder, 5-10% of fish meal, 15-25% of peanut meal, 10-28% of flour, 2-5% of mixed oil, 5-15% of soybean powder and 10-25% of corn flour. The special health-care feed for shrimp fry can enhance the anti-stress capability of shrimp fry, improve the growth speed and improve the survival rate. The growth experiment of penaeus vannamei fry shows that the health-care feed not only can promote the growth of shrimp fry, but also can improve the survival rate of the shrimp fry. The salinity stress experiment, the temperature stress experiment and the desalination standard thickening experiment of the penaeus vannamei fry show that the health-care feed can improve the stress capacity of the penaeus vannamei fry on salinity and temperature change, thereby improving the survival rate of the fry in the desalination standard thickening stage and improving the economic benefit of shrimp fry culture.

Description

technical field [0001] The invention belongs to the technical field of shrimp feed, and in particular relates to a special health feed for insect-derived shrimp seedlings. Background technique [0002] Insects are the biological group with the largest variety and population in the animal kingdom, and their biomass exceeds the sum of the biomass of all other animals (including humans). Nutrients with large content in insects include protein, amino acid, fatty acid and chitin / chitosan, etc. In addition, some vitamins, mineral components and trace elements are also rich. At the same time, insects have the characteristics of efficient growth and reproduction ability and tenacious vitality, short reproductive generations, high reproductive index, low feeding cost, high conversion rate of organic matter, and easy feeding. A large number of insect products can be obtained in a short period of time, and the degradation products will not pollute the environment. Therefore, the deve...
