Description

Composite premix for aquatic products and preparation method thereof

Technical Field

The invention relates to the field of production of aquatic premix, in particular to a compound premix for aquatic products and a preparation method thereof.

Background

The aquatic products are one of foods which are popular with people, and the aquaculture brings good economic benefit to fishermen. However, the aquatic farming industry has been severely hit in recent years by the development of diseases such as bacteria and the like due to the deterioration of the farming environment. In particular to the problems of low immunity, slow growth, severe morbidity, low survival rate and the like of fish and shrimp organisms, which influences the healthy development of the aquaculture industry. The aquatic feed is used as one of the most important production data (accounting for 50-70% of the total cost) in aquaculture, and the quality performance of the aquatic feed has important influence on immunity and disease resistance, growth speed, feed coefficient, cultivation survival rate, cultivation benefit and the like of fish and shrimp organisms.

The aquatic products can not be generated autonomously, so that the aquatic products grow slowly, and the income of the breeders is influenced.

2) Mixing and stirring ferrous sulfate, manganese sulfate and zinc sulfate to form a small material (II) for sealing and preserving;

3) Glucose is mixed with the small material (I) and the small material (II) and stirred to form the product.

In summary, the invention has the following beneficial effects: the premix disclosed by the invention can obviously improve the production speed of the product.

Detailed Description

The present embodiment is only for explanation of the present invention and is not to be construed as limiting the present invention, and modifications to the present embodiment, which may not creatively contribute to the present invention as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present invention.

Example 1: the compound premix for the aquatic products is characterized in that a carrier is glucose, and each kilogram of premix contains the following components:

vitamin a:100 ten thousand IU

Vitamin D3:100 ten thousand IU

Vitamin E:10IU

Vitamin K:1.2g

Vitamin B1:4

Vitamin B2:6

Vitamin B6:8

Nicotinic acid: 20g of

Calcium pantothenate: 8g

Folic acid: 300mg of

Biotin: 200mg

Ferrous sulfite: measured as ferrous iron 10g

Manganese sulfate: measured as manganese 10g

Zinc sulfate: 10g of zinc.

Experiment: the formulations according to examples 1-7 were prepared as follows. A preparation method of a compound premix for aquatic products comprises the following steps: 1) Mixing vitamin A, vitamin D3, vitamin E, vitamin K, vitamin B (B1, B2, B6), nicotinic acid, folic acid, calcium pantothenate and biotin uniformly by adopting a drum mixer for stirring for 15min to form a small material (I) for sealing and storing for later use;

2) Mixing and stirring ferrous sulfate, manganese sulfate and zinc sulfate by adopting a rotary drum mixer for 15min to form a small material (II), and sealing for later use;

3) Glucose, the small materials (I) and (II) are mixed and stirred by a single-blade mixer for 15min to form the product. The mixing uniformity of the final product is 3.46%, the standard value is less than or equal to 5%, and the mixing uniformity meets the requirement.

For example, 2kg of the compound premix is added per ton of the cultured Luo Shizhao shrimps, and no compound premix is added in the control group. 10000 shrimp larvae are respectively thrown into each experimental area aiming at the examples 1-7, 1000 shrimp larvae are taken to measure the average weight of 3.26g, and 1000 shrimp larvae are randomly taken after 4 months to weigh and average.

By comparing example 1 with examples 6 and 7, the weight gain of the shrimp larvae is fastest when the content ratio of B1, B2 and B6 is 2:3:4.

For example, the compound premix is added for 2kg per ton for culturing Luo Shizhao shrimps. 10000 shrimp larvae are respectively thrown into each experimental area aiming at the examples 1-7, 1000 shrimp larvae are taken to measure the average weight of 3.26g, and 1000 shrimp larvae are randomly taken after 4 months to weigh and average.

By comparing example 4 with example 8 and comparing examples 5 and 9, the weight gain effect is better when the content ratio of ferrous sulfite, manganese sulfate and zinc sulfate is 1:1:1 under the condition of the other amounts being unchanged.

By comparing example 2 with examples 10-11, the weight gain effect is better when the content ratio of vitamin A to vitamin D is 1-1.2:1 under the condition of the other amounts being unchanged.

From example 2, compared with comparative example 1, the weight gain of the shrimp was slowed down when vitamin a and vitamin D3 were deficient. From the comparison of example 2 with comparative example 2, the weight gain of the shrimp was slowed down when vitamins B1, B2, B6 were absent. From example 2, in comparison with comparative example 3, the weight gain of the shrimp was slowed down when calcium pantothenate, folic acid, nicotinic acid, biotin were absent. In comparison with comparative example 3, in example 2, the weight gain of the shrimp was reduced when iron sulfite, manganese sulfate and zinc sulfate were deficient.
