Problems solved by technology

Penaeus vannamei not only needs a good growth environment and scientific management, but also needs nutritionally balanced feed. In recent years, due to the deterioration of the breeding environment, the breeding density has become higher and higher, which makes Penaeus vannamei susceptible to diseases and slow in growth; and due to the existing Penaeus vannamei compound feed has deficiencies such as balanced nutrition, poor food attraction, and poor stability in water, which is also not conducive to rapid and effective feeding of Penaeus vannamei, which further aggravates slow growth, weak disease resistance and low survival rate.
The problem of disease has always been the bottleneck restricting the sustainable development of Penaeus vannamei aquaculture, especially with the rapid development of vannamei aquaculture and the improv...

Embodiment 1

[0015] Example 1 : A special feed additive for Penaeus vannamei, made of the following raw materials by weight: 8 parts perilla, 5 parts acacia, 6 parts green peel, 3 parts cinnamon sticks, 3 parts anise, 6 parts white peony, vitamin C 0.02 Parts, 0.001 parts of vitamin K, 25 parts of carrier. The preparation method is as follows: Weigh each raw material in parts by weight, first mix the weighed six kinds of traditional Chinese medicine including perilla, acacia, green bark, cinnamon twig, anise, white peony, and crush to about 40-60 mesh, and then crush The obtained traditional Chinese medicine powder is mixed with the weighed vitamin C and K and the carrier, stirred evenly, and packaged.

Embodiment 2

[0016] Example 2 : A special feed additive for Penaeus vannamei, made from the following raw materials by weight: 6 parts of perilla, 7 parts of acacia, 7 parts of green peel, 4 parts of cinnamon sticks, 2 parts of anise, 5 parts of white peony, vitamin C 0.02 Parts, 0.001 parts of vitamin K, 22 parts of carrier. The preparation method is as follows: Weigh each raw material in parts by weight, first mix the weighed six kinds of traditional Chinese medicine including perilla, acacia, green bark, cinnamon twig, anise, white peony, and crush to about 40-60 mesh, and then crush The obtained traditional Chinese medicine powder is mixed with the weighed vitamin C and K and the carrier, stirred evenly, and packaged.

Embodiment 3

[0017] Example 3: Aquaculture test

[0018] In an aquaculture base in Zhoushan, Zhejiang, we selected Penaeus vannamei cultured in seawater cages as the test subjects, and selected 10 cages as the test subjects. The number of prawns in each cage is basically the same, and the converted culture density is 6 Ten thousand tails / mu (high-density farming), and the same batch of shrimp larvae stocked in the same period, using the same farming mode for management. Group 1 is the control group, and 1% corn gluten meal is added during the production of compound feed; groups 2-3 are experimental groups, and 1% of the vannamei prawns of Examples 1 and 2 are added during the production of compound feed. Special feed additives; groups 4-5 are comparative test groups. 1% of the feed additives of comparative test examples 1 and 2 are added during the production of compound feed. The breeding starts when the body length is about 3cm, and the breeding is 35 days. Record the breeding The average...

Abstract

The invention relates to a special feed additive for a South American white shrimp. The special feed additive is prepared from the following raw materials by weight: 5 to 10 parts of perilla, 5 to 8 parts of Chinese honey locust, 5 to 7 parts of green tangerine peel, 2 to 4 parts of cassia twig, 2 to 3 parts of aniseed, 3 to 7 parts of white peony root, 0.02 part of vitamin C, 0.001 part of vitamin K and 20 to 25 parts of a carrier. 0.5 to 1.2% of the special feed additive for the South American white shrimp provided by the invention is added into a conventional mixed feed for the shrimp for breeding of the South American white shrimp. With the special feed additive for the South American white shrimp provided by the invention, economic benefits in breeding of the shrimp are obviously improved, occurrence of diseases during breeding of the shrimp is substantially reduced, the survival rate of the shrimp is increased by 19 to 22%, growth of the shrimp is promoted, and quality of the shrimp is enhanced.

Description

technical field [0001] The invention relates to a feed additive for aquaculture, in particular to a special feed additive for Penaeus vannamei. Background technique [0002] Litopenaeus vannamei belongs to the shrimp family, and its scientific name is Litopenaeus vannamei. It is one of the three largest species of farmed shrimp in the world. Penaeus vannamei is large in size, thin in shell and fat in body, with a meat yield of over 65%. The meat is tender, delicious, and rich in protein. It is popular in domestic and foreign markets and has high economic value. It can reach the listed specifications; low nutritional requirements, strong disease resistance, wide salt range (0~45%), can be used in various breeding methods such as pure fresh water, brackish water and sea water, from natural sea areas to freshwater ponds It grows without geographical limitations, and has the advantages of high temperature resistance and strong disease resistance. It is a high-quality variety of...
