Special feed additive for South American white shrimp

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...

AI Technical Summary

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 improvement of intensive farming, as well as the use of artificial feed, large-scale Outbreaks of epidemics and mass deaths, while the traditional methods of disease prevention and control with antibiotics and chemical drugs as the main means can no longer meet the demand

The reason is that, on the one hand, a large number of antibiotics and chemical drugs are used, leading to the development of drug resistance of pathogens, the control effect is reduced, and the control cost is significantly increased; on the other hand, due to the existence of drug residues, it directly affects the health of consumer groups and public safety.

Therefore, the existing Penaeus vannamei feed is difficult to meet the requirements for use of Penaeus vannamei, which is not conducive to the healthy and sustainable development of the Penaeus vannamei breeding industry.
