Special compound feed for litopenaeus vannamei

Abstract

The invention relates to a special compound feed for litopenaeus vannamei. The feed is composed of following components in percentage by weight: 18 to 24% of steam fish meal, 17 to 22% of soybean meal, 15 to 24% of peanut meal, 2 to 4% of spray-dried animal blood cells, 2 to 4% of squid paste, 2 to5% of yeast extract, 20 to 25% of flour, 2 to 3% of fish oil, 1 to 2% of soybean oil, 1.0% of shrimp multi-vitamin, 2.0% of shrimp multi-mineral and 1.0% of litopenaeus vannamei special feed addictive, and the sum of the components mentioned above is 100%. The nutrition composite of the compound feed is obtained from numerous tests according to the nutrition need of litopenaeus vannamei, can fully satisfy the nutrition need of litopenaeus vannamei, improves the immunity and disease preventing ability of litopenaeus vannamei, and promotes the healthy growth of litopenaeus vannamei.

Description

technical field [0001] The invention relates to a feed for aquaculture, in particular to a special compound feed 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 sea shri...

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.
