Immunopotentiation type penaeus vannamei feed and preparation method thereof

Abstract

The invention provides an immunopotentiation type penaeus vannamei feed and a preparation method thereof. The feed comprises the following components in parts by weight: 20-25 parts of fish meal, 12-23 parts of soybean meal, 10-15 parts of peanut meal, 15-25 parts of flour, 1-5 parts of shrimp shell powder, 0-7 parts of beer yeast, 2-5 parts of fermented soybean meal, 1-4 parts of fish oil, 0-1.5parts of soybean oil, 0.5-3 parts of soybean lecithin, 0-0.5 part of cholesterol, 0.2-0.4 part of a composite immunopotentiating agent, 1-5 parts of composite vitamins, 1-3 parts of composite mineralsalt, 0.6-1.0 part of composite amino acids and 0.8-1.2 part of an adhesive. The feed can effectively enhance the immunity and the disease resistance of penaeus vannamei, is low in feed coefficient, balanced and comprehensive in nutrients, high in food calling properties and good in stability in water.

Description

technical field [0001] The invention relates to the technical field of aquaculture feed, in particular to an immune-enhancing type Penaeus vannamei feed and a preparation method thereof. Background technique [0002] Vannamei is an important marine and brackish water cultured shrimp in my country. Because of its delicious meat, high nutritional value and large economic benefits, it has broad market prospects. With the continuous deterioration of the breeding environment, the unreasonable increase of the breeding density, the destruction of the germplasm resources of prawns and many other factors, the large-scale and frequent occurrence of diseases has resulted. In aquaculture, diseases often lead to low survival rate of prawns, high aquaculture costs, and bring huge economic losses to shrimp farmers. At the same time, the abuse of antibiotics will also lead to drug resistance of bacteria, inhibit the immunity of Penaeus vannamei, and indirectly affect the environment and h...

Problems solved by technology

[0003] However, the current research on immunopotentiators in prawn farming is still incomplete. Different types of immunopotentiators have different immune regulation mechanisms and have different effects on the growth of Penaeus vannamei, and the immunopotentiators will be affected by different additives when exerting their immune regulation effects. The effect of high dose, long-term use of immune enhancer may cause immune fatigue phenomenon
