Compound feed for improving immunity of lobsters and preparation method of compound feed

Abstract

The invention discloses a compound feed for improving immunity of lobsters. The compound feed comprises the following raw materials in parts by weight: 30-45 parts of soybean flour, 25-38 parts of corn flour, 20-28 parts of sesame meal, 10-13 parts of duckweed, 12-16 parts of sargassum fusiforme, 9-15 parts of yeast powder, 15-24 parts of silkworm chrysalis meal, 8-17 parts of blood powder, 5-11 parts of ceracris kiangsu, 5-9 parts of vegetable oil, 2-7 parts of sunflower seeds, 5-9 parts of small red beans, 2-5 parts of calcium formate, 2-3 parts of calcium hydrogen phosphate, 3-5 parts of an immunizing agent, 0.5-1 part of a reinforcing agent and 20-30 parts of water. The invention also discloses a preparation method of the compound feed for improving the immunity of the lobsters. The compound feed provided by the invention comprehensively considers requirements on different kinds of nutrients in a lobster growth process, realizes reasonable matching, and improves the comprehensive immunity of the lobsters while meeting comprehensive intake of nutrients of the lobsters, thereby increasing survival rate and quality of the lobsters and reducing production costs.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a compound feed for improving lobster immunity and a preparation method thereof. Background technique [0002] Lobster is also known as prawn, faucet shrimp, shrimp head, sea shrimp, etc. It has a thick head and chest, a hard shell, colorful colors, a short abdomen, a body length of generally 20-40 cm, and a weight of about 0.5 kg.

Problems solved by technology

However, the existing ecological feed is limited in supply and has a single component, which cannot meet the growth requirements of ecologically cultured lobsters. In the process of lobster farming, there are defects such as low disease resistance and slow growth of lobsters, which limits the industrial scale of high-quality lobsters. , restricting people's large demand for lobsters, the production of lobster ecological feed that meets the requirements of lobsters and can be supplied in large quantities has become a key link in the production of high-quality lobsters
