Nutrient feed for lobsters and preparation method of nutrient feed

Abstract

The invention belongs to the technical field of fish feeds, and particularly relates to a nutrient feed for lobsters and a preparation method of the nutrient feed. The nutrient feed comprises the following compositions in parts by mass: 68-77 parts of soybean meal, 54-68 parts of rapeseed meal, 51-63 parts of shrimp skin, 43-49 of wheat, 39-43 parts of sorghum, 20-32 parts of soybean oil, 18-21 parts of phospholipid oil, 17-21 parts of animal liver, 21-26 parts of calcium hydrogen phosphate, 19-28 parts of pakchoi leaves, 20-29 parts of salt, 21-28 parts of distiller's grains, 15-21 parts of kelp powder, 13-17 parts of konjac flour, 7-11 parts of garlic, 7-13 parts of yeast powder, 12-18 parts of eclosion hormone, 8-11 parts of biological enzymes, 7-11 parts of TMAO and 4-6 parts of DMPT.The obtained feed is not only rich in nutrients such as protein, amino acids, macro-elements and microelements and comprehensively provides substances required from lobsters, but also has a diet inducing effect and can improve the appetite of lobsters, promote feed intake of lobsters, shorten the growth cycle and promote shelling.

Description

technical field [0001] The invention belongs to the technical field of fish feed, and in particular relates to a nutritious feed for lobster and a preparation method thereof. Background technique [0002] Lobsters are native to Central and South America and northeastern Mexico.

Problems solved by technology

However, as we all know, the edible rate of hard-shell lobster is low, and a large amount of waste is generated, and the recycling rate of lobster waste in my country is very low, causing great pressure on the environment

The soft-shell lobster has more edible parts and less waste, but due to the self-cannibalism of lobsters, it brings certain difficulties to the production of soft-shell lobsters.
