Abstract

The invention discloses an easily absorbed crab feed and a preparation method thereof. The easily absorbed crab feed comprises the following raw materials in parts by weight: 7-10 parts of fermented soybeans, 60-65 parts of fermented green grass, 15-18 parts of spinach, 10-20 parts of corn, 23-40 parts of shrimps, 20-30 parts of silkworm chrysalis, 40-50 parts of fishes, 10-20 parts of cod liver oil, 0.2-0.8 part of vitamin D and 0.8-1.2 part of growth promoting agent, wherein the growth promoting agent comprises 40 percent of glycine-iron, 40 percent of zinc methionine and 20 percent of opioid peptide in weight ratio. Compared with the prior art, the prepared crab feed is rich in proteins and calcium; due to the added vitamin D, the calcium absorption of the crabs is promoted and the calcium conversion rate is improved; and the fermented green grass is rich in probiotics, which facilitates the absorption of proteins by the crabs and the improvement of the crab yield.

Description

technical field

[0001] The invention relates to the field of crab breeding, in particular to an easily absorbable crab feed and a preparation method thereof. Background technique

[0002] Crab is a kind of crustacean. It lives in water and has extremely high requirements on water quality. The meat is delicious and nutritious, so it is very popular with diners. Therefore, many farmers will breed crabs. However, the existing crab feed lacks sufficient protein and calcium, and the conversion rate of the crab to protein and calcium in the food is low, so that the crab cannot grow out of the shell as soon as possible, and the protein content in the crab body is greatly reduced. Therefore, it is necessary to provide a New crab feed to solve the above problems. Contents of the invention

[0003] The object of the present invention is to provide an easily absorbable crab feed which is rich in nutrition and convenient for crabs to absorb and convert protein and calcium and a prepa...

Embodiment Construction

[0018] The present invention will be further described below in conjunction with specific embodiments.

[0019] An easy-to-absorb crab feed, comprising the following raw materials in parts by weight: 7-10 parts of tempeh, 60-65 parts of fermented grass, 15-18 parts of spinach, 10-20 parts of corn, 23-40 parts of shrimp, and 20-20 parts of silkworm chrysalis 30 parts, 40-50 parts of fish, 10-20 parts of cod liver oil, 0.2-0.8 parts of vitamin D and 0.8-1.2 parts of growth-promoting agent, and the weight ratio of each component in the growth-promoting agent is iron glycinate 40%, zinc methionine 40%, opioid peptide 20%.

[0020] In a preferred embodiment of the present invention, the parts by weight of each raw material are as follows: 7 parts of tempeh, 60 parts of fermented grass, 15 parts of spinach, 10 parts of corn, 23 parts of shrimp, 20 parts of silkworm chrysalis, 40 parts of fish, 10 parts of cod liver oil part, 0.2 part of vitamin D and 0.8 part of growth promoter.
