Embodiment Construction

[0014] A high-protein crab feed additive for improving the nutritional value of crab meat, which is made of the following raw materials in parts by weight: distiller's grains 40, fresh apple pomace 30, camellia oil 6, pumpkin seeds 15, sugar 8, potatoes 30, pigskin 20, Shiitake mushroom 15, Aspergillus niger, yeast, NH4NO3, compound protease, appropriate amount of water.

[0015] According to claims 1, the nutritional value of crab meat and the high-protein crab feed additive are improved, and the specific steps of the preparation method are as follows:

[0016] (1) Put fresh apple pomace into NH4NO3 after aseptic operation, then make a bacterial suspension with cultured Aspergillus niger and yeast with sterile water, mix with the above materials and culture at 28°C for 3 days to obtain fermentation apple pomace;

[0017] (2) the distiller's grains are made into powder after the power is 480W, the thickness of the distiller's grain layer is 2.8cm, and the pulse ratio is 6.625...

Abstract

The invention discloses a high-protein crab feed additive capable of improving nutritional value of crab meat. The feed additive is prepared from, by weight, 40-50 parts of distillers' grains, 30-40 parts of fresh apple residues, 6-7 parts of camellia seed oil, 15-20 parts of pumpkin seeds, 8-11 parts of white sugar, 30-35 parts of potatoes, 20-25 parts of pig skin, 15-20 parts of lentinula edodes and a proper amount of aspergillus niger, saccharomycetes, NH4NO3, composite protease and water. The feed additive has the advantages that quick growth of crabs can be promoted, the feed conversion rate is increased, nutrients in crab meat are increased, little feed is wasted, and water quality is less polluted.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a high-protein crab feed additive for improving the nutritional value of crab meat. Background technique [0002] "Research on Feed Protein Production by Fermentation of Fresh Apple Pomace" mentioned that my country's annual apple production is close to 20 million tons, and more than 1 million tons of apple pomace are discharged every year during apple processing. At present, only a small amount of apple pomace is used for deep processing and directly as feed, and most of them are used for composting or discarded, resulting in serious waste of resources and environmental pollution. Apple pomace contains a certain amount of nutrients such as protein, sugar, pectin, cellulose and hemicellulose, vitamins and mineral elements, and is a good nutritional substrate for microorganisms. However, as animal feed, its protein content is low, which affects Utilization of other ingredients. The...
