Biological puffed feed capable of increasing nutrition of meat quality of river crabs

Abstract

The invention discloses a biological puffed feed capable of increasing the nutrition of meat quality of river crabs. The biological puffed feed consists of the following components in parts by weight: 40-60 parts of a fish soluble extract, 20-35 parts of puffed soybeans, 20-40 parts of corn straw powder, 10-22 parts of kelp powder, 10-16 parts of beef offal powder, 8-15 parts of chicken giblet powder, 11-21 parts of mealworm meal, 5-13 parts of citric acid, 5-9 parts of water lettuce powder, 5-12 parts of red bean powder, 8-13 parts of bean dregs, 5-10 parts of linolenic acid, 5-14 parts of phosphatide, 3-7 parts of fucus, 2-10 parts of dopamine, 6-10 parts of methionine, 3-9 parts of mineral substances, 4-8 parts of vegetable oil, 3-7 parts of table salt, 1-4 parts of carbohydrate and 1-5 parts of probiotics. The feed adopting the formula disclosed by the invention mainly provides protein, vitamins, mineral ion elements, various enzymes and the like desired for growth of the river crabs so as to accelerate the growth of the river crabs, can promote the meat quality of the river crabs in the breeding process, can strengthen the nutrition of the river crabs, can meet the demands of vast consumers, and is nuisanceless to the growth of the river crabs.

Description

technical field [0001] The invention relates to an aquatic feed, in particular to a bio-expanded feed for improving the nutrition of river crab meat. Background technique [0002] River crab, scientific name Chinese mitten crab, is a kind of economic crab. River crab is loved by Chinese people because of its delicious meat, rich nutrition and unique flavor. The size and color of commercial crabs directly affect the sales price, and the nutritional content of the edible part determines the flavor and quality of commercial crabs. The carapace formed by the combination of the crab's head and chest is square and hard. There is a pair of eyes on the front of the body, and two pairs of very sharp crab teeth on the side. The first pair of appendages of the crab are called chelicerae, and the surface is covered with fluff; after the chelicerae, there are 4 pairs of walking legs, the sides are flat and long, and the abdominal limbs have degenerated. For river crabs, male and fema...

Problems solved by technology

[0003] River crab is the freshwater crab with the largest output in my country. It is deeply loved by consumers because of its high nutritional value and delicious taste. It has become an important aquaculture species in the Yangtze River Basin. However, the existing river crab feed has high cost, insufficient nutrition, and Defects such as poor immunity and low survival rate lead to low nutritional value of the crabs that are fed, and the low survival rate results in low economic benefits.
