Panopea-abrupta feed additive

Abstract

The invention provides a panopea-abrupta feed additive, and belongs to the field of aquaculture feed. The feed additive comprises water-soluble chitin, an artocarpus heterophyllus leaf flavonoid extract, gamma-aminobutyric acid, sodium butyrate and fly-maggot powder; the water-soluble chitin is obtained in a manner that chitin is extracted from an animal shell through acids and alkalis with a microwave heating method, and then the water-soluble chitin is formed under the alkalization effect of concentrated alkaline and an exciting agent; the exciting agent comprises cinnamyl alcohol and p-cresol. The panopea-abrupta feed additive is high in effective constituent activity and stability, poor in crystallinity, high in solubleness and reconcilability, high in storability and low in productioncost, and is capable of increasing the survival rate of animals and edibility, increasing the feed utilization rate and promoting reinforcement of nutrition metabolism, an intestinal function and immune and antimicrobial abilities; waste resources are fully used in the preparing method, temperature rising is high, time consuming is short, the reaction deacetylation degree is high, the reaction conversion rate and the yield are high, and the resource utilization rate is increased.

Description

technical field [0001] The invention belongs to the field of aquaculture feed, in particular to a geoduck feed additive. Background technique [0002] Geoduck: The biological name is Pacific mud clam, also known as emperor clam and goddess clam, and the seafood product name is "geeoduck". The two shells are the same size, thin and brittle, with serrations, subshells, and water pipes (also called tentacles) at the front end. It is the largest known burrowing bivalve. Native to the North Pacific coast of the United States and Canada. Because of its large and fleshy siphon, which resembles an elephant's trunk (geeoduck), it is known as "geoduck". The meat production rate of geoduck is as high as 60-70%, and the main edible part is the aqueduct muscle, which accounts for 30-35% of the total consumption. Every 100 grams contains 81 kcal of calories, 14.4 grams of protein, and 1.3 grams of fat. It is rich in Highly unsaturated fatty acids, taurine, and polysaccharides in the bo...

Problems solved by technology

In terms of animal feeding, the use of antibiotics and hormones as feed additives has played an important role in improving animal production capacity, but there are many disadvantages in large-scale use, such as causing the imbalance of normal gastrointestinal flora, reducing the level of immune function, and causing pathogens. Microorganisms produce drug resistance and drug residues in animal products, which threaten human health and cause environmental pollution, etc.
